c = -6

a = -3/2

m = -24/5

Step-by-step explanation:

5(c + 2) = -20

5c + 10 = -20

5c = -20 - 10

5c = -30

<u>c = -6</u>

12a + 5 - 8a = -1

4a + 5 = -1

4a = -1 - 5

4a = -6

a = (-6)/4

<u>a = -3/2</u>

m - 3 - 6m = -27

-5m - 3 = -27 → (times -1)

5m + 3 = 27

5m = 27 - 3

5m = 24

<u>m = 24/5</u>

pochemuha

Answer:

Comprehensive deductible

Step-by-step explanation:

There is nothing called Premium deductible rather deductible determines how higher of lower a premium on a subject matter of insurance can be. Deductible is the amount with the insured have to bear at loss and any excess above the loss will be compensated by the insurance company.

Comprehensive deductible is the application to only to comprehensive insurance which was what Chad had on his motor vehicle. Comprehensive insurance covers majority of peril that happens to the insured vehicle. Therefore, comprehensive deductible is the deductible Chad has to bear himself before the insurance company take other losses upon theirself..

If he had $500 deductible on his car and total repair cost $700, then he will bear the $500 while the insurance company is entitled to pay only $200 as per policy statement.

RSB [31]

The question is to find an expression for the expenses

<u>Answer:</u>

E (x) =n + 5

<u>Explanation:</u>

The profit is defined as the difference between the revenue and the expenses.

<u>This means that:</u>

profit = revenue - expenses

<u>Now, we rearrange the equation to solve for expenses:</u>

expenses = revenue - profit

<u>From the given, we know that:</u>

expression for revenue is 18n

expression for profit is 17n - 5

<u>Substitute in the equation to get expression for expenses as follows:</u>

E (x) = 18n - (17n - 5)

E (x) = 18n - 17n + 5

E (x) = n + 5

Hope this helps :)

The dot plot represents a sampling of ACT scores: dot plot titled ACT Scores with Score on the x axis and Number of Students on

Fantom [35]

Step-by-step explanation:

Hi,

To draw a box plot, you require certain points on the graph calculated.

Quartile 1
Quartile 2 or Median
Quartile 3

As per the information provided, your data looks like this:

<em>(Each dot in the dot plot shows the frequency of the score)</em>

18, 19, 19, 19, 21, 21, 21, 21, 22, 22, 22, 22, 23, 23, 23, 24, 24, 25.

Using the data, we first calculate the median.

Median of any data set is the most central value. Since there are 18 values in this data set, we consider the two most central values, which are the 9th and 10th values.

The 9th value of the data corresponds to 22.

The 10th value of the data corresponds to 22.

Hence the median is 22.

<em>(Had these two values been different, we would have simply add them and divided the sum by 2 to find the median.)</em>

<em />

Now we find Quartile 1, which is one-fourth value of the data.

$Q_{1} = \frac{n}{4} = \frac{18}{4} = 4.5$

4.5th value is Q1, which lies between 4th and 5th value.

4th value of the data set corresponds to 19.

5th value of the data set corresponds to 21.

We add them both and divide the sum by 2.

$\frac{19+21}{2} = 20$

Hence the first quartile is 20.

Now we find Quartile 3, which is three-fourth value of the data.

$Q_{3} = \frac{3n}{4} = \frac{18*3}{4} = 13.5$

13.5th value is Q3, which lies between 13th and 14th value.

13th value of the data set corresponds to 23.

14th value of the data set corresponds to 23.

Hence the third quartile is 23.

To plot the box, the top line of the box is at Q3, central line at Median and lower end of the box at Q1.

The two whiskers of the plot, upper is at the highest point: 25 and lower is at the lowest point: 18.

Your plot should look like this:
