Answer:
72z+176
Step-by-step explanation:
36z+28+8z+40+12z+60+48+16z=
36z+8z+12z+16z+28+40+60+48=
72z+176
First you turn 20% into a decimal by dividing by 100 and you get .20
then you multiply .20 by 160 and get 32
then subtract:
160-32=128
So if you have 120 bananas and you have a 20% decrease then you would have 128 left over
Hope this helped!! :D

B. The answer is the same irrespective of the sample sizes.
Step-by-step explanation:
Given that an article in the November 1983 Consumer Reports compared various types of batteries. The average lifetimes of Duracell Alkaline AA batteries and Eveready Energizer Alkaline AA batteries were given as 4.1 hours and 4.5 hours, respectively
Let X be the sample average lifetime of 81 Duracell and Y be the sample average lifetime of 81 Eveready Energizer batteries.
Now we have sample mean difference does not depend about the sample sizes.
This is because
E(X-Y) = E(X)-E(Y) for all X and Y
Mean of X-Y =
This does not depend on the specified sample sizes
B. The answer is the same irrespective of the sample sizes.
