A) how many men have a waist measurement of more than 85 cm b) what is the median waist measurement
c) what is the interquartile range of the waist measurements

(a)29

(b)91cm

(c)13cm

Step-by-step explanation:

(a)From the graph, 11 men have a waist measurement of 85cm and below.

Since the cumulative frequency is 40

Number of men who have a waist measurement of more than 85 cm

(b)Median

Tracing 20 from the y-axis to the x-axis, the median waist measurement is 91cm.

(c)Interquartile Range

Interquartile Range =

From the graph, at y=10, x=84 cm

From the graph, at y=30, x=97 cm

Therefore:

Interquartile Range=97-84=13cm

c(x)= 6x + 3

step-by-step explanation:

hi there

the slope is 1/3.

this is because from the y-intercept, you go up one, and you go to the right three, to get to the next exact point on the graph. this is known at the “rise over run.”

p.s. (if you need it).your y-intercept is -2, because that is the point on the graph where the line crosses the y-axis.

hope that : )
