Answer:
16
Step-by-step explanation:
The mean is all the numbers i the set added together, then divided by the number of terms. For example:
1 2 3
1+2+3
6
6/3=2
2 would be the mean.
So:
[tex]7+16+11+12+10+16\\23+11+12+10+16\\34+12+10+16\\46+10+16\\56+16\\72\\\\\frac{72}{6}=12[/tex]
16 is the missing value of the set if the mean is 12.
Finito.
