What is the difference between the mean and the median of the data set?
{22, 8, 10 ,18 ,12, 20}

The difference is 0.

Step-by-step explanation:

The given data set is

{22, 8, 10 ,18 ,12, 20}

The mean is given by;

To find the median, arrange in order.

8, 10 ,18 ,12, 20,22

The median is the average of the two middle terms;

Difference:

15-15=0

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
