17 is -42.

a. The value of the swap to firm XYZ is -$23,225.33.

b. This would help to protect the firm against an increase in interest rates.

a. Calculation of the value of the swap to firm XYZ

The value of the swap to firm XYZ can be calculated using the following formula:

Value of Swap = Value of Fixed Leg - Value of Floating Leg

Where Value of Fixed Leg = VFL = (Coupon Rate * Principal * (1 - (1 + r)-n / r))

Value of Floating Leg = VFL = (Interest Rate * Principal * (1 - (1 + r)-n / r))

Where, Coupon Rate = 4% p.a. Principal = $20 million

Interest Rate = LIBOR + Spread, Spread = 0, therefore,

Interest Rate = 4.5% p.a.

Time to Maturity, n = 15 months

Remaining Time to Next Payment = 6 - 2 = 4 months

Therefore, the current six-month LIBOR rate is required to calculate the value of the swap as follows:

Current six-month LIBOR rate = 4.5% * (4/6) + x% * (2/6)x = ((Value of Swap/Principal + (1 - (1 + r)-n / r)) * r) / (1 - (1 + r)-n / r) = 0.0251%

Value of Fixed Leg = VFL = (0.04 * 20,000,000 * (1 - (1 + 0.05/2)-30 / (0.05/2))) = $1,328,816.76

Value of Floating Leg = VFL = (0.0451 * 20,000,000 * (1 - (1 + 0.05/2)-10 / (0.05/2))) = $1,352,042.09

Value of Swap = $1,328,816.76 - $1,352,042.09 = -$23,225.33

Therefore, the value of the swap to firm XYZ is -$23,225.33.

b. Suggest a reason why XYZ entered into the swap in the first place

Firm XYZ might have entered into the swap in the first place to mitigate the risk of a rise in interest rates in the future. By entering into a fixed-for-floating interest rate swap, the firm has fixed its borrowing cost for the duration of the swap at 4%, regardless of the future interest rate changes.

Therefore, this would help to protect the firm against an increase in interest rates.

Answer:

68%

Step-by-step explanation:

The percentage of males in the town who have systolic blood pressure between 98 and 112 is 68%.

It is also called the Gaussian Distribution. It is the most important continuous probability distribution. The curve looks like a bell, so it is also called a bell curve.

For males in a certain town, the systolic blood pressure is normally distributed with a mean of 105 and a standard deviation of 7.

68 percent of the data is within one standard deviation of the mean, i.e. between μ - σ and μ + σ.

μ - σ = 105 - 7 = 98

μ + σ = 105 + 7 = 112

The value for partners savings bank at the end of 1 year is $12,362.70. The value for Selwyn's at the end of 1 year is $12,334.58. The future value obtained by investing in Partners Saving Bank is more as compared to Selwyn’s Saving Bank. Hence Joseph is recommended to choose Partners Saving Bank.

Step-by-step explanation:

The value of the interest rate and the compounding applied, gives the

value in the account after one year.

Reasons:

The amount Joseph receives as gift, A₀ = $12,000

Amount interest from Partner's Savings Bank, r = 3% compounded semiannually

Interest rate offered by Selwyn's, r = 2.75% compounded continuously

Required:

The value of the two account at the end of one year.

Solution:

[tex]A_t = A_0 \cdot \left(1 + \dfrac{r}{2} \right)^{2 \times t}[/tex]

The amount at the end of one year (t = 1) in Partner's Savings Bank is therefore;

[tex]A_t = 12,000 \times \left(1 + \dfrac{0.03}{2} \right)^{2 \times 1} = 12,362.7[/tex]

The value of an account at Selwyn's is therefore;

The interest rate compounded continuously is presented as follows;

[tex]A(t) = \mathbf{A_0 \cdot e^{r \cdot t}}[/tex]

A₀ = The original amount invested = $12,000

Step-by-step explanation:

Answer:

3 + (p • 6)

Step-by-step explanation:

One possible values of the integers is: a = 8020k, b = -10025k, and c = 401k where k is an arbitrary integer.

To find integers s, t, u, v such that 1485s + 952t = 690u + 539v, we can use the Extended Euclidean Algorithm. First, we compute the greatest common divisor of 1485 and 952:

gcd(1485, 952) = gcd(952, 533) = gcd(533, 419) = gcd(419, 114) = gcd(114, 91) = gcd(91, 23) = 23

Using the algorithm, we can write 23 as a linear combination of 1485 and 952:

23 = (-17) * 1485 + (27) * 952

Multiplying both sides by (30), we get:

690 = (-510) * 1485 + (810) * 952

and

539 = (357) * 1485 + (-567) * 952

Therefore,

s = -510u + 357v

t = 810u -567v

where u and v are arbitrary integers.

For the second part of the question, we need to find integers a, b, c, d such that:

211a + 307b +401c +503d =0

One possible way is:

a = -262

b = -169

c = 122

d = 97

To check that this, we substitute these values into the equation:

211(-262) +307(-169) +401(122) +503(97) = -55682 -52083 +51122 +50691 =0

Therefore, this is a valid solution.

