Answer:
Therefore, the approximate monthly payment is $548.85
Step-by-step explanation:
The amount of student loans Erica currently has = $34,006.00
The duration over which Erica is to pay back the loan = 7 years
The annual interest rate for the loan = 9.1%
Therefore, we have the geometric sequence formula is given as follows;
![A_n = P( 1 + r)^n - M \times \left [ \dfrac{(1 + r)^n-1}{r} \right ]](https://tex.z-dn.net/?f=A_n%20%3D%20P%28%201%20%2B%20r%29%5En%20-%20M%20%5Ctimes%20%5Cleft%20%5B%20%5Cdfrac%7B%281%20%2B%20r%29%5En-1%7D%7Br%7D%20%5Cright%20%5D)
Where;
M = The monthly payment
P = The initial loan balance = $34,006.00
r = The annual interest rate = 9.1%
n = The number of monthly payment = 7 × 12 = 84
Aₙ = The amount remaining= 0 at the end of the given time for payment
Substituting the values into the above formula, , we get;
![0 = 34006 \times \left ( 1 + \dfrac{0.091}{12} \right )^{84} - M \times \left [ \dfrac{\left (1 + \dfrac{0.091}{12} \right )^{84}-1}{\dfrac{0.091}{12} } \right ]](https://tex.z-dn.net/?f=0%20%3D%2034006%20%5Ctimes%20%5Cleft%20%28%201%20%2B%20%5Cdfrac%7B0.091%7D%7B12%7D%20%5Cright%20%29%5E%7B84%7D%20-%20M%20%5Ctimes%20%5Cleft%20%5B%20%5Cdfrac%7B%5Cleft%20%281%20%2B%20%5Cdfrac%7B0.091%7D%7B12%7D%20%5Cright%20%29%5E%7B84%7D-1%7D%7B%5Cdfrac%7B0.091%7D%7B12%7D%20%7D%20%5Cright%20%5D)
![M = \dfrac{34006 \times \left ( 1 + \dfrac{0.091}{12} \right )^{84} }{\left [ \dfrac{\left (1 + \dfrac{0.091}{12} \right )^{84}-1}{\dfrac{0.091}{12} } \right ]} \approx 548.85](https://tex.z-dn.net/?f=M%20%3D%20%5Cdfrac%7B34006%20%5Ctimes%20%5Cleft%20%28%201%20%2B%20%5Cdfrac%7B0.091%7D%7B12%7D%20%5Cright%20%29%5E%7B84%7D%20%20%7D%7B%5Cleft%20%5B%20%5Cdfrac%7B%5Cleft%20%281%20%2B%20%5Cdfrac%7B0.091%7D%7B12%7D%20%5Cright%20%29%5E%7B84%7D-1%7D%7B%5Cdfrac%7B0.091%7D%7B12%7D%20%7D%20%5Cright%20%5D%7D%20%5Capprox%20548.85)
Therefore, the approximate monthly payment = $548.85
Answer:
16% probability that the facility needs to recalibrate their machines.
Step-by-step explanation:
We have to use the Empirical Rule to solve this problem.
Empirical Rule:
The Empirical Rule states that, for a normally distributed random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviation of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
What is the probability that the facility needs to recalibrate their machines?
They will have to recalibrate if the number of defects is more than one standard deviation above the mean.
We know that by the Empirical Rule, 68% of the measures are within 1 standard deviation of the mean. The other 100-68 = 32% is more than 1 standard deviation from the mean. Since the normal distribution is symmetric, of those 32%, 16% are more than one standard deviation below the mean, and 16% are more than one standard deviation above the mean.
So there is a 16% probability that the facility needs to recalibrate their machines.

Step-by-step explanation: 9 small squares with one teddy bear in each, 4 medium squares with 4 bears in each medium square, and 1 big square for the entire thing.
The grade of a road is the slope of a road. In the U.S., grade is often expressed as a percent by finding the product 100(slope). Approximate the grade of a road that has a rise of 950 ft over 3 mi is :
A. 3%
A wall is in the shape of a trapezoid and it can be divided into a rectangle and a triangle. A triangle is with angles 45°- 45° - 90°. The hypotenuse of that triangle is 13√2 ft.Using the 45° - 45° - 90° theorem, sides of that triangle are in the proportion:x : x : x√2, and since that x√2 = 13√2 ( hypotenuse ), x = 13.Therefore h = 13 ft.We can check it: c² = 13² + 13²,c² = 169 + 169c² = 338c = √ 338 = 13√2Answer: h = 13 ft
