Answer 1

Option B:

The mean low temperature of last week is 6.

Solution:

The daily low temperatures are:

-2°F, -3°F, -1°F, 8°F, 10°F, 12°F and 18°F.

Sum of the daily temperatures = -2 - 3 - 1 + 8 + 10 + 12 + 18

= 42

Number of days of the week = 7

`$\text{Average}=\frac{\text{Sum of the temperatures}}{\text{Number of days}}`

`$=(42)/(7)`

Average = 6

The mean low temperature of last week is 6.

Option B is the correct answer.
