I REALLY NEED HELP!Courtney plans to buy a new car and determines she can budget $400 monthly for six years. Her bank is offering a 7.5% annual interest rate. What is the maximum car loan she can afford to stay within her budget?Use the formula, A = P[(1+r)^n-1]/r(1+r)^n where P is the monthly payment, r is the monthly rate, and n is the number of months.A. $19,873.45B. $21,000.50C. $23,134.61D. $27,425.75Financial institutions often offer lower auto loan rates for new cars than used ones. A local credit union advertises new car loans at 2.79% APR and used car loans at 3.29% both for up to 72 months.Tyresa wants to buy a car but doesn’t want to spend more than $350 a month for a maximum of four years. What is the maximum loan amount she can take out for a new car and a used car using the advertised rates?Use the formula, A = where P [(1+r)^n-1]/r(1+r)^2 is the monthly payment, r is the monthly rate, and n is the number of months. Show all of your steps.

A cylindrical container has a height of 24 inches. Currently, the container is filled with water to a height of 18 inches. A leakyfaucet drips into the container, causing the height of the water in the container to increase by 2 inches per hour. The equationbelow can be used to find t, the number of hours it would take to fill the container.18 + ?t = 24What number should be the coefficient of t?

Suppose you are to throw a dart at a circular dart board with radius 2 inches. Let (X, Y ) denote the point that you hit on the board (you can assume the board is centered at the origin (0, 0), and that the dart hits somewhere on the board uniformly at random). (a) Find the joint PDF of X and Y . (b) Find the marginal PDFs of X and Y . (c) Find the conditional PDFs fX|Y and fY |X. (d) Suppose that the “bulls eye” on the target consists of a small circle centered at the origin with radius 0.25. Explain how you would use one of these PDFs to compute the probability of a dart hitting the bulls eye. Find this probability an even easier way. (e) What is the probability that X > 1? (f) If you know that X = 1, what is the PDF of Y conditioned on this fact? What’s the probability that Y > 0.3 conditioned on this fact?

Consider the distribution of exam scores (graded from 0 to 100) for 78 students when 35 students got an A, 25 students got a B, and 18 students got a C. Complete parts (a) through (d) below.How many peaks would you expect for the distribution?A.There would probably be many peaks corresponding to the different exam scores that each student had.B.There would probably be no peaks. The distribution of grades always tends to be uniform.C.There would probably be three peaks, because even though each exam score could be anywhere between 0 and 100, the only grades received were A, B, and C.D.There would probably be one peak because there are no obvious reasons why the exam scores would form different groups.
