For Question 22:
To calculate the Page Rank of node B after 2 iterations, we need to use the formula:
PR(x) = (1-d) + d(Σ PR(y)/O(y))
where PR(y) is the Page Rank of node y and O(y) is the number of outgoing links from node y.

After the first iteration, the Page Rank of each node is:
PR(A) = 0.16, PR(B) = 0.29, PR(C) = 0.26, PR(D) = 0.29

So, for node B:
PR(B) = (1-0.9) + 0.9((PR(A)/1) + (PR(C)/2) + (PR(D)/1))
= 0.1 + 0.9(0.16/1 + 0.26/2 + 0.29/1)
= 0.1 + 0.9(0.16 + 0.13 + 0.29)
= 0.1 + 0.9(0.58)
= 0.52

After the second iteration, we need to use the updated Page Rank values to calculate the new values. So, after the first iteration, the Page Rank of each node is:
PR(A) = 0.11, PR(B) = 0.52, PR(C) = 0.28, PR(D) = 0.29

So, for node B:
PR(B) = (1-0.9) + 0.9((PR(A)/1) + (PR(C)/2) + (PR(D)/1))
= 0.1 + 0.9(0.11/1 + 0.28/2 + 0.29/1)
= 0.1 + 0.9(0.11 + 0.14 + 0.29)
= 0.1 + 0.9(0.54)
= 0.55

Therefore, the Page Rank of node B after 2 iterations is 0.55.

For Question 23:
To calculate the authoritativeness and hubness scores for node A, we need to use the formulas:
a(x) = Σh(y) and h(x) = Σa(y)
where h(y) is the hubness score of node y and a(y) is the authoritativeness score of node y.

In the very beginning, all nodes have an equal score of 1. So, for node A:
a(A) = h(A) = 1

Therefore, the authoritativeness and hubness scores for node A in the very beginning are both 1.

For Question 24:
To calculate the hubness score of node D after 2 iterations, we need to use the formula:
h(x) = Σa(y)*z(y,x)
where a(y) is the authoritativeness score of node y and z(y,x) is 1 if there is a link from node y to node x, otherwise it is 0.

After the first iteration, the authoritativeness scores are:
a(A) = 0.11, a(B) = 0.52, a(C) = 0.28, a(D) = 0.09

And the hubness scores are:
h(A) = 0.11, h(B) = 0.28, h(C) = 0.52, h(D) = 0.09

So, for node D:
h(D) = (a(A)*z(A,D)) + (a(B)*z(B,D)) + (a(C)*z(C,D)) + (a(D)*z(D,D))
= (0.11*0) + (0.52*1) + (0.28*0) + (0.09*1)
= 0.61

After the second iteration, the updated authoritativeness scores are:
a(A) = 0.07, a(B) = 0.38, a(C) = 0.27, a(D) = 0.28

And the updated hubness scores are:
h(A) = 0.07, h(B) = 0.29, h(C) = 0.45, h(D) = 0.19

So, for node D:
h(D) = (a(A)*z(A,D)) + (a(B)*z(B,D)) + (a(C)*z(C,D)) + (a(D)*z(D,D))
= (0.07*0) + (0.38*1) + (0.27*0) + (0.28*1)
= 0.66

Therefore, the hubness score of node D after 2 iterations is 0.66.
Question 22:
For the Page Rank of node B after 2 iterations, we use the formula: PR(x) = (1-d) + d * Σ(PR(y)/O(y)), where d=0.9, and O(y) is the number of outgoing links from y.

Without knowing the specific network structure and initial Page Rank values, I cannot provide the exact Page Rank for node B after 2 iterations.

Question 23:
In the beginning, the authoritativeness (a) and hubness (h) scores for node A are initialized. Generally, they are initialized as 1 for each node.

So, for node A:
a(A) = 1
h(A) = 1

Question 24:
For the hubness score of node D after 2 iterations, we need to update the initial hubness score twice using the formula: h(x) = Σ(a(y)), where x has a link to y.

Similar to Question 22, without knowing the specific network structure and initial authoritativeness values, I cannot provide the exact hubness score for node D after 2 iterations.

Let's simplify the expression step by step: Expand the squared term:

(x - 3y)² = (x - 3y)(x - 3y) = x² - 6xy + 9y²

Expand the second term:

3(x + y)(x − 4y) = 3(x² - 4xy + xy - 4y²) = 3(x² - 3xy - 4y²)

Expand the third term:

x(3x + 4y + 3) = 3x² + 4xy + 3x

Now, let's combine all the expanded terms:

(x - 3y)² + 3(x + y)(x − 4y) + x(3x + 4y + 3)

= x² - 6xy + 9y² + 3(x² - 3xy - 4y²) + 3x² + 4xy + 3x

Combining like terms:

= x² + 3x² + 3x² - 6xy - 3xy + 4xy + 9y² - 4y² + 3x

= 7x² - 5xy + 5y² + 3x

The extent to which the researcher can refer that findings with a sample from which it was drawn is referred to as generalizability.

