Question

The low temperatures for one week at a ski resort were: -24, -15, -21, -32, -18, -9, & -14. What was the mean low temperature at the resort for the week?

Answer 1

add the temps up
-24 + (-15) + (-21) + (-32) + (-18) + (-9) + (-14) = -133
now divide by how many numbers there are
-133/7 = -19 <== the mean (average)
