Answer:
Step-by-step explanation:
-4s - 7 = 29 + 5s
Subtract 5s from both sides [-4s - 5s - 7 = 29 + 5s - 5s]
-9s - 7 = 29
Add 7 to both sides [-9s -7 +7 = 29 + 7]
-9s = 36
Divide both sides by (-9) [-9s/-9 = 36/-9]
s = -4
Answer:
C) The mean of this data set is 12.
Step-by-step explanation:
When you add all of the numbers together you get 102.
13+11+16+12+42+8 = 102
Divide this by 66 because that is how many numbers are being used.
102/6 = 17 is the mean
