Answer:

Group A.

Step-by-step explanation:

As shown by the dot plots, Group A has one 9-year-old painter, seven 10-year-old painters, and 24 painters between the ages of 15 and 20. Group B has seventeen painters between the ages of 10 and 20 and thirteen painters between the ages of 25 and 30. Since mean is the average of everything, Group A most likely has a lower mean age of painting students than Group B does.

<span>Part A: Solve A = (x + 23) for x.

A = x + 23

=> A - 23 = x + 23 - 23

=> A - 23 = x

=> x = A - 23 <------- answer

Part B: Determine the value of x when A = 108

Replace the value of A in the expression x = A - 23

x = 108 - 23 = 75

x = 75 <------- answer

Part C: Solve -np - 90 > 30 for n.

-np - 90 > 30

=> -np + np - 90 >30 + np

=> - 90 > 30 + np

=> -90 - 30 > 30 - 30 + np

=> -120 > np

=> np < - 120 <----- answer
