Solve the problem using the formula below. given a note for $1,000, with 24 equal monthly payments, and a 7.5% true annual interest rate is charged. what is the principal plus interest payment? $

The usual formula for finding the amount A of a monthly payment on principal amount P with annual interest rate r over t years is

... A = Pr/(12·(1 -(1+r/12)^(-12t)))

Filling in P=1000, r=.075, t=2, you get

... A = 45.00

The montly payment is $45.00.

The given formula looks nothing like one used to compute the payment, nor is it anything like a formula used to compute interest on such a loan. We cannot figure out how to use it (or if it is even applicable) without knowing the definitions of the variables involved.

hello,

b) 62.47% of the students are between 14 and 18 years old.

step-by-step explanation:

mean = 15 and standard deviation = 2

student between 14 to 18

formula used z-score

for age 14 , z score

using z-table , p(z> -0.5)=0.3085

for age 18 , z score

using z-table , p(z< 1.5)=0.9332

p(-0.5< z< 1.5)=0.9332-0.3085 = 0.6247

thus, 62.47% of the students are between 14 and 18 years old.
