Answer:
(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
m(w) = 8w + 17 looks like the best answer choice for me
1+2 is 3 -6 is -3

Answer: f) $3,000
Step-by-step explanation:
Given: Simple interest amount S.I.= $180.00
The rate of interest annually= 6%
In decimal , the rate of interest annually r = 0.06
Time period t = 1 year
Let 'P' be the principal amount invested in account.
The formula to calculate simple interest is as :-


Hence, the principal amount invested in account = $3000
Answer: The equation of a linear relationship is y = mx + b, where m is the rate of change, or slope, and b is the y-intercept (The value of y when x is 0).
