The second-year depreciation using MACRS is $96,835.20.  

To calculate the MACRS depreciation, we need to determine the depreciation rate for the asset based on its classification as 5-year property. Here is the breakdown of the MACRS depreciation rates for 5-year property:

Year 1: 20.00%

Year 2: 32.00%

Year 3: 19.20%

Year 4: 11.52%

Year 5: 11.52%

Year 6: 5.76%

Since we want to calculate the depreciation for the second year, we'll use the depreciation rate of 32.00%.

First, we need to calculate the depreciable base, which is the original cost of the asset minus the estimated salvage value:

Depreciable Base = Purchase Cost - Salvage Value

Depreciable Base = $331,265 - $28,505

Depreciable Base = $302,760

Next, we calculate the depreciation for the second year:

Depreciation = Depreciable Base × Depreciation Rate

Depreciation = $302,760 × 32.00%

Depreciation = $96,835.20

Therefore, the second-year depreciation using MACRS is $96,835.20.

The solution to the given linear system of differential equations with initial conditions x(0) = -11 and y(0) = -8 is x(t) = -4e^(2t) - 7e^(-4t) and y(t) = -6e^(2t) + 4e^(-4t).

To find the solution, we can use the method of solving linear systems of differential equations. By taking the derivatives of x and y with respect to t, we have x' = 8x - 6y and y' = 4x - 2y.

We can rewrite the system of equations in matrix form as X' = AX, where X = [x y]^T and A = [[8 -6], [4 -2]]. The general solution of this system can be written as X(t) = Ce^(At), where C is a constant matrix.

By finding the eigenvalues and eigenvectors of matrix A, we can express A in diagonal form as A = PDP^(-1), where D is the diagonal matrix of eigenvalues and P is the matrix of eigenvectors. In this case, the eigenvalues are 2 and -4, and the corresponding eigenvectors are [1 1]^T and [1 -2]^T.

Substituting these values into the formula for X(t), we get X(t) = C₁e^(2t)[1 1]^T + C₂e^(-4t)[1 -2]^T.

Using the initial conditions x(0) = -11 and y(0) = -8, we can solve for the constants C₁ and C₂. After solving the system of equations, we find C₁ = -3 and C₂ = -1.

Therefore, the final solution to the system of differential equations is x(t) = -4e^(2t) - 7e^(-4t) and y(t) = -6e^(2t) + 4e^(-4t).

Hence, the absolute extrema of the function on the closed interval g(x) = 3x^2x - 2 , [−2, 1] is the absolute maximum of `1` and the absolute minimum of `-29`.

Let's find the absolute extrema of the function on the closed interval. `g(x) = 3x^2x - 2` , [−2, 1]

First, we find critical values of the given function.

Critical values of the function are the values where the function is either not differentiable or the derivative is equal to 0. Let's find the derivative of `g(x)` by using the product rule.`g'(x) = 3x^2 + 6x(x - 2) = 3x^2 + 6x^2 - 12x = 9x^2 - 12x`

To find the critical points, we equate `g'(x)` to 0.  `g'(x) = 0  => 9x^2 - 12x = 0`Factorizing we get, `9x^2 - 12x = 3x(3x - 4) = 0`

Hence `x = 0, 4/3` are the critical points. Now, let's find the value of `g(x)` at the critical points and at the endpoints of the interval `[-2, 1]`

to determine the absolute extrema of the function.The table showing the value of `g(x)` at critical points and endpoints of the interval xg(x)-29-17/9(4/3)-20/3(0)-2(1)1

First, evaluate `g(-2), g(0), g(1) and g(4/3)` , and write the results in the above table.`g(-2) = 3(-2)^2(-2) - 2 = -26``g(0) = 3(0)^2(0) - 2 = -2``g(1) = 3(1)^2(1) - 2 = 1``g(4/3) = 3(4/3)^2(4/3) - 2 = 18/3

So, the maximum value of `g(x)` on the interval [−2, 1] is `1`, and the minimum value of `g(x)` on the interval [−2, 1] is `-29`.

