°F

Answer 1

To find the mean temperature, you add up all the temperatures and then divide by the number of temperatures.

The temperatures are: 89, 85, 90, 87, 86, 91, 88, and 89.

1. Sum the temperatures: \( 89 + 85 + 90 + 87 + 86 + 91 + 88 + 89 = 89 + 85 + 90 + 87 + 86 + 91 + 88 + 89 = 718 \)

2. Count the number of temperatures: There are 8 temperatures.

3. Calculate the mean: \[ \text{Mean} = \frac{\text{Sum of temperatures}}{\text{Number of temperatures}} = \frac{718}{8} = 89.75 \]

Rounding this to one decimal place gives: \[ \text{Mean temperature} = 89.8°F \]

Thus, the mean temperature is 89.8°F.
