To calculate the mean you add all of the numbers together, and then divide by how many numbers were added. In this case, the mean is 21.

The range of these numbers, the difference between the highest and lowest of these numbers, is equal to 28-15 = 13.

It is (21+15)/2 = 36/2 = 18

(21+15+19+28+10+17+9+15+26+14+10+18+24+12+16) / 15 = 16.93 recurring (that is, 16.93333...)

Easy to figure out: put all of the numbers in order from least to greatest. Find the number that occurs the most and that is your mode. Or if the answer is obvious just find the number that occurs the most in the set. In this case 18is the answer.

5 clear references based on John 21:24 (John 13:23, 19:26-27, 20:2-8, 21:7, 21:20-24) Probably also John 18:15-16

14/21 * 15/18 = 2/3 * 5/6 = 5/9

I presume you don't mean 21 minus 13; that is easy enough, and equals 8. If you mean the ratio 13/21, all you do is divide. The answer is 0.1690___.

Mean = Sum/Count = 359/15 = 23.933...

Mean (12, 18, 19, 20, 21) = 18
