The amount owed at the end of the 6 years duration is $10865
How to determine the amount owed in six years?The given parameters about the compound interest are
Principal Amount, P = $5300
Interest Rate, R = 8%
Time, t = 6 years
To calculate the amount owed, we make use of the following formula
A = P + CI
Where
Compound interest, CI = P(1 + R)^t - P
So, the equation becomes
A = P + P(1 + R)^t - P
Evaluate the like terms
A = P(1 + R)^t
In this question, the formula is given as
A = P(1 + r/n)^nt
Where
n = 12, i.e compounded monthly
Substitute the known values in the above equation
A = 5300 * (1 + 8%/12)^(6*12)
Express 8% as decimal
A = 5300 * (1 + 0.08/12)^(6*12)
Evaluate the sum
A = 5300 * (1.01)^(6*12)
Evaluate the exponent
A = 5300 * 2.05
Evaluate the product
A = 10865
Hence, the value of the amount after 6 years is $10865

You intend to estimate a population mean with a confidence interval. You believe the population to have a
normal distribution. Your sample size is 51.
Find the critical value that corresponds to a confidence level of 95%.
(Report answer accurate to three decimal places with appropriate rounding.)
The critical value will be +- 1.96.
What is critical value?
A crucial value delimits areas of a test statistic's sampling distribution. Both confidence intervals and hypothesis tests take these values into account.
Main body:
sample size is 10.
if you use z-scores, and it appears that you have to, since you don't know the mean or standard deviation of your population, your mean is 0 and your standard deviation is 1.
at 95% confidence level, 100% - 95% is your alpha.
that makes it equal to 5%.
divide that by 2 and you have half your alpha on the left end of the confidence interval and half on the right end.
that makes it 2.5% on each end.
2.5% is the same as .025 in decimal form.
look up a z-score to the left of .025 to get a z-score of -1.959963986 which can be rounded to -1.96.
since the normal distribution is symmetric about the mean,

function y = ².
1. vertex (0, 0), point (-2.3)
The graph of the quadratic function y = 0.75x² is given by the image at the end of the answer.
The notation y = 0.75x² is already in vertex form, meaning that the function was vertically compressed by a factor of 3/4 from the original graph.
How to define the quadratic equation?The definition of a quadratic equation with vertex (h,k) is given as follows:
y = a(x - h)² + k.
In which a represents the leading coefficient of the quadratic function.
In this problem the coordinates of the vertex are:
(0,0).
Hence the parameters are:
h = 0, k = 0.
Thus the equation is:
y = ax².
When x = -2, y = 3, hence the leading coefficient is given as follows:
3 = a(-2)²
4a = 3
a = 3/4
a = 0.75.
Hence the equation is:
y = 0.75x².
The multiplication by 0.75 means that the parent function y = x² is vertically compressed by a factor of 0.75.

The following is the 95% confidence interval for the standard deviation of UH students' height: CI = (1.81, 4.028) that is option B is correct.
What is standard deviation?The term "standard deviation" (or "") refers to a measurement of the data's dispersion from the mean. A low standard deviation indicates that the data are grouped around the mean, whereas a high standard deviation shows that the data are more dispersed. The standard deviation gauges how widely the data deviates from the mean. When comparing data sets that may have the same mean but a different range, it is helpful.
Here,
The formula for the standard deviation's confidence interval is given as CI = √[(n - 1)s²/(χ²ₙ ₋ ₁, α/2)], √[(n - 1)s²/(χ²ₙ ₋ ₁, (1 - α)/2)]
Number of participants; n = 14 D F = n - 1 = 14 - 1 = 13
Deviation from the mean; s = 2.5
Significant level; = 1 - 0.95 = 0.05
Confidence level; CL = 95% = 0.95
As a result, using an online Chi-square distribution table, we have:
χ²₁₃, ₀.₀₂₅ = 24.736
(χ²₁₃, ₀.₉₇₅) = 5.01
CI = √[(13 * 2.5²/(24.736)], √[(13 * 2.5²/(5.01)]
CI = (1.81, 4.03) (1.81, 4.03)

Matthew's curtain company is making curtains for a local hotel. he wants each curtain to be 36 inches long. at the fabric store, fabric is sold by the foot. if matthew's curtain company wants to make 74 curtains, how many feet of fabric will he need?
Matthew will need 222 feet of fabric to make 74 curtains.
According to the question,
We have the following information:
Required length of each curtain = 36 inches
Total number of curtains to be made = 74
Now, the total length of the fabric needed to make 4 curtains can be found by multiplying length of one curtain by total number of curtains.
So, we have the following expression:
36*74
2664 inches
Now, we will convert this into feet:
1 inch = 1/12 foot
2664 inches = 2664/12 feet
2664 inches = 222 feet
Hence, Matthew will need 222 feet of fabric to make 74 curtains.
