Answer:
Graph B
Step-by-step explanation:
Slope: 2/1
Y-Intercept: -3
72-63=9
9/72=13%
13% IS .13 SO TENTH IS .1
I AM NOT SURE ABOUT THE TENTH
You can try then by plotting the points in.
The answer is C
Make sure by plotting in the points, lets take (-5,27)
y = 12 -3(-5)
y = 12 + 15
y = 27
27 = 27
This is correct
Lets try (-1,15)
y = 12 -3(-1)
y = 12 + 3
y = 15
15 = 15
This is correct
Lets try (8,-12)
y = 12 -3(8)
y = 12 - 24
y = -12
-12 = -12
This is correct too.
The correct ordered pairs are <span>C(-5,27),(-1,15),(8,-12)</span>
Answer: -9 and 7
Step-by-step explanation: 
and 
Place the values in ascending order first:
4, 10, 10, 11, 12, 12, 12, 12, 13, 13, 15, 15, 17, 18, 19, 20
There are 16 values
IQR is 3/4th term - 1/4th term
The 12th value is 15 while the 4th value is 11
Therefore IQR = 15-11 which is 4
I would say the outlier is 4.
Justification: Figure out the mean with the value of 4 then discount it to see whether the mean is affected by the outlier.
