how to solve 2400 at 10.5% for 5 years

Answers

Answer 1

Answer: 1260

Step-by-step explanation:

To solve for simple interest, we can use the formula:

I = P * r * t

where:

I = interest

P = principal amount

r = interest rate

t = time (in years)

In this case:

P = 2400

r = 10.5% = 0.105 (note that we convert the percentage to a decimal)

t = 5

Substituting these values into the formula, we get:

I = 2400 * 0.105 * 5

I = 1260

Therefore, the simple interest on a principal amount of 2400 at 10.5% for 5 years is 1260.

what percentage of defective lots does the purchaser reject? find it for . given that a lot is rejected, what is the conditional probability that it contained 4 defective components

Answers

The purchaser rejects 26.01% of the lots that contain five or more defective components, and the conditional probability of having four defective components given that the lot was rejected is 0.1653.

How do we calculate the probability?

The percentage of defective lots that the purchaser rejects can be found by using the given formula. We can also calculate the conditional probability of having four defective components, given that the lot was rejected. Here's how to do it.

Let p be the probability that any component is defective. Then the probability that any component is non-defective is 1-p.

According to the given data, a lot is rejected if and only if there are at least five defective components in it. Let q be the probability that a lot is defective, i.e. the probability that there are five or more defective components in a lot.

Then, q = P(X ≥ 5), where X is the number of defective components in the lot. We can find the probability of rejecting a lot by subtracting the probability of accepting the lot from 1. So, we have:

P(reject) = 1 - P(accept)

P(accept) = P(X ≤ 4)

Now, we need to find q. We can do this by using the binomial distribution:

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

where C(n, k) is the number of ways to choose k items out of n items. Here, n = 20 (the number of components in a lot). So,

[tex]q = P(X \geq  5) = 1 - P(X\leq  4) = 1 - [P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4)][/tex]

[tex]q = 1 - [C(20, 0) * p0 * (1-p)20-0 + C(20, 1) * p1 * (1-p)20-1 + C(20, 2) * p2 * (1-p)20-2 + C(20, 3) * p3 * (1-p)20-3 + C(20, 4) * p4 * (1-p)20-4][/tex]

[tex]q = 1 - [1 * p0.2 * (1-0.2)20-0 + 20 * p0.2 * (1-0.2)20-1 + 190 * p0.2 * (1-0.2)20-2 + 1140 * p0.2 * (1-0.2)20-3 + 4845 * p0.2 * (1-0.2)20-4][/tex]

[tex]q = 0.2601[/tex] (rounded to four decimal places)

So, the purchaser rejects 26.01% of the lots that contain five or more defective components.

Now, we need to find the conditional probability that a lot contained four defective components given that it was rejected. Let R be the event that a lot is rejected, and let F be the event that a lot contains four defective components.

Then, we have to find P(F | R), the conditional probability of F given R. We can use Bayes' theorem to find this:

P(F | R) = P(R | F) * P(F) / P(R)

where P(R | F) is the probability of rejecting a lot given that it contained four defective components, P(F) is the prior probability of a lot containing four defective components, and P(R) is the overall probability of rejecting a lot.

[tex]P(F) = C(20, 4) * p4 * (1-p)20-4 = 0.186[/tex]

[tex][tex]P(R) = P(X \geq  5) = q = 0.2601[/tex][/tex]

[tex]P(R | F) = P(X \geq  5 | X = 4) = P(X = 5) / P(X = 4) = C(20, 5) * p5 * (1-p)20-5 / C(20, 4) * p4 * (1-p)20-4[/tex]

[tex]P(R | F) = 0.2308[/tex]

So, we have:

[tex]P(F | R) = P(R | F) * P(F) / P(R)[/tex]

[tex]P(F | R) = 0.2308 * 0.186 / 0.2601[/tex]

[tex]P(F | R) = 0.1653[/tex] (rounded to four decimal places)

Therefore, the conditional probability of having four defective components given that the lot was rejected is 0.1653.

What is commutative law?

