12 + 7 - 2 12 + 7 = 19 19 - 2 = 17 or 7 - 2 = 5 5 + 12 = 17
The average is 12.
There are probably tens of such sets. Some are: 5, 6, 7, 7, 8, 11, 13, 14, 15, 16, 17, 18 5, 6, 7, 7, 7, 12, 12, 14, 15, 16, 17, 18 5, 6, 7, 7, 7, 12, 12, 14, 14, 16, 17, 18 5, 6, 7, 7, 7, 12, 12, 14, 14, 15, 17, 18 5, 6, 7, 7, 7, 12, 12, 14, 15, 15, 17, 18 5, 6, 7, 7, 7, 12, 12, 14, 15, 16, 16, 18 5, 6, 7, 7, 7, 12, 12, 14, 14, 16, 16, 18
A Possible Answer could be: 70 9 12 12 10 5 1
the mean of the dataset 6, 7, 12, 14, 16, 17 is 12. to get the mean (or average) of a dataset, you add the numbers of the dataset together and then divide by the number of data (in this case there are 6 pieces of data) (6+7+12+14+16+17)/6 = 12
12 + 5 = 17 12 - 5 = 7 12 and 5 is the answer.
(7+9+17)/3= 11

The average is 12.
12 + 7 - 2 12 + 7 = 19 19 - 2 = 17 or 7 - 2 = 5 5 + 12 = 17
There are probably tens of such sets. Some are: 5, 6, 7, 7, 8, 11, 13, 14, 15, 16, 17, 18 5, 6, 7, 7, 7, 12, 12, 14, 15, 16, 17, 18 5, 6, 7, 7, 7, 12, 12, 14, 14, 16, 17, 18 5, 6, 7, 7, 7, 12, 12, 14, 14, 15, 17, 18 5, 6, 7, 7, 7, 12, 12, 14, 15, 15, 17, 18 5, 6, 7, 7, 7, 12, 12, 14, 15, 16, 16, 18 5, 6, 7, 7, 7, 12, 12, 14, 14, 16, 16, 18
The average = (18 + 12 + 13 + 17) ÷ 4 = 60 ÷ 4 = 15
There is no mode average. The median average = the mean average = (-2 + 17) ÷ 2 = 7½ = 7.5
