80
75 + 70 + 80 = 225
80 + 85 + 90 = 255
225 + 255 = 480
six numbers so 480 / 6 = 80
Median of the set = arithmetic mean of 75 and 85 = 80
73.75
70, 75, 80, 85, 90 and 95.
65, 70, 75, 80, 85.
The average of 80, 80 and 95 is 85.
I am twelve and I can throw about 70-75 mph. For an average child maybe 80-85 mph.
70, 72, 74, 75, 76, 77, 78, 80, 81, 82, 84, 85 (including 70 and 85)
Median of the set = arithmetic mean of 75 and 85 = 80

To find the mean of the numbers 60, 65, 70, 75, 80, 85, 90, 95, and 100, first add them together: 60 + 65 + 70 + 75 + 80 + 85 + 90 + 95 + 100 = 750. Then, divide the total by the number of values, which is 9. Therefore, the mean is 750 ÷ 9 = 83.33.

65, 70, 75, 80, 85, 90 and 95.
To calculate the mean absolute deviation (MAD) of the numbers 65, 90, 85, 70, 70, 95, and 55, first find the mean, which is 75. Then, calculate the absolute deviations from the mean: |65-75|, |90-75|, |85-75|, |70-75|, |70-75|, |95-75|, and |55-75|, resulting in the values 10, 15, 10, 5, 5, 20, and 20. The average of these absolute deviations is the MAD, which equals approximately 11.43.