Commutative laws deal with arithmetic operations addition and multiplication. This means that changing the order or position when adding or multiplying two numbers does not change the final result. For example, 4 + 5 is 9 and 5 + 4 is also 9. The order in which the two numbers are added does not affect the sum. The same concept applies to multiplication. Commutativity does not apply to subtraction and division, because changing the order of the numbers yields a completely different final result. 

(8x²)(3x²) can be simplified as follows:

(8x²)(3x²) = 8.3.x².x² = (8.3).(x².x²)

an inner city revitalization zone is a rectangle that is twice as long as it is wide. the width of the region is growing at a rate of 32 m per year at a time when the region is 220 m wide. how fast is the area changing at that point in time?

Answers

The area is changing at a rate of 28,160 m²/year at that point in time.

The area of the rectangular region is given by:

A = lw

Where l is the length of the rectangular region and w is the width of the rectangular region.

The width of the rectangular region is given to be 220 m. Therefore, we have the width w = 220 m. The length l of the rectangular region can be found knowing that it is twice as long as it is wide. Therefore, the length of the rectangular region is given by:

l = 2w

l = 2 x 220

l = 440

Therefore, the length l of the rectangular region is 440 m.

At the given point in time, the width of the rectangular region is growing at a rate of 32 m per year. Therefore, we have the rate of change of the width dw/dt to be 32 m per year. We need to find how fast the area of the rectangular region is changing at that point in time. Therefore, we need to find the rate of change of the area of the rectangular region dA/dt.

A = lw

dA/dt = w dl/dt + l dw/dt

dA/dt = 220 d/dt(2w) + 440 dw/dt

dA/dt = 220 x 2 dw/dt + 440 dw/dt

dA/dt = 880 dw/dt

Substitute the value of dw/dt to get:

dA/dt = 880 x 32

dA/dt = 28,160 m²/year

Therefore, the area of the rectangular region has a rate of change of 28,160 m² per year at that point in time.

A series of locks manages the water height along a water source used to produce energy. As the locks are opened and closed, the water height between two consecutive locks fluctuates.
The height of the water at point B located between two locks is observed. Water height measurements are made every 10 minutes beginning at 8:00 a.m.
It is determined that the height of the water at B can be modeled by the function f(x)=−11cos(πx/48 − 5π/12)+28 , where the height of water is measured in feet and x is measured in minutes.
What is the maximum and minimum water height at B, and when do these heights first occur?

Answers

The given function f(x) = -11cos(πx/48 - 5π/12) + 28 models the height of water at point B between two locks, where x is the time in minutes beginning at 8:00 a.m.

The amplitude of the cosine function is 11, and the vertical shift is 28. The argument of the cosine function has a period of 96 minutes, which means that the function repeats itself every 96 minutes.

Therefore, the maximum water height at B is 39 feet and occurs at x = 120 minutes (10:00 a.m.), while the minimum water height at B is 17 feet and occurs at x = 0 minutes (8:00 a.m.). These heights occur because the cosine function attains its maximum value at x = 120 minutes and its minimum value at x = 0 minutes.

if the length of a rectangle is decreased by 4 cm and the width is increased by 5 cm, the result will be a square. the area of this square will be 40cm^2 greater than the area of the rectangle. Find the area of the rectangle.

Answers

Answer: 30 cm^2.

Step-by-step explanation:

Let the original length of the rectangle be l and its width be w. Then, according to the problem:

(l - 4) = (w + 5) (equation 1)

Also, the area of the square is 40 cm^2 more than the area of the rectangle. Mathematically, we can represent this as:

(l - 4 + 5)^2 = lw + 40

Simplifying the left-hand side and substituting equation 1, we get:

l^2 - 2lw + w^2 = lw + 40

l^2 - 3lw + w^2 - 40 = 0

(l - 8)(l - 5) = 0

Therefore, l = 8 or l = 5. If we substitute l = 8 into equation 1, we get:

w = (l - 4) - 5 = -1

This is not a valid solution since the width cannot be negative. Therefore, the only valid solution is l = 5, which gives:

w = (l - 4) + 5 = 6

So the area of the rectangle is:

A = lw = 5 x 6 = 30 cm^2.

