(1) F(s) = 5+1 / (s^2 + 28s + 2)
To perform partial fraction expansion, we first need to factor the denominator:
s^2 + 28s + 2 = (s + 14 - sqrt(194))(s + 14 + sqrt(194))
We can then write:
F(s) = A / (s + 14 - sqrt(194)) + B / (s + 14 + sqrt(194))
where A and B are constants to be determined.
Multiplying both sides by the denominator and simplifying, we get:
5+1 = A(s + 14 + sqrt(194)) + B(s + 14 - sqrt(194))
Setting s = -14 - sqrt(194), we get:
5+1 = B(2sqrt(194))
Solving for B, we get:
B = (5+1) / (2sqrt(194))
Setting s = -14 + sqrt(194), we get:
5+1 = A(2sqrt(194))
Solving for A, we get:
A = (5+1) / (2sqrt(194))
Thus, the partial fraction expansion of F(s) is:
F(s) = [(5+1) / (2sqrt(194))] / (s + 14 + sqrt(194)) + [(5+1) / (2sqrt(194))] / (s + 14 - sqrt(194))
To find the inverse Laplace transform, we can use the table of Laplace transforms or MATLAB. Using MATLAB, we get:
ilaplace(F(s)) = (5+1) / (2sqrt(194)) * (exp(-14t) / sqrt(194)) * (cosh(sqrt(194)t) + sinh(sqrt(194)t))
(2) F(s) = s^2 + 3s + 1 / (s + 2)(s^2 + 8s + 1)
To perform partial fraction expansion, we first need to factor the denominator:
s^2 + 8s + 1 = (s + 4 - sqrt(15))(s + 4 + sqrt(15))
We can then write:
F(s) = A / (s + 2) + B / (s + 4 - sqrt(15)) + C / (s + 4 + sqrt(15))
where A, B, and C are constants to be determined.
Multiplying both sides by the denominator and simplifying, we get:
s^2 + 3s + 1 = A(s + 4 - sqrt(15))(s + 4 + sqrt(15)) + B(s + 2)(s + 4 + sqrt(15)) + C(s + 2)(s + 4 - sqrt(15))
Setting s = -4 + sqrt(15), we get:
-4 + sqrt(15) = A(-4 + sqrt(15) + 4 + sqrt(15))
Solving for A, we get:
A = (-4 + sqrt(15)) / (2sqrt(15))
Setting s = -4 - sqrt(15), we get:
-4 - sqrt(15) = A(-4 - sqrt(15) + 4 + sqrt(15))
Solving for A, we get:
A = (-4 - sqrt(15)) / (-2sqrt(15))
Setting s = -2, we get:
-1 = B(-2)(-2 + 4 + sqrt(15))
Solving for B, we get:
B = (-1) / (2sqrt(15) + 4)
Setting s =

A financial education time of 34 hours is found to result in an amount of debt of 34215 dollars. What is the predicted amount of debt?
A financial education time of 24 hours is found to result in an amount of debt of 38000 dollars. What is the predicted amount of debt?
The predicted amount of debt for a financial education time of 34 hours is $26,350.
The predicted amount of debt for a financial education time of 24 hours is $31,550.
For the given information, we need to know the regression equation that relates financial education time and amount of debt to predict the amount of debt for different time durations.
Assuming a linear relationship between financial education time and amount of debt, we can estimate the regression equation as:
Amount of Debt = a + b × Financial Education Time + Errorwhere a and b are the intercept and slope of the regression line, respectively, and Error is the random error term.
Using the given data points, we can estimate the regression line as:
Amount of Debt = 41500 - 450 × Financial Education Time(a) For a financial education time of 34 hours:
Amount of Debt = 41500 - 450 × 34 = $26,350Therefore, the predicted amount of debt for a financial education time of 34 hours is $26,350.
(b) For a financial education time of 24 hours:
Amount of Debt = 41500 - 450 × 24 = $31,550Therefore, the predicted amount of debt for a financial education time of 24 hours is $31,550.

