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:
[tex]\frac{20}{4}[/tex]=5
We have another set of three numbers whose mean is 12. We can write that as:
[tex]\frac{36}{3}[/tex]=12
To find the mean of the seven numbers together, we can add the values together and divide by 7:
[tex]\frac{20+36}{7}[/tex]=[tex]\frac{56}{7}[/tex]=8
