The profit margins (return on sales) for each division are approximately :Division A = 10.85%,Division B = 9.11% and The calculations for the year would be:Net Income = $85,428,Return on Assets = 18.9%.

To compute the profit margins (return on sales) for each division, we divide the profit by the sales and multiply by 100 to express the result as a percentage.

For Division A:

Profit Margin = (Profit / Sales) * 100

Profit Margin = ($230,000 / $2,120,000) * 100

Profit Margin ≈ 10.85%

For Division B:

Profit Margin = (Profit / Sales) * 100

Profit Margin = ($34,700 / $381,000) * 100

Profit Margin ≈ 9.11%

To calculate the net income and return on assets for Polly Esther Dress Shops Inc., we use the given information.

Net Income = Profit Margin * Sales

Net Income = 7% * $1,220,400

Net Income = $85,428

Return on Assets = Profit Margin * Asset Turnover

Return on Assets = 7% * 2.7

Return on Assets = 18.9%

Using synthetic division to divide x^3 + 8x^2 + 16x + 9 by x + 3 The quotient is x^2 + 5x - 29 and The remainder is: 6

To use synthetic division, we first set up the problem like this:

-3 | 1   8   16   9
   |______ -3  -45 -123
    1   5   -29 -114

The numbers on the top row are the coefficients of the polynomial (with any missing terms represented by a 0 coefficient), and the number on the left is the divisor we're dividing by (in this case, x + 3 written as -3). The first step is to bring down the first coefficient, which is 1. Then we multiply -3 by 1 to get -3, and write that below the next coefficient (8). We add 8 and -3 to get 5, and write that below the line. Then we multiply -3 by 5 to get -15, and write that below the next coefficient (16). We add 16 and -15 to get 1, and write that below the line. Finally, we multiply -3 by 1 to get -3, and add that to 9 to get 6.

The last number on the bottom row, 6, is the remainder. The other numbers on the bottom row, 1 5 -29, are the coefficients of the quotient. So the answer to the question is:  x^2 + 5x - 29 and 6.

The rate of the car is 55 miles per hour.

Let's break down the information given:

- The first car left the house at 10 am and traveled north.

- The second car left the house two hours later, which means it departed at 12 pm, and traveled south.

- Both cars traveled at the same rate.

- At 4 pm, the cars were 550 miles apart.

To solve for the rate of each car, we need to determine the total time each car traveled.

For the first car:

It traveled from 10 am to 4 pm, which is a total of 6 hours.

For the second car:

It traveled from 12 pm to 4 pm, which is a total of 4 hours.

Now, let's calculate the rate of each car using the formula: Rate = Distance / Time.

Let's assume the rate for both cars is represented by "r".

For the first car:

Distance = r * 6 hours.

For the second car:

Distance = r * 4 hours.

The sum of the distances traveled by both cars is equal to the total distance between them:

(r * 6) + (r * 4) = 550 miles.

Simplifying the equation:

10r = 550.

Dividing both sides by 10:

r = 55.

Therefore, the rate of each car is 55 miles per hour.

The price of fake teeth is $4 and the price of fake spiders is $1.50.

Two equations can be derived from this question:

5x + 10y = 35 equation 1

x = 4y - 2 equation 2

Where:

x = false teeth

y = fake spiders.

In order to determine the value of y, substitute for x in equation 1:

5(4y -2) + 10y = 35

20y - 10 + 10y = 35

Add similar terms

30y - 10 = 35

Combine similar terms

30y = 45

y = 45 / 30

y = $1.50

 The greatest common factor is the biggest number that divides evenly into each one of the numbers without a remainder...the only thing that's different about our situation is that we have variables in addition to regular number (but the same logic applies...we need to find the biggest variable that goes into k^4 , k^3 , and k^2 ).

The biggest number that goes into 15, 35 and 20 is the number 5. The biggest variable that goes into k^4 , k^3 , and k^2 is k^2

Combining the number and the variable, we get that the greatest common monomial factor is 5k^2

Since area is length x width, and we just figured out that width is 5k2 , all we have to do to find length is divide 15k4+35k3+20k2 by 5k2 , and we get that the length is 3k^2+7k+4

So the width is 5k^2 and the length is 3k2+7k+4

Since none of the 13 classmates had been given math homework between the original survey and Kelly's second survey, the sum of the values in the second data set is the same as the sum of the values in the original data set. Therefore, the change in the means can be determined without calculating the mean of either data set by considering the number of data points in each set.

