A is $490 and B is 3990
Step-by-step explanation:
The way I solved this is with my last brain cells, you welcome.
So, if I'm understanding you correctly, f(x)=x^2 divided by 3x+x, or
f(x) = (x^2)/(3x+x)
f(6) --> plug the 6 in to all values of x --> f(6) = (6^2)/(3×6 + 6) = 36/(18+6)
= 36/24 --> both are divisible by 12, so 36/12=3 and 24/12=2, now we have the reduced (simplified) answer:
f(6) = 3/2, or 1 1/2, or 1.5
We have been given that the standard deviation of a group of 20 scores is 15 and we are asked to find variance.
Since we know variance is square of standard deviation. In order to find out the variance of the given data we have to take the square of 15.

Therefore, our variance is 225.
Answer:
17 is the answer
Step-by-step explanation:
The person that might want to claim exemption on the W-4 form is John who received money from his internship.
<h3>When can you claim the exemption when filling out the W-4 form?</h3>
