°F

Answer 1

To find the mean temperature, you first need to sum all the temperature values and then divide by the number of temperatures.

Here are the temperatures given:

89, 85, 90, 87, 86, 91, 88, 89

Now, sum these values:

\[ 89 + 85 + 90 + 87 + 86 + 91 + 88 + 89 = 89 + 85 + 90 + 87 + 86 + 91 + 88 + 89 = 720 \]

Next, count the number of days (temperatures) which is 8.

Now, divide the total sum by the number of temperatures:

\[ \text{Mean} = \frac{720}{8} = 90 \]

Thus, the mean temperature is:

\[ \boxed{90.0} , \text{°F} \]
