The equation of the parabola that has its focus 13 at (-51,-1) -1) and has directrix. = 4 is (x + 51)² = -11(y – 3/2). Answer is therefore (x + 51)² = -11(y – 3/2).

The given focus of the parabola is (−51, −1) and the given directrix of the parabola is y = 4. We know that for a parabola, the distance between the point and the directrix is equal to the distance between the point and the focus. Therefore, using the formula, we can find the equation of the parabola whose focus and directrix are given.

Let P(x, y) be any point on the parabola. Let F be the focus and l be the directrix. Draw a perpendicular line from point P to the directrix l. Let this line intersect l at a point Q. The distance between point P and the directrix is PQ, and the distance between point P and the focus is PF. Using the distance formula, we can write:

PF = √[(x − x₁)² + (y − y₁)²]PQ = |y − k|

where (x₁, y₁) is the coordinates of the focus, k is the distance between the vertex and the directrix, and the absolute value is taken to ensure that PQ is positive. Since the parabola is equidistant from the focus and directrix, we have:

PF = PQ √[(x − x₁)² + (y − y₁)²] = |y − k|

The equation of the parabola is of the form (x – h)^2 = 4p(y – k).We can write the above equation in terms of the distance between the vertex and the directrix, which is given by k = 4p/(1).Thus, the equation of the parabola is             (x – h)² = 4p(y – k) = 4p(y – 4p) = 16p(y – 4).

The vertex of the parabola is equidistant from the focus and directrix, so the vertex is halfway between the focus and directrix. Therefore, the vertex has coordinates (−51, 3/2).The distance between the vertex and the focus is p, so we have: p = (distance between vertex and focus)/4 = (-2.5 - 3/2)/4 = -11/16.

Substituting this value of p and the coordinates of the vertex into the equation of the parabola, we get:(x + 51)² = -44/16(y – 3/2) ⇒ (x + 51)² = -11(y – 3/2).

The probability that the sum of three dice is greater than 15 more than 20 times when tossed 432 times can be approximated using the Normal distribution.

To solve this problem, we can approximate the distribution of the sum of three dice with a Normal distribution using the Central Limit Theorem. Each die has a uniform distribution with possible outcomes from 1 to 6. The sum of three dice can range from 3 to 18.

The mean of the sum of three dice is given by E(X) = [tex]\frac{(1+2+3+4+5+6)}{6}[/tex] × 3 = 10.5, and the variance is Var(X) =[tex]\frac{1^{2} +2^{2}+3^{2} + 4^{2} + 5^{2} +6^{2} }{6}[/tex] × 3 - [tex]10.5^{2}[/tex] = 8.75.

Next, we need to calculate the probability that the sum is greater than 15. P(X > 15) = 1 - P(X ≤ 15) = 1 - [tex]\frac{P(X-10.5)}{\sqrt{8.75} }[/tex] ≤ [tex]\frac{15-10.5}{\sqrt{8.75} }[/tex]. Using the Normal distribution table or a calculator, we can find the probability associated with the Z-score [tex]\frac{15-10.5}{\sqrt{8.75} }[/tex].

To find the probability of getting a sum greater than 15 more than 20 times when tossing the dice 432 times, we need to use the Normal approximation to calculate the probability of getting a sum greater than 15 in a single toss and then use the binomial distribution to calculate the probability of getting more than 20 successes in 432 trials.

For the second problem, to find the probability that the sum of three dice is greater than 17 four times or more when tossed 648 times, we can use the Poisson approximation. This is because the number of occurrences of a rare event (getting a sum greater than 17) in a fixed interval (648 trials) can be approximated by a Poisson distribution.

The mean of the Poisson distribution can be calculated by multiplying the probability of getting a sum greater than 17 in a single toss by the number of trials. Then, we can use the Poisson distribution formula to calculate the probability of getting four or more occurrences using the mean.

The choice between the Normal and Poisson approximations depends on the conditions of the problem. The Normal approximation is suitable when the number of trials is large, and the probability of success is not too close to 0 or 1. The Poisson approximation is appropriate when the number of trials is large, and the probability of success is small.

