If you mean: 2 times (8+7)-6 then divided by 2 times (9-3) then the answer is 2
2+3+7+9+3=24
The average or mean of 3, 5, 7, 9, and 11 is 7.
the awnser will be 7 3+3=6+3=9 9-2=7-0=ANS=7
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
