The value of x is -4.

We have,

(3x + 25) and (6x - 2) makes one angle.

So,

(9x + 23) is the angle.

Now,

It is bisected in two angles.

So,

9x + 23 = 1/2 x (6x - 2)

9x + 23 = 3x - 1

9x - 3x = -1 - 23

6x = -24

x = -4

Thus,

The value of x is -4.

If X and Y are independent, continuous random variables, each with an even density function, and n is odd, then E(X+Y)^n=0.

Since X and Y are independent, the joint probability density function is simply the product of the individual density functions, i.e., f(x,y) = f(x) * f(y).

Now, consider the random variable Z = X + Y. The moment-generating function of Z is given by:

M(t) = E(e^(tZ)) = E(e^(t(X+Y))) = E(e^(tX) * e^(tY))

Since X and Y are independent, we can write:

M(t) = E(e^(tX)) * E(e^(tY))

Since both X and Y have even density functions, their moment-generating functions are symmetric about t=0, i.e., M_X(-t) = M_X(t) and M_Y(-t) = M_Y(t). Therefore, we have:

M(t) = M_X(t) * M_Y(t) = M_X(-t) * M_Y(-t) = M(-t)

Thus, the moment-generating function of Z is symmetric about t=0.

Now, since n is odd, (X+Y)^n will be an odd function, and so its moment-generating function will be zero at t=0. Therefore, we have:

E((X+Y)^n) = M^(n)(0) = 0

Therefore, we have shown that if X and Y are independent, continuous random variables, each with an even density function, and n is odd, then E(X+Y)^n=0

The mean amount spent on breakfast weekly is approximately $11.14, and the standard deviation is approximately $2.23.

To calculate the mean and standard deviation of the amount she spends on breakfast weekly (7 days), we need the individual daily expenditures data. Let's assume we have the following daily expenditure values in dollars: $10, $12, $15, $8, $9, $11, and $13.

To find the mean, we sum up all the daily expenditures and divide by the number of days:

Mean = (10 + 12 + 15 + 8 + 9 + 11 + 13) / 7 = 78 / 7 ≈ $11.14

The mean represents the average amount spent on breakfast per day.

To calculate the standard deviation, we need to follow these steps:

1. Calculate the difference between each daily expenditure and the mean.

  Differences: (-1.14, 0.86, 3.86, -3.14, -2.14, -0.14, 1.86)

2. Square each difference: (1.2996, 0.7396, 14.8996, 9.8596, 4.5796, 0.0196, 3.4596)

3. Calculate the sum of the squared differences: 34.8572

4. Divide the sum by the number of days (7): 34.8572 / 7 ≈ 4.98

5. Take the square root of the result to find the standard deviation: \(\sqrt{(4.98) }\)≈ $2.23 (rounded to the nearest cent)

The standard deviation measures the average amount of variation or dispersion from the mean. In this case, it tells us how much the daily expenditures on breakfast vary from the mean expenditure.

The probability that randomly selected mechanical component weighs: more than 11.5 lbf is 0.0099, less than 8.7 lbf is 0.3208,  less than 5.0 lbf is 0.0228, between 6.2 lbf and 7.0 lbf is 0.1314, between 10.3 lbf and 14.0 lbf is 0.0436, between 6.8 lbf and 8.9 lbf is 0.3464.

We can use the standard normal distribution and z-scores to answer these questions:

P(X > 11.5) = P(Z > (11.5 - 8) / 1.5) = P(Z > 2.33) = 0.0099

Therefore, the probability that a randomly selected mechanical component weighs more than 11.5 lbf is 0.0099, or about 1%.

P(X < 8.7) = P(Z < (8.7 - 8) / 1.5) = P(Z < 0.47) = 0.3208

Therefore, the probability that a randomly selected mechanical component weighs less than 8.7 lbf is 0.3208, or about 32%.

P(X < 5.0) = P(Z < (5 - 8) / 1.5) = P(Z < -2) = 0.0228

Therefore, the probability that a randomly selected mechanical component weighs less than 5.0 lbf is 0.0228, or about 2%.

P(6.2 < X < 7.0) = P((6.2 - 8) / 1.5 < Z < (7 - 8) / 1.5) = P(-1.2 < Z < -0.67) = 0.1314

Therefore, the probability that a randomly selected mechanical component weighs between 6.2 lbf and 7.0 lbf is 0.1314, or about 13%.