Finally, for the third part of the question, we need to find integers a, b, c such that:

690a +539b=401c

Using the Extended Euclidean Algorithm, we can write:

gcd(690, 539) = gcd(539, 151) = gcd(151, 86) = gcd(86, 65) = gcd(65, 21) = gcd(21, 2) = 1

and

1 = (20) * 690 + (-25) * 539

Multiplying both sides by 401, we get:

401 = (8020) * 690 + (-10025) * 539

(a) The improper integral ∫[0,∞] [tex](xe^(-2x)dx)[/tex] converges.

(b) To evaluate the integral ∫[0,1] [tex](4\sqrt{1-x^2}dx)[/tex], we can use the trigonometric substitution x = sin(θ).

(c) The general solution to the given differential equation is y = ln|x + 2| - ln|x - 1| + C.

(a) To determine if the improper integral ∫[0,∞] [tex](xe^{-2x}dx)[/tex] converges or diverges, we can use the limit comparison test.

Let's consider the function f(x) = x and the function g(x) = [tex]e^{-2x}[/tex].

Since both f(x) and g(x) are positive and continuous on the interval [0,∞], we can compare the integrals of f(x) and g(x) to determine the convergence or divergence of the given integral.

We have ∫[0,∞] (x dx) and ∫[0,∞] [tex](e^(-2x) dx)[/tex].

The integral of f(x) is ∫[0,∞] (x dx) = [[tex]x^2/2[/tex]] evaluated from 0 to ∞, which gives us [∞[tex]^2/2[/tex]] - [[tex]0^2/2[/tex]] = ∞.

The integral of g(x) is ∫[0,∞] [tex](e^{-2x} dx)[/tex] = [tex][-e^{-2x}/2][/tex] evaluated from 0 to ∞, which gives us [[tex]-e^{-2\infty}/2[/tex]] - [[tex]-e^0/2[/tex]] = [0/2] - [-1/2] = 1/2.

Since the integral of g(x) is finite and positive, while the integral of f(x) is infinite, we can conclude that the given integral ∫[0,∞] ([tex]xe^{-2x}dx[/tex]) converges.

(b) To evaluate the integral ∫[0,1] (4√([tex]1-x^2[/tex])dx), we can make the trigonometric substitution x = sin(θ).

When x = 0, we have sin(θ) = 0, so θ = 0.

When x = 1, we have sin(θ) = 1, so θ = π/2.

Differentiating x = sin(θ) with respect to θ, we get dx = cos(θ) dθ.

Now, substituting x = sin(θ) and dx = cos(θ) dθ in the integral, we have:

∫[0,1] (4√([tex]1-x^2[/tex])dx) = ∫[0,π/2] (4√(1-[tex]sin^2[/tex](θ)))cos(θ) dθ.

Simplifying the integrand, we have √(1-[tex]sin^2[/tex](θ)) = cos(θ).

Therefore, the integral becomes:

∫[0,π/2] (4[tex]cos^2[/tex](θ)cos(θ)) dθ = ∫[0,π/2] (4[tex]cos^3[/tex](θ)) dθ.

Now, we can integrate the function 4[tex]cos^3[/tex](θ) using standard integration techniques:

∫[0,π/2] (4[tex]cos^3[/tex](θ)) dθ = [sin(θ) + (3/4)sin(3θ)] evaluated from 0 to π/2.

Plugging in the values, we get:

[sin(π/2) + (3/4)sin(3(π/2))] - [sin(0) + (3/4)sin(3(0))] = [1 + (3/4)(-1)] - [0 + 0] = 1 - 3/4 = 1/4.

Therefore, the value of the integral ∫[0,1] (4√([tex]1-x^2[/tex])dx) is 1/4.

(c) To find the general solution to the differential equation ([tex]x^2 + x - 2[/tex])(dy/dx) = 3, for x ≠ -2, 1, we need to separate the variables and integrate both sides.

(dy/dx) = 3 / ([tex]x^2 + x - 2[/tex]).

∫(dy/dx) dx = ∫(3 / ([tex]x^2 + x - 2[/tex])) dx.

Integrating the left side gives us [tex]y + C_1[/tex], where [tex]C_1[/tex] is the constant of integration.

To evaluate the integral on the right side, we can factor the denominator:

∫(3 / ([tex]x^2 + x - 2[/tex])) dx = ∫(3 / ((x + 2)(x - 1))) dx.

Using partial fractions, we can express the integrand as:

3 / ((x + 2)(x - 1)) = A / (x + 2) + B / (x - 1).

Multiplying both sides by (x + 2)(x - 1), we have:

3 = A(x - 1) + B(x + 2).

Expanding and equating coefficients, we get:

0x + 3 = (A + B)x + (-A + 2B).

Equating the coefficients of like terms, we have:

A + B = 0,

- A + 2B = 3.

