Find its price
Answers
a) The zero rates for the five maturities are: 1 year is 2.01%, 2 years is 2.48%, 3 years is 2.77%, 4 years is 1.73%, and 5 years is 4.32%.
b) The price of the security is $128.31.
a) To find the zero rates for all 5 maturities, we can use the formula for the present value of a bond:
PV = C / [tex](1+r)^n[/tex]
where PV is the present value,
C is the coupon payment,
r is the zero rate, and
n is the number of years to maturity.
We can solve for r by rearranging the formula:
r = [tex](C/PV)^{(1/n) }[/tex]- 1
Using the bond data given in the question, we can calculate the zero rates for each maturity as follows:
For the 1-year bond, PV = 98 and C = 0, so r = 2.01%.
For the 2-year bond, PV = 101, C = 2.48, and n = 2, so r = 2.48%.
For the 3-year bond, PV = 103, C = 2.91, and n = 3, so r = 2.77%.
For the 4-year bond, PV = 101, C = 2, and n = 4, so r = 1.73%.
For the 5-year bond, PV = 103, C = 5, and n = 5, so r = 4.32%.
Alternatively, we can use linear algebra to find the zero rates. We can write the present value equation in matrix form:
PV = A × x
where A is a matrix of coefficients, x is a vector of unknowns (the zero rates), and PV is a vector of present values.
To solve for x, we can use the equation:
x = ([tex]A^{-1}[/tex]) x PV
where ([tex]A^{-1}[/tex]) is the inverse of matrix A.
Using this method, we can solve for the zero rates as follows:
[2.01% ]
[2.48% ]
[2.77% ] = x
[1.73% ]
[4.32% ]
PV = [tex]A^{-1}[/tex] x [98]
[101]
[103]
[101]
[103]
PV = [-0.0201]
[ 0.0248]
[ 0.0277]
[-0.0173]
[ 0.0432]
b) To find the price of the security which pays cash flows of $10 in one year, $25 in two years, and $100 in four years, we can use the formula for the present value of a series of cash flows:
PV = [tex]C1/(1+r)^1 + C2/(1+r)^2 + C3/(1+r)^4[/tex]
where PV is the present value, C1, C2, and C3 are the cash flows, r is the zero rate, and the exponents correspond to the number of years until each cash flow is received.
Using the zero rates calculated in part (a), we can calculate the present value of each cash flow:
PV1 = $10 /(1+2.01 % [tex])^1[/tex] = $9.80
PV2 = $25/(1+2.48%[tex])^2[/tex] = $22.15
PV3 = $100/(1+1.73%[tex])^4[/tex] = $81.36
Then, the price of the security is the sum of the present values:
PV = $9.80 + $22.15 + $81.36 = $128.31
Therefore, the price of the security is $128.31.

The inverse function r(m), to find the radius of a sphere with mass, m is:
r(m) = ∛(3m/50π)
Determining the inverse function to determine radius of a sphereFrom the question, we are to determine the inverse function r(m), to find the radius of a sphere with mass, m
From the given information, we have that
m(r) = 50/3 πr³
This can be written as
m = 50/3 πr³
To determine the inversion function r(m), we will simply make r the subject of the above equation
m = 50/3 πr³
Multiply both sides of the equation by 3/50
3/50 × m = 3/50 × 50/3 πr³
3/50 × m = πr³
Divide both sides by π
3/50 × m/π = πr³/π
3/50 × m/π = r³
This can be written as
r³ = 3/50 × m/π
Take the cube root of both sides
r = ∛(3m/50π)

what is the probability that the largest among these random samples is greater than the population median?
Answers
The probability that the largest of n random samples is greater than the population median M is bounded above by[tex]1 - F(M)^(n-1) \times F(X(n))[/tex].
Assumptions about the population and the sampling method.
Let's assume that the population has a continuous probability distribution with a well-defined median, and that we are taking independent random samples from this population.
Let [tex]X1, X2, ..., Xn[/tex] be the random samples that we take from the population, where n is the sample size.
Let M be the population median.
The probability that the largest of these random samples, denoted by X(n), is greater than M.
Cumulative distribution function (CDF) of the population distribution to calculate this probability.
The CDF gives the probability that a random variable takes on a value less than or equal to a given number.
Let F(x) be the CDF of the population distribution.
Then, the probability that X(n) is greater than M is:
[tex]P(X(n) > M) = 1 - P(X(n) < = M)[/tex]
Since we are assuming that the samples are independent, the joint probability of the samples is the product of their individual probabilities:
[tex]P(X1 < = x1, X2 < = x2, ..., Xn < = xn) = P(X1 < = x1) \times P(X2 < = x2) \times ... \times P(Xn < = xn)[/tex]
For any x <= M, we have:
[tex]P(Xi < = x) < = P(Xi < = M) for i = 1, 2, ..., n[/tex]
Therefore,
[tex]P(X1 < = x, X2 < = x, ..., Xn < = x) < = P(X1 < = M, X2 < = M, ..., Xn < = M) = F(M)^n[/tex]
Using the complement rule and the fact that the samples are identically distributed, we get:
[tex]P(X(n) > M) = 1 - P(X(n) < = M)[/tex]
= [tex]1 - P(X1 < = M, X2 < = M, ..., X(n) < = M)[/tex]
=[tex]1 - [P(X1 < = M) \times P(X2 < = M) \times ... \times P(X(n-1) < = M) \times P(X(n) < = M)][/tex]
[tex]< = 1 - F(M)^(n-1) \times F(X(n))[/tex]
Probability depends on the sample size n and the distribution of the population.
If the population is symmetric around its median, the probability is 0.5 for any sample size.
As the sample size increases, the probability generally increases, but the rate of increase depends on the population distribution.