Therefore, the absolute maximum of `g(x)` on the interval [−2, 1] is `1`, and the absolute minimum of `g(x)` on the interval [−2, 1] is `-29`.

a) W(y1, y2) = 2xe^(-4x) b) Yes, {y1, y2} is a fundamental set for the given differential equation.

a) To find the Wronskian of y1 and y2, we need to compute the determinant of the matrix formed by the derivatives of y1 and y2.

Let's start by finding the first derivative of y1 and y2:

y1' = d/dx(e^(-2x)) = -2e^(-2x)

y2' = d/dx(xe^(-2x)) = e^(-2x) - 2xe^(-2x)

Now, let's form the matrix and calculate its determinant:

W(y1, y2) = |y1' y2'|

|-2e^(-2x) e^(-2x) - 2xe^(-2x)|

Expanding the determinant, we have:

W(y1, y2) = (-2e^(-2x))(e^(-2x) - 2xe^(-2x)) - (-2e^(-2x))(e^(-2x) - 2xe^(-2x))

= -2e^(-4x) + 4xe^(-4x) + 2e^(-4x) - 4xe^(-4x)

= 2xe^(-4x)

Therefore, the Wronskian of y1 and y2 on (-∞, ∞) is W(y1, y2) = 2xe^(-4x).

b) To determine if {y1, y2} is a fundamental set for the given differential equation, we need to check if their Wronskian is nonzero for all values of x.

In this case, the differential equationW(y1, y2) = 2xe^(-4x) is not zero for any value of x in the interval (-∞, ∞). Therefore, {y1, y2} is indeed a fundamental set for the given differential equation.

The equation of the tangent line at x = π/2 is y = -πx + π/4

The derivative of y = tan(x) using tan(x) = sin(x)/cos(x) is y' = sec²(x)

From the question, we have the following parameters that can be used in our computation:

f(x) = x²sin(3x)

Calculate the slope of the line by differentiating the function

So, we have

dy/dx = x(2sin(3x) + 3xcos(3x))

The point of contact is given as

x = π/2

So, we have

dy/dx = π/2(2sin(3π/2) + 3π/2 * cos(3π/2))

Evaluate

dy/dx = -π

By defintion, the point of tangency will be the point on the given curve at x = -π

So, we have

y = (π/2)² * sin(3π/2)

y = (π/2)² * -1

y = -(π/2)²

This means that

(x, y) = (π/2, -(π/2)²)

The equation of the tangent line can then be calculated using

y = dy/dx * x + c

So, we have

y = -πx + c

Make c the subject

c = y + πx

Using the points, we have

c = -(π/2)² + π * π/2

Evaluate

c = -π²/4 + π²/2

Evaluate

c = π/4

So, the equation becomes

y = -πx + π/4

Hence, the equation of the tangent line is y = -πx + π/4

Given that

y = tan(x)

By definition

tan(x) = sin(x)/cos(x)

So, we have

y = sin(x)/cos(x)

Next, we differentiate using the quotient rule

So, we have

y' = [cos(x) * cos(x) - sin(x) * -sin(x)]/cos²(x)

Simplify the numerator

y' = [cos²(x) + sin²(x)]/cos²(x)

By definition, cos²(x) + sin²(x) = 1

So, we have

y' = 1/cos²(x)

Simplify

y' = sec²(x)

Hence, the derivative is y' = sec²(x)

To find the area bounded by a curve and determine the volume of the rotating object when the area is rotated about the y-axis, we first sketch the region enclosed by the curve. Then, we calculate the area of the enclosed region using integration. Finally, we use the obtained area to determine the volume of the solid of revolution by integrating the cross-sectional areas perpendicular to the rotation axis.

To sketch the area bounded by the curve, we need the equation of the curve or a description of its shape. Without specific information, it is difficult to provide a detailed sketch.

To determine the area of the enclosed region, we integrate the curve's equation with respect to x or y (depending on how the curve is defined) within the appropriate limits.

