The average is (11+11+13+17)/4 = 52/4 = 13
13.285714 repeating
It is: 13+9+11 = 33 and 33/3 = 11 which is the mean average
Average is more correctly called the MEAN in mathematics. To find the mean , add all the terms and divide by the number of terms. Hence mean = (11+13+17+23) / 4 Mean = ( 64) / 4 mean = 16 The Answer!!!!!
Add them together and divide by the number of values (4).
11 13 17
13. (9+17)/2=13
11, 13, 17, 19
The LCM of 11, 13, and 17 is 2431
Average: (13+9)/2 = 11
Average = 13
7 x 11 x 13 x 17 = 17017
