The factor in the Salk vaccine experiment is the type of injection, which is the independent variable that was manipulated in the experiment to determine its effect on the dependent variable, which is the presence or absence of polio.

The factor in the Salk vaccine experiment is the type of injection, which is either the vaccine or the placebo. This is the independent variable, which is the factor that is being manipulated in the experiment to determine its effect on the dependent variable, which is the presence or absence of polio.

The students were randomly assigned to either the vaccine or placebo injection group, which is an important aspect of the experiment to control for any potential confounding variables. This randomization helps to ensure that any observed differences between the vaccine and placebo groups are due to the type of injection received and not due to any other factors, such as differences in age, gender, or health status.

During the school year, all students were observed for evidence of polio, which is the dependent variable. The purpose of the experiment was to determine whether the vaccine was effective in preventing polio, so the presence or absence of polio is the outcome measure that was used to evaluate the effectiveness of the vaccine.

Answer:4

Step-by-step explanation:

A) First, let's calculate the probability of selecting a defective chip as the second chip:

Probability (defective chip as the second chip) = (Number of defective chips / Total number of chips) * (Number of defective chips - 1 / Total number of chips - 1)

Number of defective chips = 26

Total number of chips = 105

Probability of selecting a defective chip as the second chip = (26 / 105) * (25 / 104)

Probability of second chip being defective ≈ (26 / 105) * (25 / 104) ≈ 0.0601

Therefore, the probability that the second chip selected is defective is approximately 0.0601.

B) First, let's calculate the probability of selecting a defective chip on the first draw:

Probability of selecting a defective chip on the first draw = Number of defective chips / Total number of chips

       = 26 / 105

Now, since we are selecting without replacement, the number of defective chips and the total number of chips decrease by 1 for the second draw.

                         = 25 / 104

                          = 24 / 103

Probability of all three chips being defective ≈ (26 / 105) * (25 / 104) * (24 / 103) ≈ 0.0057

Therefore, the probability that all three chips selected are defective is approximately 0.0057.

We are given a boxplot and a histogram of the number of colds patients had experienced over the last year.

Let us analyze each of the given statements.

Statement 1: Both displays show the data is skewed right.

The above statement is correct.

Notice that the peak of the histogram is at 2 and the long tail of values is to the right of the peak.

Hence, the histogram is skewed right.

Now, notice the boxplot, the whisker is longer on the right side of the box.

Hence, the distribution of the boxplot is skewed right.

Statement 2: Both displays show the data is skewed left.

The above statement is incorrect. (because statement 1 is correct)

Statement 3: Only the histogram indicates the number of patients in the sample.

The above statement is correct.

You can calculate the total number of patients in the sample by adding up the heights of all bars in the histogram.

On the other hand, there is no indication of the number of patients in the boxplot.

Statement 4: The box plot shows the mean number of colds was 2.

The above statement is incorrect because a box plot gives us the median value, not the mean.

Statement 5: The box plot shows the median number of colds was 2.

The above statement is correct.

The median of the box plot is the middle value of the box which is exactly 2.

Hence, the median of the box plot is 2.

Summary:

Statements 1, 3, and 5 are correct.

Dijkstra's algorithm calculates the shortest path from vertex 7 to all other vertices in the graph, forming a tree structure where vertex 7 is the root.

Dijkstra's algorithm is a graph traversal algorithm used to find the shortest path between two vertices in a weighted graph. To find the sink tree rooted at vertex 7, we can apply Dijkstra's algorithm starting from vertex 7. The algorithm proceeds by iteratively selecting the vertex with the smallest distance from the current set of vertices and updating the distances to its adjacent vertices.

Starting from vertex 7, we initialize the distance of vertex 7 as 0 and the distances of all other vertices as infinity. Then, we explore the adjacent vertices of vertex 7 and update their distances accordingly. We repeat this process, selecting the vertex with the smallest distance each time, until we have visited all vertices in the graph.

The result of applying Dijkstra's algorithm to find the sink tree rooted at vertex 7 is a tree structure that represents the shortest paths from vertex 7 to all other vertices in the graph. Each vertex in the tree is connected to its parent vertex, forming a directed acyclic graph. This sink tree provides a clear visualization of the shortest paths and their corresponding distances from vertex 7 to each vertex in the graph.

Therefore, approximately 1,491 Whos will be infected 10 days after the virus is first detected.

To approximate the number of Whos that will be infected 10 days after the virus is first detected, we can use the concept of exponential growth. We can use the formula for exponential growth:\(P(t) = P0 * (1 + r)^t,\) where P(t) is the population at time t, P0 is the initial population, r is the growth rate, and t is the time in days.

Let's calculate the growth rate (r) first:

r = (800 - 100) / 5

= 140 Whos per day

Now, we can calculate the approximate number of infected Whos 10 days later:

\(P(10) = 100 * (1 + 140/100)^{10\)

Using a calculator, we can compute this value:

\(P(10) ≈ 100 * (1.4)^{10\)

Answer:

The shaded region of A is 12.5% of the area of B.

