Step-by-step explanation:

The expected value of the continuous random variable V is 5. The expected value of V is 5, indicating that, on average, we expect the value of V to be around 5.

To calculate the expected value of a continuous random variable V with a given probability density function (PDF), we integrate the product of V and the PDF over its entire range.

The PDF of V is defined as:

f(v) = 6/24 = 0.25 for 3 ≤ v ≤ 7, and 0 otherwise.

The expected value of V, denoted as E(V), can be calculated as:

E(V) = ∫v * f(v) dv

To find the expected value, we integrate v * f(v) over the range where the PDF is non-zero, which is 3 to 7.

E(V) = ∫v * (0.25) dv, with the limits of integration from 3 to 7.

E(V) = (0.25) * ∫v dv, with the limits of integration from 3 to 7.

E(V) = (0.25) * [(v^2) / 2] evaluated from 3 to 7.

E(V) = (0.25) * [(7^2 / 2) - (3^2 / 2)].

E(V) = (0.25) * [(49 / 2) - (9 / 2)].

E(V) = (0.25) * (40 / 2).

E(V) = (0.25) * 20.

E(V) = 5.

Therefore, the expected value of the continuous random variable V is 5.

The expected value represents the average value or mean of the random variable V. It is the weighted average of all possible values of V, with each value weighted by its corresponding probability. In this case, the expected value of V is 5, indicating that, on average, we expect the value of V to be around 5.

The distance traveled by the passenger train and the cattle train is equal to the total distance between them, which is 960 miles. Let x be the time (in hours) traveled by the passenger train and cattle train. Then, the equation that represents this situation is:

55x + 65x = 960

Simplifying the left-hand side of the equation, we get:

120x = 960

Dividing both sides by 120, we get:

x = 8

Therefore, the correct equation is:

B - 65x - 55x = 960

The amount Nicole's mother owe her for babysitting is 9.48 dollars.

She ordered a volleyball for $9.75, a net for $29.99, and knee pads for $15.00.

Nicole's mother said that she would pay for the order on her credit card if Nicole gave her the money.

Nicole gave her mother $40.00 .

Her mother also applied the money that she owed Nicole for babysitting.

Nicole's mother then gave her back $5.26.

The amount Nicole's mother owe her for babysitting can be calculated as follows;

Therefore, the total amount for the order is

$9.75 + $29.99 + $15.00 = $54.74

let the money her mother owes her  =  x

Therefore,

x + 40 + 5.26 = 54.74

x = 54.74 - 40 - 5.26

x = 54.74 - 45.26

x = 9.48

Therefore, the amount Nicole's mother owe her for babysitting is 9.48 dollars.

Therefore, the correct option is (D).Answer in 120 wordsA complete graph is one in which each pair of distinct vertices is connected by a unique edge. The number of edges in a complete graph is determined by the number of vertices in the graph. To find the number of edges in a complete graph with n vertices, we must first consider the number of ways to choose two vertices from the set of n vertices. After that, we must connect those two vertices.

Each pair of vertices produces an edge in a complete graph, and since the edges are undirected, we must divide by two to avoid double-counting.

To determine the effect of the interaction of the number of pages and cover type on cost, a statistical analysis would need to be performed using data on the number of pages, cover type, and cost. The analysis would likely involve running a regression model that includes both the number of pages and cover type as predictor variables, as well as an interaction term between the two.

 To answer your question, the effect of the interaction between the number of pages and cover type on the cost can be determined through a step-by-step process:

1. Identify the base cost of each cover type (e.g., hardcover, paperback, etc.).
2. Determine the cost per additional page for each cover type.
3. Calculate the cost for a specific number of pages and cover type by adding the base cost and the cost of additional pages.

For example:
- Base cost for hardcover: $5.00
- Base cost for paperback: $3.00
- Cost per additional page for hardcover: $0.10
- Cost per additional page for paperback: $0.05

Now, let's say you want to find the cost of a 100-page hardcover book:

1. Start with the base cost of a hardcover: $5.00
2. Multiply the number of pages (100) by the cost per additional page for hardcover ($0.10): 100 * $0.10 = $10.00
3. Add the base cost and the cost of additional pages: $5.00 + $10.00 = $15.00

So, the cost of a 100-page hardcover book is $15.00.

ANSWER

140 minutes

EXPLANATION

To find how long will it take for them to both pass the starting point at the same time, if one person completes the track in 28 minutes and the other completes it in 35 minutes, we have to find the lowest common multiple (LCM) of these two numbers.

To find the LCM, we can use the prime factorization method. First, write the prime factors of both numbers,

Then, multiply all the prime factors as many times as they occur most often. If a factor occurs the same number of times in both numbers, then we only write it once. In this case,

Hence, it will take 140 minutes for both runners to pass the starting point at the same time.

It's 28.

So first, you need to calculate the rate of change, or slope, for each of the equations. You also need to put each of them into equation form, using the y=mx+b formula, but you can't do that without knowing the slope, or rate of change. Please note, the rate of change in this answer will be referred to as slope and the initial value will be referred to as y-intercept.

For the first one, the equation is already written for you. The slope in the equation  is 5/2, or 2.5 in decimal form.

For the second one, we start at knowing 0=1, so the y intercept is 1. So then we see that 1=3/2, or 1.5 in decimal form. So, we just find the difference between 1 and 1.5, which is 0.5. We can now write our equation, y=0.5x+1.

The third one is the hardest one to calculate. We see the initial value, or the y intercept is 2. So far we have y=mx+2. Now, we have to figure out the slope, or rate of change. So, we see that 0=2. Now, let's look at another point in the graph. We'll do 2,5 since it is a clear point. So, here, the y value is 5. Let's subtract 5-2, and we get 3. However, we are not done. Because we chose a clear point in the graph to compare, we jumped 2 x spaces ahead, not one. So, now we divide by 2 to equal that out. So, 5/2=1.5. The slope is 1.5. Now, we have our equation, y=1.5x+2.

Now, we just compare our slopes, or rate of change to each other to find the greatest. We have 2.5, 0.5 and 1.5. 2.5 is the greatest. That was the first one. Now, it is asking us what the y value would be if x equals 10. So, we can just plug in 10 where x is in the equation. So, y=10x2.5+3. 10x2.5=25 and then plus 3 is 28. So, that is your answer.

I hope this helps you answer the problem.
