Hey there!

The mean of the numbers is the <u>average</u>. To find the mean we will simply add all the numbers together, and divide them by the amount of numbers there are. Easy, peesy, lemon squeezy. Lets get started.

7 + 10 + 22 + 10 + 12 + 10 + 12 = 83

Now that we have added those altogether, we can divide them by the amount of numbers there are. The amount of numbers there are comes to a total of 7. Therefore...

83 divided by 7 = 11.857

Answer Choice B. 11.9 is your correct answer.