Answer:

steps explanations: x - 4 = y + 5 (sides of a square)

(x - 4)(y + 5) = 40

Which gives;

(y + 5) (y + 5) = 40

y² + 10y + 25 = 40

By using the Lagrange multipliers, the two points on the cone that is closest to (14, 8, 0) are:

(7, 4, √65) and (7, 4, -√65)

We want to minimize the distance between the point (14, 8, 0) and the points on the cone z^2 = x^2 + y^2. The distance squared between two points (x_1, y_1, z_1) and (x_2, y_2, z_2) is given by:

d^2 = (x2 - x1)^2 + (y2 - y1)^2 + (z2 - z1)^2

In our case, we want to minimize the distance squared between (14, 8, 0) and a point (x, y, z) on the cone z^2 = x^2 + y^2:

d^2 = (x - 14)^2 + (y - 8)^2 + z^2

Subject to the constraint z^2 = x^2 + y^2. We can use Lagrange multipliers to solve this constrained optimization problem. Let L be the Lagrangian:

L = (x - 14)^2 + (y - 8)^2 + z^2 - λ(z^2 - x^2 - y^2)

Taking the partial derivatives of L with respect to x, y, z, and λ, and setting them to zero, we get:

2(x - 14) - 2λx = 0.....(1)

2(y - 8) - 2λy = 0.....(2)

2z - 2λz = 0.....(3)

z^2 - x^2 - y^2 = 0.....(4)

Simplifying the third equation, we get z(1 - λ) = 0. Since we want to find points where z is not zero, we must have λ = 1. Then, from the first two equations, we get x = 7 and y = 4. Substituting these values into the fourth equation, we get:

z^2 = x^2 + y^2 = 65

If c1 = 2, then c2 = ___
2√3= ____

Answers

First, let's find the function to use for the Newton-Raphson method approximation. We want to find an approximation of 3√7, so we can use f(x) = x^3 - 7 and rewrite it as f(x) = -7 + x^3.

Setting A = B = C = D = 0 in the given function, we get f(x) = x^3 - 7.

Next, we apply the Newton-Raphson method with x1 = 2, which gives us:

x2 = x1 - f(x1) / f'(x1)
x2 = 2 - (2^3 - 7) / (3 * 2^2)
x2 = 2 - (8 - 7) / 12
x2 = 2 - 1/12
x2 = 23/12

Next, we apply the Newton-Raphson method again with x2, which gives us:

x3 = x2 - f(x2) / f'(x2)
x3 = 23/12 - ((23/12)^3 - 7) / (3 * (23/12)^2)
x3 = 23/12 - (12167/20736 - 7) / (3 * 529/144)
x3 = 23/12 - (4337/15552) / (529/48)
x3 = 23/12 - (36/15552)
x3 = 2783/1440

We can continue this process of applying the Newton-Raphson method until we obtain successive approximations that are identical. However, we can stop here and use 2783/1440 as our approximate value for 3√7.

Converting to a decimal approximation, we get:

3√7 ≈ 2.660874...

Rationalizing the denominator, we get:

3√7 ≈ (2783√21) / 1440

Therefore, our final answer is 2√3 = (2 * √3) ≈ 3.464.

A) To solve by the elimination method , we add the left-hand sides and right-hand sides of the two equations separately, as follows,

(x - y) + (x + y) = 7 + 5

2x = 12

x = 6

(x + y) - (x - y) = 5 - 7

2y = -2

y = -1

Therefore, the solution to the system is (x, y) = (6, -1).

B) To solve by the method of elimination, we can multiply the first equation by 2 to eliminate the x term, as follows,

2x + 5y = 3

-4x - 2y = 10

Adding these two equations, we get,

3y = 13

y = 13/3

Substituting y = 13/3 into the first equation, we get,

2x + 5(13/3) = 3

2x = -32/3

Based on the following sorted 20 values for age, the possible split points are {20, 21, 23, 25, 27, 29. 5, 31. 5, 32. 5, 34, 37. 5, 41, 42. 5, 44, 46, 48, 49. 5, 51, 52, 54, 56} (option a).

