To find the mean (average) of a set of data, you need to sum up all the numbers in the set and then divide the sum by the total number of values.
Let's calculate the mean of the given data set: 7, 5, 9, 5, 12.
Step 1: Add up all the numbers in the set:
7 + 5 + 9 + 5 + 12 = 38
Step 2: Divide the sum by the total number of values (which is 5 in this case):
38 / 5 = 7.6
So, the mean of the given data set is 7.6.
The correct option is (D) 7.6.