In this case, since we are tossing the dice 648 times and looking for the probability of a rare event, the Poisson approximation would be more appropriate.

Given that the infinite geometric sequence is a = {6,54, 486, 4374, 39366,...}

We can see that 2nd term = 6 × 9 and 3rd term = 6 × 9 × 9

So, the infinite geometric sequence is a = {6, 54, 486, ...}

And the common ratio r = 54/6 = 9

Let the sum be S. Then we have,S = a + ar + ar² + ar³ + ... (infinitely many terms)... (1)

Multiplying both sides of (1) by r, we get,Sr = ar + ar² + ar³ + ar⁴ + ... (infinitely many terms)... (2)

Subtracting (2) from (1), we get,S - Sr = a, or S(1 - r) = aS(1 - 9) = 6

Therefore, the sum of the sequence is S = 6/ (1 - 9) = -3/4

Therefore, the sum of all terms in the sequence a = {6,54, 486, 4374, 39366,...} is -3/4.2.

So, the infinite geometric sequence is b = {5, - 5121098/5, (5121098/5)², ...}

And the common ratio r = (-5121098/5)/5 = -10242196/25Let the sum be S.

Subtracting (2) from (1), we get,S - Sr = a, or S(1 - r) = aS(1 - ( -10242196/25)) = 5

Therefore, the sum of the sequence is S = 5/ (1 - ( -10242196/25)) = - (125/2048399)

Therefore, the sum of all terms in the sequence b = {5, *. 5121098 35 245...} is -(125/2048399).

If we slice the solid S perpendicular to the X-axis, the volume of the solid is equal to the integral ∫ab A(x) dx, where A(x) is the area of the cross-section.

When we slice the solid perpendicular to the X-axis, each slice will have a cross-section that is parallel to the Y-axis. The area of this cross-section can be denoted as A(x), where x represents the position along the X-axis. The integral ∫ab A(x) dx represents the sum of the infinitesimal volumes of each cross-section as we move from the lower limit a to the upper limit b along the X-axis.

Integrating A(x) with respect to x allows us to sum up the areas of the cross-sections over the interval [a, b], resulting in the total volume of the solid S. Hence, the volume of the solid S, when sliced perpendicular to the X-axis, is given by the integral ∫ab A(x) dx.

The other options listed (∫ab A(y)dy, ∫ab f(x)dx, ∫ab f(y)dy) do not correctly represent the volume of the solid when sliced perpendicular to the X-axis.

The volume generated by revolving the given area about the x-axis is (π^2 - 8π)/4 units^3. None of the provided answer options match this result.

To find the volume generated by revolving the given area about the x-axis, we can use the method of cylindrical shells.

The formula for the volume of a solid generated by revolving a curve y = f(x) about the x-axis from x = a to x = b is given by:

V = ∫[a,b] 2πx * f(x) * dx

In this case, the curve is defined by y = sin(x), and we are rotating the area between the y-axis, the line y = 1, and the arc of y = sin(x) from x = 0 to x = π/2.

The limits of integration will be from x = 0 to x = π/2.

The height of each cylindrical shell will be the difference between the upper and lower curves: 1 - sin(x).

The radius of each cylindrical shell will be x, as the shells are formed by revolving about the x-axis.

Therefore, the volume generated is:

V = ∫[0,π/2] 2πx * (1 - sin(x)) * dx

Evaluating this integral will give us the volume:

V = 2π ∫[0,π/2] x - x*sin(x) * dx

To calculate this integral, we can use integration techniques such as integration by parts or a computer algebra system.

Evaluating the integral, we find:

V = 2π [ (x^2/2) + cos(x) ] evaluated from x = 0 to x = π/2

V = 2π [ ((π/2)^2/2) + cos(π/2) ] - 2π [ (0^2/2) + cos(0) ]

V = 2π [ (π^2/8) + 0 ] - 2π [ 0 + 1 ]

V = (π^2)/4 - 2π

Simplifying further, we have:

V = (π^2 - 8π)/4

Therefore, the volume generated by revolving the given area about the x-axis is (π^2 - 8π)/4 units^3.

