Answer:

Step-by-step explanation:

The mean of a group of numbers is determined by adding all numbers together and then divided the sum by the total number of numbers.

For example: the mean of 1, 19, 100 = (1+19+100)/3 = 120/3 = 40

Lets say your numbers are these...

10,20,30,40,50,60,70,80,90 and 100

you would add those to get 650

Now how many numbers did you add?

You added 10

so now divided

650 by 10

you get 65

that is the mean of those numbers!
