Answer:

n = m-a

Step-by-step explanation:

The formula is :  ...(1)

a is actual cost of an item

m is original price

n is amount of coupon

We need to solve the formula for the amount of coupen.

Subtracting m to the both sides of equation (1).

a-m = m-n-m

-n=a-m

or

n = m-a

So, the formula for the amount of coupon is n = m-a.

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