To show that any finite subgroup of a multiplicative group of a field is cyclic, we can use the concept of Lagrange's theorem, which states that the order of a subgroup divides the order of the group.

A cyclic multiplicative group is a group formed by the elements of a field under the operation of multiplication. Specifically, a multiplicative group is a group in which every non-zero element has an inverse with respect to multiplication.

Let G be a finite subgroup of the multiplicative group of a field. By Lagrange's theorem, the order of G must divide the order of the multiplicative group, which is infinite. This implies that the order of G must also be finite. Now, we consider the elements in G and their powers.

Since the order of G is finite, there must exist an element g in G such that the powers of g generate all the elements of G. In other words, G is generated by g, making it a cyclic subgroup. Therefore, any finite subgroup of a multiplicative group of a field is cyclic.

To find the slope of the tangent line to the curve √(2x + 2y) + √(3xy) = 7.9842980738932 at the point (6, 1), calculate the value of dy/dx using a calculator to find the slope of the tangent line at the point (6, 1).

Differentiating the equation implicitly, we obtain: (1/2√(2x + 2y)) * (2 + 2y') + (1/2√(3xy)) * (3y + 3xy') = 0

Simplifying, we have: 1 + y'/(√(2x + 2y)) + (3/2)√(y/x) + (√(3xy))/2 * (1 + y') = 0 Substituting x = 6 and y = 1 into the equation, we get: 1 + y'/(√(12 + 2)) + (3/2)√(1/6) + (√(18))/2 * (1 + y') = 0

Simplifying further, we can solve for y': 1 + y'/(√14) + (3/2)√(1/6) + (√18)/2 + (√18)/2 * y' = 0

Now, solving this equation for y', we find the slope of the tangent line at the point (6, 1).

Now, solve for dy/dx:

18(dy/dx) = (7.9842980738932 - 4√3 - 8)/(√18) - 3

dy/dx = [(7.9842980738932 - 4√3 - 8)/(√18) - 3]/18

The  [tex]$\angle WXY$[/tex] is an acute angle, we know that [tex]$\cos(2\angle WXY)$[/tex] will be positive. The answer is [tex]$WY^2[/tex].

To find the length of yz, we can use the property of tangents to circles.

Let T be the point of tangency between the tangent line at x and the circumcircle of triangle wxy. Since the tangent line at x is parallel to line wz, we have [tex]$\angle XTY=\angle YWZ[/tex].

Inscribed angles that intercept the same arc are equal, so we have [tex]$\angle XTY = \angle WXY$[/tex].

Since [tex]$\angle WXY$[/tex] is an inscribed angle that intercepts arc WY (the same arc as [tex]$\angle XTY$[/tex]), we have [tex]$\angle WXY = \angle XTY$[/tex].

Therefore, we can conclude that [tex]$\angle YWZ = \angle XTY = \angle WXY$[/tex].

In triangle WXY, we have [tex]$\angle WXY + \angle WYX + \angle XYW = 180^\circ$[/tex].

Since [tex]$\angle WXY = \angle XYW$[/tex], we can rewrite the equation as [tex]$\angle XYW + \angle WYX + \angle XYW = 180^\circ$[/tex].

Simplifying, we get [tex]$2\angle XYW + \angle WYX = 180^\circ$[/tex].

Since [tex]$\angle XYW = \angle YWZ$[/tex], we can substitute to get [tex]$2\angle YWZ + \angle WYX = 180^\circ$[/tex].

Since [tex]$\angle YWZ = \angle XTY$[/tex], we can substitute again to get [tex]$2\angle XTY + \angle WYX = 180^\circ$[/tex].

But [tex]$\angle XTY$[/tex] is an exterior angle of triangle [tex]$WXYZ$[/tex], so it is equal to the sum of the other two interior angles, which are [tex]$\angle WXY$[/tex] and [tex]$\angle WYX$[/tex]. Therefore, we have [tex]$2(\angle WXY + \angle WYX) + \angle WYX = 180^\circ$[/tex]

Simplifying, we get [tex]$3\angle WYX + 2\angle WXY = 180^\circ$[/tex].