Once we have the area, we can calculate the volume of the solid of revolution. Since the region is rotated about the y-axis, each cross-section perpendicular to the axis will be a disk. We can integrate the areas of these disks using cylindrical shells or the disk/washer method to obtain the volume of the solid.

However, without the specific equation or description of the curve, it is not possible to provide a detailed calculation or a more specific explanation.

The two cars are closest to each other after approximately 3.33 hours, and the corresponding closest distance between the two cars is approximately 66.67 km.

Let's consider the motion of car A relative to car B. Car A is moving eastwards at a speed of 60 km/hr, while car B is moving northwards at a speed of 80 km/hr. We can think of car A's motion as the combination of its eastward velocity and car B's northward velocity. The relative velocity of car A with respect to car B is obtained by subtracting the velocities: (60 km/hr) - (80 km/hr) = -20 km/hr.

Now, let's determine the time when car A and car B are closest to each other. Since the relative velocity is negative, it implies that car A is moving towards car B. The closest distance between the two cars will occur when car A intersects the path of car B.

The time it takes for car A to cover the distance of 200 km towards the intersection point O is given by t = 200 km / 60 km/hr = 3.33 hours. During this time, car B will have traveled a distance of (80 km/hr) * (3.33 hr) = 266.67 km towards the intersection point.

At this point, car A is at a distance of 200 - 266.67 = -66.67 km relative to the intersection point. However, we need to consider the magnitudes of distances, so the distance is 66.67 km.

Therefore, the two cars are closest to each other after approximately 3.33 hours, and the corresponding closest distance between the two cars is approximately 66.67 km.

0.2 + 0.1 + 0.3 + 0.3 + P = 1

Solving for P, we get P = 0.1.

(ii) The mean of X is calculated by taking the sum of all the possible values of X, multiplied by their corresponding probabilities. This gives us the equation:

E(X) = 1 * 0.2 + 2 * 0.1 + 3 * 0.3 + 4 * 0.3 + 5 * P

Substituting P = 0.1 into this equation, we get E(X) = 2.5.

(iii) The variance of X is calculated by taking the square of the difference between the mean and each possible value of X, multiplied by their corresponding probabilities. This gives us the equation:

Var(X) = (1 - 2.5)^2 * 0.2 + (2 - 2.5)^2 * 0.1 + (3 - 2.5)^2 * 0.3 + (4 - 2.5)^2 * 0.3 + (5 - 2.5)^2 * 0.1

Average credit hour load = 646 / 40 = 16.15

Therefore, the average credit hour load is 16.15.

2.2 To calculate the median credit hour load, we need to arrange the credit hour values in ascending order:

13 14 14 14 15 15 15 15 16 16

16 17 17 17 18 18 19 20 20

The median is the middle value when the data is arranged in ascending order. Since we have 40 data points, the median will be the average of the 20th and 21st values:

Median = (15 + 15) / 2 = 15

To find the velocity function of the proton, we need to integrate the acceleration function with respect to time. Given that the acceleration function is a(t) = 40/[tex](4t + 1)^2[/tex], we can integrate it to obtain the velocity function.

∫a(t) dt = ∫(40/[tex](4t + 1)^2)[/tex] dt

To integrate this, we can use a substitution. Let u = 4t + 1, then du = 4dt. Rearranging the equation, we have dt = du/4.

Substituting the values, we get:

∫(40/([tex]4t + 1)^2)[/tex] dt = ∫[tex](40/u^2)[/tex] (du/4)

Simplifying the expression, we have:

(1/4) ∫[tex](40/u^2)[/tex]du

Now we can integrate with respect to u:

(1/4) * (-40/u) + C

Simplifying further:

-10/u + C

Substituting back the value of u, we have:

-10/(4t + 1) + C

Since the velocity is given as v = 50 cm/s when t = 0 s, we can use this information to find the constant C.

v(0) = -10/(4(0) + 1) + C

50 = -10/1 + C

We have to find `det(A - λI)`det(A - λI) = (2 - λ) * (-13 - λ) * 7 + 3 * 4 * 0 - 3 * (-13 - λ) * 0 - 0 * 2 * 7 - 4 * 3 * (2 - λ)det(A - λI) = λ^3 - 5λ^2 - 39λdet(A - λI) = λ(λ^2 - 5λ - 39)det(A - λI) = λ(λ - 13)(λ + 3)Eigenvalues = {13, -3, 0}We have three eigenvalues, so we have to find the eigenvectors for each of them. Let's start with 13.