Step-by-step explanation:

Although the side of square A is 50% of the side of square B, if you think about things logically here square A is only 25%of square B. Therefore the shaded area HAS to be half of 25% making the answer 12.5%

Answer:

12.5%

Step-by-step explanation:

Since it given that the length of the sie of a square A is 50% of the  length of the side of square B. As well as given us the question we need to find the answer to which is:

Express the area of the shaded region of square A as a percentage of the area of square B.

What we need:

Area of shaded region of Square A as a % of Area of Square B

Now we can solve but first :

Let "b" be the side length of Square B

Let "a" be the side length of Square A

As well as:

It given side length of Square A (a) = 50% (1/2) of side length of Square B (b), therefore we have,

a = ½b

Area of a square = s², where s is the  side length

Area of Square A = (½b)² = b²/4

Area of Square B = b²

Finding the area of the shaded region of the Square A = ½ of area of Square A.

Area of shaded region of Square A = ½*(b²/4) = b²/8

Expressing the area of the shaded portion of square A as a percentage of are of Square B:

Area of shaded portion of Square A ÷ Area of Square B × 100%

Solving:

⇒ \(\frac{\frac{b^2}{8}}{b^2}\times100\)

⇒\(\frac{b^2}{8}\times\frac{1}{b^2}\times100\)

⇒ \(\frac{b^2\times1}{8\timesb^2}\times100\)

⇒ \(\frac{b^2}{8\times b^2}\times100\)

⇒ \(\frac{1}{8}\times100=12.5\)

Base on the solving above we can conclude that:

The area of the shaded region of Square A is 12.5% of the area of Square B.

a) The controllable state space realization is A = [[0, 1], [-8, -6]], B = [[1], [1]], C = [1, 2], and D = 0.

b) The system is controllable.

c) The system is observable.

d) The kernel of the transient matrix [s1-4]' is [0, 0]'.

a) To find the controllable state space realization, we need to express the transfer function in the general state space form:

G(s) = C(sI - A)^(-1)B + D

where A, B, C, and D are matrices.

First, let's factorize the denominator of the transfer function:

s^2 + 6s + 8 = (s + 2)(s + 4)

This gives us the eigenvalues of the system: λ1 = -2 and λ2 = -4.

Now, we can construct the A matrix:

A = [[0, 1],

    [-8, -6]]

Next, we construct the B matrix using the numerator coefficients:

B = [[1],

    [1]]

Then, the C matrix can be obtained from the coefficients of the numerator:

C = [1, 2]

Finally, the D matrix is zero in this case:

D = 0

Therefore, the controllable state space realization is:

A = [[0, 1],

    [-8, -6]]

B = [[1],

    [1]]

C = [1, 2]

D = 0

b) The controllability of the system can be determined by checking the controllability matrix:

Qc = [B, AB]

Qc = [[1, 1],

     [-6, -14]]

The system is controllable if the rank of the controllability matrix is equal to the number of states. In this case, the rank of Qc is 2, and we have 2 states, so the system is controllable.

c) The observability of the system can be determined by checking the observability matrix:

Qo = [[C],

     [CA]]

Qo = [[1, 2],

     [-14, -32]]

The system is observable if the rank of the observability matrix is equal to the number of states. In this case, the rank of Qo is 2, and we have 2 states, so the system is observable.

d) The kernel of the transient matrix is the set of vectors x such that (sI - A)x = 0. Let's solve this equation:

[s - 0   1] [x1] = [0]

[-8  s + 6] [x2]   [0]

From the first row, we have x2 = 0. Substituting this into the second row, we get -8x1 + (s + 6)x2 = 0. Since x2 = 0, we have -8x1 = 0, which implies x1 = 0.

Therefore, the kernel of the transient matrix is [0, 0]'.

Step-by-step explanation:

there are approximately 34 boys in the introductory geology course.

To determine the number of boys in the introductory geology course, we need to calculate the ratio of boys to girls and use the total number of students enrolled.

The given ratio states that there are six boys for every five girls. This can be expressed as 6 boys : 5 girls.

Let's assume the number of boys in the course is represented by B and the number of girls is represented by G.

According to the given information, we can set up the following equation:

6 boys / 5 girls = B / G.

Since the total number of students enrolled in the course is 374, we can write another equation:

B + G = 374.

To solve these equations simultaneously, we can use the concept of proportion.

From the first equation, we can rewrite it as:

6G = 5B.

Now we can substitute this expression into the second equation:

B + G = 374

5B + 6B = 374

11B = 374

B = 374 / 11

B ≈ 34.

A continuous random variable is a variable that can take any value within a certain range or interval. In contrast, a discrete random variable can only take on certain specific values.

In the context of houses, the number of bedrooms is an example of a discrete random variable, since a house can only have a whole number of bedrooms (1, 2, 3, etc.). Similarly, the zip code of a house is also a discrete random variable, since zip codes are predetermined and finite.

On the other hand, the square footage of a house is an example of a continuous random variable. This is because the square footage of a house can take on any value within a certain range (e.g. from 500 to 5000 square feet). There is no specific value that the square footage must be - it can be any number within that range.

To summarize, the square footage of a house is an example of a continuous random variable because it can take on any number within a certain range, whereas the number of bedrooms and zip code are examples of discrete random variables since they can only take on specific, predetermined values.
