A discount store marks up the merchandise it sells by 55% if the whole sale price of a particular item is $25 what should the retail price be set at

Answers

Answer 1
We're setting a price by increasing the value: 100% of the wholesale value, plus the markup (55%)
100+55 = 155% of the original price - 1.55 as a decimal number
25 x 1.55 = $38.75

The volume of a cube depends on the length of its sides. This can be written in function notation as v(s). What is the best interpretation of v(2) = 8?

Answers

What is the best interpretation of v(2) = 8?


v(s) = a³ , a being the side of the cube and v, the volume. Moreover 
the sub s in v(s) gives the length of the side "a":

v(s) = a³
v(2) = 8 → v(2) = 2³  → v(2) = 8 

If you have 256 data points, how many classes (bins) would sturges' rule suggest

Answers

Since Sturge's Rule states that the optimal number of bins is equal to the 1 plus 3.3 log(n), where n is the number of data points, the estimated solution (since you can only have whole bins) is to provide 6 bins, each storing 42 to 43 data points.

Final answer:

Sturges' rule suggests using 9 classes or bins for 256 data points.

Explanation:

Sturges' rule is a method for determining the number of classes or bins required for a histogram. According to Sturges' rule, the formula to calculate the number of classes is:

K = 1 + log2(n)

Where K is the number of classes and n is the number of data points. In this case, since you have 256 data points, the number of classes suggested by Sturges' rule would be:

K = 1 + log2(256)

K = 1 + log2(28)

K = 1 + 8

K = 9

Therefore, Sturges' rule would suggest using 9 classes or bins for the histogram.

Find y'' by implicit differentiation. 4x3 + 5y3 = 2

Answers

The value of implicit differentiation of y"  of the 4x³ + 5y³ = 2 is [tex]30y \times \frac{dy}{dx} + 15y^2 \times \frac{d^2y}{dx^2} = 0\\[/tex].

To find y'', or the second derivative of y, by implicit differentiation, we'll differentiate both sides of the equation with respect to x, treating y as a function of x.

Step - 1:

Start by differentiating each term with respect to x using the chain rule:

Differentiating 4x³ with respect to x gives 12x².Differentiating 5y³ with respect to x requires the chain rule. We get 15y²(dy/dx).

Since we're differentiating with respect to x, we need to multiply dy/dx by y' to indicate the derivative of y with respect to x.

Step - 2:

The right-hand side of the equation, 2, has a derivative of 0 since it is a constant.

Putting it all together, we have the equation:

[tex]12x^2 + 15y^2 \times \frac{dy}{dx} = 0.[/tex]

Now, to find y'', we differentiate this equation with respect to x, treating dy/dx as a function of x.

Differentiating 12x² with respect to x gives 24x.Differentiating 15y² × dy/dx with respect to x requires the product rule. We get [tex]30y \times \frac{dy}{dx} + 15y^2 \times \frac{d^2y}{dx^2}[/tex].

Step - 3:

The right-hand side of the equation, 0, has a derivative of 0 since it is a constant.

Putting it all together, we have the equation:

[tex]30y \times \frac{dy}{dx} + 15y^2 \times \frac{d^2y}{dx^2} = 0\\[/tex]

Explanation:

To find the second derivative y'' by implicit differentiation for the equation 4x^3 + 5y^3 = 2, you follow these steps:

Differentiate both sides of the equation with respect to x to find the first derivative (y').Apply the chain rule to differentiate y terms, remembering to multiply by y' (dy/dx) because you are differentiating with respect to x.The differentiation of 4x^3 yields 12x^2, and the differentiation of 5y^3 using the chain rule gives you 15y^2*y'.You then set the derivative equal to 0, because the differential of 2 with respect to x is 0.To find the second derivative (y''), differentiate your expression for y' with respect to x again, applying the chain rule and product rule as necessary.

This process will provide you with the value of y''.

How to find mean and standard deviation for binomial distribution?

Answers

Final answer:

To calculate mean and standard deviation for a binomial distribution, use the formulas μ = np and σ = √npq. Ensure both np and nq are greater than five to use the normal approximation.

Explanation:

To find the mean (μ) and standard deviation (σ) for a binomial distribution, you use the formulas μ = np and σ = √npq respectively. Here, 'n' represents the number of trials, 'p' is the probability of success on a single trial, and 'q' is the probability of failure on a single trial, which is calculated as q=1-p.

If you want to determine whether you can use the normal approximation to the binomial, it is essential to ensure that both np and nq are greater than five. This is because the normal approximation is most accurate when the binomial distribution is symmetrical, which typically occurs when both np and nq exceed five.

Answers

In 2156 ways the selection be made so that at least one of each color is drawn?

The question is asking for the number of ways to select balls from a bowl containing 8 red balls and 9 blue balls if 4 balls are drawn and at least one of each color is drawn.

To solve this, we must consider the different combinations of red and blue balls that meet the requirement.

Calculate the total possible outcomes: 17C4 = 2380

Calculate the outcomes where all balls of one color are drawn: 9C4 + 8C4 = 224

Subtract the outcomes where only one color is drawn from the total: 2380 - 224 = 2156 ways

Jenna hikes 2 miles in 1 hour, as she covers 1/2 mile in each 1/4 hour and there are four 1/4 hours in a full hour.

Jenna hikes 1/2 mile every 1/4 hour. To determine how far she hikes in 1 hour, we need to calculate the distance she can cover in four such intervals since 1 hour is composed of four 1/4 hours.

A sampling distribution is constructed based on a sample size of 9. if the sampling distribution has a mean of 500 and a standard error of 15, what is the standard deviation of the original comparison population

Answers

This is one that most people can figure out.
Final answer:

The standard deviation of the original comparison population is 45.

Explanation:

The standard deviation of the original comparison population can be calculated using the formula:

Standard deviation of the sampling distribution = standard error * sqrt(sample size)

Given that the standard error of the sampling distribution is 15 and the sample size is 9, we can substitute these values into the formula:

The standard deviation of the original comparison population can be determined by using the relationship between the standard deviation, standard error, and sample size in a sampling distribution. The formula is:

[tex]\[ \text{Standard deviation of the original comparison population} = \text{Standard error} \times \sqrt{\text{Sample size}} \][/tex]

Given a standard error of 15 and a sample size of 9, substitute these values into the formula:

\[ \text{Standard deviation of the original comparison population} =[tex]15 \times \sqrt{9} = 15 \times 3 = 45 \][/tex]

Therefore, the standard deviation of the original comparison population is 45.

Standard deviation of the original comparison population = 15 * sqrt(9) = 15 * 3 = 45

Therefore, the standard deviation of the original comparison population is 45.