Generalizability refers to the ability to extrapolate study findings from a sample to the entire population. It also refers to the capacity to apply findings from one study to a similar environment in a different investigation.

Generalizability and transferability are two research traits that are related. When considering generalizability in research, there are two features or dimensions to consider: generalizability as it relates to the specific population on which the research is conducted, and generalizability on a global scale.

Such studies will be easier to generalize if the researcher uses adequate sampling approaches, sample sizes, and exact processes.

In general, a study has strong generalizability when the findings apply to a wide range of persons or situations. The study has weak generalizability if the results can only be applied to a subset of the population or in a very specific circumstance.

The required graph has been attached below that represents the function y = 2 cos (x + π/4).

The cosine function has a range of values between -1 and 1, and it is a periodic function that repeats every 2π radians or 360 degrees. The graph of the cosine function is a wave-like curve that oscillates between -1 and 1, with a period of 2π radians or 360 degrees.

To plot the graph of the function y = 2 cos (x + π/4), we can follow these steps:

The coefficient of the cosine term is 2, so the amplitude is 2.

The coefficient of the angle x is 1, so the period is 2π.

The constant term is π/4, so the phase shift is -π/4.

The y-intercept occurs when x = 0, which gives y = 2 cos (π/4) = √2.

Using the amplitude, period, phase shift, and intercepts, sketch the graph of the function over one period. Then, repeat the graph every 2π to get the complete graph.

Not more than 5 outfits

Step-by-step explanation:

Given

\(Total = \$760\)

\(New\ Bicycle = \$239.70\)

\(Reflector (3) = \$18.63\) (each)

\(Glove = \$30.79\)

First, we calculate the amount left.

\(Amount = Total - (New\ Bicycle + Reflector * 3 + Glove)\)

\(Amount = \$760 - (\$239.70 + \$18.63 * 3 + \$30.79)\)

\(Amount = \$760 - (\$239.70 + \$55.89 + \$30.79)\)

\(Amount = \$760 - (\$326.38)\)

\(Amount = \$760 - \$326.38\)

\(Amount = \$433.62\)

An outfit costs $78.84 and he plans to buy x outfits.

The inequality is represented as follows:

\(\$78.84 * x \leq \$433.62\)

i.e. the amount to spend on outfits can't exceed $433.62

Divide both sides by $78.84

\(\frac{\$78.84 * x}{\$78.84} \leq \frac{\$433.62}{\$78.84}\)

\(x \leq \frac{\$433.62}{\$78.84}\)

\(x \leq \frac{433.62}{78.84}\)

\(x \leq 5.5\)

Since there is no 0.5 outfit, then She can only afford a maximum of 5 outfits to stay within budget.

The vector orthogonal for both vectors is \((20, -10, -4) / \sqrt{444}\) = (\(20 / \sqrt{444}\), \(-10 / \sqrt{444}\), \(-4 / \sqrt{444}\))

What is an orthogonal vector?

An orthogonal vector is a vector that is perpendicular to another vector in a given space. In other words, two vectors are orthogonal if their dot product is equal to zero.

To find a vector orthogonal to both 2, 2, 0 and 0, 2, 5 of the form 1, we can take the cross product of the two vectors, which results in a vector that is orthogonal to both. The cross product of 2, 2, 0 and 0, 2, 5 is given by:

(2, 2, 0) x (0, 2, 5) = (20, -10, -4)

So, a vector orthogonal to both 2, 2, 0 and 0, 2, 5 is given by (20, -10, -4). We can normalize this vector by dividing it by its magnitude, which is equal to sqrt(20^2 + (-10)^2 + (-4)^2) = sqrt(444). The normalized vector will be of the form 1:

\((20, -10, -4) / \sqrt{444}\) = (\(20 / \sqrt{444}\), \(-10 / \sqrt{444}\), \(-4 / \sqrt{444}\))

Hence, the vector orthogonal for both vectors is \((20, -10, -4) / \sqrt{444}\) = (\(20 / \sqrt{444}\), \(-10 / \sqrt{444}\), \(-4 / \sqrt{444}\)).

The circumference of the lid of a water bottle with a circle layer and a radius of 0.5 inches can be calculated using the formula C = 2πr, where C represents the circumference and r represents the radius. The area of the lid can be calculated using the formula A = πr^2, where A represents the area.

Now, let's explain the calculation in more detail:

Circumference:

Using the formula C = 2πr, where r = 0.5 inches and π is approximately 3.14, we can calculate the circumference:

C = 2πr = 2 * 3.14 * 0.5 = 3.14 inches.

Area:

Using the formula A = πr^2, where r = 0.5 inches and π is approximately 3.14, we can calculate the area:

A = πr^2 = 3.14 * (0.5)^2 = 3.14 * 0.25 = 0.79 square inches.
