Answer:
Labrador retrievers
Step-by-step explanation:
We know that the mean
is:

and the standard deviation
is:

The probability that a randomly selected Labrador retriever weighs less than 65 pounds is:

We calculate the Z-score for X =65

So

Looking in the table for the standard normal distribution we have to:
.
Finally the amount N of Labrador retrievers that weigh less than 65 pounds is:

Answer:
They must buy 501 pounds of produce for the membership to be worth it.
Step-by-step explanation:
You can solve this question by first finding the difference between $0.10 and $0.25.
With some simple subtraction (0.25-0.10) we can find that the difference is that a non-membership person would pay $0.15 per pound.
You then divide 75 by 0.15 to find the extra weight it would take for the produce to equal $75. You should get 500 pounds.
At 500 pounds, the price would be equal if you had a membership or not.
You then must add 1 pound to make it more favorable to have the membership.
At 501 pounds the person with the membership would pay $125.10 and the person without the membership would pay $125.25
