Answer:
y = (x + 1) - 4
Step-by-step explanation:
Vertex Form: y = a(x-h)^2 + k
First, we need to find the parent function. The parent function is (0,0)
Then we need to find where the parabola moved. WE don't need to look at the curved line, we just need to focus on the vertex. We see that the vertex is (-1,-4) Which means the vertex moved one unit towards the left and went down 4 units.
Now it is time to make the actual equation. First, we start with y=
y =
Now we need to put in the (x - h)^2. We see that the graph moved one unit towards the left, so we plug it in with h. Also, keep in mind, the graph isn't being stretched vertically, so the term is 1.
y = 1(x -- 1)^2 = 1(x + 1)^2
Now we need to find the k. The k term is how the graph changed by the y axis. Since it moved down 4 units. We can plug in -4.
y = 1(x + 1) + (-4) = 1(x + 1)^2 - 4
Our final answer is:
y = 1(x + 1) - 4

A vending machine that dispenses coffee into cups must fill the cups with 7.8 ounces of liquid. Before selling the machine to a college or business, the company tests the machine to be sure it dispenses an average of 7.8 ounces. A sample of 20 amounts is listed here:
7.78 7.79 7.82 7.82 7.87 7.84 7.80 7.82 7.80 7.78
7.83 7.75 7.85 7.83 7.84 7.73 7.82 7.87 7.81 7.88
(1) Set up the null and the alternative hypotheses to test whether the average amount of coffee dispensed is different from 7.8 ounces.
(2) Complete the remaining hypothesis-testing steps using α= .05.
(3) Find the p value.
(4) Based on the p value what can the company conclude about the average amount of coffee dispensed by the machine.
Answers
The null hypothesis states that the average amount of coffee dispensed by the machine is equal to 7.8 ounces, while the alternative hypothesis states that the average amount is different from 7.8 ounces.
In this scenario, the null hypothesis (H0) is that the average amount of coffee dispensed by the machine is 7.8 ounces, while the alternative hypothesis (Ha) is that the average amount differs from 7.8 ounces. To test these hypotheses, the next step is to calculate the test statistic.
Using the given sample of 20 amounts, we can compute the mean of the sample, which is 7.816 ounces. The standard deviation of the sample is 0.044 ounces. With these values, we can calculate the t-test statistic.
The t-test statistic is calculated by subtracting the hypothesized value (7.8) from the sample mean (7.816) and dividing it by the standard deviation (0.044), multiplied by the square root of the sample size (20). The resulting t-value is approximately 1.818.
To determine the p-value associated with this t-value, we compare it to the t-distribution with n-1 degrees of freedom (19 degrees of freedom in this case). Using a statistical table or software, we find that the p-value is approximately 0.085.
Since the p-value (0.085) is greater than the significance level (α = 0.05), we fail to reject the null hypothesis. This means that there is insufficient evidence to conclude that the average amount of coffee dispensed by the machine is different from 7.8 ounces. Therefore, based on the p-value, the company cannot conclude that the average amount of coffee dispensed is significantly different from 7.8 ounces.

Answer:
The students rented 3 small cars and 6 large cars.
Step-by-step explanation:
Since a group of college students are going to a lake house for the weekend and plan on renting small cars and large cars to make the trip, and each small car can hold 4 people and each large car can hold 6 people, and the students rented twice as many large cars as small cars, which altogether can hold 48 people, to determine the number of small cars rented, X, and the number of large cars rented, Y, the following calculation must be performed:
4X + 6Y = 48
4x4 + 6x8 = 16 + 48 = 64
4x3 + 6x6 = 12 + 36 = 48
Thus, the students rented 3 small cars and 6 large cars.

P(X = 1) = [tex]5C1(0.4)^1(1-0.4)^5^-^1[/tex] = 0.0026
P(X= 2) =[tex]5C2(0.4)^2(1-0.4)^5^-^2[/tex] = 0.0109
P(X [tex]\leq[/tex] 2) = P(X=1) + P(X=2)

n a contingency table, when all the expected frequencies are equal the oberved frequencies the calculaed chi squared statistic equals zero. True or False
Answers
The given statement "When all the expected frequencies are equal the observed frequencies the calculated chi squared statistic equals zero." is true because chi-squared statistic will be zero in this case.
In a contingency table, the expected frequencies are calculated based on certain assumptions and can be different from the observed frequencies. The chi-squared statistic is used to determine whether there is a significant association between the variables in the contingency table.
When all the expected frequencies are equal to the observed frequencies, it means that there is a perfect match between the observed data and what would be expected under the assumption of independence.
In this case, the chi-squared statistic will be zero, indicating no discrepancy between the observed and expected frequencies.
This scenario is highly unlikely to occur in real-world data because observed frequencies typically deviate from the expected frequencies due to sampling variability or factors influencing the relationship between variables.
In most cases, the expected frequencies will differ from the observed frequencies, resulting in a non-zero chi-squared statistic, indicating a significant association or departure from independence between the variables.

