The temperature in Fahrenheit in a city on randomly selected days during the summer or 89 85 90 87 86 91-88 and 89 what is the mean temperature around your answer to one decimal place

Answer 1

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

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

Let's add them up:

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

Now, count the number of temperatures:

There are 8 temperatures.

Now, divide the total by the number of temperatures:

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

So, the mean temperature is 90.0°F when rounded to one decimal place.