We are given that WX = 6 and XY = 14.

Applying the Law of Cosines in triangle WXY, we have:

[tex]$WY^2 = WX^2 + XY^2 - 2(WX)(XY)\cos(\angle WXY)$[/tex]

[tex]$WY^2 = 6^2 + 14^2 - 2(6)(14)\cos(\angle WXY)$[/tex]

[tex]$WY^2 = 36 + 196 - 168\cos(\angle WXY)$[/tex]

[tex]$WY^2 = 232 - 168\cos(\angle WXY)$[/tex]

From the equation we derived earlier, [tex]$3\angle WYX + 2\angle WXY = 180^\circ$[/tex].

Rearranging this equation, we get [tex]$\angle WYX = 180^\circ - 2\angle WXY$[/tex].

Substituting this value into the equation, we have:

[tex]$WY^2 = 232 - 168\cos(180^\circ - 2\angle WXY)$[/tex]

Using the cosine difference identity, [tex]$\cos(180^\circ - \theta) = -\cos(\theta)$[/tex]

we can simplify the equation:

It would take approximately 656.96 years for the generation ship to reach Alpha Centauri at a constant speed of 2000.00 km/s.

Given that the nearest stellar neighbor, Alpha Centauri, is located only 4.4 light-years away. And we need to find out how many years before the generation ship reached Alpha Centauri if we launched a "generation ship" at a constant speed of 2000.00 km/s from Earth with a group of people whose descendants will explore and colonize this planet.

Let t be the time in years it takes for the generation ship to reach Alpha Centauri. We can use the formula below to calculate the time.

t = Distance / SpeedWe need to convert light-years into kilometers.

1 light-year = 9.46 ×1012 km

So, the distance between the Earth and Alpha Centauri in kilometers is,

4.4 light-years = 4.4 × 9.46 ×1012 km = 4.15 × 1013 km

Now, substitute the distance and speed into the formula above and solve for t.t = 4.15 × 1013 km / 2000.00 km/s  = 2.075 × 1010 s

We also need to convert seconds to years.

1 year = 31.6 million seconds

Therefore,2.075 × 1010 s / 31.6 million seconds/year= 656.96 years (approx)

Therefore, it will take approximately 656.96 years before the generation ship reached Alpha Centauri. Hence, the required answer is 656.96.

The work done is the line integral of the dot product of the force field and the differential displacement along the path. It represents the energy transferred or expended by a force while moving an object.

To find a nonzero function h(x) such that h(x)F(x, y) is a conservative vector field, we need to determine h(x) such that the vector field

h(x)F(x, y) satisfies the condition of being conservative.

Given the vector field F(x, y) = yi - 2xj, we can write h(x)F(x, y) as

h(x)(yi - 2xj).

For a vector field to be conservative, it must satisfy the condition that the curl of the vector field is zero.

Taking the curl of h(x)F(x, y), we have:

[tex]curl(h(x)F(x, y)) = curl(h(x)(yi - 2xj))[/tex]

Since the curl of a scalar multiple of a vector is the same as the scalar multiple of the curl of the vector, we can write:

[tex]curl(h(x)(yi - 2xj)) = h(x)curl(yi - 2xj)[/tex]

Now, let's calculate the curl of yi - 2xj:

[tex]curl(h(x)(yi - 2xj)) = h(x)curl(yi - 2xj)[/tex]

             = -2 + 0

             = -2

Therefore, for the curl to be zero, we must have:

h(x)(-2) = 0

Since h(x) is nonzero, we can conclude that -2 must be equal to zero, which is not possible. Therefore, there is no nonzero function h(x) that can make h(x)F(x, y) a conservative vector field.

Similarly, to find a nonzero function g(y) such that g(y)F(x, y) is a conservative vector field, we need to determine g(y) such that the vector field g(y)F(x, y) satisfies the condition of being conservative.

