Answer:

\(x=13\)

Step-by-step explanation:

The angle on a straight line is always 180 degrees.

Thus,

\((12x-26)+50=180\)

Remove the brackets:

\(12x-26+50=180\)

\(12x+24=180\)

Subtract 24 from both sides:

\(12x+24-24=180-24\)

\(12x=156\)

Divide both sides by 12:

\(\frac{12x}{12}=\frac{156}{12}\\\)

\(x=13\)

There are 25 possible outcomes where we either get a blue die 3 or an even sum or both.

To solve this problem, we need to use the concept of probability. Probability is the likelihood of an event occurring, expressed as a number between 0 and 1. In this case, we want to find the probability of rolling either a blue die 3 or an even sum or both.

First, let's count the number of outcomes where the blue die is 3. There is only one way to get a 3 on the blue die, and the red die can be any number from 1 to 6. Therefore, there are 6 possible outcomes where the blue die is 3.

Next, let's count the number of outcomes where we get an even sum. There are three ways to get an even sum: (1,1), (2,2), and (3,3). For each of these outcomes, the blue die can be any number from 1 to 6. Therefore, there are 18 possible outcomes where we get an even sum.

Finally, let's count the number of outcomes where we get both a blue die 3 and an even sum. There is only one way to get a blue die 3 and an even sum: (3,3). Therefore, there is only one possible outcome where we get both a blue die 3 and an even sum.

To find the total number of outcomes that have either a blue die 3 or an even sum or both, we need to add the number of outcomes where the blue die is 3, the number of outcomes where we get an even sum, and the number of outcomes where we get both. This gives us:

6 + 18 + 1 = 25

Therefore, there are 25 possible outcomes where we either get a blue die 3 or an even sum or both.

The probability that cards # 1, # 2, and # 3 are still in order on the top of the stack is 0.045%.

Step-by-step explanation:

Since a politician is about to give a campaign speech and is holding a stack of thirteen cue cards, of which the first 3 are the most important, and just before the speech, she drops all of the cards and picks them up in a random order, to determine what is the probability that cards # 1, # 2, and # 3 are still in order on the top of the stack, the following calculation must be performed:

1/13 x 1/13 x 1/13 = X

0.076 x 0.076 x 0.076 = X

0.00045 = X

0.00045 x 100 = 0.045

Therefore, the probability that cards # 1, # 2, and # 3 are still in order on the top of the stack is 0.045%.

The total cost of renting a DVD includes a $15 membership fee and an additional $2 rental fee per video rented every month. This means that each month, a member will be charged $17 for one rented video, $19 for two rented videos, $21 for three rented videos, and so on.

The membership fee is a one-time cost that allows the member to have access to the rental service. The rental fee is a recurring cost that is charged based on the number of videos rented each month. It is important for members to keep track of the number of videos rented in order to budget accordingly. Additionally, members should also consider the value they are getting from the rental service compared to the cost. If a member is renting multiple videos each month, the cost may be worth it. However, if they are only renting a few videos, they may want to consider other options or a different membership plan that better suits their needs.
To find the total cost of renting a DVD, you'll need to take into account both the membership fee and the rental fee per video rented every month.
1. First, consider the membership fee, which is $15. This is a one-time cost you need to pay to become a member.
2. Next, determine the number of videos rented every month. Let's represent this number as "x."
3. Calculate the rental fee for the videos rented each month by multiplying the number of videos (x) by the rental fee per video, which is $2. So, the monthly rental cost will be 2x.
4. To find the total cost (C) of renting DVDs, add the membership fee and the monthly rental cost together:

The random circumstance in this case is whether or not a flight from one of the top 18 U.S. airlines arrives on time. Let's denote this random circumstance as "A." The associated probability, given that 77.6% of flights arrived on time, can be represented as P(A) = 0.776 or 77.6%.

Let's clarify the representation of the random circumstance and associated probability based on the given information.

The random circumstance in this case is whether or not a flight from one of the top 18 U.S. airlines arrives on time. Let's denote this random circumstance as event "A." The associated probability, given that 77.6% of flights arrived on time, can be represented as P(A) = 0.776 or 77.6%.

To explain in more detail, let's consider a large sample of domestic flights flown by the top 18 U.S. airlines in January of that certain year. Each flight in this sample can be seen as a random trial, where the outcome is whether the flight arrives on time or not.

In this context, event A represents the specific outcome of a flight arriving on time, and the complementary event, denoted as event "A'", represents the outcome of a flight being delayed or not arriving on time.

