4 - (-5) = 4 + 5 = 9.
3, 4, 5, 6, 7, 8, 9, 10, 11
5. 3+6+9+2 = 20 20 / 4 = 5. To calculate the average of a series of numbers you have to add them together and divide them by the amount of numbers given.
5+7+9+12+12 = 45 and 45/5 = 9 which is the mean average
5 + 4*(3-2) = 9(5 - 4)*3^2 = 9 - 5 + 4 * 3 + 2 = 9
Average = (8 + 9 + 5 + 6)/4 = 7Average = (8 + 9 + 5 + 6)/4 = 7Average = (8 + 9 + 5 + 6)/4 = 7Average = (8 + 9 + 5 + 6)/4 = 7
The mean is the arithmetic average. The average of 4 9 7 4 & 1 is 5
hai
The average is 5.
The first 5 composite numbers are 4, 6, 8, 9, and 10. 4 + 6 + 8 + 9 + 10 = 37, so their average is 37/5, or 7.4.
between 4" 9' and 5"4'
Add the 3 numbers together and divide that answer by 3. Example: The average of 2, 4, and 9. Average = (2+4+9)/3 = 15/3 =5.

Stanines of 1,2, and 3 are below average, 4, 5, and 6 are average, and 7, 8, and 9 are above average.
4 - (-5) = 4 + 5 = 9.
When there is an even number of data items the median is the mean average of the middle two. → median of {2, 3, 4, 5, 7, 9} = (4 + 5)/2 = 9/2 = 4.5
