To find the mean of the numbers 9, 12, and 15, you add them together to get 36. Then, you divide the sum by the number of values, which is 3. Therefore, the mean is 36 divided by 3, resulting in 12.
-1
The mean is 12.4
Yes if you mean dimensions of 9 by 12 by 15
First put them in ascending order. 1, 5, 7, 9, 9, 12, 14, 15, 18 Mean is 10 Median is 9 Mode is 9 Range is 17
3 It is 12 more than -9 and 12 less than 15 9 + 15 = 24 24/2 = 12 -9 + 12 = 3 15 - 12 = 3
12
Mean = 12 Median = 9 Range = 12
3, 6, 9, 12, 15 The mean is 9.
-1
The mean is 12.4
Yes if you mean dimensions of 9 by 12 by 15
Mean is the same as average
One possible set is {9, 9, 10, 11, 12, 15, 18}
First put them in ascending order. 1, 5, 7, 9, 9, 12, 14, 15, 18 Mean is 10 Median is 9 Mode is 9 Range is 17
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 GCF of 9, 12, 15 is 3.
The mean absolute deviation is 2
