The measures of variability for each class are listed:
Class A: Class B:
Range : 30 Range: 30
IQR: 12.5 IQR: 20.5
MAD: 7.2 MAD: 9.2
The interquartile range and the mean absolute deviations for class B are larger number therefore indicating that there is more variability in that data set.
Answer:
Tom = 5
Susan = 3
Step-by-step explanation:
FROM THE BOXPLOT :
Tom's IQR :
IQR = Q3 - Q1
Q3 = third quartile (value at the endpoint of the box)
Q1 = 1st quartile (value at the beginning of the box)
IQR = 9 - 4
IQR = 5
SUSAN :
IQR = Q3 - Q1
Q3 = third quartile (value at the endpoint of the box)
Q1 = 1st quartile (value at the beginning of the box)
IQR = 8 - 5
IQR = 3
Answer:
x=32, y=17
Step-by-step explanation:
Difference between two numbers is 15:
x-y=15
Greater number (x) is two less than twice the lesser number:
x=2y-2
-----
x-y=15,
x=2y-2.
x-y-x=15-2y+2
-y=15-2y+2
y=15+2
y=17
-----
x-y=15
x-17=15
x=17+15
x=32
Answer:
D
Step-by-step explanation:
It must first translate 1 unit to the left because quadrilateral F'G'H'I is one unit away from to y axis. It can then translate across the y-axis.
Given:
About 3/5th of the registered voters participated in 2016 election.
California has 25 million registered voters.
To find:
The number of registered voters who participated in 2016 election.
Solution:
We have,
Total number of registered voters = 25 million
According to the question,

Now,



Therefore, there are 15 millions of registered voters who participated in 2016 election.