The formula for the eigenvectors is `A * v = λ * v`, where `v` is the eigenvector that we are trying to find. So we have to solve this equation `(A - λI) * v = 0` to find the eigenvectors.For λ = 13,(A - λI) = [[-11, 3], [4, -26], [0, 7]](A - λI) * v = 0⇒ [-11, 3] [x]   [0] = [0]  [y]     [0]   [0]     [z]Solving these equations will give us the eigenvector corresponding to λ = 13x = -3y = 11z = 0So the eigenvector corresponding to λ = 13 is [-3, 11, 0].

Similarly, for λ = -3,(A - λI) = [[5, 3], [4, -10], [0, 7]](A - λI) * v = 0⇒ [5, 3] [x]   [0] = [0]  [y]     [0]   [0]     [z]Solving these equations will give us the eigenvector corresponding to λ = -3x = -1y = 1z = 0So the eigenvector corresponding to λ = -3 is [-1, 1, 0].Finally, for λ = 0,(A - λI) = [[2, 3], [4, -13], [0, 7]](A - λI) * v = 0⇒ [2, 3] [x]   [0] = [0]  [y]     [0]   [0]     [z]

Solving these equations will give us the eigenvector corresponding to λ = 0x = -3y = 2z = 1So the eigenvector corresponding to λ = 0 is [-3, 2, 1].Hence, the eigenvalues of the given matrix are {13, -3, 0} and the eigenvectors are [-3, 11, 0], [-1, 1, 0], and [-3, 2, 1].

When the price is $16 per unit and increasing at a rate of 76 cents per week, the supply is changing by 6 units per week.

To find the rate at which the supply is changing, we need to differentiate the given equation with respect to time. Let's denote the supply as x and time as t.

From the given equation, we have:

x² - 6x√√p - p² = 85

Differentiating both sides with respect to t, we get:

2x(dx/dt) - 6(1/2)(1/√p)(dx/dt)√√p - 0 = 0

Simplifying this equation, we have:

2x(dx/dt) - 3(1/√p)(dx/dt)√√p = 0

Factoring out dx/dt, we get:

(dx/dt)(2x - 3√p) = 0

Since we are interested in the rate of change of supply, dx/dt, we set the expression in parentheses equal to zero and solve for x:

2x - 3√p = 0

2x = 3√p

x = (3√p)/2

Now, let's substitute the given values:

Given degree of confidence = 90% Number of adults selected randomly from one town, n = 92

Number of adults who have health insurance, p = 61

a) To construct a 90% confidence interval for the true proportion of all adults in the town who have health insurance, we use the following formula:

[tex]CI = p ± z (α/2) × (sqrt(p * q/n))[/tex]

Where,CI = Confidence intervalp = Proportion of adults who have health insurance

q = 1 - pp

= 61/92q

If the Laplace transform of f(t) = e cos(et) + t sin(t) is determined then, (F(s) = es/(e²+ s²) + s/(1+s²)²) (option d).

a. It is an odd function which gives a value of a = 0

To determine if the function f(x) = x + sin(x) is odd, we need to check if f(-x) = -f(x) holds for all x.

f(-x) = -x + sin(-x) = -x - sin(x)

Since f(x) = x + sin(x) and f(-x) = -x - sin(x) are not equal, the function f(x) is not odd. Therefore, option a is incorrect.

b. Its Fourier series is classified as a Fourier cosine series where a = 0

To determine the classification of the Fourier series for the function f(x) = x + sin(x), we need to analyze the periodicity and symmetry of the function.

