Question
Solution 1
To find the value of x, we first need to understand that the mean (average) of a set of numbers is the sum of the numbers divided by the quantity of numbers.
Given that the mean of the data is 9.5, we can set up the following equation:
(9.5 + 5 + x + 11 + 12 + 15 + x + x + 5 + 7) / 10 = 9.5
