20 = (14 + 26 + 16 + 24) / 4
average = Sum of all terms / No. of terms = ( 31 + 29 + 26 + 27 + 32 ) / 5 = 145 / 5 = 29 therefore the average is 29!
26% of 31 = 26% * 31 = 0.26 * 31 = 8.06
When put in order, the numbers are: 16, 18, 24, 25, 26, 27, 31, 32 and 2123. The median is the middle number, which is 26. If you mean the 2123 to be 21 and 23, then the numbers are: 16, 18, 21, 23, 24, 25, 26, 27, 31 and 32. In this case, there is an even amount of numbers, so the median is the value halfway between the two middle numbers. They are 24 and 25, so the median is 24.5 as your answer.
The composite numbers between 21 and 31 are: 21 22 24 25 26 27 28 30
31 + 26 + 24 = 81 / 3 = 27 To find the above average, add the the three numbers together, then divide by 3
20 = (14 + 26 + 16 + 24) / 4
average = Sum of all terms / No. of terms = ( 31 + 29 + 26 + 27 + 32 ) / 5 = 145 / 5 = 29 therefore the average is 29!

My son is 14 months and he is over 30 pounds and about 33 inches. I know this is not average because they are suppossed to be around 31 inches and 24-26 pounds.
26% of 31 = 26% * 31 = 0.26 * 31 = 8.06

It's a case of putting them in order and picking the middle one (or average of middle two). In this case it's 29.5
31 + 24 + 28 + 33 + 28 + 27 + 25 = 196/7 = 28
The mass number of an atom is the sum of its protons and neutrons. In this case, the iron isotope has 26 protons and 31 neutrons, so the mass number would be 26 + 31 = 57.
