Answer:

C

Step-by-step explanation:

First we find the z-score.

z = (x - μ) / σ

z = (520 - 500) / 60

z = 0.33

Using a calculator or z-score table:

P(z < 0.33) = 0.6293

The probability is approximately 63%.  Answer C

What is the product in lowest terms?

C 
because you would take 3/4 and multiply it by 3/3 to get the denominator to 12
and you would multiply 1/3 by 4/4 again to get the denominator to 12.
You are getting the denominator to 12 because 12 is 3 and 4s Most Common multiple!
Now that you have multiplied them you should have 9/12 and 4/12 
Then you subtract 4 from 9 to get 5.
So the answer is 5/12!

Let's split these two situations up.
Linda
Linda deposits $1,800 into an account that pays 7.5% interest, compounded.
The equation:
1,800× 1.075^x=y
Let's put in 10 for x.
1.075^10= 2.06103156 × 1,800= 3,709.85681≈ 3,710
Anna
Anna deposits $4,000 into an account that pays 5% interest, compounded.
The equation:
4,000× 1.05^x=y
Let's put in 10 for x.
1.05×10= 1.62889463×4,000= 6515.57852= 6516
A) Linda's account: $3,710
Anna's account: $6,516
