Present Value of Annuity = $4,000 × 26.1948 = $104779.2
What is a present value?
The worth of an anticipated revenue stream assessed as of the valuation date is known as the present value in the fields of economics and finance.
Here, we have
Where , Annuity Amount = $4,000
n = No. of periods = 8 years × 4 quarters per year = 32 periods but since the first payment is at beginning of the quarter,
Then, n = 31 when considered for PVAF
r = 5.4% / 4 quarters = 1.35%,
Present value of Annuity = Annuity Amount × Present Value Annuity Factor i.e. PVAF (n, r)
PVAF(n₀,r) when the first payment is at beginning of n i.e.
n₀ = 1 + { [1-(1+r)^ -n ]/r }
= 1 + { [1-(1+0.0135)^ {-31}]/0.0135 }
= 1 + [ (1 - 0.65987 ) ] / 0.0135]
= 1 + 25.1948
= 26.1948
PVAF(32,35%) = 26.1948
Hence, Present Value of Annuity = $4,000 × 26.1948 = $104779.2

A market research company wishes to know how many energy drinks teenagers drink each week. They want to construct a 80% confidence interval with an error of no more than 0.06. A consultant has informed them that a previous study found the mean to be 5.7 energy drinks per week and found the standard deviation to be 0.9. What is the minimum sample size required to create the specified confidence interval? Round your answer up to the next integer.
The minimum sample size required is 108.
What is the standard deviation?
A standard deviation (or σ) is a measure of how dispersed the data is in relation to the mean. A low standard deviation means data are clustered around the mean, and a high standard deviation indicates data are more spread out.
To find the minimum sample size required, we can use the formula for the margin of error for a confidence interval for a mean:
margin of error = (z*s) / (√n)
where z is the z-score corresponding to the desired confidence level (in this case, z = 1.28 for an 80% confidence interval), s is the standard deviation of the population, and n is the sample size.
We are given that the margin of error should be no more than 0.06 and that the standard deviation is 0.9. We can solve for n by rearranging the formula and substituting in the given values:
n = [(zs) / margin of error]²
= [(1.280.9) / 0.06]²
= approximately 107.5
Since the sample size must be an integer, we must round up to the next integer, which is 108.
Hence, the minimum sample size required is 108.

What is the law of cosines?
The square of a side of a plane triangle is equal to the sum of the squares of the other sides minus twice the product of those sides and the cosine of the angle between them, according to a trigonometry rule.
Here, we have
This line is 300 mi long and makes an angle of 40° from the horizontal (based on N50°E bearing).
From point A draw a horizontal line to point C. This line=(35/60)*250=145.8 mi.
Draw a line connecting point C to point B. You now have a triangle with sides AB = 300 mi and AC = 145.8 mi and their included angle of 40.
Using the Law of cosines to find CB:
(CB)² = (AB)²+(AC)² -2*AB*AC*cos 40°
(CB)² = (300)²+(145.8)²-2*300*145.8*cos 40°
(CB)² = 90000+21257 - 46928 = 64329

If a sample consists of 600 test scores, 516 of them would be at or below the 86th percentile. If a sample consists of 600 test scores, 228 of them would be at or above the 62th percentile.
What is percentile?A percentile is a score that compares a specific score to the scores of the other members of a group. It displays the proportion of other scores that a given score outperformed. For instance, if you have a test score of 75 and are placed in the 85th percentile, it signifies that your score is greater than those of 85% of other test takers.
Given that,
In general, 70 % of the values in a data set lie at or below the 70th percentile.
20 % of the values in a data set lie at or above the 20th percentile.
Generally percentile defines the percentage of a data set that is below or at a value that is being considered.
Hence the percentage of the values of a data set that lies below or at the 16th percentile is 16%
Also the values of a data set that lies below or at the 24th percentile is 24%
Given a sample of 600 test scores , the number of test scores that will be at or below the 86th percentile is 86% of 600 which is mathematically represented as:
K = [tex]\frac{86}{100}[/tex] × 600
K = 516 test scores
Given a sample of 600 test scores , the number number of test scores that will be above the 62 th percentile is (100 - 62 = 38 )% of 600 which is mathematically represented as:

