The composite numbers upto 28 are: 4, 6, 8, 9, 10, 12, 14, 15, 16, 18, 20, 21, 22, 24, 25, 26, 27, 28.Of these the ones that sum to 28 are: 4 and 24, 6 and 22, 8 and 20, 10 and 18, and 12 and 16. And out of these pairs the ones that have a gcd of 4 are: 4 and 24, 8 and 20, and 12 and 16.So two composite numbers that have a gcd of 4 and a sum of 28 can be either: 4 and 24, 8 and 20, or 12 and 16.
The standard deviation of 20 22 26 28 34: σ=5.4772
16 = 2428 = 22 * 744 = 22 * 11greatest common denominator: 22 = 4
The average of a series of numbers is their sum divided by however many numbers there are: in this case you would calculate: (16 + 40) / 2 =56 / 2 =28 Therefore the average of 16 and 40 is 28.
16 18 22 28 The median (middle number when numbers are in numerical order) is 20.
The modes are 4 and 16. The median is 16. The average is 16.
12, 14, 16, 18 20, 22, 24, 26, and 28, so all of them are even

to try out you have to be ages 16-28
= 144 / 7 or approximately 20.57
Median of 16 and 28 is (16+28)/2 = 22
The difference between 72 and 16
20+8, DUH!
The Least Common Multiple (LCM) for 28 20 16 is 560.
The LCM of 16, 20, and 28 is 560
The median is 19.
