Answer 2

Answer:

Mean = 9

Step-by-step explanation:

The mean is the average of a data set.  Given the values, 2, 9, 10, 12, 12:

Add all the numbers in the data set, and divide its sum by the number of items in the set:

Mean = $\frac{2+9+10+12+12}{5}$ =  $\frac{45}{5}$ = 9

Therefore, the mean of the given data set is 9.