Since both data sets have the same number of data points, the change in the means will be zero. This is because the mean is calculated by dividing the sum of the values by the number of data points, and since the sum of the values is the same in both data sets, the means will also be the same.

In other words, the change in the mean is calculated as follows:

Change in mean = Mean of second data set - Mean of first data set

Since none of the values in the second data set have changed, the mean of the second data set is the same as the mean of the first data set. Therefore, the change in the mean is:

Change in mean = Mean of second data set - Mean of first data set

= Mean of first data set - Mean of first data set

= 0

Thus, the change in the means between Kelly's original survey and her second survey is zero.

A graph is a visual representation of data or mathematical relationships. In mathematics, a graph typically consists of two axes, usually labeled x and y, that intersect at the origin (0,0).

To graph the equation 12x - y = 2, we need to rewrite it in slope-intercept form, y = mx + b, where m is the slope and b is the y-intercept.

First, we'll isolate y by subtracting 12x from both sides:

-12x + 12x - y = 2 - 12x

-y = -12x + 2

Now, we'll divide both sides by -1 to get y by itself:

y = 12x - 2

So the slope-intercept form of the equation is y = 12x - 2, which means the slope is 12 and the y-intercept is -2.

To graph this equation, we can plot the y-intercept at (0, -2), and then use the slope to find additional points. Since the slope is positive, we can move up 12 units and right 1 unit to find another point on the line. Connecting these points gives us the graph of the equation.

Here's a rough sketch of the graph:

The solution to the given differential equation is: x⁷ cos y = y + C

where C is the constant of integration

To solve the given differential equation:

\(\[7x^6\cos y dx - dy = 0\]\)

We can separate the variables and integrate both sides.

Separating variables, we can write the equation as:

\(\[7x^6\cos y dx = dy\]\)

Now, we can integrate both sides with respect to their respective variables:

\(\[\int 7x^6\cos y dx = \int dy\]\)

Integrating the left side:

\(\[\int 7x^6\cos y dx = 7 \int x^6 \cos y dx\]\)

To integrate \(\(x^6 \cos y\)\)with respect to x, we can use integration by parts.

Let's take u = x⁶ and \(\(dv = \cos y dx\)\).

Differentiating u with respect to \(\(x\) gives \(du = 6x^5 dx\).\)

Integrating dv with respect to x gives \(\(v = \int \cos y dx = \cos y \cdot x\).\)

Applying the integration by parts formula:

\(\[\int x^6 \cos y dx = u \cdot v - \int v \cdot du\]\)

Substituting the values:

\(\[\int x^6 \cos y dx = x^6 \cdot \cos y \cdot x - \int (\cos y \cdot x) \cdot (6x^5 dx)\]\)

Simplifying:

\(\[\int x^6 \cos y dx = x^7 \cos y - 6 \int x^6 \cos y dx\]\)

Moving the integral term to the left side:

\(\[7 \int x^6 \cos y dx = x^7 \cos y\]\)

Dividing both sides by 7:

\(\[\int x^6 \cos y dx = \frac{x^7 \cos y}{7}\]\)

Now, substituting this result back into our original equation:

\(\[7 \int x^6 \cos y dx = dy\]\)

\(\[\frac{7x^7 \cos y}{7} = dy\)

Simplifying:

x⁷ cos y = dy

Finally, the solution to the given differential equation is:

x⁷ cos y = y + C

where C is the constant of integration.

The null hypothesis is H0: μ ≤ 950 and the alternative hypothesis is H1: μ > 950.

The null hypothesis (H0) is the statement that we want to test and usually represents the status quo or the default assumption. In this study, the null hypothesis is that the average number of sales made by a sales associate per year is less than or equal to 950 sales. The alternative hypothesis (H1) is the statement that contradicts the null hypothesis and represents the researcher's claim or theory. In this case, the alternative hypothesis is that the average number of sales made by a sales associate per year is greater than 950 sales. To test this claim, the sales associate collects a sample of 39 sales associates and calculates the sample mean, which is 990 sales, and the population standard deviation, which is known to be 85 sales. Based on this sample, the sales associate can conduct a one-tailed hypothesis test at the 2.5% significance level to determine whether there is enough evidence to reject the null hypothesis and support the alternative hypothesis.