Option A suggests that the split points are {20, 21, 23, 25, 27, 29.5, 31.5, 32.5, 34, 37.5, 41, 42.5, 44, 46, 48, 49.5, 51, 52, 54, 56}. Notice that every split point falls between two consecutive ages in the original list. For example, the first split point is 20 because it is between 20 and 22. The second split point is 21 because it is between 20 and 22 as well.

Option B suggests that the split points are {21, 23, 25, 27, 29.5, 31.5, 32.5, 34, 37.5, 41, 42.5, 44, 46, 48, 49, 51, 52.5, 54, 56, 57}. Notice that the only difference between this option and Option A is that the last split point is 57 instead of 49.5.

Option C suggests that the split points are {0, 21, 23, 25, 27, 29.5, 31.5, 32.5, 34, 37.5, 41, 42.5, 44, 46, 48, 49, 51, 52.5, 54, 56}. Notice that the first split point is 0, which is not a possible age in the original list.

Option D suggests that the split points are {21, 23, 25, 27, 29.5, 31.5, 32.5, 34, 37.5, 41, 42.5, 44, 46, 48, 49.5, 51, 52.5, 54, 56}. Notice that the only difference between this option and Option A is that the split point after 49 is 49.5 instead of 49.5.

In summary, the correct answer is Option A because it provides all the possible split points that fall between the ages in the original list. When working with split points, it's important to consider the specific context and criteria for dividing the data.

Bernard's rectangular bedroom is 12 feet by 16 feet. What is the diagonal distance from one corner to the opposite corner?

Answers

Answer: 20 feet

Step-by-step explanation: To find the diagonal distance from one corner to the opposite corner of Bernard's rectangular bedroom, we can use the Pythagorean theorem, which states that the square of the length of the hypotenuse (diagonal) of a right triangle is equal to the sum of the squares of the lengths of the other two sides.

In this case, the two other sides are the length and the width of the room, so we have:

diagonal^2 = 12^2 + 16^2

diagonal^2 = 144 + 256

diagonal^2 = 400

Taking the square root of both sides, we get:

diagonal = √400

diagonal = 20 feet

Therefore, the diagonal distance from one corner to the opposite corner of Bernard's rectangular bedroom is 20 feet.

a child who weighs 18kg is to receive motrin (ibuprofen) 8mg/kg by mouth every 4 hours as needed for pain. the label reads 100mg/5mls. how many milliliters will you administer?

Answers

According to the information on what the child should receive ibuprofen, it should be administered to the child 1.6 mL.

What is Ibuprofen?

Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID). It works by inhibiting the body's synthesis of prostaglandins. This aids in the reduction of swelling, pain, and fever. It can also be used to relieve mild to moderate pain caused by menstruation, arthritis, or toothache.

To calculate the amount of milliliters to be administered, we need to use the following formula:

Amount of Motrin = Weight of child (kg) × Dose of Motrin (mg/kg) ÷ Concentration of Motrin (mg/ml)

Where

Weight of child = 18kgDose of Motrin = 8mg/kgConcentration of Motrin = 100mg/5mls

Substitute the given values in the above formula.

Amount of Motrin = 18kg × 8mg/kg ÷ 100mg/5mls= 144mg ÷ 20mg/mls= 7.2mls

Therefore, the amount of Motrin to be administered is 7.2mls.

However, the dosage amount administered is not in 5ml increments. Therefore, we need to round it to one decimal place. Thus, we'll have: Amount of Motrin = 7.2 ml (rounded to one decimal place) = 1.6 ml Answer: 1.6 ml

Mr. Ferrell has feet of a piece of 5/6 cardboard. He wants to cut pieces that are foot long. 1/8 How many pieces can he make?

Answers

Mr. Ferrell can cut 6 and 2/3 pieces that are one-eighth foot long from a 5/6 foot long piece of cardboard.

What is common factor?

A number is said to be a common factor if it can divide two or more integers without producing a residue. Common factors are used in fraction operations to simplify fractions and carry out operations like addition, subtraction, multiplication, and division.

