lcd(22, 12, 16, 9) = 1584 22 = 2 x 11 12 = 2^2 x 3 16 = 2^4 9 = 3^2 lcd = 2^4 x 3^2 x 11 = 1584
5+7+9+12+12 = 45 and 45/5 = 9 which is the mean average
The LCM of 8, 9, 12, and 16 is 144.
10
12 + 22 + 32 + 42 + 52 = 1 + 4 + 9 + 16 + 25 = 55
the average of 7,9,11,12,16 is = (7+9+11+12+16)/5 =11
lcd(22, 12, 16, 9) = 1584 22 = 2 x 11 12 = 2^2 x 3 16 = 2^4 9 = 3^2 lcd = 2^4 x 3^2 x 11 = 1584
Mean is the same as average
The LCM is: 1,584
12
It can range anywhere from 9 to 16..the average age is 12.
4, 6, 8, 9, 10, 12, 14, 15, 16, 18 The average is 11.2
5+7+9+12+12 = 45 and 45/5 = 9 which is the mean average
12, 22, 32, 42, 52
26
The mean of those numbers is equal to 12.916 recurring (that is, 12.91666....)
Average = (9+13)/2 = 22/2 = 11