Given the vector field F(x, y) = yi - 2xj, we can write g(y)F(x, y) as

g(y)(yi - 2xj).

Taking the curl of g(y)F(x, y), we have:

[tex]curl(g(y)F(x, y)) = curl(g(y)(yi - 2xj))[/tex]

Using the same logic as before, we can write:

[tex]curl(g(y)(yi - 2xj)) = g(y)curl(yi - 2xj)[/tex]

Calculating the curl of yi - 2xj:

[tex]curl(yi - 2xj) = (∂/∂x)(-2x) - (∂/∂y)(1)[/tex]

             = -2 + 0

             = -2

For the curl to be zero, we must have:

g(y)(-2) = 0

Again, since g(y) is nonzero, -2 must be equal to zero, which is not possible. Hence, there is no nonzero function g(y) that can make g(y)F(x, y) a conservative vector field.

To determine the basis for the kernel and image of the linear transformation T, we need to perform the matrix multiplication and analyze the resulting vectors.

Let's start with the given linear transformation:

T(1, 1, 1) = (-2 - 2 - 2 - 23 + 2, 2 - 2 + 2 - 22 - 23, 8 - 21 + 8 - 21 - 4 - 2)

Simplifying the right side, we get:

T(1, 1, 1) = (-25, -46, -34)

(A) Basis for the Kernel of T:

The kernel of T consists of all vectors in the domain (R¹ in this case) that map to the zero vector in the codomain (R³ in this case).

We need to find a basis for the solutions to the equation T(x, y, z) = (0, 0, 0).

Setting up the equation:

(-25, -46, -34) = (0, 0, 0)

From this equation, we can see that there are no solutions. The linear transformation T maps all points in R¹ to a specific point in R³, (-25, -46, -34). Therefore, the basis for the kernel of T is the empty set, denoted as {}.

(B) Basis for the Image of T:

The image of T consists of all vectors in the codomain (R³) that are mapped from vectors in the domain (R¹).

To determine the basis for the image, we need to analyze the resulting vectors from applying T to each of the given vectors:

T(1, 0, 0) = ?

T(0, 1, 0) = ?

T(0, 0, 1) = ?

Let's compute each of these transformations:

T(1, 0, 0) = (-2 - 2 - 2 - 23 + 2, 2 - 2 + 2 - 22 - 23, 8 - 21 + 8 - 21 - 4 - 2) = (-23, -45, -34)

T(0, 1, 0) = (-2 - 2 - 2 - 23 + 2, 2 - 2 + 2 - 22 - 23, 8 - 21 + 8 - 21 - 4 - 2) = (-23, -45, -34)

T(0, 0, 1) = (-2 - 2 - 2 - 23 + 2, 2 - 2 + 2 - 22 - 23, 8 - 21 + 8 - 21 - 4 - 2) = (-23, -45, -34)

From the computations, we can see that all three resulting vectors are the same: (-23, -45, -34).

Therefore, the basis for the image of T is {(−23, −45, −34)}.

Note: In this case, since all vectors in the domain map to the same vector in the codomain, the image of T is a one-dimensional subspace. Thus, any non-zero vector in the image can be considered as a basis for the image of T.

The value of A² is the matrix [187/43 51/43; -158/43 -74/43].

The given 2x2 matrix A has eigenvalues λ = 2 and -1, with corresponding eigenvectors [5 2] and [9 -1] respectively. We are required to find A².

1:We know that if λ is an eigenvalue of a matrix A with an eigenvector x, then λ² is an eigenvalue of A² with an eigenvector x.