Solving this system of equations, we find A = -3 and B = 3.

3 / ((x + 2)(x - 1)) = (-3 / (x + 2)) + (3 / (x - 1)).

∫(3 / ([tex]x^2 + x - 2[/tex])) dx = -3∫(1 / (x + 2)) dx + 3∫(1 / (x - 1)) dx.

-3ln|x + 2| + 3ln|x - 1| + C2,

where C2 is another constant of integration.

Therefore, the general solution to the differential equation is:

y = -3ln|x + 2| + 3ln|x - 1| + C,

where C = C1 + C2 is the combined constant of integration.

Answer:

(√3·x - 1)(√3·x + 1)(4x - 3)

Step-by-step explanation:

Note that the last two coefficients are -4 and +3, and the associated factor is (4x - 3).

The first two terms are

12x^3 - 9x^2, which become 3x(4x^2 - 3x) through factoring and then 3x^2(4x - 3).  

Therefore, 12x3 – 9x2 – 4x + 3 can be rewritten as:

                   (4x - 3)(3x^2 - 1).  

It's possible to factor 3x^2 - 1, even though 3 is not a perfect square.  Write 3x^2 - 1 as (√3·x - 1)(√3·x + 1)

The image of the given arbitrary quadratic polynomial is T([tex]ax^2 + bx + c[/tex]) = [tex](-2a + 2c)x^2 + (-2b + a)x + (-2a + b + 7c)[/tex].

To find the image of the arbitrary quadratic polynomial [tex]ax^2 + bx + c[/tex] under the linear transformation T, we can express the polynomial in terms of the standard basis of P3, which is {[tex]1, x, x^2[/tex]}.

The polynomial [tex]ax^2 + bx + c[/tex] can be written as a linear combination of the basis vectors:

[tex]ax^2 + bx + c = a(x^2) + b(x) + c(1)[/tex]

Since we know the values of T(1), T(x), and T([tex]x^2[/tex]), we can substitute them into the expression:

[tex]T(ax^2 + bx + c) = aT(x^2) + bT(x) + cT(1)[/tex]

Substituting the given values:

[tex]T(ax^2 + bx + c) = a(-2x^2 + x - 2) + b(-2x + 1) + c(2x^2 + 7)[/tex]

Simplifying the expression:[tex]T(ax^2 + bx + c) = (-2ax^2 + ax - 2a) + (-2bx + b) + (2cx^2 + 7c)[/tex]

Combining like terms:

[tex]T(ax^2 + bx + c) = (-2a + 2c)x^2 + (-2b + a)x + (-2a + b + 7c)[/tex]

Therefore, the image of the arbitrary quadratic polynomial [tex]ax^2 + bx + c[/tex] under the linear transformation T is [tex](-2a + 2c)x^2 + (-2b + a)x + (-2a + b + 7c)[/tex].

The value of the chi-square statistic for this independence test is approximately 82.23.

To calculate the expected values for the independence test, we need to determine the expected number of individuals in each category if age and voting behavior were independent. We can calculate the expected values using the formula:

Expected value = (Row total * Column total) / Total number of observations

Let's calculate the expected values for each category:

Age Voted?         Under 30    30 - 50    Over 50    Total

Yes                       35                  64               25               124

No                        56                  19                 1                 76

Total                     91                  83               26               200

Expected value for "Yes" under "Under 30" category:

Expected value = (91 * 124) / 200 = 56.57 (approximately 57)

Expected value for "No" under "Under 30" category:

Expected value = (91 * 76) / 200 = 34.82 (approximately 35)

Similarly, calculate the expected values for the other categories:

Expected values for "Yes" in the "30 - 50" and "Over 50" categories:

30 - 50: 83 * 124 / 200 ≈ 51.77 (approximately 52)

Over 50: 26 * 124 / 200 ≈ 16.12 (approximately 16)

Expected values for "No" in the "30 - 50" and "Over 50" categories:

30 - 50: 83 * 76 / 200 ≈ 31.63 (approximately 32)

Over 50: 26 * 76 / 200 ≈ 9.88 (approximately 10)

The expected table for the independence test is as follows:

Age Voted?         Under 30    30 - 50    Over 50      Total

Yes                       57                  52               16               124

No                        35                  32               10                76

Total                     91                  83               26               200

To find the chi-square statistic for this independence test, we use the formula:

χ² = Σ [(Observed value - Expected value)² / Expected value]

Now, let's calculate the chi-square statistic by summing the values for each category:

χ² = [(35 - 57)² / 57] + [(64 - 52)² / 52] + [(25 - 16)² / 16] + [(56 - 35)² / 35] + [(19 - 32)² / 32] + [(1 - 10)² / 10]

χ² = 23.09 + 2.46 + 5.06 + 40.69 + 4.53 + 6.4

χ² ≈ 82.23

Therefore, the value of the chi-square statistic for this independence test is approximately 82.23.
