Question

The energy usages per day (in kilowatt-hours) of houses on Hamlet Avenue are listed below. \qquad 30, 23, 38, 36, 3330,23,38,36,3330, comma, 23, comma, 38, comma, 36, comma, 33 Find the mean energy usage per day

Answer 1

32

Explanation:

Add 30, 23, 38, 36, and 33. This equals 160.

There are five numbers in this problem, 30(1), 23(2), 38(3),36(4), and 33(5).

Because there are five numbers, you divide 5 by the sum of the five numbers, which is 160. (5 divided by 160 or 5/160)

You then get the answer 32.

Answer 2

32 kilowatt-hours.

Explanation:

The energy usages per day (in kilowatt-hours) of houses on Hamlet Avenue are listed below:

=
`(30 + 23 + 38 + 36 + 33)/(5)`

= 32 kilowatt-hours.
