The mean of the data set(9,5,y,2,x) is twice the data set(8,x,4,1,3).what is (y-x)

Step-by-step explanation:

Given

Set 1: (9,5,y,2,x)

Set 2: (8,x,4,1,3)

Required

(y - x)

First the mean values of set 1 and set 2 has to be calculated

For set 1

Collect like terms

For set 2

Collect like terms

Given that the mean of set 1 is twice the mean of set 2;

Multiply both sided by 5

Open bracket

Subtract 16 from both sides

Subtract 2x from both sides