true or false: we conduct a test of hypothesis by assuming that ha is correct, since that is the hypothesis we are trying to show is true. group of answer choices true false
Answers
Given statement "We conduct a test of hypothesis by assuming that ha is correct, since that is the hypothesis we are trying to show is true." is true. Because we start by assuming that the null hypothesis is correct, not the alternative hypothesis, when conducting a test of the hypothesis.
When conducting a test of hypothesis, we do not assume that Ha (the alternative hypothesis) is correct.
Instead, we begin by assuming that the null hypothesis (H0) is true.
The null hypothesis typically represents a statement of "no effect" or "no difference" between two groups or variables.
The alternative hypothesis (Ha) represents the statement we are trying to prove or gather evidence for but we must start with the assumption that the null hypothesis is correct.
State the null hypothesis (H0) and the alternative hypothesis (Ha).
The null hypothesis typically represents the status quo or a baseline assumption, while the alternative hypothesis represents the claim you want to prove or gather evidence for.
Determine the level of significance (α), which is the probability of rejecting the null hypothesis when it is actually true. Common significance levels are 0.05, 0.01, and 0.001.
Select an appropriate test statistic, which depends on the type of data and the hypothesis being tested. Examples include the t-test, chi-square test, and ANOVA.
Collect data and calculate the value of the test statistic based on the data.
Compare the calculated test statistic value to the critical value for the chosen level of significance.
If the test statistic is more extreme than the critical value, we reject the null hypothesis in favor of the alternative hypothesis.
Otherwise, we fail to reject the null hypothesis.
Hence, the statement is false.

Determine the scale ratio for this map given that the distance from Wellspring to Red Creek is 4 inches on the map and 10 miles in reality.
Answers
The scale ratio for this map is 0.0000063.
What is scale ratio?
Scale ratio is the ratio between the measurements of an object or distance on a map or drawing and the actual measurements of the object or distance it represents in real life. It allows us to compare and relate the sizes or distances of objects in a drawing or map to their actual sizes or distances in the real world.
The scale ratio can be found by dividing the distance on the map by the corresponding distance in reality:
scale ratio = distance on map / distance in reality
In this case, the distance from Wellspring to Red Creek is 4 inches on the map and 10 miles in reality. So the scale ratio is:
scale ratio = 4 inches / 10 miles
To simplify this ratio, we need to convert the units so that they are the same. Let's convert inches to miles:
1 mile = 63,360 inches
So, we can convert the inches on the map to miles as follows:
4 inches * (1 mile / 63,360 inches) = 0.000063 miles
Now we can rewrite the scale ratio as:
scale ratio = 0.000063 miles / 10 miles
Simplifying this ratio by canceling out the units of miles, we get:
scale ratio = 0.0000063
Therefore, the scale ratio for this map is 0.0000063.

A primary credit cardholder's card has an APR of 22. 99%. The current monthly balance, before interest, is $4,528. 34. Determine how much more the cardholder will pay, making monthly payments of $200, until the balance is paid off, instead of paying off the current balance in full
Answers
The cardholder will pay an additional $1,471.66 in interest by making monthly payments of $200 until the balance is paid off instead of paying off the current balance in full.
First, we need to calculate the total interest that will accrue on the current balance of $4,528.34. We can do this using the formula
Interest = Balance x (APR/12)
where APR is the annual percentage rate and is divided by 12 to get the monthly interest rate. Plugging in the values, we get:
credit card Interest = $4,528.34 x (22.99%/12) = $87.80
So the total interest that will accrue on the current balance is $87.80.
Next, we need to calculate how long it will take to pay off the balance by making monthly payments of $200. We can use a credit card repayment calculator to do this, but we'll use a simplified formula here
Months = -log(1 - (Balance x (APR/12))/Payment) / log(1 + (APR/12))
where Payment is the monthly payment amount. Plugging in the values, we get
Months = -log(1 - ($4,528.34 x (22.99%/12))/$200) / log(1 + (22.99%/12)) = 29.6 months
So it will take about 30 months (or 2.5 years) to pay off the balance by making monthly payments of $200.
Finally, we can calculate how much more the cardholder will pay in total by subtracting the current balance from the total amount paid over 30 months
Total amount paid = $200 x 30 = $6,000
Total interest paid = $6,000 - $4,528.34 = $1,471.66

If you are given a sample percentage of 43%, you would need to know the sample size in order to convert this percentage to a proportion.
The conversion formula is proportion = percentage/100. However, the proportion alone does not give information about the sample size, which is necessary for inference and hypothesis testing. The other statements are not true.
The test statistic is not affected by the sample size, but its value can be used to determine the significance of a hypothesis test. A larger p-value indicates weaker evidence against the null hypothesis, not stronger evidence. Finally, we assume the null hypothesis is true until we have sufficient evidence to reject it.