The given information states that 77.6% of domestic flights arrived on time. Therefore, the associated probability P(A) represents the probability of a flight from one of the top 18 U.S. airlines being on time, and it is equal to 0.776 or 77.6%.

It's important to note that this probability represents an average value based on historical data and may vary from month to month or between different airlines. Additionally, this probability assumes that each flight's on-time performance is independent of the others, which may not always hold true in practice.

Overall, the random circumstance "A" refers to a flight from one of the top 18 U.S. airlines arriving on time, and the associated probability P(A) represents the likelihood of this occurrence based on the given information.

distribute

1/5 * 15 + 1/5 * 10k

3 + 2k

Answer:

3 + 2k

Step-by-step explanation:

First, I am going to explain what the distributive property is. Lets say he had the expression a(b + c). We can "distribute" the a to the b and c:

a(b + c) = ab + ac

We can apply the distributive property to the expression 1/5(15 + 10k):

1/5(15 + 10k)

= (1/5)(15) + (1/5)(10k)

= 3 + 2k

By using the distributive property, we found the expression 3 + 2k.

Cosine distance is used in the k-means clustering algorithm to remove outliers. It is a metric used to determine the similarity between two documents. In k-means clustering, cosine distance is used to calculate the distance between data points.

Cosine distance is used to normalize the data so that it is not affected by the length of the data vectors or the scale of the data. The cosine distance is calculated as follows:

Cosine distance = 1 - Cosine similarity,

where Cosine similarity = dot product of two vectors/ product of the magnitude of two vectors.

To remove the outliers from the k-means clustering algorithm, we can set a threshold value for the cosine distance. If the cosine distance between two data points is greater than the threshold value, then those data points are considered outliers and they are not included in the cluster. This helps to ensure that the clustering algorithm only groups together data points that are similar and ignores the outliers.

Answer:

Step-by-step explanation:

The expected value of the random variable X, with the given probability mass function \(\[f(x) = \frac{3}{2} \cdot x^{\frac{1}{3}}, \quad x = 0, 1, 2, 3, \ldots\]\) is approximately 2.47.

To calculate the expected value of a random variable, you need to sum the product of each possible value of the random variable and its corresponding probability. In this case, we have a discrete random variable X with the probability mass function:

\(\[f(x) = \frac{3}{2} \cdot x^{\frac{1}{3}}, \quad x = 0, 1, 2, 3, \ldots\]\)

To find the expected value of X, denoted as E(X), we compute:

E(X) = Σ [x * f(x)]

Let's calculate it step by step:

E(X) = 0 * f(0) + 1 * f(1) + 2 * f(2) + 3 * f(3) + ...

Substituting the given probability mass function:\(\[E(X) = 0 \cdot \left(\frac{3}{2} \cdot 0^{\frac{1}{3}}\right) + 1 \cdot \left(\frac{3}{2} \cdot 1^{\frac{1}{3}}\right) + 2 \cdot \left(\frac{3}{2} \cdot 2^{\frac{1}{3}}\right) + 3 \cdot \left(\frac{3}{2} \cdot 3^{\frac{1}{3}}\right) + \ldots\]\)

Simplifying further:

\(\[E(X) = 0 + \frac{3}{2} \cdot 1^{\frac{1}{3}} + \frac{3}{2} \cdot 2^{\frac{1}{3}} + \frac{3}{2} \cdot 3^{\frac{1}{3}} + \ldots\]\)

Now, let's calculate each term:

\(\[E(X) = \frac{3}{2} \cdot 1^{\frac{1}{3}} + \frac{3}{2} \cdot 2^{\frac{1}{3}} + \frac{3}{2} \cdot 3^{\frac{1}{3}} + \ldots\]\)

To evaluate each term, we use the following values:

\(1^{(1/3)} = 1,\\2^{(1/3) }= 1.26,\\3^{(1/3) }= 1.44\), and so on.

E(X) = (3/2) * 1 + (3/2) * 1.26 + (3/2) * 1.44 + ...

Evaluating each term:

E(X) ≈ (3/2) + (3/2) * 1.26 + (3/2) * 1.44 + ...

Now, we can calculate the expected value by summing up the terms or approximating the sum. Let's approximate the sum using a partial sum. Suppose we sum up to n terms:

E(X) ≈ (3/2) + (3/2) * 1.26 + (3/2) * 1.44 + ... + (3/2) * nth_term

To get a reasonably accurate approximation, we choose a value for n. Let's say n = 10. We then calculate:

E(X) ≈ (3/2) + (3/2) * 1.26 + (3/2) * 1.44 + ... + (3/2) * 10th_term

After evaluating this expression, you'll obtain the approximate value of the expected value of X.
