What is the interquartile range for the data set? ?

65

Step-by-step explanation:

You should get 71-6 at the end which is 65.

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:

7,24