Therefore, we can square the eigenvalues and keep the same eigenvectors to find the eigenvalues of A².λ₁ = 2² = 4, with eigenvector [5 2]λ₂ = (-1)² = 1, with eigenvector [9 -1]

2:Using the eigenvectors [5 2] and [9 -1] to form a matrix P, we have:P = [5 9; 2 -1]

3:Using the diagonal matrix D with the eigenvalues, we have:D = [4 0; 0 1]

4:Now, we can express A in terms of P and D as follows:A = PDP⁻¹

We can easily find P⁻¹ as:

P⁻¹ = (1/(-1(5)(-1) - (9)(2)))[-1 -9; -2 5] = [1/43][-5 9; 2 -1]

Using this value of P⁻¹ in the above expression, we get:A = [5 9; 2 -1][4 0; 0 1][1/43][-5 9; 2 -1]

Simplifying, we get:

A = [31/43 33/43; -58/43 -32/43]

Therefore, A² is given by:

A² = A.A = [31/43 33/43; -58/43 -32/43][5 9; 2 -1]= [187/43 51/43; -158/43 -74/43]

To find the variable parameters u₁, u₂, and u₃, we substitute Yp = U₁(x)e^(-x) + U₂(x)e^x + U₃(x)e^(2x) into the given differential equation. By equating the coefficients of the exponential terms, we obtain three second-order linear homogeneous differential equations. Solving these equations will yield the values of u₁, u₂, and u₃, which satisfy the original differential equation.

To find the variable parameters u₁, u₂, and u₃ that make Yp = U₁(x)e^(-x) + U₂(x)e^x + U₃(x)e^(2x) a particular solution of the differential equation, we need to substitute Yp into the differential equation and solve for the unknown functions U₁(x), U₂(x), and U₃(x).

Given the differential equation: y" - 2y" - y' + 2y = e^(3x),

We differentiate Yp with respect to x:

Yp' = U₁'(x)e^(-x) + U₂'(x)e^x + U₃'(x)e^(2x)

Yp" = U₁"(x)e^(-x) + U₂"(x)e^x + U₃"(x)e^(2x)

Substituting these derivatives into the differential equation:

[U₁"(x)e^(-x) + U₂"(x)e^x + U₃"(x)e^(2x)] - 2[U₁'(x)e^(-x) + U₂'(x)e^x + U₃'(x)e^(2x)] - [U₁'(x)e^(-x) + U₂'(x)e^x + U₃'(x)e^(2x)] + 2[U₁(x)e^(-x) + U₂(x)e^x + U₃(x)e^(2x)] = e^(3x)

Next, we group the terms with the same exponential factors:

[e^(-x)(U₁"(x) - 2U₁'(x) - U₁'(x) + 2U₁(x))] + [e^x(U₂"(x) - 2U₂'(x) - U₂'(x) + 2U₂(x))] + [e^(2x)(U₃"(x) - 2U₃'(x) - U₃'(x) + 2U₃(x))] = e^(3x)

Now, equating the corresponding coefficients of the exponential terms on both sides of the equation, we get:

U₁"(x) - 4U₁'(x) + 2U₁(x) = 0 (for e^(-x) term)

U₂"(x) - 4U₂'(x) + 2U₂(x) = 0 (for e^x term)

U₃"(x) - 4U₃'(x) + 2U₃(x) = e^(3x) (for e^(2x) term)

These are second-order linear homogeneous differential equations for U₁(x), U₂(x), and U₃(x) respectively. Solving these equations will give us the variable parameters u₁, u₂, and u₃ that satisfy the original differential equation.

The probability that more than three students will withdraw from the course is approximately 0.033 or 3.3%.

The expected number of withdrawals from this course is 2.5.

To find the probability that more than three students will withdraw, we need to calculate the probability of three or fewer students withdrawing and then subtract that value from 1.

Let's use the binomial distribution to solve this problem. In this case, the probability of a student withdrawing is given as 2.5%, which can be written as 0.025.

The total number of students registered for the course is 100.

