Average = Sum/Count = 30/3 = 10
You cannot. It should be their weighted average with the weights representing the number of observations in each average.For example, if 3 numbers have an average of 10 and 6 numbers have an average of 20, the combined average is not the average of 10 and 20 (which is 15).It is, in fact, (3*10 + 6*20)/(3 + 6) = (30+120)/9 = 150/9 = 16.66...You cannot.

25/30 + 22/30 = 47/30
6x5=30 10x3=30 30 is a multiple of 6 and 10
30, 42, 38
3+7+2+8+10 = 30 30 ÷ 5 = 6 Average = 6

6 . the 5 numbers add up to 30 30 divided by that 5 is 30/5 = 6
(8+16+6) / 3 = 30 / 3 = 10
1, 2, 11, 221, 2, 3, 5, 6, 10, 15, 30
(30 + 16 + 6 + 22) / 4 = 18.5
12 +12+6=30 30/3=10 to find the average of something you add up the values and divide the total by the number of values you had
They are 6, 10, 14, 18, 22, 26 and 30.
