Arithmetic mean means that you need to add all the numbersand divide the sum by the number of numbers listed in the problem.
Therefore you add 8+12+15+21+11+x= 67 + x
Now you multiply 6 times 17, (because there are 6 numbers in the problem which are 8,12,15,21, and 11)
17x6=102
Now: 67+x=102
Solve for x
67+x=102
-67 -67
---------------
x= 35

9
What is the mean of 1 6 10 11 12?
The mean is 8 because: (1+6+10+11+12)/5=8 We know that the Arithmetic Mean of a data set = (sum of all the items)/ number of items. =(1+6+10+11+12)/5 =(40)/5 =8. The Arithmetic Mean of 1, 6, 10, 11, and 12 is 8.

If the average arithmetic mean of x 5x and 6x is 8 what is the value of x?
x + 5x + 6x = 12x. There are 3 terms. If the arithmetic mean is 8 then 12x = 3 x 8 = 24 : So, x = 24 ÷ 12 = 2.