The function f(x) = x + sin(x) is not symmetric about the y-axis, which means it is not an even function. However, it does have a periodicity of 2π since sin(x) has a period of 2π.

For a Fourier series, if a function is not odd or even, it can be expressed as a combination of sine and cosine terms. In this case, the Fourier series of f(x) would be classified as a Fourier series (not specifically cosine or sine series) with both cosine and sine terms present. Therefore, option b is incorrect.

c. It is neither an odd nor even function, thus no classification can be deduced.

Based on the analysis above, since f(x) is neither odd nor even, we cannot classify its Fourier series as either a Fourier cosine series or a Fourier sine series. Thus, option c is correct.

Regarding the Laplace transform of f(t) = e cos(et) + t sin(t):

d. F(s) = es/(e²+ s²) + s/(1+s²)².

The Laplace transform of f(t) = e cos(et) + t sin(t) can be calculated using the properties and theorems of Laplace transforms. Applying the shifting theorem on the terms, we can determine the Laplace transform as follows:

L{e cos(et)} = s / (s - e)

L{t sin(t)} = 2 / (s² + 1)²

Combining these two Laplace transforms, we have:

F(s) = L{e cos(et) + t sin(t)} = s / (s - e) + 2 / (s² + 1)²

    = es / (e² + s²) + 2 / (s² + 1)²

Therefore, option d is correct.

The probability of Type I error, also known as the significance level (α), calculated based on rejection region for a one-tailed test. In this case, with a rejection region of t > 1.895, the probability of Type I error is 0.05.

To calculate the probability of Type I error, we need to determine the significance level (α) associated with the given rejection region.

In this scenario, the rejection region is t > 1.895. Since it is a one-tailed test with the alternative hypothesis HA: μ > 15, we are only interested in the upper tail of the t-distribution.

By referring to the t-distribution table or using statistical software, we can find the critical t-value corresponding to a desired significance level. In this case, the critical t-value is 1.895.

The probability of Type I error is equal to the significance level (α), which is the probability of rejecting the null hypothesis when it is actually true. In this case, with a rejection region of t > 1.895, the significance level is 0.05.

Therefore, the probability of Type I error is 0.05, indicating that there is a 5% chance of erroneously rejecting the null hypothesis when it is true.

a. The relation R is reflexive.

b. The relation R is symmetric.

c. The relation R is not transitive.

d. The relation R is not an equivalence relation.

To draw the undirected graph representing the relation R = {(1, 2), (1, 1), (2, 1), (1, 3), (3, 1), (3, 3)}, we can represent each element as a node and draw edges between the nodes based on the pairs in the relation.

The graph representation of the relation R is as follows:

    1 ---- 2

    | \    |

    |  \   |

    |   \  |

    3 ---- 3

a. Reflexive:

A relation is reflexive if every element is related to itself. In this case, we have (1, 1), (2, 2), and (3, 3) in the relation. Since each element is related to itself, the relation R is reflexive.

b. Symmetric:

A relation is symmetric if for every pair (a, b) in the relation, (b, a) is also in the relation. In this case, we have (1, 2) in the relation, but (2, 1) is also present. Similarly, we have (1, 3) in the relation, but (3, 1) is also present. Therefore, the relation R is symmetric.

c. Transitive:

A relation is transitive if for every pair of elements (a, b) and (b, c) in the relation, (a, c) is also in the relation. In this case, we have (1, 2) and (2, 1) in the relation. However, we don't have (1, 1) in the relation. Therefore, the relation R is not transitive.

d. Equivalence relation:

An equivalence relation is a relation that is reflexive, symmetric, and transitive. Since the relation R is not transitive, it is not an equivalence relation.

In summary:

a. The relation R is reflexive.

b. The relation R is symmetric.

c. The relation R is not transitive.

Answer:

a. The relation is not reflexive because (2,2) is not present.

b. The relation is symmetric because for every (a,b) in R, (b,a) is also present.

c. The relation is not transitive because (2,1) and (1,2) are present, but (2,2) is not present.

d. The relation is not an equivalence relation because it fails to satisfy reflexivity and transitivity.

