Answer 1

Main answer :A savings account with an initial deposit of $1500 will have a balance of $2017.84 after five years with an interest rate of 5% compounded annually.

Supporting explanation: In the given problem, the principal amount is $1500. We are supposed to find the balance after five years with an interest rate of 5% compounded annually.

We can use the formula for compound interest to find the balance. The formula for compound interest is given by the following :Future Value = Present Value * (1 + (Interest Rate / n))^(n * Time) .Here ,Present Value (P) = $1500Interest Rate (r) = 5% or 0.05 (decimal)Time (t) = 5 years n = number of times compounded annually = 1 (annually)Using these values in the formula, we get: Future Value = $1500 * (1 + (0.05 / 1))^(1 * 5)Future Value = $1500 * (1.05)^5Future Value = $2017.84Therefore, the balance after five years will be $2017.84.

use a 2-year weighted moving average to calculate forecasts for the years 1992-2002, with the weight of 0.7 to be assigned to the most recent year data. ("sumproduct" function must be used.)

Answers

The weighted moving average formula with weights of 0.3 and 0.7 can be calculated using the AVERAGE and SUMPRODUCT functions in Excel. This formula can be used to calculate forecasted values for a range of years.

To use a 2-year weighted moving average to calculate forecasts for the years 1992-2002 with the weight of 0.7 assigned to the most recent year data, we can use the SUMPRODUCT function.
First, we need to create a table that includes the years 1990-2002 and their corresponding data points. Then, we can use the following formula to calculate the weighted moving average:
=(0.3*AVERAGE(B2:B3))+(0.7*B3)
This formula calculates the weighted moving average for each year by taking 30% of the average of the data for the previous two years (B2:B3) and 70% of the data for the most recent year (B3). We can then drag the formula down to calculate the forecasted values for the remaining years.
The SUMPRODUCT function can be used to simplify this calculation. The formula for the weighted moving average using SUMPRODUCT would be:
=SUMPRODUCT(B3:B4,{0.3,0.7})
This formula multiplies the data for the previous two years (B3:B4) by their respective weights (0.3 and 0.7) and then sums the products to calculate the weighted moving average for the most recent year. We can then drag the formula down to calculate the forecasted values for the remaining years.
In summary, the weighted moving average formula with weights of 0.3 and 0.7 can be calculated using the AVERAGE and SUMPRODUCT functions in Excel. This formula can be used to calculate forecasted values for a range of years.

A six-pole motor has a coil span of ______. A) 60 B) 90 C) 120 D) 180.

Answers

The correct option: A) 60 . Thus, the coil span of a six-pole motor is 60 degrees, which means that the coil sides connected to the same commutator segment are 60 electrical degrees apart.

The coil span of a motor is the distance between the two coil sides that are connected to the same commutator segment.

The coil span of a six-pole motor can be calculated by dividing the electrical angle of the motor by the number of poles. Since a full electrical cycle is equal to 360 degrees, the electrical angle of a six-pole motor is 360/6 = 60 degrees. Therefore, the coil span of a six-pole motor is 60 degrees.The answer to the question is A) 60. This means that the coil sides connected to the same commutator segment are 60 electrical degrees apart. It is important to note that the coil span affects the motor's performance, as it determines the back electromotive force (EMF) and the torque produced by the motor. A smaller coil span results in a higher back EMF and lower torque, while a larger coil span results in a lower back EMF and higher torque.In conclusion, the coil span of a six-pole motor is 60 degrees, which means that the coil sides connected to the same commutator segment are 60 electrical degrees apart. Understanding the coil span is crucial for designing and analyzing motor performance.

how fast must a meterstick be moving if its length is measured to shrink to 0.737 m?

Answers

The meterstick must be moving at a velocity of approximately 0.836 times the speed of light (or about 251,547,246 m/s) for its length to be measured as 0.737 m.

According to this theory, the length of an object moving relative to an observer appears to be shorter than its rest length. The amount of length contraction depends on the relative velocity between the observer and the object, as well as the direction of motion.

The formula for length contraction is given by:

[tex]L' = L \times \sqrt{(1 - v^2/c^2)}[/tex]

where L is the rest length of the object, L' is its length as measured by the observer, v is the relative velocity between the observer and the object, and c is the speed of light.

