Answer: Therefore, the commission rate is 18%.

Step-by-step explanation: To find the commission rate, we divide the commission earned by the total sales and then express it as a percentage.

Commission Rate = (Commission Earned / Total Sales) * 100

In this case, the commission earned is $540 and the total sales are $3000. Plugging these values into the formula, we have:

Commission Rate = (540 / 3000) * 100

Calculating this expression, we get:

Commission Rate = 0.18 * 100

Step-by-step explanation:

7 + 4 = 11 --> 4 = 2²

11 - 9 = 2 --> 9 = 3²

2 + 16 = 18 --> 16 = 4²

18 - 25 = -7 --> 25 = 5²

Notice that the pattern is adding and then subtracting the next square number up. Therefore, the next number in the sequence would be -7 + 36 = 29 since 6²=36.

There will be 12 slices of pizza left over, which can be expressed as 3/2 or 1 1/2 slices in fraction form.

To find out how much pizza will be left over, we need to calculate the total number of slices available and subtract the number of slices consumed by the players.

Given that there are six pizzas and each pizza has eight slices, the total number of slices available is 6 pizzas * 8 slices/pizza = 48 slices.

Since there are 36 players on the team, and each player has one slice, the total number of slices consumed is 36 slices.

To determine the remaining slices, we subtract the consumed slices from the total available slices: 48 slices - 36 slices = 12 slices.

Therefore, there will be 12 slices of pizza left over.

To express this as a fraction, we can write it as 12/1, which simplifies to 12. This means there will be 12 whole slices of pizza left over.

If you would like to express it as a fraction in its simplest form, you can write it as 12/8. By dividing both the numerator and denominator by their greatest common divisor, which is 4, we get 3/2. So, in fraction form, there will be 3/2 or 1 1/2 slices of pizza left over.

The simplified form of the expression (2^-6)(5)(2^3*5)^2 is 25/2.

To simplify the expression (2^-6)(5)(2^3*5)^2, let's break it down step by step:

First, we can simplify 2^-6. A negative exponent indicates taking the reciprocal of the base raised to the positive exponent. In this case, 2^-6 can be written as 1/(2^6).

Next, we can evaluate (2^35)^2. Inside the parentheses, we have 2^35. This can be simplified to 8*5, which equals 40. Then, we raise 40 to the power of 2, resulting in 40^2.

Now, let's put everything together:

(2^-6)(5)(2^3*5)^2 = (1/(2^6))(5)(40^2)

To simplify further, we can simplify the powers of 2 and 40:

2^6 = 64

40^2 = 1600

Substituting these values back into the expression:

(1/64)(5)(1600) = (5/64)(1600)

We can further simplify by multiplying 5 and 1600:

(5/64)(1600) = 800/64

Finally, we can simplify 800/64 by dividing both numerator and denominator by 8:

800/64 = 100/8 = 25/2

Therefore, the simplified form of the expression (2^-6)(5)(2^3*5)^2 is 25/2.

Yes, the additional education costing $36,000 will pay for itself in less than 2 years based on the increased earning potential.

To determine whether the additional education costing $36,000 will pay for itself, we need to consider the time it takes to recover the investment through the increased earning potential.

The additional yearly earning potential is the difference between the post-education income ($39,746) and the pre-education income ($21,484), which is $18,262.

To calculate the payback period, we divide the cost of education ($36,000) by the annual increase in earning potential ($18,262).

Payback Period = Cost of Education / Annual Increase in Earning Potential

Payback Period = $36,000 / $18,262

The payback period is approximately 1.97 years, meaning that it would take approximately 1.97 years to recover the cost of education through the increased earning potential.

If the time required to recover the cost is less than the time in which the increased earning potential will be realized, then the additional education would be considered to have paid for itself.

In this case, since the payback period is less than 2 years and the increased earning potential will continue for subsequent years, it can be concluded that the additional education costing $36,000 will pay for itself over time.

The value x in the secant line using the Intersecting theorem is 4.

Intersecting secants theorem states that " If two secant line segments are drawn to a circle from an exterior point, then the product of the measures of one of secant line segment and its external secant line segment is the same or equal to the product of the measures of the other secant line segment and its external line secant segment.

From the figure:

First sectant line segment = ( x - 1 ) + 5

External line segment of the first secant line = 5

Second sectant line segment = ( x + 2 ) + 4

External line segment of the second secant line = 4

Using the Intersecting secants theorem:

5( ( x - 1 ) + 5 ) = 4( ( x + 2 ) + 4 )

Solve for x:

5( x - 1 + 5 ) = 4( x + 2 + 4 )

5( x + 4 ) = 4( x + 6 )

5x + 20 = 4x + 24

Answer:

Therefore, the vertices of the image L'M'N' after rotating the triangle 180° counterclockwise about the origin are:

L'(1, -4), M'(1, 0), N'(3, -4)

Step-by-step explanation:

To determine the vertices of the image L'M'N' after rotating the triangle LMN 180° counterclockwise about the origin, we can apply the rotation transformation to each vertex.

The rotation of a point (x, y) by 180° counterclockwise about the origin can be obtained by switching the signs of both coordinates. So, if the original vertex is (x, y), the rotated vertex will be (-x, -y).

Applying this to each vertex:

L'(-x, -y) = L'(-(-1), -(4)) = L'(1, -4)

M'(-x, -y) = M'(-(-1), -(0)) = M'(1, 0)

N'(-x, -y) = N'(-(-3), -(4)) = N'(3, -4)

Therefore, the vertices of the image L'M'N' after rotating the triangle 180° counterclockwise about the origin are:

L'(1, -4), M'(1, 0), N'(3, -4)

All the exam scores are taken from the statistics classes at a community college, and the mean of all these scores is calculated. Since the community college is the population under consideration, the mean of the test scores is a population mean.

The mean score is referred to as the arithmetic average or simply average of the scores. It is a measure of central tendency that describes the typical score in a dataset.Population mean refers to the average of all the scores in a population. A population refers to the whole group of people, events, or things from which a sample is drawn. Therefore, the population mean of the test scores is calculated by summing up all the scores and dividing by the total number of scores.

In contrast, a sample mean refers to the average of all the scores in a sample. A sample is a subset of a population used to represent the population's characteristics. The sample mean is used to make inferences about the population mean. In statistics, the goal is often to estimate the population mean using the sample mean. This process is called point estimation.

A sample mean is used to estimate a population mean using statistical inference methods.The mean score is a useful measure because it provides a summary of the scores' central tendency. It represents the typical score in a dataset and is useful for making comparisons between different groups of scores. The mean is sensitive to outliers, so it is important to look at the spread of scores in a dataset to determine whether the mean is a good measure of central tendency.
