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.
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
The average of -9 and 15 is +3 .
