Question

HELP!!! ASAP!!! Find the mean of the following data set:
{2, 2, 2, 7, 9, 4}
Thanks!

Answer 1

The 'mean' of a number set is the average.

To find the mean of this data set, we'll need to add all the numbers together.

2 + 2 + 2 + 7 + 9 + 4 = 26

From there, we'll need to divide this total by the amount of numbers in the sequence.

Since this data set has 6 numbers, we'll divide by 6.

26 / 6 = 4.333333.

Therefore, the mean of this data set is ~4.3.

Hope this helps you! :)

Answer 2

4.3333333 (Non-terminating and repeating)

Explanation:

Add the numbers in the data set together:

2 + 2 + 2 + 7 + 9 + 4 = 26

Now divide this by the number of terms in the set, which is 6.

26 / 6 = 4.3333333 (Non-terminating and repeating)