Finding a common denominator is necessary, for instance, when adding or subtracting fractions. A multiple of all the fractions' denominators is referred to as a common denominator. We can determine the shared characteristics of the denominators and utilise the lowest common multiple (LCM) as the common denominator to obtain a common denominator.

Given that, one-eighth foot long pieces can be cut from a 5/6 foot long piece of cardboard.

First, we need to convert 5/6 feet into eighths of a foot:

5/6 feet = (5/6) * 8 eighths = 40/48 eighths

Next, we need to divide 40/48 by 1/8 to find the number of one-eighth foot long pieces that can be cut:

(40/48) ÷ (1/8) = (40/48) * (8/1) = 320/48 = 6 2/3 pieces

Hence, Mr. Ferrell can cut 6 and 2/3 pieces that are one-eighth foot long from a 5/6 foot long piece of cardboard.

1. The table shows the Total Expenses y (in dollars) of the College or University for year 2020-2021 and 2021-2022. Mine it's 21,211
a) Write a function that represents the Total Expenses y (in dollars) of that College or University you would like to attend after t years.

b) Use the function to estimate the Total Expenses your first year of school. *This year (t) is not the same for everyone since there are 8th graders to 11th graders in the class.



c) Sketch a graph (by hand) to model your function.


d) Identify the y-intercept and asymptotes of the graph. Find the domain and range of your function. Then describe the end behavior of the function.

Answers

Answer:

a) We can use the given data to find the rate of change (slope) of the expenses over one year, and then use it to write the equation of a line in slope-intercept form:

Slope m = (Total Expenses in 2021-2022 - Total Expenses in 2020-2021) / 1 year

m = (23,500 - 21,211) / 1 = 2,289

Using the point-slope form of a line, we can write the equation as:

y - 21,211 = 2,289(t - t1), where t1 is the year 2020-2021.

Simplifying, we get:

y = 2,289t + 18,922

b) To estimate the Total Expenses for your first year of school, you need to know what year you will start. Let's say you will start in 2024-2025, which is 3 years from 2021-2022.

Then, plugging in t = 3 into the equation we just found, we get:

y = 2,289(3) + 18,922 = 23,789

So the estimated Total Expenses for your first year of school would be $23,789.

c) The graph of the function y = 2,289t + 18,922 is a straight line with a positive slope of 2,289. It passes through the point (0, 18,922) on the y-axis, and it will extend indefinitely in both directions.

d) The y-intercept of the graph is the point (0, 18,922), which represents the Total Expenses for the year 2020-2021. There are no vertical asymptotes, but the graph will approach a horizontal asymptote as t goes to infinity, since the expenses cannot increase indefinitely. The domain of the function is all real numbers, and the range is all values greater than or equal to 18,922. As t increases, the function increases without bound, so the end behavior is that the graph goes up to the right.

There are two coins in a bin. When one of them is flipped it lands on heads with probability 0.6 and when the other is flipped, it lands on heads with probability 0.3. One of these coins is to be chosen at random and then flipped. a) What is the probability that the coin lands on heads? b) The coin lands on heads. What is the probability that the chosen coin was the one that lands on heads with probability 0.6?

Answers

When one of the coin is flipped it lands on heads with probability 0.6 and when the other is flipped, it lands on heads with probability 0.3, then the probability that the coin lands on heads is 0.45 and the coin lands on heads but the probability that the chosen coin was the one that lands on heads with probability 0.6 is 0.67.

a) The probability of getting heads, we can use the law of total probability.

There are two coins, and each has a probability of landing on heads. So we can calculate the probability of getting heads by weighting each coin's probability by its probability of being chosen.