In this case, we are given that the measured length of the meterstick is 0.737 m. We can assume that the rest length of the meterstick is the standard length of a meterstick, which is 1.0 m. We want to find the velocity v at which this length contraction occurs.

So, we can rearrange the formula above to solve for v:

[tex]v = c \times \sqrt{(1 - (L'/L)^2)}[/tex]

Plugging in the values given, we get:

[tex]v = c \times \sqrt{(1 - (0.737/1.0)^2)} \\= c \times \sqrt{(1 - 0.542^2)} \\= c \times \sqrt{v} \\= 0.836c[/tex]

16. suppose that the probability that a cross between two varieties will express a particular gene is 0.20. what is the probability that in 8 progeny plants, four or more plants will express the gene?

Answers

The probability that in 8 progeny plants, four or more plants will express the gene is approximately 0.892.

To find the probability that four or more plants will express the gene, we sum up the probabilities of these individual outcomes:P(X ≥ 4) = P(X = 4) + P(X = 5) + P(X = 6) + P(X = 7) + P(X = 8). Calculating these probabilities and summing them up will give you the final result.

To calculate the probability that in 8 progeny plants, four or more plants will express the gene, we can use the binomial probability formula.

The binomial probability formula is given by:

[tex]P(X = k) = C(n, k) * p^k * (1 - p)^(n - k)[/tex]

Where:

P(X = k) is the probability of getting exactly k successes

n is the total number of trials

k is the number of successful outcomes

p is the probability of success in a single trial

C(n, k) is the number of combinations of n items taken k at a time (given by n! / (k! * (n - k)!)

In this case, we want to find the probability of getting four or more plants expressing the gene in 8 progeny plants. Let's calculate it step by step:

[tex]P(X = 4) = C(8, 4) * 0.20^4 * (1 - 0.20)^(8 - 4)\\P(X = 5) = C(8, 5) * 0.20^5 * (1 - 0.20)^(8 - 5)\\P(X = 6) = C(8, 6) * 0.20^6 * (1 - 0.20)^(8 - 6)\\P(X = 7) = C(8, 7) * 0.20^7 * (1 - 0.20)^(8 - 7)\\P(X = 8) = C(8, 8) * 0.20^8 * (1 - 0.20)^(8 - 8)[/tex]

f(x)=)7/4)x^4+(14/3)x^3+(−7/2)x^2−14x
There are three critical points. If we call them c1,c2, and c3, with c1 c1=
c2=
c3 =
Is f a maximum or minimum at the critical points?
At c1, f is? A)Local Max B)Local Min C)Neither
At c2, f is? A)Local Max B)Local Min C)Neither
At c3, f is? A)Local Max B)Local Min C)Neither

Answers

The critical points are:

At c1 ≈ -2.108, f is Local Min.

At c2 ≈ -0.416, f is Neither.

At c3 ≈ 1.524, f is  Local Min.

To find the critical points, we need to find where the derivative of the function is equal to zero or undefined. Let's calculate the derivative:

[tex]f'(x) = 7x^3 + 14x^2 - 7x - 14[/tex]

To find the critical points, we set f'(x) equal to zero and solve for x:

[tex]7x^3 + 14x^2 - 7x - 14 = 0[/tex]

We can simplify this equation by factoring out a common factor of 7:

[tex]7(x^3 + 2x^2 - x - 2) = 0[/tex]

Now, we have a cubic equation. Unfortunately, the roots of this equation cannot be found easily by factoring or simple methods. We can approximate the roots using numerical methods or calculators.

Using numerical methods or a calculator, we find the approximate values of the three critical points:

c1 ≈ -2.108

c2 ≈ -0.416

c3 ≈ 1.524

To determine the nature of each critical point, we apply the First Derivative Test. We evaluate the sign of the derivative on either side of each critical point:

For c1 ≈ -2.108:

Evaluate f'(-3): f'(-3) ≈ -77.364 < 0

Evaluate f'(-2): f'(-2) ≈ 4.000 > 0

Since the sign changes from negative to positive, c1 ≈ -2.108 corresponds to a local minimum.

For c2 ≈ -0.416:

Evaluate f'(-1): f'(-1) ≈ -20.083 < 0

Evaluate f'(0): f'(0) ≈ -14.000 < 0

Since the sign does not change, c2 ≈ -0.416 does not correspond to a local maximum or minimum (neither).

