Five whole numbers are written in order

4 6 x y 10

the mean and median of the five numbers are the same

work out the values of x and y

The values of x and y is given by the equation .

Step-by-step explanation:

Given : Five whole numbers are written in order  4 6 x y 10 , the mean and median of the five numbers are the same.

To find : The values of x and y ?

Solution :

Observations 4, 6, x, y, 10.

Mean is summation of observation divided by number of observation.

i.e.

Median is middle term of observations.

Median of odd terms term

term

The mean and median of the five numbers are the same.

i.e.

The values of x and y is given by the equation .

The mean is 77.9 so subtract each number from the mean (if it’s negative just keep the number the same and change it to positive). Once you have subtracted the mean from all the numbers (or vise versa as long as it’s positive) add the differences together and find the mean of them. There’s your answer. ☺️