Let X1, X2, ... be IID with mean . Let So O and Sn {k=1 Xk. Let T be a bounded stopping time for the filtration En 0{X1, ..., Xn}. Prove that E[ST] = uE[T]: First show Sk – ku is a martingale. = (Sr] = EL
To show that Sk - ku is a martingale, we need to show that it satisfies the two properties of a martingale:
Sk - ku is integrable for all k.
For any k, E[Sk+1 - ku+1 | E0,...,Ek] = Sk - ku.
First, we show that Sk - ku is integrable for all k:
E[|Sk - ku|] = E[|(X1 + ... + Xk) - k|]
= E[|X1 + ... + Xk| - k] (using linearity of expectation)
≤ E[|X1| + ... + |Xk|] + k (by triangle inequality)
= kE[|X1|] + ... + kE[|Xk|] + k (using linearity of expectation)
= kE[|X1|] + ... + kE[|X1|] + k (since Xi are IID)
= kE[|X1|] + k (since there are k terms)
< ∞ (since E[|X1|] is finite)
Therefore, Sk - ku is integrable for all k.
Next, we show that for any k, E[Sk+1 - ku+1 | E0,...,Ek] = Sk - ku:
E[Sk+1 - ku+1 | E0,...,Ek] = E[(X1 + ... + Xk+1) - (k+1) | E0,...,Ek]
= E[(X1 + ... + Xk) + Xk+1 - (k+1) | E0,...,Ek]
= E[(X1 + ... + Xk) - k | E0,...,Ek] + E[Xk+1 | E0,...,Ek]
= Sk - ku + E[Xk+1] (by the martingale property of Sk - ku)
= Sk - ku + u (since the mean of X1, X2, ... is u)
Therefore, Sk - ku is a martingale.
Now, we can use the optional stopping theorem to prove that E[ST] = uE[T]:
By the optional stopping theorem, we have:
E[ST] = E[(Sk - ku)(T - k) + Sku]
= E[(Sk - ku)(T - k)] + E[Sku]
= E[E[(Sk - ku)(T - k) | E0,...,Ek]] + E[Sku] (using law of total expectation)
= E[(Sk - ku)E[T - k | E0,...,Ek]] + E[Sku] (using linearity of expectation)
= E[(Sk - ku)(E[T | E0,...,Ek] - k)] + E[Sku] (using law of total expectation)
= E[(Sk - ku)(T - k)] + E[Sku] (since T is a bounded stopping time)
= E[SkT - kuT - kS + ku] + E[Sku]
= E[SkT] - uE[KT] - kE[S] + ku + E[Sku] (using linearity of expectation)
= uE[KT] - uE[KT] - kE[S] + ku + E[Sku] (using the optional stopping theorem)
= ku + E[S(T-k)]

Two containers designed to hold water are side by side, both in the shape of a cylinder. Container A has a diameter of 32 feet and a height of 16 feet. Container B has a diameter of 30 feet and a height of 18 feet. Container A is full of water and the water is pumped into Container B until Container B is completely full. After the pumping is complete, what is the volume of water remaining in Container A, to the nearest tenth of a cubic foot?
The volume of a cylinder can be found using the formula V = πr^2h, where V is the volume, r is the radius, and h is the height.
For Container A, the radius is half the diameter, or 16 feet. So the volume of Container A is:
V_A = π(16 ft)^2(16 ft) = 8,192π cubic feet
For Container B, the radius is half the diameter, or 15 feet. So the volume of Container B is:
V_B = π(15 ft)^2(18 ft) = 12,735π cubic feet
To find the volume of water that was transferred from Container A to Container B, we can subtract the volume of Container A from the volume of both containers combined:
V_water = V_A + V_B - V_A = V_B
V_water = 12,735π cubic feet
To find the volume of water remaining in Container A, we can subtract the volume of water that was transferred from the volume of Container A:
V_remaining = V_A - V_water
V_remaining = 8,192π - 12,735π
V_remaining ≈ -3,543.7 cubic feet
However, a negative volume doesn't make sense in this context, so we know that there must be no water remaining in Container A after the transfer. Therefore, the volume of water remaining in Container A to the nearest tenth of a cubic foot is 0.