To represent the relation R = {(1,2), (1, 1), (2,1), (1,3), (3, 1), (3,3)} as an undirected graph:

    1 --- 2

   / \   /

  /   \ /

 3 --- 3

a. Reflexivity: A relation R is reflexive if every element in the set is related to itself. In this case, (1,1) and (3,3) are present in the relation, so it is not reflexive since (2,2) is not present.

b. Symmetry: A relation R is symmetric if whenever (a,b) is in R, then (b,a) is also in R. In this case, (1,2) is present, but (2,1) is also present. Similarly, (1,3) is present, but (3,1) is also present. Therefore, the relation is symmetric.

c. Transitivity: A relation R is transitive if whenever (a,b) and (b,c) are in R, then (a,c) is also in R. In this case, we can see that (1,2) and (2,1) are present, but (1,1) is not present. Therefore, the relation is not transitive.

d. Equivalence relation: An equivalence relation is a relation that is reflexive, symmetric, and transitive. Since the relation in question is not reflexive (as discussed in part a) and not transitive (as discussed in part c), it is not an equivalence relation.

The Sum of Squared Error is a measure of the overall deviation between observed and predicted values in a regression model.

The Sum of Squared Error (SSE) is a fundamental concept in regression analysis. It quantifies the discrepancy between the observed values and the predicted values generated by a regression model. To calculate SSE, we square the differences between each observed data point and its corresponding predicted value, summing up these squared errors for all data points. Rounding the answer to two decimal places, if necessary, ensures a concise representation.

S is not a subspace of R² since S fails to satisfy all three axioms. The subset S is therefore defined by y = 7x + 1 in R² is not a subspace of R².

To prove that S is not a subspace of R², let us recall the three axioms that must be met in order to be a subspace. Let U be a subset of Rⁿ. Then U is a subspace of Rⁿ if and only if all three of the following conditions hold:

1. The zero vector is in U

2. U is closed under vector addition

3. U is closed under scalar multiplication.

Let us evaluate each of these axioms for the subset S defined by y = 7x + 1 in R².

1. The zero vector is in U:If we put x = 0, we can see that the vector <0, 1> is in S. However, <0, 0> is not in S because the y coordinate would be 1 instead of 0. Therefore, S does not contain the zero vector.

2. U is closed under vector addition: Let u =  and v =  be two vectors in S. We need to show that u + v is in S. Adding the two vectors together, we get u + v = . The equation y = 7x + 1 does not hold for this vector since the y-intercept is 2 instead of 1. Therefore, S is not closed under vector addition.

3. U is closed under scalar multiplication: Let c be any scalar and let u =  be a vector in S. We need to show that cu is in S. Multiplying the vector by the scalar, we get cu = . This vector does not satisfy the equation y = 7x + 1, so S is not closed under scalar multiplication.

Since S fails to satisfy all three axioms, we can conclude that S is not a subspace of R². Therefore, the subset S defined by y = 7x + 1 in R² is not a subspace of R².

To determine the volume generated by rotating the area bounded by y = √x and y = -1/2x around y = 3, we can use the method of cylindrical shells.

The volume V is given by the integral:

V = ∫(2πy)(x)dx

To find the limits of integration, we need to determine the x-values where the two curves intersect.

Setting √x = -1/2x, we have:

√x + 1/2x = 0

Multiplying both sides by 2x to eliminate the denominator, we get:

2x√x + 1 = 0

Rearranging the equation, we have:

2x√x = -1

Squaring both sides, we get:

4x²(x) = 1

4x³ = 1

x³ = 1/4

Taking the cube root of both sides, we find:

x = 1/∛4

Therefore, the limits of integration are x = 0 to x = 1/∛4.

