Question

What is the mean of the snowfall amounts ?????

Answer 1

Hello!

First you'll need to add all of the inches of snowfall together.

15+11+18+25+13+20+16+28+15+18=179

Next you'll need to divide 179 by the number of numbers that were added together

179/10=17.9

Once you've done that, your mean will be 17.9 inches

I hope this helps!

Answer 2

To find the mean, you add up all the snowfall amounts and then divide that total by the number of snowfall years.
Your answer is 17.9 inches.