P(10.3 < X < 14.0) = P((10.3 - 8) / 1.5 < Z < (14 - 8) / 1.5) = P(1.53 < Z < 2.67) = 0.0436

Therefore, the probability that a randomly selected mechanical component weighs between 10.3 lbf and 14.0 lbf is 0.0436, or about 4%.

P(6.8 < X < 8.9) = P((6.8 - 8) / 1.5 < Z < (8.9 - 8) / 1.5) = P(-0.47 < Z < 0.60) = 0.3464

Therefore, the probability that a randomly selected mechanical component weighs between 6.8 lbf and 8.9 lbf is 0.3464, or about 35%.

 The total equity for Wonderpillow is £193,110.

Equity represents the residual interest in the assets of a business after deducting liabilities. To calculate the total equity, we need to subtract the total liabilities from the total assets.

Given:

Long-term liabilities = £100,000

Non-current assets = £289,770

Current assets = £124,400

Current liabilities - current assets = £3,340

First, we calculate the total liabilities:

Total liabilities = Long-term liabilities + (Current liabilities - current assets)

Total liabilities = £100,000 + (£3,340)

Total liabilities = £103,340

Next, we calculate the total equity:

Total equity = Total assets - Total liabilities

Total equity = Non-current assets + Current assets - Total liabilities

Total equity = £289,770 + £124,400 - £103,340

Total equity = £310,830 - £103,340

Total equity = £207,490

The sample mean of the weights at the birth of the randomly chosen infants is 7.6 pounds.

Given: The sample of seven infants was selected randomly and the weights are: {9.0, 7.3, 6.0, 8.8, 6.8, 8.4, and 6.6} (in pounds)

What is a sample?

A sample can be defined as a part of something big or a whole. It can be some of the elements from a given set of elements.

For example: Let us consider the set of natural numbers. The set of natural numbers has an infinite number of elements in it. We choose some numbers from the set, say {2, 7, 9, 10, 99, 200, 234}. These chosen numbers are known as samples from the set of natural numbers.

What is the sample mean?

The sample mean is the average value of the samples or it is the mean of all the elements which exist in the given sample.

The sample mean is denoted by x⁻ which is pronounced as x bar.

The formula to calculate sample mean (x⁻) is:

Sample Mean (x⁻) = Summation of all the elements in the sample / Total number of elements in the sample.

x⁻ = ∑xₙ / n

where,

∑xₙ = Summation of all the elements in the sample

n = Total number of elements in the sample

x⁻ = Sample mean

Now let's solve the given question:

The given sample is {9.0, 7.3, 6.0, 8.8, 6.8, 8.4, and 6.6}

The summation of the elements in the sample is:

∑xₙ = 9.0 + 7.3 + 6.0 + 8.8 + 6.8 + 8.4 + 6.6

∑xₙ = 52.9

The total number of elements in the sample is:

n = 7

Therefore, the sample mean (x⁻) is:

x⁻ = ∑xₙ / n

x⁻ = 52.9 / 7

x⁻ = 7.5571 ≈ 7.6

Hence the sample mean of the weights at the birth of the randomly chosen infants is 7.6 pounds.

The lines do not intersect, and they are not skew (since skew lines cannot be parallel).

To determine whether the lines intersect, are skew, or are parallel, we need to find out if there is a point that lies on both lines. If such a point exists, then the lines intersect. If not, then we need to check whether the lines are parallel or skew.

To find out if there is a point that lies on both lines, we need to solve the system of three equations that results from equating the corresponding components of the two lines:

\(= > 10+3 t &= -7+4 s \ 18+5 t &\\= > -11+7 s \ 9+2 t &= -7+5 s\)

We can rewrite this system in matrix form as:

\($$\begin{pmatrix}3 & -4 \\\ 5 & -7\\ \ 2 & -5\end{pmatrix}\begin{pmatrix}t \ s\end{pmatrix}=\begin{pmatrix}-17 \ 7 \ 16\end{pmatrix}$$\)

We can solve this system by row-reducing the augmented matrix:

\($$\left(\begin{array}{cc|c} 3 & -4 & -17\\ \ 5 & -7 & 7\\ \ 2 & -5 & 16 \end{array}\right)$$\)

Using elementary row operations, we can transform this matrix into the row-reduced echelon form:

\($$\left(\begin{array}{cc|c} 1 & -2 & 5 \\\ 0 & 1 & 2 \\\ 0 & 0 & 0 \end{array}\right)$$\)

This system has infinitely many solutions, which means that the lines are parallel. Therefore, the lines do not intersect, and they are not skew (since skew lines cannot be parallel).
