Use distributive property
-28y+8y= -20y
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.
The worksheet pic is not clear
7.50 X 315 =2362.50 at the lower price
7.75 X 315 = 2441.25 at the higher price
subtract 2362.50 from 2441.25 you get 78.75
Answer:
Step-by-step explanation:
P(B)=7/(2+7+7)
P(B)=7/16
P(B)=0.4375
