20. a shoe store owner had an employee record the shoe sizes purchased by customers during one hour on two different days. the
employee presented the results to the owner with the two dot plots shown. based on the data, which size of shoe should the owner
stock the most of in the store's inventory?
a. 8
b. 10
c.9
d. 11

The correct option is C. 9

Step-by-step explanation:

From the graphs shown in the attached file we can see that the maximum number of shoes bought were of size 9. On both days the number of size 9 shoes bought was 5 which was the highest number of shoes bought for any size shoe. Therefore since size 9 sell the most on both days the owner should stock most of size 9 shoes in the store's inventory.

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5