Therefore,

P(heads) = P(heads from coin 1) * P(choose coin 1) + P(heads from coin 2) * P(choose coin 2)

Plugging in the values, we have:

P(heads) = 0.6 * 0.5 + 0.3 * 0.5 = 0.45

Therefore, the probability of getting heads is 0.45.

b) The probability that the chosen coin was the one that lands on heads with probability 0.6, given that the coin lands on heads, we need to use Bayes' theorem. Specifically, we have:

P(choose coin 1 | heads) = P(heads from coin 1 | choose coin 1) * P(choose coin 1) / P(heads)

Plugging in the values, we have:

P(choose coin 1 | heads) = 0.6 * 0.5 / 0.45 = 0.67

Therefore, the probability that the chosen coin was the one that lands on heads with probability 0.6, given that the coin lands on heads, is 0.67.

The approximate probability that the mean credit card debt for a sample of 50 US households will exceed $7,500 is , based on a normal distribution with a mean of $7,115 and a standard deviation of $2,160.

What is the z-score formula?

The z-score formula is a statistical method used to calculate the standard deviation of a raw score or data point relative to the mean of the group of raw scores or data points. It is given as:

[tex]z = \frac{x - \mu}{\sigma}[/tex]

where z is the z-score, x is raw score, μ is the mean, and σ is the standard deviation.

The approximate probability can be calculated as follows:

First, find the standard error of the mean: [tex]SE = \frac{\sigma}{\sqrt{n}}[/tex]

[tex]SE = \frac{2,160}{\sqrt{50}}\\\\SE = 305.39[/tex]

Secondly, find the z-score: [tex]z = \frac{\overline{x} - \mu}{SE}[/tex]

[tex]z = \frac{7,500 - 7,115}{305.39}\\\\z = 1.263[/tex]

The probability that a z-score will be greater than 1.263 is 0.1038 from the standard normal table or calculator.

Therefore, the approximate probability is 0.1038 or 10.38%.

Step-by-step explanation:

To write 0.246 as a fraction in simplest form, we need to remove the decimal and reduce the fraction to its lowest terms.

Step 1: Write 0.246 as the fraction 246/1000.

(Note: We get the denominator 1000 by counting the number of decimal places after the 6 in 0.246.)

Step 2: Simplify the fraction by dividing both the numerator and denominator by the greatest common factor.

The greatest common factor (GCF) of 246 and 1000 is 2.

246/2 = 123

1000/2 = 500

Therefore, 0.246 written as a fraction in simplest form is 123/500.

There are 1200 students in a school if 780 of them are girls what is the percentage of boys in the school?

Answers

We divide the number of boys by the total number of students (1200) and multiply by 100. Percentage of boys = (420/1200) x 100% = 35%.

To find the percentage of boys in the school, we need to subtract the number of girls from the total number of students, then divide by the total number of students and multiply by 100 to get the percentage.

Number of boys = total number of students - number of girls

Number of boys = 1200 - 780

Number of boys = 420

Percentage of boys = (number of boys / total number of students) x 100

Percentage of boys = (420 / 1200) x 100

Percentage of boys = 35

Therefore, the percentage of boys in the school is 35%.

A 5x5x5 cube is formed by assembling 125 unit cubes. Nine unit squares are painted on each of the six faces of the cube according to the pattern shown. How many of the 125 unit cubes have no paint on them?

Answers

In a 5x5x5 cube, 125-unit cubes are formed by assembling. According to the pattern shown, nine-unit squares are painted on each of the six faces of the cube.  So the number of unit cubes that have no paint on them is 71.

     To calculate the total number of unit cubes, multiply the number of unit cubes in each dimension.

                  Thus, 5 × 5 × 5 = 125 cubic units.

      Since there are 6 faces to be painted, and each face has nine painted unit cubes, the total number of painted cubes is

                  6 × 9 = 54.

         Each painted cube has three faces painted since the cube has three faces of the same size.

          There are eight cubes on each of the edges that have three faces painted, so there are

                 8 × 12 = 96 of them that have three faces painted.

           There are 12 edge cubes in total, all of which have two painted faces, for a total of

                 12 × 2 = 24 cubes that have two painted faces.

            There are 6 center cubes in the cube, all of which have one painted face, for a total of 6 cubes with one painted face.

            Each painted cube contributes one face to the total. As a result, the number of unpainted cubes is

                 125 - 54 = 71.

       The number of unit cubes that have no paint on them is 71.