For c3 ≈ 1.524:

Evaluate f'(1): f'(1) ≈ -11.083 < 0

Evaluate f'(2): f'(2) ≈ 42.000 > 0

Since the sign changes from negative to positive, c3 ≈ 1.524 corresponds to a local minimum.

Therefore, the answers are:

At c1 ≈ -2.108, f is B) Local Min.

At c2 ≈ -0.416, f is C) Neither.

At c3 ≈ 1.524, f is B) Local Min.

The profit for a certain company is given by P= 230 + 20s - 1/2 s^2 R where s is the amount (in hundreds of dollars) spent on advertising. What amount of advertising gives the maximum profit?A. $10B. $40C. $1000D. $4000

Answers

Answer choice C ($1000) is the most plausible option, as it corresponds to a relatively high value of R.

We can find the maximum profit by finding the value of s that maximizes the profit function P(s).

To do this, we first take the derivative of P(s) with respect to s and set it equal to zero to find any critical points:

P'(s) = 20 - sR = 0

Solving for s, we get:

s = 20/R

To confirm that this is a maximum and not a minimum or inflection point, we can take the second derivative of P(s) with respect to s:

P''(s) = -R

Since P''(s) is negative for any value of s, we know that s = 20/R is a maximum.

Therefore, to find the amount of advertising that gives the maximum profit, we need to substitute this value of s back into the profit function:

P = 230 + 20s - 1/2 s^2 R

P = 230 + 20(20/R) - 1/2 (20/R)^2 R

P = 230 + 400/R - 200/R

P = 230 + 200/R

Since R is not given, we cannot find the exact value of the maximum profit or the corresponding value of s. However, we can see that the larger the value of R (i.e. the more revenue generated for each unit of advertising spent), the smaller the value of s that maximizes profit.

So, answer choice C ($1000) is the most plausible option, as it corresponds to a relatively high value of R.

let f be [a,b] to r be a continuous function and integral f = 0. prove that there exists a c in [a,b] such that f(c)= 0

Answers

By applying the Intermediate Value Theorem for continuous functions, we can conclude that if the integral of a continuous function f over the interval [a, b] is equal to zero, then there exists at least one point c in the interval [a, b] where f(c) is also equal to zero.

To prove that there exists a point c in the interval [a, b] where f(c) is equal to zero, we will make use of the Intermediate Value Theorem.

The Intermediate Value Theorem states that if a function f is continuous on a closed interval [a, b] and f(a) and f(b) have opposite signs (i.e., f(a) < 0 and f(b) > 0, or f(a) > 0 and f(b) < 0), then there exists at least one point c in the interval (a, b) where f(c) is equal to zero.

In our case, we are given that the integral of f over the interval [a, b] is equal to zero, i.e., ∫[a,b] f(x) dx = 0. Since the integral represents the signed area under the curve of f(x), the fact that the integral is zero indicates that the positive and negative areas cancel each other out.

Now, let's assume, for the sake of contradiction, that there does not exist any point c in the interval [a, b] where f(c) is equal to zero. This would mean that f(x) maintains a constant sign (either positive or negative) throughout the interval [a, b].

If f(x) is always positive or always negative, then the integral of f over [a, b] cannot be zero, as it would represent a nonzero positive or negative area under the curve. This contradicts the given condition that the integral is equal to zero.

Therefore, by contradiction, we can conclude that there must exist at least one point c in the interval [a, b] where f(c) is equal to zero. This completes the proof.

use the laplace transform to solve the given initial-value problem. 2y'' 36y' 163y = 0, y(0) = 2, y'(0) = 0

Answers

Answer : the solution to the initial-value problem is y(t) = 2e^(-3t) + 2e^(-27t), where t >= 0.

Initial-value problem using Laplace transforms, we'll follow these steps:

1. Take the Laplace transform of the differential equation.

2. Apply the initial conditions to obtain the transformed equation.

3. Solve the transformed equation for the Laplace transform of the unknown function.

4. Take the inverse Laplace transform to find the solution in the time domain.

Step 1: Taking the Laplace transform of the differential equation:

We have the differential equation: 2y'' + 36y' + 163y = 0

Taking the Laplace transform of each term using the properties of the Laplace transform, we get:

2[s^2Y(s) - sy(0) - y'(0)] + 36[sY(s) - y(0)] + 163Y(s) = 0

Step 2: Applying the initial conditions:

We are given y(0) = 2 and y'(0) = 0. Substituting these values into the transformed equation, we get:

2[s^2Y(s) - 2s] + 36[sY(s) - 2] + 163Y(s) = 0

Step 3: Solving the transformed equation for Y(s):

Rearranging the equation, we have:

(2s^2 + 36s + 163)Y(s) = 4s + 72

Dividing both sides by (2s^2 + 36s + 163), we obtain:

Y(s) = (4s + 72) / (2s^2 + 36s + 163)

Step 4: Taking the inverse Laplace transform:

To find the solution y(t) in the time domain, we need to compute the inverse Laplace transform of Y(s). However, the denominator of Y(s) is a quadratic expression, so we need to perform partial fraction decomposition.

The quadratic expression 2s^2 + 36s + 163 can be factored as (s + 3)(s + 27). Therefore, we can rewrite Y(s) as follows:

Y(s) = (4s + 72) / [(s + 3)(s + 27)]

Using partial fraction decomposition, we express Y(s) as:

Y(s) = A / (s + 3) + B / (s + 27)

To find A and B, we multiply both sides by the denominator and equate the numerators:

(4s + 72) = A(s + 27) + B(s + 3)

Expanding and collecting like terms:

4s + 72 = (A + B)s + 27A + 3B

By comparing coefficients, we get the following system of equations:

A + B = 4    ---(1)

27A + 3B = 72 ---(2)

Solving the system of equations, we find A = 2 and B = 2.

Now we can rewrite Y(s) as:

Y(s) = 2 / (s + 3) + 2 / (s + 27)

Taking the inverse Laplace transform of Y(s) using the table of Laplace transforms, we obtain the solution in the time domain:

y(t) = 2e^(-3t) + 2e^(-27t)

Therefore, the solution to the initial-value problem is y(t) = 2e^(-3t) + 2e^(-27t), where t >= 0.

f[t_2, t_1, t_0] = (f[t_2, t_1] - f[t_1, t_0])/(t_2 - t_0) = (1.7143 - 10)/(6.0 - 1.0) = -1.6571 m/s^2

Therefore, the acceleration at t=4 seconds is approximately -1.6571 m/s^2.

At t=10 seconds:

The first-order divided difference for velocity between t=9.0 and t=12.0 is:

f[t_2, t_1] = (V(t_2) - V(t_1))/(t_2 - t_1) = (30 - 22)/(12.0 - 9.0) = 2.6667 m/s^2

The first-order divided difference for velocity between t=6.0 and t=9.0 is:

f[t_1, t_0] = (V(t_1) - V(t_0))/(t_1 - t_0) = (22 - 18)/(9.0 - 6.0) = 1.3333 m/s^2

The second-order divided difference for velocity between t=9.0, t=12.0, and t=6.0 is:

f[t_2, t_1, t_0] = (f[t_2, t_1] - f[t_1, t_0])/(t_2 - t_0) = (2.6667 - 1.3333)/(12.0 - 6.0) = 0.2222 m/s^2

Therefore, the acceleration at t=10 seconds is approximately 0.2222 m/s^2.

In triangle LMN,LM=8cm,MN=6cm and LMN=90°. X and Y are the midpoints of MN and LN respectively. Determine YXN and YN​

Answers

The length of YXN is √34 cm, and YN is 5 cm, using the Pythagoras theorem and the midpoint theorem. The triangle LMN is right-angled at L, LM, and LN are the legs of the triangle, and MN is its hypotenuse.

We know that X and Y are the midpoints of MN and LN, respectively. Therefore, from the midpoint theorem, we know that.

MY=LY = LN/2 (as Y is the midpoint of LN) and

MX=NX= MN/2 (as X is the midpoint of MN).

We have given LM=8cm and MN=6cm. Now we will use the Pythagoras theorem in ΔLMN.

Using Pythagoras' theorem, we have,

     LN2=LM2+MN2

        LN = 82+62=100

       =>LN=10 cm

As Y is the midpoint of LN, YN=5 cm

MX = NX = MN/2 = 6/2 = 3 cm

Therefore, ΔNYX is a right-angled triangle whose hypotenuse is YN = 5 cm. MX = 3 cm

From Pythagoras' theorem, NY2= YX2+ NX2

= 52+32= 34

=>NY= √34 cm

Therefore, YXN is √34 cm, and YN is 5 cm.

