As per the given percentage, Sandesh should aim to sell his apples at 250rs per kg in order to gain 20% profit.

Let C be the cost of the 15kgs of apples. Sandesh gained 12%, so his profit is 0.12C. We know that Sandesh sold the apples for 2100rs, so we can write an equation:

C + 0.12C = 2100

Simplifying this equation gives:

1.12C = 2100

Dividing both sides by 1.12 gives:

C = 1875

So Sandesh's cost for 15kgs of apples was 1875rs.

Now, we need to find the selling price per kg of apples that Sandesh should aim for in order to gain 20% profit. Let P be the selling price per kg of apples.

Since Sandesh wants to gain 20% profit, his selling price per kg of apples needs to be his cost plus 20% of his cost, or 1.2 times his cost.

So we can write another equation:

1.2C = 15P

Substituting the value of C we found earlier, we get:

1.2(1875) = 15P

Simplifying gives:

P = 250

This selection process is referred to as "systematic sampling"

Systematic sampling is the sampling method where samples are selected based on a systematic interval in a population. It is a type of probability sampling, where every kth element in the population is selected as a sample, where k is a constant value.

The interval k is calculated by dividing the population size N by the sample size n; hence, k = N/n. In this case, the sample size is 100, and the population size is 100,000, so the interval is k = 1000. The selection process involved in this question is an example of systematic sampling because the selection of the 100 sales invoices is based on a systematic interval of 1000.

The probability that exactly 3 homes will be sold tomorrow is A) 0.1809.

To solve this problem, we can use the Poisson distribution formula, which is:

P(x; μ) = (e^-μ) (μ^x) / x!

where P(x; μ) is the probability of x events happening in a given time period, μ is the mean number of events in that time period, e is the mathematical constant approximately equal to 2.71828, and x! is the factorial of x.

In this case, we want to find the probability of exactly 3 homes being sold tomorrow, given that the average number of homes sold is 2 per day. So, we plug in μ = 2 and x = 3 into the formula:

P(3; 2) = (e^-2) (2^3) / 3! = 0.1809

Therefore, the probability that exactly 3 homes will be sold tomorrow is 0.1809 or approximately 18.09%. This means that out of every 100 days, we can expect that around 18 of those days will have exactly 3 homes sold by Acme Realty Company.

Step-by-step explanation:

Jen has 54 pages left to read to meet her assignment requirement.

The inequality that represents this situation is p ≥ 85 - 31

To find how many pages Jen has left to read, we can subtract the number of pages she has already read from the minimum number of pages she needs to read.

The minimum number of pages Jen needs to read is 85, and she has already read 31 pages. So, the number of pages she has left to read, p, can be found by:

p = 85 - 31

p = 54

Therefore, Jen has 54 pages left to read.

To represent this situation with an inequality, we can use:

p ≥ 85 - 31

This inequality states that the number of pages Jen still needs to read, p, must be greater than or equal to the difference between the minimum number of pages she needs to read (85) and the number of pages she has already read (31).

Solving for p:

p ≥ 85 - 31

p ≥ 54

This means that Jen must read at least 54 more pages to meet her assignment requirement.

So the correct answer is option A) m=5, LO=14, NO-12 for the indicated variables and measures for the figure below.

A triangle is a closed two-dimensional geometric figure with three straight sides and three angles. It is one of the basic shapes in geometry and can be classified based on the length of its sides and the measures of its angles. The sum of the interior angles of a triangle is always 180 degrees, and the length of each side is less than the sum of the lengths of the other two sides. Triangles have many properties and are used in various mathematical and real-world applications, including trigonometry, geometry, and engineering.

Here,

Since all the angles are equal, we can set up the following proportion:

LO/NO = 7/2

Multiplying both sides by NO, we get:

LO = (7/2)NO

We can also use the fact that the angles are equal to set up an equation involving m:

m + (1/2)LO + (1/2)NO = 180

Substituting LO = (7/2)NO, we get:

m + (7/4)NO = 180

Now we can substitute the given values for LO and NO:

m + (7/4)(14) = 180

m + 49 = 180

m = 131

Therefore, the answer is: m = 131, LO = 49, NO = 14

The z value when making 98% confidence interval for p will be 2.33.

When making a confidence interval for a proportion, we use the standard normal distribution, and the value of z depends on the level of confidence we want to achieve.

In this case, we want to make a 98% confidence interval, which means that we want to be 98% confident that the true proportion falls within our interval.