SVM & Kernel Methods Problem 1 (10 points) In this problem we would like to compare the solutions of hard and soft SVMs on a linearly seperable dataset. Let n > 1 be a fixed number. Is it true that there exists C > 0 such that for every sample S of n training examples with binary label, which are linearly separable, the hard-SVM and the soft-SVM (with parameter C) solutions will return exactly the same weight vector. Justify your answer. (Hint: consider n = 2, d = 1 and S = {(x1, yı), (x2, y2)}. Let a > 0 and consider x1 = a, yı = 1, X2 = –a, y2 = -1. Derive the optimal solution for hard and soft SVM and compare the results.)
It is not true that there exists a C > 0 such that for every sample S of n training examples with binary label, which are linearly separable, the hard-SVM and the soft-SVM (with parameter C) solutions will return exactly the same weight vector.
This can be shown by considering the case where n = 2, d = 1 and S = {(x1, yı), (x2, y2)}. Let a > 0 and consider x1 = a, yı = 1, X2 = –a, y2 = -1.
For the hard-SVM, the optimal solution is to find the weight vector w that maximizes the margin between the two classes while ensuring that all training examples are classified correctly. In this case, the margin is 2a and the weight vector is w = (0, 1) or w = (0, -1), depending on the choice of the positive and negative class labels.
For the soft-SVM with parameter C, the optimal solution is to find the weight vector w and the slack variables ξi that minimize the objective function:
min ||w||^2 + CΣξi
s.t. yi(wT xi) ≥ 1 - ξi, ξi ≥ 0
In this case, since the data is linearly separable, the slack variables will be zero for all training examples and the optimal solution will be the same as for the hard-SVM. However, if C is chosen to be a large value, the soft-SVM may allow some misclassifications by penalizing them with the slack variables. In this case, the optimal solution will be different from the hard-SVM.
Therefore, it is not always true that the hard-SVM and soft-SVM solutions will return exactly the same weight vector for linearly separable data, but they may be the same if the parameter C is chosen appropriately.

Z =(128.5-127.6) / 3.91305 = 0.22
P(127.5 < X < 128.5) = P(-0.02 < Z < 0.22)
P(127.5 < X < 128.5) = P(Z < 0.22) - P(Z < -0.02)
P(127.5 < X < 128.5) =0.58706 - 0.49202
P(127.5 < X < 128.5) =0.0950
(b) at least 128 flights are on time.
P(X > 128) = P(X > 127.5) (by using continues correction)
P(X > 127.5) = P(Z > (127.5-127.6)/3.91305)
P(X > 127.5) = P( Z > -0.02)
P(X > 127.5) = 1- P( Z< -0.02)
P(X > 127.5) = 1- 0.49202
P(X > 127.5) = 0.5079
(c) fewer than 124 flights are on time.
P(X < 124 ) =P(X<124.5) (by using continouse correction)
P(X<124.5) = P(Z < (124.5-127.6)/3.91305)
P(X<124.5) = P(Z < -0.79)
P(X<124.5) = 0.2147

Triangle A’B’C’ is a dilation of triangle ABC with a center of dilation at point D. What is the scale factor of this dilation?
Work Shown:
(A'C')/(AC) = 12/5 = 2.4
or you could say
(B'C')/(BC) = 16.8/7 = 2.4
or
(A'B')/(AB) = 9.6/4 = 2.4
The sides of triangle A'B'C' are 2.4 times longer compared to the corresponding sides of triangle ABC.
