Question

5.

The temperatures in five cities were 3° F, -5° F, 70 F,-90 F, and -13° F. What was the
mean temperature of the five cities? (Write your answer as a decimal).

Answer 1

Explanation:

the mean value is the sum of all values divided by how many values there are.

so,

(3 + -5 + 70 + -90 + -13) / 5 = -35/5 = -7

-7° F is the mean temperature of the 5 cities.
