Q4 (15 points)
A borrowing sovereign has its output fluctuating following a uniform distribution U[16, 24]. Suppose that the government borrows L = 6 before the output is known; this loan carries an interest rate ri.
The loan is due after output is realized. 0.5 of its output.
Suppose that if the government defaults on the loan, then it faces a cost equivalent to c =
The loan is supplied by competitive foreign creditors who has access to funds from world capital markets, at a risk-free interest rate of 12.5%.
** Part a. (5 marks)
Find the equilibrium rī.
** Part b. (5 marks)
What is the probability that the government will repay its loan?
* Part c. (5 marks)
Would the borrowing country default if r = r? Prove it.
a. The equilibrium interest rate, is determined by the risk-free interest rate, the probability of repayment, and the cost of default.
b. The probability of the government repaying its loan can be calculated using the loan repayment threshold and the distribution of the output.
c. If the interest rate, r, is equal to or greater than the equilibrium interest rate, the borrowing country would default.
a. To find the equilibrium interest rate, we need to consider the risk-free interest rate, the probability of repayment, and the cost of default. The equilibrium interest rate is given by the formula: r = r + (c/p), where r is the risk-free interest rate, c is the cost of default, and p is the probability of repayment.
b. The probability that the government will repay its loan can be calculated by determining the percentage of the output distribution that exceeds the loan repayment threshold. Since 0.5 of the output is required to repay the loan, we need to calculate the probability that the output exceeds L/0.5.
c. If the interest rate, r, is equal to or greater than the equilibrium interest rate, the borrowing country would default. This can be proven by comparing the repayment threshold (L/0.5) with the loan repayment amount (L + Lr). If the repayment threshold is greater than the loan repayment amount, the borrowing country would default.
Calculations and further details would be required to provide specific numerical answers for each part of the question.

F. Compute A^1 + A^2 + ... + A^n where + is boolean addition (true/false)
The transitive closure by arithmetic operations on the adjacency matrix is Compute A⁰ + A¹ + ... + A⁽ⁿ⁻¹⁾ where + is standard addition (integers)
The transitive closure of a graph is the set of all possible paths from one vertex to another in the graph.
The best method to determine the transitive closure by arithmetic operations on the adjacency matrix is C.
Compute
=> A⁰ + A¹ + ... + A⁽ⁿ⁻¹⁾
where + is standard addition (integers).
The standard addition of integers is used because we are counting the number of paths between each vertex.
In this method, we start by computing A⁰, which is simply the adjacency matrix itself.
A¹ gives us the number of paths between each vertex that are one step long. A² gives us the number of paths between each vertex that are two steps long, and so on. We continue this process until we have computed
=> A⁽ⁿ⁻¹⁾
where n is the number of vertices in the graph.

The absolute maximum is -2 at x = 4, and the absolute minimum is -9 at x = -3.
To find the absolute extrema of f(x) on the interval [-3, 4), we need to first find the critical points and endpoints of the function. The critical points are the points where the derivative of the function is equal to 0 or undefined.
1. Find the derivative of f(x): f'(x) = 1
Since the derivative is a constant, there are no critical points.
2. Evaluate the function at the endpoints of the interval:
f(-3) = -3 - 6 = -9
f(4) = 4 - 6 = -2
3. Compare the values to determine the maximum and minimum:
The maximum value of f(x) on the interval is -2 at x = 4: f(4) = -2.
The minimum value of f(x) on the interval is -9 at x = -3: f(-3) = -9.

Find the critical value or values of based on the given information. H1: σ > 4.5 n = 19 = 0.05
The critical value for the given hypothesis test with a significance level of 0.05 and sample size of 19, testing the alternative hypothesis H1: σ > 4.5, cannot be determined without additional information.
To find the critical value, we need to know the distribution of the data and the desired level of significance (also known as the alpha level) for the hypothesis test. In this case, we are given that the significance level, denoted as alpha (α), is 0.05, but we do not have information about the distribution of the data or the desired level of significance.
The critical value is a value from the distribution that is used as a threshold to determine whether to reject or fail to reject the null hypothesis. If the test statistic (calculated from the sample data) is greater than the critical value, we would reject the null hypothesis in favor of the alternative hypothesis. If the test statistic is less than or equal to the critical value, we would fail to reject the null hypothesis.
However, without knowing the distribution of the data and the desired level of significance, we cannot determine the critical value for this hypothesis test. Therefore, we cannot provide a specific numerical value for the critical value in this case.
Therefore, the critical value for the given hypothesis test with a significance level of 0.05 and sample size of 19, testing the alternative hypothesis H1: σ > 4.5, cannot be determined without additional information.

