Question

The mean of a data set of 6 numbers is 8. The mean of a different data set of 6 numbers is 20. Whats the mean of the combined data sets?​

Answer 1

HERE IS YOUR ANSWER HOOMAN:

8

STEP BY STEP EXPLANATION FAM:

We have a set of four numbers and the mean is 5. We can see that the sum of the values is 20:

`(20)/(4)`=5

We have another set of three numbers whose mean is 12. We can write that as:

`(36)/(3)`=12

To find the mean of the seven numbers together, we can add the values together and divide by 7:

`(20+36)/(7)`=
`(56)/(7)`=8
