Hello!

To find the interquartile you first have to find the median

20, 25, 30, 40, 40, 48, 50, 62

The median is 40

To find quartile 1 you find the median of the numbers less than 40

20, 25, 30

Quartile 1 - 25

To find quartile 3 you find the median of the numbers higher than 40

48, 50, 62

Quartile 3 - 50

The answers are
Quartile 1 - 25
Quartile 3 - 50

Hope this helps!

Answer:

$P = 8 + 2\sqrt{26}$

Step-by-step explanation:

Given

$W = (-2, 4)$

$X = (2, 4)$

$Y = (1, -1)$

$Z = (-3,-1)$

Required

The perimeter

First, calculate the distance between each point using:

$d = \sqrt{(x_1 - x_2)^2 + (y_1 -y_2)^2$

So, we have:

$WX = \sqrt{(-2- 2)^2 + (4-4)^2 } =4$

$XY = \sqrt{(2- 1)^2 + (4--1)^2 } =\sqrt{26}$

$YZ = \sqrt{(1- -3)^2 + (-1--1)^2 } =4$

$ZW = \sqrt{(-3--2)^2 + (-1-4)^2 } =\sqrt{26}$

So, the perimeter (P) is:

$P = 4 + \sqrt{26} + 4 + \sqrt{26}$

$P = 8 + 2\sqrt{26}$

16.79+28.49=45.28

50-45.28=4.72

Kelly would get $4.75 back
