Consider a student loan of $17 comma 500 at a fixed APR of 9% for 15 years.

Andrews [41]

Answer:

a) monthly payment: $177.50

b) total amount paid: $31,950

c) toward principal: $17,500; toward interest: $14,450

Step-by-step explanation:

a) The amount of the monthly payment (A) is computed from the principal (P), the annual interest rate (r) and the number of years (n) using the formula ...

A = P·(r/12)/(1 -(1 +r/12)^(-12n))

Filling in your numbers, we can use r/12 = 0.09/12 = 0.0075, and 12n = 12·15 = 180:

A = $17500·0.0075/(1 - 1.0075^-180) ≈ $177.50

b) The total payment over the term of the loan is 180 of these monthly payments:

180·$177.50 = $31,950

c) $17,500 is paid toward the principal.

$14,450 is paid toward interest.

Use the data in the table to answer the question. Citations are "speeding tickets." You may fill in the table to help you answer

Firlakuza [10]

Answer: ŷ = 0.07X + 5.2

Step-by-step explanation:

Given the following :

Number of citations 5 - 7.5 - 10 - 15 - 20

Outputs Residuals 3 - - 6 - - 10 - 5 - - 6

Using the online regression calculator :

Line of best fit is represented by the equation:

ŷ = 0.06897X + 5.2069

ŷ = 0.07X + 5.2

From the line equation:

y = mx + c

With 0.07 = slope of gradient(m)

Intercept (c) = 5.2 (point where the line of best fit intersect the y_axis

x and y are values of x and y respectively
