To find the average of a set of numbers, you add all the numbers together and then divide by the total number of values. In this case, the sum of 8, 9, 10, 11, and 12 is 50. To find the average, you divide 50 by the total number of values, which is 5. Therefore, the average of 8, 9, 10, 11, and 12 is 10.
The mean (average) of those numbers is 16.
The average is 10.
8, 9, 11 and 12
Well, darling, to find the average of those numbers, you add them all up (that's 8+10+12+14+16) and then divide by how many numbers there are (which is 5 in this case). So, 8+10+12+14+16 = 60, and 60 divided by 5 is 12. So, the average of those numbers is 12.
