The two dice do not need to be identical. If it is possible, do it. If it is not possible, prove that it is not possible.

Some hints I got were to try to construct a pair of nonstandard dice such that the generating function for their sum matches the corresponding g.f. for a pair of standard dice and to note that the g.f. for a pair of standard dice can be factored quite a bit (you can reduce it to factors of degree 2 or less).

Answer:

\( \frac{x}{4} + \frac{1}{2} = \frac{1}{8} \)

\( \frac{x}{4} = - \frac{3}{8} \)

\(x = - \frac{3}{2} = - 1 \frac{1}{2} \)

The solution to the equation x/4 + 1/2 = 1/8 is x = -3/2.

Consider the equation, we have only one x term, so taking all the terms without x to the other side and terms with x on one side.

x/4 + 1/2 = 1/8

Take the 1/2 term on the other side,

x/4=1/8 - 1/2

Taking the LCM on the Right side,

x/4 = (1-4) / 8

x/4 = -3/8

Now, we have x/4 so what we can do is, shift the 4 to the other side too, we get,

x = ( -3/8) * 4

x = -3/2

The solution to the equation x/4 + 1/2 = 1/8 is x = -3/2.

The point on the curve x^2 + 2y = 0 that is closest to the point (0, -1/2) occurs when y = -1/4.

To find the point on the curve that is closest to the given point, we need to find the distance between the two points. We can use the distance formula, which is given by:

d = sqrt((x2 - x1)^2 + (y2 - y1)^2)

In this case, the two points are (0, -1/2) and (x, y), where (x, y) lies on the curve x^2 + 2y = 0. So we can write:

d = sqrt((x - 0)^2 + (y + 1/2)^2)

We want to minimize this distance, so we can take the derivative of d with respect to x and set it equal to 0:

d' = 0

(x - 0) + 2(y + 1/2)y' = 0

x + y' + y'y + 1 = 0

We can solve for y' using the equation x^2 + 2y = 0:

y' = -x/2

Now we can substitute this into the equation we found for y':

x + y' + y'y + 1 = 0

x - x/2 + y(-x/2) + 1 = 0

y = -1/4

So the point on the curve that is closest to the given point is (x, y) = (0, -1/4).

The Poisson distribution is applied to events where the probability of occurrence of a certain number of events in a fixed interval of time, space, or distance is small but not necessarily "very small". False.

The Poisson distribution is used to model events that occur randomly and independently over a continuous or discrete interval of time, space, or distance, such as the number of phone calls received at a call center in an hour, the number of cars passing through a toll booth in a given time period, or the number of emails received per day. The Poisson distribution is characterized by a discrete probability mass function that describes the probability of a certain number of events occurring in a given interval, and it is widely used in probability theory and statistics for modeling events with low to moderate occurrence rates.

The poisson distribution is applied to events for which the probability of occurrence over a given span of time, space, or distance is very small.

Given statement is False.

Because, The Poisson distribution is applied to events for which the probability of occurrence over a given span of time, space, or distance is not necessarily very small, but rather where the events occur randomly and independently at a constant average rate.

The Poisson distribution models the number of events that occur in a fixed time interval or within a certain area or volume of space, assuming that the events occur independently of each other and at a constant average rate. It is used in many fields, such as biology, physics, economics, and engineering, to model the occurrence of rare or common events.

The Poisson distribution has several important properties, including:

Its mean is equal to λ, and its variance is also equal to λ.

It is a discrete distribution, meaning that it models only whole numbers of events.

It is often used to model rare or unusual events, but can also be used for events that occur frequently, as long as they occur independently at a constant average rate.

\((9\pi - 18)cm^2\)

Step-by-step explanation:

To find the area of this section of the triangle, we will have to find the area of the sector, and then subtract the area of the triangle. To first find the area of the sector of the circle. Remember that the sector of a circle can be found using a proportion of angles. Since there is an angle of 90 degrees in the center. We will take that and divide it by 360 degrees, which is an entire circle. \(\frac{90}{360} = \frac{1}{4}\), so the sector is one-quarter of the entire circle. Now find the area of the entire circle which will be \(\pi r^{2}\)× \(\frac{1}{4}\), where r is 6 since it is the radius of the circle. So therefore the area of the sectore will be a quarter of 36\(\pi\), which is 9\(\pi\).

Now you must find the area of the triangle with side length 6. Remember, this is an isosceles triangle with sides length of 6 because two of the sides are radii. Also, remember that this is a 90 degree triangle, so the area of the triangle is simply \(\frac{6*6}{2}\), which is 18 cm^2.

Now to find the area of just the yellow segment, just take the area of the sector we found, and subtract the area of the triangle. Therefore, the answer is \((9\pi - 18)cm^2\)

The probabilities are given as follows -

A) P(X = 11) = 2/36

B) P(X ≤ 6) = 5/12

The probability mass function for the sum X of the two dice is given by table A. See same attached.

The cumulative mass function (CMF) for X is given by the cumulative sum of the probabilities in the probability mass function is given by table B. See same attached.

To draw the probability mass function and the cumulative mass function, we can plot the values of P(X) and P(X <= x) against X, respectively.

