What is the average for the following set of measurements?
27°c, 12°c, 31°c, 19°c, 23°c, 11°c, 17°c
o a 7°c
o b. 140°c
o c. 28°c
o d. 20°c

D

Explanation:

1. add them all up

27 + 12 + 31 + 19 + 23 + 11 + 17

39 + 50 + 34 + 17

89 + 51

140

2. divide them by the number of number sets in the problem

140 ÷ 7

20
