Find the Interquartile Range for Marcus's data.
A.4.5
B.2
C.6
D.2.5

How I got that

The data set for Marcus is

2, 3, 5, 6, 6, 6, 7, 7, 7, 7, 7, 7, 8, 8, 8, 8, 8, 9, 10, 10

The five number summary is

So the interquartile range (IQR) is

IQR = Q3 - Q1

IQR = 8 - 6

IQR = 2

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
