The arithmetic mean of 10, 11, and 6 is 9. Add them together then divide by 3.

5 +9 = 9 + 5 is an example of arithmetic commutativity

Median of the set = arithmetic mean of 8 and 9 = 8.5

To find the mean you add them all up then divide by the number of numbers so: 1+3+5+7+9+11 divided by 6 = 36/6 = 6

The answer to that arithmetic is 4,568.Do the math. Yeah no kidding do the math.....again it is 4,691.

The arithmetic mean of 10, 11, and 6 is 9. Add them together then divide by 3.

The answer depends on what you mean by 11 in(n) a half - which is not an expression that is recognised.

The mean average is (7 plus 11) divided by 2 = 9

5 +9 = 9 + 5 is an example of arithmetic commutativity

Median of the set = arithmetic mean of 8 and 9 = 8.5

-9

To find the mean you add them all up then divide by the number of numbers so: 1+3+5+7+9+11 divided by 6 = 36/6 = 6

9 + 22 + 11 = 42

(-9) + (-11-4) + (-11-63) =-9 - 11 - 4 - 11 - 63 = -98

10+11+9+3= 33

11 + 7 + 9 = 27
