What is the average value?
The average value (mean) is:
30 ÷ 5 = 6
To find the average value (mean), you need to divide the sum of the numbers by the number of values.
We already know that the sum of the numbers is 30.
And since there are 5 numbers given (9, 2, 8, 9, 2), you divide the sum by 5:
30 ÷ 5 = 6
Therefore, the average value (mean) is 6.
