The dot plot below shows how many customers purchased different numbers of shirts at a sale last weekend.
scoray [572]

Answer:

the answer is 1.16 shirts

Step-by-step explanation:

the mean absolute deviation is found by finding the average of the difference between each data point and the mean of the data.

1st...find the mean of the data by adding all the numbers according to the data plotted and dividing the by the numbers listed; which in this case is 10

1 +2+ 2+ 3+ 3+ 3+ 4+ 4+ 5+ 6 = 3.3

mean is 3.3

then find the difference between the mean and each data point

Data Point =                       1      2     2      3     3       3      4      4     5      6

Difference from mean = 2.3    1.3   1.3  0.3  0.3   0.3   0.7    0.7   1.7   2.7

Find the average of these differences by adding the (differences from Mean) by 10

<u>2.3  + 1.3  + 1.3  + 0.3  + 0.3  + 0.3  + 0.7  + 0.7 +  1.7 + 2.7</u>

                                             10

the mean absolute deviations is 1.16 shirts

A salesperson is paid a base salary of $1700 per month plus a 4.25% commission on sales. How much sales must he generate in orde
iren [92.7K]

Salesperson must generate a sales of $ 26280 in order to earn $2,816.90 per month in total compensation

<em><u>Solution:</u></em>

Given that,

A salesperson is paid a base salary of $1700 per month plus a 4.25% commission on sales

Therefore,

Total salary = 1700 + 4.25 % commission on sales

<em><u>How much sales must he generate in order to earn $2,816.90 per month in total compensation?</u></em>

Therefore, let us first subtract the basic salary

2816.90 - 1700 = 1116.9

We have to find the sales he must generate

Let "x" be the sales he must generate

4.25 % of x = 1116.9

Therefore,

4.25 \% \times x = 1116.9\\\\\frac{4.25}{100} \times x = 1116.9\\\\0.0425x = 1116.9\\\\x = \frac{1116.9}{0.0425}\\\\x = 26280

Thus he must generate a sales of $ 26280 in order to earn $2,816.90 per month in total compensation
