You need to add all four numbers first. Then divide the sum by 4 to find the mean.

Answered by dk
the median is 105 and 107
and i don't about mode
Answered by Ms. Sue
The median is half way between 105 and 107 -- so the median is 106.

This set of numbers doesn't have a mode. All of the numbers are different.

How do you think you can solve the last problem?

10.00-1.50=$8.50 he receive back
and my son did 2:50+1:50=4:00 then he subtract 10:00-4:00 =$6:00 he receive back
Answered by Ms. Sue
He played 4 games. So we multiply 1.50 times 4 = $6.00.

He paid $2.50 to rent shoes.

$2.50 + $6.00 = $8.50

$10.00 - 8.50 = ? change

Answered by dk
10.00-8.50=$1.50

Right. :-)