To determine the value of z, we can use a z-table or a calculator. The z-value corresponding to a 98% confidence level is 2.33. Therefore, we use 2.33 as our value of z when making a 98% confidence interval for p.

It is not impossible to make a 98% confidence interval, and the value of z is not 2.88. The z-value of 2.88 corresponds to a much higher confidence level of approximately 99.5%.

Yes, it can be proved that the driver had been speeding.

The driver had been speeding since the distance traveled during the 19-second skid is greater than the distance the car would have traveled at 60 mph in the same time. This implies that the driver was traveling at a higher speed than the speed limit before braking.

To explain further, we can calculate the distance a car traveling at 60 mph would cover in 19 seconds, which is 1,672 feet (60 mph = 88 fps, 19 seconds x 88 fps = 1,672 feet). However, the car in question skidded for 1700 feet before coming to a complete stop, which is greater than the distance it would have traveled at 60 mph in the same time.

The secant tangent angle is the angle formed by a tangent and a secant that intersect outside of a circle. The measure of the secant tangent angle can be found using the following formula:

θ = 1/2 (arc EB - arc BD)

where arc EB and arc BD are the measures of the arcs intercepted by the secant and tangent, respectively.

From the question,

θ = m∠NXK = 4x + 6

arc EB = 8x - 13

arc BD = 70° + (6x - 1) = 69 + 6x

4x + 6 = 1/2[69 + 6x - (8x - 13)]

Answer:

If the store marks up the price of the diving board by 45%, the selling price will be 100% + 45% = 145% of the cost price.

Let's calculate the selling price:

Selling price = Cost price + Mark-up

Mark-up = Selling price - Cost price

Mark-up = (145% of cost price) - cost price

Mark-up = 0.45 * cost price

We know that the store paid $261 for the diving board, so:

Mark-up = 0.45 * $261 = $117.45

Therefore, the amount of the mark-up is $117.45.

The solution set of the equation x/3 = 8/(x + 2) when calculated is x = -6 or x = 4

Given the following equation

x/3 = 8/(x + 2)

Cross multiply

x(x + 2) = 24

To find the solution set of x(x + 2) = 24, we need to solve for x by simplifying the left-hand side of the equation and then factoring it.

x(x + 2) = 24

Expanding the left-hand side, we get:

x² + 2x = 24

Subtracting 24 from both sides, we get:

x² + 2x - 24 = 0

Now we can factor the quadratic expression on the left-hand side:

(x + 6)(x - 4) = 0

Using the zero product property, we know that the product of two factors is zero if and only if at least one of the factors is zero.

Therefore, we can set each factor equal to zero and solve for x:

x + 6 = 0 or x - 4 = 0

Solving for x, we get:

x = -6 or x = 4

So, the solution set is { -6, 4 }.

Answer:

When the determinant of a matrix is almost 0, it means that the matrix is close to being singular, which means that its inverse does not exist or is very close to not existing. This has important implications for the solution of systems of linear equations represented by the matrix.

Specifically, if the determinant of a matrix is almost 0, then the matrix is almost singular, which means that its columns are almost linearly dependent. This, in turn, means that the system of equations represented by the matrix has almost linearly dependent equations, which can lead to multiple solutions or no solutions at all.

In terms of the sensitivity of the solution to changes in the constants of the system, a small change in the constants can lead to a large change in the solution when the determinant of the matrix is almost 0. This is because the inverse of the matrix is very sensitive to changes in its entries when the determinant is almost 0.

For example, consider a system of linear equations represented by a matrix A with determinant very close to 0, and let b be the vector of constants on the right-hand side of the equations. Then, the solution to the system can be approximated by the product of the inverse of A (if it exists) and b, that is:

x = A^(-1) b

However, if A is almost singular, then its inverse is very sensitive to changes in its entries, and a small change in b can lead to a large change in x. This can make the solution to the system unreliable and unstable, and can be a source of numerical errors in computations.

