Answer:
15000(1.003425)^12t ;
4.11%
4.188%
Step-by-step explanation:
Given that:
Loan amount = principal = $15000
Interest rate, r = 4.11% = 0.0411
n = number of times compounded per period, monthly = 12 (number of months in a year)
Total amount, F owed, after t years in college ;
F(t) = P(1 + r/n)^nt
F(t) = 15000(1 + 0.0411/12)^12t
F(t) = 15000(1.003425)^12t
2.) The annual percentage rate is the interest rate without compounding = 4.11%
3.)
The APY
APY = (1 + APR/n)^n - 1
APY = (1 + 0.0411/12)^12 - 1
APY = (1.003425)^12 - 1
APY = 1.04188 - 1
APY = 0.04188
APY = 0.04188 * 100% = 4.188%

Answer:
x = 2.56, y = -2.63
Step-by-step explanation:
I first multiplied the second equation by two, getting
4x-6y = 26
I then subtracted the equations
4x+2y = 5
- 4x-6y = 26
--------------------
8y = -21
y = -2.63
with y solved, I plugged it into the second equation to get x:
2x-3(-2.63) = 13
2x+ 7.89 = 13
2x = 5.11
x = 2.56
I hope this helped! ;D
z statistic or z score can be calculated using the
following formula:
z = (x – u) / (σ / sqrt n)
So simply substitute the given values:
z = (120.4 – 115) / (30 / sqrt 25)
z = 0.90
