Question

find the arithmetic mean of all the factors of 20

Answer 1

Mean=Total of numbers / number of numbers.

Factors of 20=1,2,4,5,10,20
Total of munbers= 1+2+4+5+10+20=42
Number of numbers= 6

Therefore, mean=42/6=7

Hence the arithmetic mean of all the factors of 20 is 7
Ans==7

Hope this helps!

Answer 2

Answer:factor of 20=1,2,4,5,10,15and20