Step-by-step explanation:

Suppose that s is the position function of an object, given as s(t) = 2t - 7. We compute the instantaneous velocity of the object at t = 6 as follows. Use exact values. First we compute and simplify (6 + h). s(6 + h) = 2(6 + h) - 7 = 12 + 2h - 7 = 2h + 5Then we compute and simplify the average velocity of the object between t = 6 and t = 6 + h.8(6+h) - s(6) h = 8(6 + h) - (2(6) - 7) h= 8h + 56

Then, to rationalize the numerator in the average velocity. (If it applies, simplify again.)$(6 + h) - $(6) h(h(h) + 56)/(h(h)) = (8h + 56)/h The instantaneous velocity of the object att = 6 is the limit of the average velocity as h approaches zero.s(6 + h) – $(6) v(6) lim h -0s(6 + h) – s(6) v(6) lim h -0Using the above calculation, we get:s(6 + h) – s(6) / h lim h -0s(6 + h) = 2(6 + h) - 7 = 2h + 5So,s(6 + h) – s(6) / h lim h -0(2h + 5 - (2(6) - 7)) / h= (2h + 5 - 5) / h = (2h / h) = 2

Newton's Law of Cooling states that the rate of change of the temperature of an object is proportional to the difference between its own temperature and the ambient temperature.

The law of cooling is given as

[tex]T(t) = T_m + (T_0 - T_m)e^{-kt}[/tex]

whereT(t) is the temperature of the object at time t.

[tex]T_0[/tex] is the temperature of the object initially.

[tex]T_m[/tex] is the temperature of the medium in which the object is kept.

k is a positive constant.

The formula is used to solve for the time it will take the baked potato to reach 90 degrees Celsius.

This is given as:

[tex]T(t) = T_m + (T_0 - T_m)e^{-kt}[/tex]

[tex]90 = 20 + (37 - 20)e^{-kt}[/tex]

Let's start by solving for k.

[tex]37 = 20 + (37 - 20)e^{-k(10)}[/tex]

[tex]17 = 17e^{-10k}[/tex]

[tex]ln(1) = -10k[/tex]

[tex]k = 0[/tex]

Substituting k = 0 in the equation,

[tex]\frac{70}{17} = e^{(0(t))}[/tex]

Taking the natural log of both sides,

[tex]ln\frac{70}{17}  = lne^{0(t)}[/tex]

$$\left(\dfrac{-u}{4}\right)=\dfrac{1}{\sqrt\pi}\left(\dfrac{M}{2RT}\right)^{\frac{3}{2}}\int_{0}^{\infty}v^{3}e^{\frac{-Mv^{2}}{2RT}}dv$$Let's solve the integral first. We'll use the integral rule:

$$\int xe^{ax^{2}}dx=\dfrac{1}{2a}e^{ax^{2}}+C$$

So, the integral from the given formula can be re-written as:

$$\begin{aligned}&\int_{0}^{\infty}v^{3}e^{\frac{-Mv^{2}}{2RT}}dv \\ &\quad =-\dfrac{2RT}{M}\int_{0}^{\infty}\left(-\dfrac{Mv^{2}}{2RT}\right)\cdot v\cdot e^{\frac{-Mv^{2}}{2RT}}dv \\ &\quad =-\dfrac{2RT}{M}\int_{0}^{\infty}vde^{\frac{-Mv^{2}}{2RT}} \\ &\quad =-\dfrac{2RT}{M}\left[ve^{\frac{-Mv^{2}}{2RT}}\right]_{0}^{\infty} \\ &\quad =\dfrac{2RT}{M}\cdot 0+ \dfrac{2RT}{M}\cdot \infty \\ &\quad =\infty\end{aligned}$$This means that the integral of the formula is infinity. Therefore, to make the equation equal to the given answer, the given formula for the average speed of molecules in an ideal gas must be equated with the most probable speed. The most probable speed of the gas is the speed at which the likelihood of finding molecules is the highest. It is given by the following formula:

$$v_{mp}=\sqrt{\dfrac{2RT}{M}}$$Therefore,

$$v_{mp}=\sqrt{\dfrac{2RT}{M}}=\sqrt{\dfrac{8RT}{4M}}=\sqrt{\dfrac{8RT}{\pi M}}$$Hence, we have shown that v= √8 RT/ πM.

In order to expect a return on $400 from across all policies of a similar nature, the insurance firm should charge the policy for about $501.88.

Return[expr] leaves control structures that are present during a function's definition and returns the value expression for the entire function. Even if it comes inside other functions, yield takes effect as quickly as it is evaluated. Functions like Scan can use Return inside of them.

Since p is the chance that the 28-year-old woman survives the year and is given as 0.99962, we can enter this number into the equation for n as follows: n = 400(0.99962)/500,400 n 0.799

In light of this, the insurance provider should impose a premium of: Premium = 400/n

$501.88 is the premium ($Premium = 400/0.799)
