Answer:
D. $0.05
Step-by-step explanation:
Don't worry! I'll help you through it.
So we just have to find the unit rate (price) per apple.
$4 divided by 5lbs bag = $0.80 so, The 1st bag is $0.80 an apple.
$6 bag divided by 8lb = $0.75 an apple.
Now, simply subtract
0.80
-0.75
0.05
So your answer is D, $0.05
Have a great day!

Answer:
And if we solve for a we got
So the value of height that separates the bottom 20% of data from the top 80% is 23.432.
Step-by-step explanation:
Let X the random variable that represent the heights of a population, and for this case we know the distribution for X is given by:
Where
and
For this part we want to find a value a, such that we satisfy this condition:
(a)
(b)
As we can see on the figure attached the z value that satisfy the condition with 0.20 of the area on the left and 0.80 of the area on the right it's z=-0.842
If we use condition (b) from previous we have this:
But we know which value of z satisfy the previous equation so then we can do this:
And if we solve for a we got
So the value of height that separates the bottom 20% of data from the top 80% is 23.432.