Thus, we can conclude that the length of YXN is √34 cm, and YN is 5 cm, using the Pythagoras theorem and the midpoint theorem.

Given the linear programMax 3A + 4Bs.t.-lA + 2B < 8lA + 2B < 1224 + 1B < 16A1 B > 0a. Write the problem in standard form.b. Solve the problem using the graphical solution procedure.c. What are the values of the three slack variables at the optimal solution?

Answers

The values of the three slack variables at the optimal solution are x = 4, y = 0, and z = 20.

a. To write the problem in standard form, we need to introduce slack variables. Let x, y, and z be the slack variables for the first, second, and third constraints, respectively. Then the problem becomes:

Maximize: 3A + 4B
Subject to:
-lA + 2B + x = 8
lA + 2B + y = 12
24 + B + z = 16A
B, x, y, z >= 0

b. To solve the problem using the graphical solution procedure, we first graph the three constraint lines: -lA + 2B = 8, lA + 2B = 12, and 24 + B = 16A.

We then identify the feasible region, which is the region that satisfies all three constraints and is bounded by the x-axis, y-axis, and the lines -lA + 2B = 8 and lA + 2B = 12. Finally, we evaluate the objective function at the vertices of the feasible region to find the optimal solution.

After graphing the lines and identifying the feasible region, we find that the vertices are (0, 4), (4, 4), and (6, 3). Evaluating the objective function at each vertex, we find that the optimal solution is at (4, 4), with a maximum value of 3(4) + 4(4) = 24.

c. To find the values of the slack variables at the optimal solution, we substitute the values of A and B from the optimal solution into the constraints and solve for the slack variables. We get:

-l(4) + 2(4) + x = 8
l(4) + 2(4) + y = 12
24 + (4) + z = 16(4)

Simplifying each equation, we get:

x = 4
y = 0
z = 20

Therefore, the values of the three slack variables at the optimal solution are x = 4, y = 0, and z = 20.

Find the length and width of a rectangle with area 64m that give minimum perimeter

Answers

To find the length and width of a rectangle with an area of 64m² that gives the minimum perimeter, we can use calculus. The length and width should be 8m and 8m, respectively.

Let's assume the length of the rectangle is L and the width is W. The perimeter of the rectangle is given by P = 2L + 2W. We are given that the area of the rectangle is 64m², so we have the equation LW = 64.

To find the minimum perimeter, we can use calculus. We need to minimize P with respect to L while keeping the area constant. We can express L in terms of W using the area equation: L = 64/W. Substituting this into the perimeter equation, we have P = 2(64/W) + 2W.

To find the minimum value of P, we can take the derivative of P with respect to W and set it equal to zero. The derivative of P is dP/dW = -128/W^2 + 2. Solving dP/dW = 0, we find W = 8. Substituting this value back into the area equation, we get L = 8.

Therefore, the length and width of the rectangle that give the minimum perimeter with an area of 64m² are 8m and 8m, respectively.

Calculate the double integral. ∬R5xsin(x+y) dA, R=(0, π6)×(0, π3)

Answers

We need to evaluate the double integral:

∬R 5x sin(x+y) dA, R=(0, π/6)×(0, π/3)

Using iterated integrals, we have:

∬R 5x sin(x+y) dA = ∫[0, π/6] ∫[0, π/3] 5x sin(x+y) dy dx

= ∫[0, π/6] [(-5/2)x cos(x+y)]|[0,π/3] dx

= ∫[0, π/6] [(-5/2)x cos(x+π/3) + (5/2)x cos(x)] dx

= (-5/2) ∫[0, π/6] x cos(x+π/3) dx + (5/2) ∫[0, π/6] x cos(x) dx

Let's evaluate each integral separately:

∫[0, π/6] x cos(x+π/3) dx

= ∫[π/3, 2π/3] (u-π/3) cos(u) du   (where u = x+π/3)

= ∫[π/3, 2π/3] u cos(u) du - (π/3) ∫[π/3, 2π/3] cos(u) du

= sin(2π/3) - sin(π/3) - (π/3)(sin(2π/3) - sin(π/3))

= -π/3√3

Similarly,

∫[0, π/6] x cos(x) dx = sin(π/6)/2 = 1/4

Therefore,

∬R 5x sin(x+y) dA = (-5/2) (-π/3√3) + (5/2)(1/4) = (5π)/(6√3)

Hence, the value of the double integral is (5π)/(6√3).

