the average is about 12-15 darts the best is 9 darts
The average of 9, 15, 11, and 13 is 12. It is calculated by adding all the numbers together (9+15+11+13 = 48) and then dividing by the total number of values (4).
3 It is 12 more than -9 and 12 less than 15 9 + 15 = 24 24/2 = 12 -9 + 12 = 3 15 - 12 = 3
The average is 15.
Mean is the same as average
The GCF of 9, 12, 15 is 3.
(12+15+18)/3 = 15
4, 6, 8, 9, 10, 12, 14, 15, 16, 18 The average is 11.2
5+7+9+12+12 = 45 and 45/5 = 9 which is the mean average
15 +26+9+12
It is: (15-7)*(12-9) = 24
