The temperatures (in ° F) in a city on randomly selected days during the summer are 89, 85, 90, 87, 86, 91, 88, and 89. What is the mean temperature? Round your answer to one decimal place.(1 point)

The mean temperature is calculated by adding up all the temperatures and then dividing by the number of temperatures.

Adding up all the temperatures:
89 + 85 + 90 + 87 + 86 + 91 + 88 + 89 = 705

Dividing by the number of temperatures (8):
705 / 8 = 88.1

The mean temperature is 88.1°F.