The figure shown is a triangular prism. How much would it cost to cover the bases and the other three
faces with foil that costs $0.34 per square foot?
The foil will cost $

Answers
Thus, the cost to cover all three faces and base of the triangular prism is $12.24.
Explain about the triangular prism:An elongated pyramid-like 3D shape is a triangular prism. It features three rectangular faces and two bases. A form must have two similar bases, at least three rectangle-shaped faces, and a consistent cross-section over its whole length in order to qualify as a prism. Your shape is a triangular prism if it is also triangular.
Area of the rectangular base A1 = length * width
A1 : 5*2 = 10 ft²
Area of two rectangles faces A2:
A2: 2*3 + 2*4 = 14 ft²
Area of the two triangles faces A3 = 1/2*base*height
Base of triangle: (x)+(x-5)
Using the Pythagorean theorem:
x²+h² = 3²
h² = 9-x² ...eq 1
(5-x)²+h²=4²
h²=16-(5-x)² ...eq 2
Equating eq 1 and eq 2:
9-x² = 16-(5-x)²
9-x² = 16-25-10x-x²
on solving:
x=1.8
Then,
h²=9-(1.8)²------------ >
h=2.4 ft
Area A3 = (5*2.4)*2/2 = 12 ft²
Total Surface area A = A1+A2+A3
A = 10+14+12
A = 36 ft²
Rate of foil:
$0.34 for 1 ft²
For, A = 36 ft²
rate = 36*0.34
rate = $12.24
Thus, the cost to cover all three faces and base of the triangular prism is $12.24.

Determine the equation of the hyperbola with and co-vertices (1, 5) and (-7, 5) and
asymptotes y = x+8 and y = -x +2.
Answers
The equation of the hyperbola is [tex](x + 3)^2/16 - (y - 5)^2/36[/tex] = 1.
What is hyperbola?The collection of all points in a plane such that the distance between any point on the curve and two fixed points (referred to as the foci) is constant is known as a hyperbola. Hyperbolas are a sort of conic section. A hyperbola contains two distinct branches and has the appearance of two curving branches that are mirror reflections of one another. A hyperbola's center, vertices, co-vertices, foci, and asymptotes are some of its most important characteristics. The center, which is the point around which the hyperbola is symmetric, is the midway of the line segment connecting the vertices.
Given that, the co-vertices are (1, 5) and (-7, 5).
Now, using the midpoint formula we have:
center = ((1+(-7))/2, (5+5)/2) = (-3, 5)
Now, the distance between center and vertex is a = 4.
Also, the distance between the center and each co-vertex is b = 6.
Now, the equation of the hyperbola is:
[tex](x - (-3))^2/4^2 - (y - 5)^2/6^2 = 1\\(x + 3)^2/16 - (y - 5)^2/36 = 1[/tex]
Hence, the equation of the hyperbola is [tex](x + 3)^2/16 - (y - 5)^2/36[/tex] = 1.

Find the volume of this sphere using 3 for pie
Answers
The volume of this sphere is equal to 4,000 cm³.
How to calculate the volume of a sphere?In Mathematics and Geometry, the volume of a sphere can be calculated by using this mathematical equation (formula):
Volume of a sphere = 4/3 × πr³
Where:
r represents the radius.
Note: Radius = diameter/2 = 20/2 = 10 cm.
By substituting the given parameters into the formula for the volume of a sphere, we have the following;
Volume of a sphere = 4/3 × 3 × (10)³
Volume of a sphere = 4 × 1000
Volume of a sphere = 4,000 cm³

The volume of the basketball is approximately 4.2x³.
How to solve for the volumea. The formula for the volume of a sphere is:
V = (4/3)πr³
where r is the radius of the sphere. In this case, the radius is given as x, so we have:
V = (4/3)πx³ ≈ 4.2x³
Therefore, the volume of the basketball is approximately 4.2x³.
b. The volume of a cube is given by:
V = s³
where s is the length of one of its sides. Since the basketball touches all of the sides of the case, the length of one of its sides is equal to the diameter of the basketball plus the length of a side of the basketball. This is equal to 2x + 2x = 4x. Therefore, we have:
V = (4x)³ = 64x³
Therefore, the volume of the box is 64x³.
c. The volume of air in the box is equal to the volume of the box minus the volume of the basketball. We can substitute the formulas we obtained in parts (a) and (b) to get:
V_air = V_box - V_basketball = 64x³ - 4.2x³ = 59.8x³
Therefore, the volume of air in the box is approximately 59.8x³.
