Nastasia [14]

Answer:

20.33%

Step-by-step explanation:

Principal = $2650

Total Interest = $300

Total amount = 42650+$300=$2950

Since we are given that You paid off the loan in 1 year by making 12 monthly payments

So, monthly payment = $\frac{2950}{12} =245.833$

Formula of monthly payment = $\text{Monthly payment }= \frac{Principal \times \frac{i}{12}}{1-(1+\frac{i}{12})^{-12}}$

where i is the rate of interest in decimals

To find i substitute the values

$245.833= \frac{2650 \times \frac{i}{12}}{1-(1+\frac{i}{12})^{-12}}$

using calculator

$i=0.2033$

So, rate of interest in percent = $0.2033 \times 100 = 20.33\%$

Thus the annual percentage rate (APR) is 20.33%

Archy [21]

Answer:

0.2916, 0.1488, 0.0319

Step-by-step explanation:

Given that a sign on the pumps at a gas station encourages customers to have their oil checked, and claims that one out of 10 cars needs to have oil added.

Since each trial is independent there is a constant probability for any random car to need oil is 0.10

Let X be the number of cars that need oil

A) Here X is BIN(4,0.1)

$P(X=1) = 4C1(0.1)(0.9)^3 \\= 0.2916$

B) Here X is Bin (8, 0.1)

$P(x=2) = 8C2 (0.1)^2 (0.9)^6\\\\=0.1488$

C) Here X is Bin (20,5)

$P(x=5) = 20C5 (0.1)^5 (0.9)^{15} \\=0.0319$