Substituting y = √x into the formula for the volume:

V = ∫(2πy)(x)dx

V = ∫(2π√x)(x)dx

Integrating with respect to x:

V = 2π∫x^(3/2)dx

V = 2π(2/5)x^(5/2) + C

Evaluating the integral from x = 0 to x = 1/∛4:

V = 2π[(2/5)(1/∛4)^(5/2) - (2/5)(0)^(5/2)]

V = 2π[(2/5)(1/∛4)^(5/2)]

V = 2π(2/5)(1/√8)

V = 2π(2/5)(1/2√2)

V = 2π(1/5√2)

V = (2π/5√2)

Simplifying further, we have:

V = (2π√2)/10

Therefore, the volume generated is (2π√2)/10, which is approximately equal to 0.89π.

The correct answer is not provided in the options given.

In this problem, we are given a normal distribution of marks on a statistics midterm exam with a mean of 78 and a standard deviation of 6. We are asked to find the probabilities for two scenarios are as follows :

a) To find the probability that a randomly selected student has a midterm mark less than 75, we need to calculate the area under the normal distribution curve to the left of 75.

First, we need to standardize the value of 75 using the z-score formula:

a) To find the probability that a randomly selected student has a midterm mark less than 75:

[tex]z &= \frac{x - \mu}{\sigma} \\\\&= \frac{75 - 78}{6} \\\\\\&= -0.5[/tex]

Using a standard normal distribution table or a calculator, we can find the corresponding probability. In this case, the probability can be found as [tex]$P(Z < -0.5)$.[/tex] The probability is approximately 0.3085, or 30.85%.

Therefore, the probability that a randomly selected student has a midterm mark less than 75 is 0.3085 or 30.85%.

b) To find the probability that a class of 20 students has an average midterm mark less than 75:

Since the population is normally distributed, the sampling distribution of the sample mean will also be normally distributed. The mean of the sampling distribution is equal.

the population mean [tex]($\mu = 78$)[/tex], and the standard deviation of the sampling distribution (also known as the standard error) is equal to the population standard deviation divided by the square root of the sample size [tex]($\sigma / \sqrt{n}$).[/tex]

[tex]For a class of 20 students, the standard error is $\sigma / \sqrt{20} = 6 / \sqrt{20} \approx 1.342$.We can standardize the value of 75 using the z-score formula:\begin{align*}z &= \frac{x - \mu}{\sigma / \sqrt{n}} \\&= \frac{75 - 78}{1.342} \\&= -2.236\end{align*}[/tex]

Using a standard normal distribution table or a calculator, we can find the corresponding probability. In this case, the probability can be found as [tex]$P(Z < -2.236)$.[/tex]

The probability is approximately 0.0122, or 1.22%.

Therefore, the probability that a class of 20 students has an average midterm mark less than 75 is 0.0122 or 1.22%.

(x + 1.5)² + (y + 3)² = 365 is the standard form for the equation of the circle with endpoints (−8,−10) and (5,4).

The endpoints of the diameter of a circle with a standard form of an equation (x−h)²+(y−k)2=r2 are (-8,-10) and (5,4).

To find the standard form, you can use the following steps:

Step 1: Determine the center of the circle using the midpoint formula.

To find the center of the circle, you can use the midpoint formula:

((x1 + x2)/2, (y1 + y2)/2), where

(x1, y1) and (x2, y2) are the endpoints of the diameter.

Therefore,

((-8 + 5)/2, (-10 + 4)/2) = (-1.5, -3)

So the center of the circle is (-1.5, -3).

Step 2: Determine the radius of the circle using the distance formula.

To find the radius of the circle, you can use the distance formula:

d = √((x2 - x1)² + (y2 - y1)²), where (x1, y1) and (x2, y2) are the endpoints of the diameter.

Therefore, d = √((5 - (-8))² + (4 - (-10))²)

= √((13)² + (14)²)

= √(169 + 196) = √365

So the radius of the circle is √365.

Step 3:

Write the standard form of the equation of the circle.

The standard form of the equation of a circle with center (h, k) and radius r is:

(x - h)² + (y - k)² = r²

So, substituting the center and radius of the circle, we have:  

(x + 1.5)² + (y + 3)² = 365.

This is the standard form for the equation of the circle.