Circles B, C , and D are all externally tangent to circle E, which has radius m/n , where m and nare relatively prime positive integers. Find m+n
For the given figure, where m and nare relatively prime positive integers. The value of m+n is 32.
Explain Law of Cosines.The law of cosines, also known as the law of cosines, relates all three sides of a triangle to one angle of the triangle. Most useful for searching for missing information in triangles. For example, if you know all three sides of a triangle, you can use the law of cosines to find the measure of the angle. Similarly, if you know two sides and the angle between them, you can find the length of the third side by the law of cosines.
Let X be the intersection of the circles with centers B and E, and Y be the intersection of the circles with centers C and E.
Since the radius of B is 3, AX = 4.
Assume AE = p.
Then EX and EY are radii of circle E and have length 4 + p.
AC = 8, and ∠CAE = 60° because we are given that triangle T is equilateral.
Using the Law of Cosines on Δ CAE, we obtain
(6+p)² =p² + 64 - 2(8)(p) cos 60
The 2 and the cos 60 terms cancel out:
p² + 12p + 36 = p² + 64 - 8p
12p+ 36 = 64 - 8p
p = 28/20
= 7/5
The radius of circle E is 4 + (7/5)
= 27/5,
So, the answer is 27 + 5 = 32

Bella invested $680 in an account paying an interest rate of 2 3/8% compounded
annually. Tanisha invested $680 in an account paying an interest rate of 2 7/8%
compounded quarterly. To the nearest hundredth of a year, how much longer would
it take for Bella's money to triple than for Tanisha's money to triple?
well, first off let's check on Bella, 2 and 3/8, that'd be a rate of 2.375%, well 680 tripled is simply 2040, so let's check
\(~~~~~~ \textit{Compound Interest Earned Amount} \\\\ A=P\left(1+\frac{r}{n}\right)^{nt} \quad \begin{cases} A=\textit{accumulated amount}\dotfill & \$2040\\ P=\textit{original amount deposited}\dotfill &\$680\\ r=rate\to 2.375\%\to \frac{2.375}{100}\dotfill &0.02375\\ n= \begin{array}{llll} \textit{times it compounds per year}\\ \textit{annually, thus once} \end{array}\dotfill &1\\ t=years \end{cases}\)
\(2040=680\left(1+\frac{0.02375}{1}\right)^{1\cdot t} \implies \cfrac{2040}{680}=1.02375^t\implies 3=1.02375^t \\\\\\ \log(3)=\log(1.02375^t)\implies \log(3)=t\log(1.02375) \\\\\\ \cfrac{\log(3)}{\log(1.02375)}=t\implies {\Large \begin{array}{llll} 46.805\approx t \end{array}}\)
now let's check on Tanisha, where 2 and 7/8 will be a rate of 2.875%, same tripled amount of 2040
\(~~~~~~ \textit{Compound Interest Earned Amount} \\\\ A=P\left(1+\frac{r}{n}\right)^{nt} \quad \begin{cases} A=\textit{accumulated amount}\dotfill & \$2040\\ P=\textit{original amount deposited}\dotfill &\$680\\ r=rate\to 2.875\%\to \frac{2.875}{100}\dotfill &0.02875\\ n= \begin{array}{llll} \textit{times it compounds per year}\\ \textit{quarterly, thus four} \end{array}\dotfill &4\\ t=years \end{cases}\)
\(2040=680\left(1+\frac{0.02875}{4}\right)^{4\cdot t} \implies \cfrac{2040}{680}=1.0071875^{4t}\implies 3=1.0071875^{4t} \\\\\\ \log(3)=\log(1.0071875^{4t})\implies \log(3)=t\log(1.0071875^4) \\\\\\ \cfrac{\log(3)}{\log(1.0071875^4)}=t\implies {\Large \begin{array}{llll} 38.350\approx t \end{array}} \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ \stackrel{Bella's}{46.805}~~ - ~~\stackrel{Tanisha's}{38.350} ~~ \approx ~~ 8.455~~ \approx ~~\text{\LARGE 8.46} ~~ \textit{about 8 years and 168 days}\)
If x+4/4 = y+7/7 then x/4 =___.
(Number 9 is the one I need an answer for)
Answer:
4th answer is correct
Step-by-step explanation:
First, let us make x the subject.
\(\sf \frac{x+4}{4} =\frac{y+7}{7}\)
Use cross multiplication.
\(\sf 7(x+4)=4(y+7)\)
Solve the brackets.
\(\sf 7x+28=4y+28\)
Subtract 28 from both sides.
\(\sf 7x=4y+28-28\\\\\sf7x=4y\)
Divide both sides by 7.
\(\sf x=\frac{4y}{7}\)
Now let us find the value of x/4.
To find that, replace x with (4y/7).
Let us find it now.
\(\sf \frac{x}{4} =\frac{\frac{4y}{7} }{4} \\\\\sf \frac{x}{4} =\frac{4y}{7}*\frac{1}{4} \\\\\sf \frac{x}{4} =\frac{4y}{28}\\\\\sf \frac{x}{4} =\frac{y}{7}\)