To calculate the probability of three or fewer students withdrawing, we need to sum up the probabilities of 0, 1, 2, and 3 students withdrawing. The formula for the binomial distribution is:

[tex]P(X = k) = (nchoose k) \times p^k \times (1 - p)^{(n - k)[/tex]

Where:

n is the number of trials (total number of students, which is 100 in this case)

k is the number of successful trials (number of students withdrawing)

p is the probability of success (probability of a student withdrawing, which is 0.025)

Using this formula, we can calculate the probabilities for k = 0, 1, 2, and 3:

P(X = 0) = (100 choose 0) * 0.025^0 * (1 - 0.025)^(100 - 0)

P(X = 1) = (100 choose 1) * 0.025^1 * (1 - 0.025)^(100 - 1)

P(X = 2) = (100 choose 2) * 0.025^2 * (1 - 0.025)^(100 - 2)

P(X = 3) = (100 choose 3) * 0.025^3 * (1 - 0.025)^(100 - 3)

Next, we sum up these probabilities:

P(0 or 1 or 2 or 3) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3)

Finally, we subtract this value from 1 to get the probability that more than three students will withdraw:

P(more than three) = 1 - P(0 or 1 or 2 or 3)

Now, let's calculate the probabilities:

P(X = 0) = (100 choose 0) * 0.025^0 * (1 - 0.025)^(100 - 0)

= 1 * 1 * 0.975^100

≈ 0.229

P(X = 1) = (100 choose 1) * 0.025^1 * (1 - 0.025)^(100 - 1)

= 100 * 0.025 * 0.975^99

≈ 0.377

P(X = 2) = (100 choose 2) * 0.025^2 * (1 - 0.025)^(100 - 2)

= 4950 * 0.025^2 * 0.975^98

≈ 0.265

P(X = 3) = (100 choose 3) * 0.025^3 * (1 - 0.025)^(100 - 3)

= 161700 * 0.025^3 * 0.975^97

≈ 0.096

P(0 or 1 or 2 or 3) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3)

≈ 0.229 + 0.377 + 0.265 + 0.096

≈ 0.967

P(more than three) = 1 - P(0 or 1 or 2 or 3)

= 1 - 0.967

≈ 0.033

Therefore, the probability that more than three students will withdraw from the course is approximately 0.033 or 3.3%.

To calculate the expected number of withdrawals from this course, we can use the formula for the expected value of a binomial distribution:

E(X) = np

Where:

E(X) is the expected value (expected number of withdrawals)

n is the number of trials (total number of students, which is 100 in this case)

p is the probability of success (probability of a student withdrawing, which is 0.025)

Using this formula, we can calculate the expected number of withdrawals:

E(X) = 100 × 0.025

= 2.5

Therefore, the expected number of withdrawals from this course is 2.5.

To find dt using the chain rule, we have the following information:

f(x, y) = 2 sin(x) - ln(y)

z = 3e

y = cos(t)

Let's start by differentiating z with respect to t:

dz/dt = d(3e)/dt

= 0 (since e is a constant)

Next, we can find dy/dt using the chain rule:

dy/dt = d(cos(t))/dt

= -sin(t)

Now, we can use the chain rule to find dt:

dz/dt = (dz/dx) * (dx/dt) + (dz/dy) * (dy/dt)

Since dz/dt = 0 and dz/dx = (∂f/∂x), dz/dy = (∂f/∂y), we can rewrite the equation as:

0 = (∂f/∂x) * (dx/dt) + (∂f/∂y) * (dy/dt)

We know that f(x, y) = 2 sin(x) - ln(y), so let's find the partial derivatives:

∂f/∂x = 2 cos(x)

∂f/∂y = 2r - 1/[tex]\sqrt{y}[/tex]

Substituting these values into the equation, we have:

0 = (2 cos(x)) * (dx/dt) + (2r - 1/[tex]\sqrt{y}[/tex]) * (-sin(t))

Simplifying the equation further, we can solve for dt:

0 = -2 cos(x) * (dx/dt) - (2r - 1/[tex]\sqrt{y}[/tex]) * sin(t)

Dividing both sides by -2 cos(x) and multiplying by dt:

dt = [(2r - 1/[tex]\sqrt{y}[/tex]) * sin(t)] / (-2 cos(x))

Therefore, dt is given by:

dt = [-sin(t) * (2r - 1/[tex]\sqrt{y}[/tex])] / [2 cos(x)]

Note: The values of r and y were not given in the problem, so the expression for dt remains in terms of those variables. If the specific values of r and y are known, they can be substituted into the equation to obtain a numerical result.
