Question

Find the mean of this group of numbers: 11, 17, 13, 16, 18

Answer 1

Answer: 15

Step-by-step explanation: Mean is all the numbers added together and divided by the number of numbers that you added.

11 + 17 + 13 + 16 + 18 = 75

75 divided by 5, is 15.

Answer 2

The mean is 15.

Explanation:

Our task is to find the mean of this group of numbers:

11, 17, 13, 16, 18

To find the mean, add all these numbers:

11 + 17 + 13 + 16 + 18

= 75

Next, divide by 5 (because there are 5 numbers in the set):

75 ÷ 5 = 15

Therefore, the mean is 15.
