Five whole number are written in order
4 6 x y 10
The mean and the median of the numbers are the same.
Work out the values of x and y
Thx for whoever helps me out
if the mean and the median are the same, that means that the middle number and 20+x+y/5 are the same, and because the median has to be a whole number, then 20+x+y/5 has to be a whole number as well, so x+y is a multiple of 5. (from here I guessed because there are limited answers) I got 7as x and 8 as y.
x is the median since it's the middle number and since it's the median, it's also the mean.
5x will be the sum of all the numbers since it's the mean.
5x = 20 + x+ y
4x = 20 + y
So, you can plug some numbers in and try them. But, x and y must remain in order so x must be greater or equal to 6, and also less than or equal to y.
x = 7
y = 8.
4(7) = 20 + 8
I hope this helped. :))
