Answer: $32,732.58
Step-by-step explanation:
To calculate the total loan payment over the course of the loan period, use the future value formula:
= Loan amount * (1 + rate) ^ number of years
As this loan is compounded monthly, you need to convert certain terms to monthly figures:
Number of periods = 6 * 12 months = 72 months
Interest = 4.5 / 12 = 0.375%
Total payment:
= 25,000 * ( 1 + 0.375%)⁷²
= $32,732.58
Answer:
Step-by-step explanation:
We want to determine a 98% confidence interval to estimate the true mean shear strength of anchor bolts.
Number of sample, n = 78
Mean, u = 4.25
Standard deviation, s = 1.3
For a confidence level of 98%, the corresponding z value is 2.33.
We will apply the formula
Confidence interval
= mean ± z × standard deviation/√n
It becomes
4.25 ± 2.33 × 1.3/√78
= 4.25 ± 2.33 × 0.147
= 4.25 ± 0.34
The lower end of the confidence interval is 4.25 - 0.34 = 3.91
The upper end of the confidence interval is 4.25 + 0.34 = 4.59
b) the confidence interval would still be valid because the number of samples is large(> 30)

Answer:
415.48 or 132.25 pi cm
Step-by-step explanation:
23 divided by 2 is 11.5 so that is the radius. Then you multiply the radius by pi. Or you can do 11.5 x 11.5 if you are trying to find the solution without pi.
To find the distance b/t 2 points you need to use the distance formula. that is
distance = square root of (x2-x1)^2 + (y2-y1)^2
to fill it in, it is
(it doesnt matter which point you start with, as long as its consistent)
x1 = 9
x2 = 5
y1 = -8
y2 = -10
square root of (5-9)^2 + (-10-8)^2
lets do algebra!
square root of (-4)^2 + (-18)^2
square root of 16 + 324
square root of 340
Distance = 18.4391 units.
I hope this helps!