The probability of getting a even value is computed as follows

P(X is even) = P(X = 2) + P(X = 4) + P(X = 6) + P(X = 8) + P(X = 10) + P(X = 12)

= 1/36 + 3/36 + 5/36 + 5/36 + 3/36 + 1/36

= 18/36

P(X is even) = 1/2

The probability that for a single roll of the two dice, the sum of the dots is equal to 11   P(X = 11) = 2/36

= 1/18

The probability of obtaining a value of 6 or less is  P(X < = 6) = P(X = 2) + P(X = 3) + P(X = 4) + P(X = 5) + P(X = 6)

= 1/36 + 2/36 + 3/36 + 4/36 + 5/36

Mr. Nguyen bought a package of 3 chicken legs and a package of 7 chicken wings. Ms. Dawes bought a package of 3 chicken legs and a package of 6 chicken wings. Mr. Nguyen bought 45 ounces of chicken. Ms. Dawes bought 42 ounces of chicken. How much did each chicken leg and each chicken wing weigh?​

Answer:

Weight of Chicken leg = x = 8 ounces

Weight of Chicken wing = y = 3 ounces

Step-by-step explanation:

Let us represent

Weight of Chicken leg = x

Weight of Chicken wing = y

Mr. Nguyen bought a package of 3 chicken legs and a package of 7 chicken wings.Mr. Nguyen bought 45 ounces of chicken.

3x + 7y = 45 ounces.... Equation 1

Ms. Dawes bought a package of 3 chicken legs and a package of 6 chicken wings. Ms. Dawes bought 42 ounces of chicken.

3x + 6y = 42 ounces... Equation 2

Combining both Equations together we solve by Elimination method

3x + 7y = 45.... Equation 1

3x + 6y = 42... Equation 2

We eliminate x by subtracting Equation 2 from Equation 1

Hence:

y = 3 ounces

Solving for x

3x + 6y = 42 ounces... Equation 2

3x +6(3) = 42 ounces

3x + 18 = 42 ounces

3x =( 42 - 18) ounces

3x = 24 ounces

x = 24 ounces/3

x = 8 ounces

Hence:

Weight of Chicken leg = x = 8 ounces

Weight of Chicken wing = y = 3 ounces

Answer:

chicken leg- 8 oz

chicken wing- 3 oz

If you need to reduce the number of predictors due to software limitations or clarity of presentation, you should choose a variable that has a strong relationship with the target variable and contributes the most to the overall model's accuracy.

This can be determined through feature selection techniques, such as recursive feature elimination or feature importance ranking, based on your specific dataset and problem.

To avoid overfitting, set the minimum number of records in a terminal node to 50. Also, set the maximum number of levels to be displayed at seven (the maximum allowed in XL Miner).

Write down the results in terms of rules. The classification tree using all predictors and the best-pruned tree are given below:

Best-pruned Tree Classification Tree Rules: If (credit score ≤ 642.5) AND (income ≤ 35.5) AND (age ≤ 52.5)

then Predict Default = yes If (credit score ≤ 642.5) AND (income ≤ 35.5) AND (age > 52.5)

then Predict Default = yes If (credit score ≤ 642.5) AND (income > 35.5) then Predict Default = no If (credit score > 642.5) AND (income ≤ 81.5) AND (age ≤ 25.5)

then Predict Default = yes If (credit score > 642.5) AND (income ≤ 81.5) AND (age > 25.5) AND (age ≤ 47.5)

then Predict Default = no If (credit score > 642.5) AND (income ≤ 81.5) AND (age > 25.5) AND (age > 47.5)

then Predict Default = no If (credit score > 642.5) AND (income > 81.5) AND (credit score ≤ 684.5)

then Predict Default = yes If (credit score > 642.5) AND (income > 81.5) AND (credit score > 684.5) AND (income ≤ 96.5) then Predict Default = yes If (credit score > 642.5) AND (income > 81.5) AND (credit score > 684.5) AND (income > 96.5)

then Predict Default = no If the number of predictors were to be reduced due to software limitations or for clarity of presentation, then the best variable to choose for prediction would depend on the correlation between the predictors and the response variable.

To fit a classification tree using variables and avoid overfitting, you should set the minimum number of records in a terminal node to 50 and limit the maximum number of levels displayed to seven. After fitting the tree and pruning it, you will have a set of rules based on the chosen predictors.

The number of degrees for each part of the museum visitors graph would be Age 18 and under: 108 degrees, Age 19 – 44: 180 degrees, Age 45 – 64: 54 degrees, and Age 65 and over: 18 degrees.

To find the number of degrees for each part of the museum visitors graph, we need to know the total number of visitors for that month. Let's assume that the total number of visitors for the month is 10,000.

Age 18 and under:

Let's assume that the number of visitors aged 18 and under is 3,000. To find the number of degrees for this section of the graph, we need to use the formula: (Number of visitors in the age group / Total number of visitors) x 360 degrees. So, (3000/10000) x 360 = 108 degrees.

Age 19 – 44:

Let's assume that the number of visitors aged 19-44 is 5,000. Using the same formula as above, we get (5000/10000) x 360 = 180 degrees.

Age 45 – 64:

Let's assume that the number of visitors aged 45-64 is 1,500. Using the same formula as above, we get (1500/10000) x 360 = 54 degrees.

Age 65 and over:
