+ 33
=210
210/10=21
Yes! 21 is the mean of these numbers.
Whew..thank you. Starting to get some of this now.
Great! :-)
To find the mean of a set of numbers, you need to add up all the numbers in the set and then divide the sum by the total number of values in the set.
Let's follow the steps to find the mean of the given set of numbers:
Step 1: Add up all the numbers in the set:
13 + 15 + 18 + 18 + 18 + 19 + 22 + 26 + 28 + 33 = 210
Step 2: Divide the sum by the total number of values in the set:
210 / 10 = 21
Therefore, the mean of the given set of numbers is 21.