Answers
Answer:
I guess we have the table:
x f(x)
-4 7
-2 5
0 3
2 1
4 - 1
To find the slope of this, we need to select two different points (x1, y1) and (x2, y2) and use the relation:
slope = (y2 - y1)/(x2 - x1)
let´s use the first two:
(-4,7) and (-2, 5)
Slope = (5 - 7)/(-2 - (-4)) = -2/2 = -1
Now, if we want to be sure that this is a linear equation, we should do the same for other two pairs of points, now use the first and the third:
(-4, 7) and (0,3)
S = (3 - 7)/(0 -(-4)) = -4/4 = -1
Now, for the function g(x) we can see a constant line, that is parallel to the x-axis.
This means that the slope of this function is equal to zero.
This means that the slope of g(x) is bigger than the slope of f(x), because 0 > 1 i guess

Solve the integral equation, using convolution properties and Laplace transform, y (t) + et (t)e-dr=tet ? Given Answer: B. y(t) = et - 1 Correct Answer: B. y(t) = et - 1 QUESTION 4: MULTIPLE CHOICE 10 out of 10 points Use the convolution theorem to find the inverse Laplace transform 1 (s2+4)2 Given Answer: 3. sin(2t) – 2t cos(2t)/16 Correct Answer: 3. sin(2t) - 2t cos(2t)/16.
Answers
The Laplace transform is L{y(t)} = Y(s), [tex]L{e^t} = 1/(s-1), L{t*e^t} = -d/ds(1/(s-1))[/tex]
The inverse Laplace transform of [tex]1/(s^2+4)[/tex] is sin(2t)/2.
To solve the integral equation using convolution properties and Laplace transform, we can follow these steps:
Take the Laplace transform of both sides of the equation. Let Y(s) be the Laplace transform of y(t), and F(s) be the Laplace transform of f(t).
[tex]L{y(t)} = Y(s), L{e^t} = 1/(s-1), L{t*e^t} = -d/ds(1/(s-1))[/tex]
Apply the convolution property of Laplace transforms, which states that the Laplace transform of the convolution of two functions is equal to the product of their individual Laplace transforms.
Y(s) = F(s) * (1/(s-1)) - d/ds[F(s) * (1/(s-1))]
Substitute the given function [tex]F(s) = 1/(s^2+4)[/tex] into the equation.
[tex]Y(s) = (1/(s^2+4)) * (1/(s-1)) - d/ds[(1/(s^2+4)) * (1/(s-1))][/tex]
Simplify and find the inverse Laplace transform of Y(s) to obtain y(t).
Without the exact form of F(s), it is difficult to provide the specific calculations. However, based on the given answers, it seems that the correct answer is option B: [tex]y(t) = e^t - 1.[/tex]
For the second question, to find the inverse Laplace transform of [tex]1/(s^2+4)^2,[/tex] we can use the convolution theorem. The convolution theorem states that the inverse Laplace transform of the product of two Laplace transforms is equal to the convolution of their inverse Laplace transforms.
[tex]1/(s^2+4)^2 = L^{-1}{L{sin(2t)}/16 * L{2t*cos(2t)}/16}[/tex]
The inverse Laplace transform of [tex]1/(s^2+4) is sin(2t)/2.[/tex] The inverse Laplace transform of 1/s is 1.
Therefore, the inverse Laplace transform of [tex]1/(s^2+4)^2 is (1/16) * (sin(2t)/2 * 1) = sin(2t)/32.[/tex]
Based on the given answers, the correct answer is indeed option 3: sin(2t) - 2t*cos(2t)/16.

1. Prove that at any party of 31 people, there’s always a person who knows an even number of others. (Assume that acquaintance is mutual: if Alice knows Zelda, then Zelda knows Alice.)
Answers
To prove that at any party of 31 people, there's always a person who knows an even number of others, we can use the pigeonhole principle.
The pigeonhole principle states that if we distribute more than "n" objects into "n" boxes, then at least one box must contain more than one object. In this case, the "objects" represent the people at the party, and the "boxes" represent the number of people each person knows.
Let's assume, for the sake of contradiction, that every person at the party knows an odd number of others. This means that each person has an odd number of acquaintances.
Now, let's consider the sum of the number of acquaintances for all 31 people. Since each person knows an odd number of others, the sum of odd numbers is also an odd number.
However, if we count the total number of acquaintances in a group, it must be even since each acquaintance involves two people. This creates a contradiction because we cannot have both an odd and an even sum for the total number of acquaintances.
Therefore, our assumption that every person knows an odd number of others must be false. Hence, there must be at least one person at the party who knows an even number of others.

Answers
The value of Milton Industries with leverage is $131.52 million.
Milton Industries expects free cash flows of $20 million each year.
Milton's corporate tax rate is 22%, and its unlevered cost of capital is 16%.
Milton also has outstanding debt of $26.48 million and it expects to maintain this level of debt permanently.
a. Value of Milton Industries without leverage: Formula to calculate the value of a firm without leverage is; VL = VU + (PV of Tax shield) Where, VL = Value of the firm with leverage VU = Value of the firm without leverage PV of Tax Shield = Present Value of Tax Shield Expected Free Cashflows of Milton Industries = FCF = $20 million
Corporate Tax rate = T = 22%Unlevered
Cost of Capital = Ku = 16%Debt of Milton Industries = D = $26.48 million
Weighted Average Cost of Capital = WACC = Ku (1 - T)PV of Tax Shield = D x T x (1 - T) = $6.52 million VL = VU + PV of Tax Shield VU = FCF / Ku = $125 million VL = $125 + $6.52 = $131.52 million
b. Value of Milton Industries with leverage: VL = VU + PV of Tax Shield PV of Tax Shield = D x T x (1 - T) = $6.52 million VL = VU + PV of Tax Shield VU = FCF / Ku = $125 million VL = VU + PV of Tax Shield = $125 + $6.52 = $131.52 million. Therefore, The value of Milton Industries without leverage is $125 million. The value of Milton Industries with leverage is $131.52 million.