A collection of coins consists of nickels, dimes and quarters. There are three fewer quarters than nickels and six more dimes than quarters. How many of each kind of coin are in the collection if the total value of the collection is $4.35
Answer:
There are 12 nickels, 9 quarters, and 15 dimes.
I hope this turns out useful for you!
Step-by-step explanation:
Reading the problem repeatedly, I found that the nickels were the value that I could change to find out the values of the other coins and to find the answer. I started with the number of nickels as 20, calculating 20 x 5 (5 as the value of the nickel) = 100 ($1.00). Then, I subtracted three from 20 since the number of quarters was 3 less and got 17. 17 x 25 = a value far too big when we were going to add dimes as well, so 8 lowered the number of nickels a reasonable amount and tried again, following the directions in the problem. It took a bit, but I found a value that worked.
Nickel = $0.05
Quarter = $0.25
Dime = $0.10
My work (though I converted a bit using my sense of money)
12 x 5 = $0.60
12 - 3 = 9
9 x 25 = $2.25
9 + 6 = 15
15 x 10 = $1.50
$0.60 + $2.25 + $1.50 = $4.35

A soft drink can has a height of 16cm and a radius of 3cm. Find L, the length of the longest straw that can fit into the can (so that the straw is not bent and fits entirely inside the can). Give your answer rounded DOWN to the nearest cm, to ensure it fits inside the can.
In linear equation, 16.27 is the length of the longest straw that can fit into the can (so that the straw is not bent and fits entirely inside the can).
Describe a linear equation using an example.
An equation in which there is only one variable is known as a linear equation in one variable. It has the mathematical formula Ax + B = 0, where A and B can be any two real numbers, and x is an unknowable variable with just one possible value.
A linear equation in one variable would be 9x + 78 = 18, for instance.
l² = r² + h²
l² = 3² + 16²
l² = 9 + 256
= 265
l = √265
l = 16.27

What is a function ?
A relationship between a group of inputs and one output each is referred to as a function. In plain English, a function is an association between inputs in which each input is connected to precisely one output. A domain, codomain, or range exists for every function.
See if any vertical lines that were drawn touch the curve more than once by carefully examining the graph. The graph does not represent a function if there is any such line. The graph does reflect a function if no vertical line can cross the curve more than once.
The domain of function are set of values of x for which the function covers.
For the given function, from the graph the function starts from x =-1 and ends at x = 0.
So, the domain of the function are all real numbers between -1 and 0.

Answer:
b) 7
Step-by-step explanation:
Given equation:
[tex](\sin x + \csc x)^2+(\cos x + \sec x)^2=k+\tan^2 x + \cot^2 x[/tex]
Expand the left side of the equation:
[tex]\implies \sin^2x+2 \sin x \csc x + \csc^2x + \cos^2 x + 2 \cos x \sec x + \sec^2 x[/tex]
Simplify:
[tex]\implies \sin^2x+2 \sin x \cdot \dfrac{1}{\sin x} + \csc^2x + \cos^2 x + 2 \cos x \cdot \dfrac{1}{\cos x} + \sec^2 x[/tex]
[tex]\implies \sin^2x+2 + \csc^2x + \cos^2 x + 2 + \sec^2 x[/tex]
[tex]\implies \sec^2 x+\csc^2x+ \sin^2x + \cos^2 x +4[/tex]
Use the identity: sin²x + cos²x = 1
[tex]\implies \sec^2 x+ \csc^2x+1+4[/tex]
[tex]\implies \sec^2 x+ \csc^2x+5[/tex]
Use the identities: sec²x = tan²x + 1 and csc²x = cot²x + 1
[tex]\implies \tan^2x +1 +\cot^2x +1 +5[/tex]
[tex]\implies 7+\tan^2x + \cot^2x[/tex]
Therefore:
[tex](\sin x + \csc x)^2+(\cos x + \sec x)^2=7+\tan^2 x + \cot^2 x[/tex]

What is an isosceles triangle?In Mathematics, an isosceles triangle can be defined as a type of triangle that has two (2) of its sides equal in length and two (2) equal angles. This ultimately implies that, an isosceles triangle comprises two (2) angles and two (2) side lengths that have the same measure or are equal in magnitude.
In every isosceles triangle such as triangle PQR (ΔPQR), both the median and altitude are the same and they will lie on the same line segment when drawn from the top to the base in accordance with the Isosceles Triangle Theorem.
In conclusion, we can logically deduce that the vertex that runs from point T to point S is a perpendicular bisector that bisects line PQ into two (2) equal halves.