Consider an angle, and a circle centered at the angle's vertex. The circle's radius is 6 cm long and the angle subtends an arc that is 15.6 cm long. a. What is the angle's measure in radians? radians Preview b. A second circle is centered at the angle's vertex, and the circle's radius is 12 cm long. The subtended arc is how long in cm? (Draw a diagram to help you!) cm

Answers

The subtended arc for the second circle is 31.2 cm long.

Given a circle with a radius of 6 cm and a subtended arc of 15.6 cm, we can find the angle's measure in radians using the formula: angle (in radians) = arc length/radius. Plugging in the values, we get angle = 15.6 cm / 6 cm = 2.6 radians.
For the second circle with a radius of 12 cm, we can find the subtended arc length by rearranging the formula: arc length = angle (in radians) * radius. Using the angle of 2.6 radians, we get arc length = 2.6 radians * 12 cm = 31.2 cm. Therefore, the subtended arc for the second circle is 31.2 cm long.

Feliz Navidad (FN) manufacturers Christmas wreaths. The Christmas wreaths are sold for $600, and cost $465 to make. Based on market demand, they anticipate being able to sell 1,200 wreaths. An alternative is for FN to sell garland, which is an intermediate product. FN can sell the garland for $440. At the point that the garland is created only $315 of costs are incurred. The demand for garlands are expected to be 1,400 units

Answers

The profit from selling garlands is higher than the profit from manufacturing wreaths. FN should focus on selling garlands instead of wreaths.

To compare the profitability of manufacturing wreaths and garlands, we need to calculate the profit for each product.

Profit from manufacturing wreaths:

Revenue from selling 1,200 wreaths = 1,200 x $600 = $720,000

Total cost of making 1,200 wreaths = 1,200 x $465 = $558,000

Profit from selling 1,200 wreaths = $720,000 - $558,000 = $162,000

Profit from selling garlands:

Revenue from selling 1,400 garlands = 1,400 x $440 = $616,000

Total cost of making 1,400 garlands = $315 + (1,400 x $315) = $441,315

Profit from selling 1,400 garlands = $616,000 - $441,315 = $174,685

Answers

The value of a rare coin in dollars can be approximated by the model Y = 0.25(1.06)^t, where t represents the number of years since the coin was minted. The model indicates that the value of the coin increases over time.

The given model Y = 0.25(1.06)^t represents an exponential growth model. In this model, the value of the coin is determined by multiplying an initial value of 0.25 dollars by the growth factor (1.06) raised to the power of the number of years since the coin was minted (t).

The growth factor of 1.06 indicates that the value of the coin increases by 6% per year. Each year, the value of the coin is multiplied by 1.06, resulting in continuous growth over time.

The initial value of 0.25 dollars represents the starting value of the coin when it was minted. As time passes, the value of the coin increases exponentially according to the model.

Therefore, the given model provides an approximation of the value of the rare coin in dollars based on the number of years since it was minted, with a growth rate of 6% per year.

Answers

The slope of the median-median line for this dataset is 0.8.

To calculate the slope of the median-median line for this dataset, we need to first calculate the medians of both the x and y variables.

The median of the x variable is (15+16+18+19+20+22)/6 = 17.
The median of the y variable is (15+16+18+19+20+22)/6 = 17.

Next, we need to calculate the slopes of all the lines connecting the pairs of medians (x1,y1) and (x2,y2).
(x1,y1) = (15,16), (x2,y2) = (22,20), slope = (20-16)/(22-15) = 0.8
(x1,y1) = (15,16), (x2,y2) = (22,19), slope = (19-16)/(22-15) = 0.75
(x1,y1) = (15,16), (x2,y2) = (22,22), slope = (22-16)/(22-15) = 1.2
(x1,y1) = (15,18), (x2,y2) = (22,20), slope = (20-18)/(22-15) = 0.4
(x1,y1) = (15,18), (x2,y2) = (22,19), slope = (19-18)/(22-15) = 0.1667
(x1,y1) = (15,18), (x2,y2) = (22,22), slope = (22-18)/(22-15) = 0.6667

We then calculate the median of all these slopes to get the slope of the median-median line.

Median slope = (0.4, 0.6667, 0.75, 0.8, 1.2) = 0.8
Therefore, the slope of the median-median line for this dataset is 0.8.
