Question

Five whole numbers are written in order. 4 6 x х у 10 The mean and median of the five numbers are the same. Work out the values of x and y.​

Answer 1

Answer:

First think about how you calculate a mean - addd the numbers and then divide by hoow many there are.

4+6+x+y+10 / 5

Simplify

20+x+y / 5

Now think about the median - the middle number, which in this case must be x.

If the mean and median are the same we can make an equation:

20+x+y /5 = x

Now we can use rearranging skills to Simplify this

20+x+y = 5x

20+y = 4x
