28
17 plus 15 plus 13 equals 45.
45 divided by 15 is 3
19, 20, 24, 25, 37, 45, 48, 57, 78, 88, 98 Mean: 49 Median: 45 Range: 79 There is no mode.
39/45 = (3*13)/(3*15) = 13/15

all you do is this example 12 19 20 21 45 before you do it put it in order then cross out side by side like you would cross out 12 and 45 then 19 and 21 then your median would be 20
17 plus 15 plus 13 equals 45.

The median is 45.
45 divided by 15 is 3
19, 20, 24, 25, 37, 45, 48, 57, 78, 88, 98 Mean: 49 Median: 45 Range: 79 There is no mode.
39/45 = (3*13)/(3*15) = 13/15
They are: 13 to 15 and 39 to 45
It is 31, the number between the two middle numbers when they are arranged in order.
