Question

The daily low temperatures from last week are shown below. (The measurement is fahrenheit)

-9, -8, -7, 8, 10, 12, 18
What is the mean low temperature of last week?
A.-2
B.6
C.8
D.10

Answer 1

The mean low temperature can be found by adding all the temperatures together and then dividing by the total number of temperatures.

-9 + (-8) + (-7) + 8 + 10 + 12 + 18 = 24

24 divided by 7 (total number of temperatures) = 3.43 although 3 isn’t one of the answers A -2 is the answer since it’s the closest number to 3.

Rounding to the nearest integer, we get:

3

Therefore, the mean low temperature of last week is 3°F.

Hence, the answer is not in the options provided.
