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
Answer:
the length of segment AB is 14
Step-by-step explanation:
If Both shapes are the same just from different angles, that means segments AB and RQ are the same. Here is the equations:
3(x) + 8 = ???
3(2) + 8 = 14
5(x) + 4 = ???
5(2) + 4 = 14
A variable can only represent one number, in this case x was equal to 2, and as a result both solutions, AB and RQ were equivalent to each other, therefore:
Symplified Answer: The Length Of Segment AB Is 14.
To find the mean absolute deviation, u have to find the mean of the data set first. after u find the mean, u subtract to find the numbers distance from the mean. after u do that, u then add up all the new numbers and then divide by how many numbers there are in the data set, and whatever ur answer ends up being is the mean absolute deviation of ur data set.
Answer:
= 32√3 ft²
Step-by-step explanation:
Area of the trapezoid will be equal to the area of the square and that of the triangle.
Considering the triangle part;
Cos 60 = x/8
x = 8 × sin 60
= 4
Base of the triangle part = 4 ft
Therefore, top of the trapezoid = 6 ft
Height = 8 × sin 60
= 8 × √3/2
= 4 √3
Area of the trapezoid
Area = ((a+b)/2) × h
= ((6 + 10 )/2 )× 4√3
= 16/2 × 4√3
= 32√3 ft²
Total number of apples purchased by Molly = 8
Total cost of the apples = $2.96
Since, Molly divided 2.96 by 8.
We have to determine the reason, for which Molly performed the calculation.
So, he divided the total cost $2.96 by '8', that is the number of apples in order to find out how much she paid per apple.
So, 
So, $0.37 is the cost of per apple.
