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.
