Question

find the mean and median of all positive factors of 48

Answer 1

Possible factors of 48 are 1, 2, 3, 4, 6, 8, 12, 16, 24, 48
Mean = (1+2+3+4+6+8+12+16+24+48)/10
Median=8

Answer 2

Answer:  The required mean is 12.4 and median is 7.

Step-by-step explanation:  We are given to find the mean and median of all positive factors of 48.

The positive factors of 48 are 1, 2, 3, 4, 6, 8, 12, 16, 24 and 48.

So, there are total 10 positive factors of 48.

Therefore, mean is given by

$m=\dfrac{1+2+3+4+6+8+12+16+24+48}{10}=\dfrac{124}{10}=12.4.$

And, median is given by

$M=\dfrac{(5th-value)+(6th-value)}{2}=\dfrac{6+8}{2}=\dfrac{14}{2}=7.$

Thus, required mean is 12.4 and median is 7.
