The mean average of the given numbers is 10
If you mean: 8 9 10 11 and 12 then the average mean is 10
A Possible Answer could be: 70 9 12 12 10 5 1
8+10+12=30 30/3=10 10 is the average of 8 12 and 10 If that's 812 and 10, the average is 411. If that's 8, 12 and 10, the average is 10.
8+10+12=30 30/3=10 10 is the average of 8 12 and 10 If that's 812 and 10, the average is 411. If that's 8, 12 and 10, the average is 10.
