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.
It is 3i.
The square root of -9 is the square root of -1 times the square root of 9.
So: the square root of 9 is 3, and the square root of -1 is called i (this doesn't actually exist, it's just imaginary).
Then, the square root of -9 is 3i.
