The function available capacity for the four classes is 40 seats each. The protection level for class 1 is 40 seats, meaning that 40 seats are protected for class 1. 40 + 40 + 40 + 40 = 160

The booking limits for the four fare classes in a flight are given as 40, 40, 40, and 40, respectively. This means that the available capacity for these four classes is 40 seats each. The protection level for class 1 is 40 seats, meaning that 40 seats are specifically reserved for passengers in class 1. This ensures that passengers in class 1 are guaranteed at least 40 seats on the flight. The protection level for the other classes is also 40 seats each, ensuring that at least 40 seats are available for each class. This allows airlines to ensure that all of their classes have sufficient seating capacity for their passengers. 40 + 40 + 40 + 40 = 160

The most appropriate choice for unitary method will be given by-

a) Mass of 100 \(cm^3\) of the material = 1000 g

b) Mass of 500 \(cm^3\) of the material = 5000 g

What is unitary method?

Unitary method is the process in which the value of single unit can be calculated from the value of multiple unit and the value of multiple unit can be calculated from the value of single unit.
Sometimes Value of single unit can be less than the value of multiple unit. For example - The relation between the cost of a commodity and the quantity of the commodity

Sometimes Value of single unit can be more than the value of multiple unit. For example - The relation between the number of men and the number of days taken by those men to do a certain job.

Here,

a)Mass of \(9 cm^3\) of samples = 90 g

Mass of 1 \(cm^3\) of sample = \(\frac{90}{9}\) g

Mass of 1 \(cm^3\) of sample = 10 g

Mass of 100 \(cm^3\) of sample = \(10 \times 100 g\) = 1000 g

b) Mass of 500 \(cm^3\) of sample = \(10 \times 500\) g = 5000 g

Women make up 64% of the sample and are typically the household's main investment.

There is a correlation between American women and being the main provider in their home.

Descriptive statistics, also known as brief informative coefficients, are used to summarize a specific data collection, which may be a sample of a population or a representation of the entire population. Descriptive statistics include measures of variability and central tendency (spread). Measures of central tendency include the mean, median, and mode, whereas measures of variability include the standard deviation, variance, minimum and maximum variables, kurtosis, and skewness.

For instance, the sum of the following data set is 20: (2, 3, 4, 5, 6). A 4 (20/5) is the mean. A data set's mode is the number that appears most frequently, while its median is the value that is in the middle of the range of values. It is the value that separates a data set's higher values from lower values. There are many less common ways to use descriptive statistics, but they are nevertheless essential.

The box's dimensions are 7.5 m by 0.5 m by 4.5 m.

V(x) = x3 + 2x2 - 11x - 12

To factor, you want 3 numbers that multiply to give -12 (the constant term) and add to give 2 (coefficient of the x2 term).  The answer is 4, -3, and 1: (4)(-3)(1) = -12, 4 + (-3) + 1 = 2.  So the volume polynomial factors to:

V(x) = (x+4)(x-3)(x+1)

Now the volume of a rectangular box is:

V = Length*Width*Height = (x+4)(x-3)(x+1)

So let's pick height = (x+1) = 4.5  (you could pick any one of the three factors).

x+1 = 4.5

x = 3.5

Length = (x+4) = 3.5+4 = 7.5

Width = (x-3) = 3.5 - 3 = 0.5

The box's dimensions are 7.5 m by 0.5 m by 4.5 m.

The cost of one pen is $3.5 and one ruler is $2

Represent pen with x, and rulers with y.

So, the equations are:

To solve for x and y, we start by multiplying the second equation by 2

\(2(2x + 7y = 21)\)

\(4x + 14y = 42\)

Subtract \(4x + 5y = 24\) from \(4x + 14y = 42\)

\(4x - 4x + 14y - 5y = 42 - 24\)

Simplify the expression

\(9y = 18\)

Divide both sides by 9

\(y = 2\)

Substitute 2 for y in \(2x + 7y = 21\)

\(2x + 7(2) = 21\)

This gives

\(2x + 14 = 21\)

Collect like terms

\(2x = 21 -14\)

Evaluate like terms

\(2x = 7\)

Divide both sides by 2

\(x = 3.5\)

Hence, the cost of one pen is $3.5 and one ruler is $2

The appropriate regression model depends on the stationarity properties of both the dependent and independent variables, as well as the error term. The researcher can use a standard OLS regression model with first-order differencing of both Y and X.

In the first scenario, both Y and X are I(0), which means they are stationary time series. In this case, the researcher can perform a standard linear regression analysis, as the stationary series would lead to a stable long-run relationship. The answer from this model will be reliable and less likely to suffer from spurious regressions. In the second scenario, Y is I(2) and X is I(0). This implies that Y is integrated of order 2 and X is stationary. In this case, the researcher should first difference Y twice to make it stationary before performing a regression analysis. However, this approach might not be ideal as the integration orders differ, which can lead to biased results.

In the third scenario, Y and X are both I(1) and the error term is I(0). This indicates that both Y and X are non-stationary time series, but their combination might be stationary. The researcher should employ a co-integration analysis, such as the Engle-Granger method or Johansen test, to identify if there is a stable long-run relationship between Y and X. If co-integration is found, then an error correction model can be used for more accurate predictions.

In a vaulted church, each rectangular division of space, consisting of one groin vault, is called a bay. A bay is a section of the church that is defined by the vertical and horizontal supports of the building, creating a rectangular space with one groin vault as the ceiling. These bays can vary in size and shape depending on the architectural style of the church. The groin vaults are created by the intersection of two barrel vaults, creating a more complex and ornate design than a simple barrel vault.These vaults distribute the weight of the roof to the supporting walls, allowing for larger, more open spaces and the inclusion of windows for natural light. Bays can be found in various religious and secular buildings, and their arrangement helps create an organized and harmonious architectural composition. By dividing the space into bays, architects can create a rhythm within the structure, enhancing its overall aesthetic appeal and functional efficiency.

The use of groin vaults in church architecture allowed for a greater sense of height and space, as well as the ability to create intricate designs and patterns on the ceiling. Overall, the bays and groin vaults in a vaulted church are an important aspect of the architectural style and design of the building, providing a sense of grandeur and beauty to those who visit.

The results obtained by central limit theorem are given below-

μ = 170 customers per day

σ = 45 customers per day

n = 31

\(\begin{aligned}&\mu_{x}=170 \\&\sigma_{x}=8\end{aligned}\)

The Central Limit Theorem proves that the distribution of a sample means of size n can be estimated to the normal distribution with mean  (μ) and standard deviation (σ) for one random normally distributed variable X, with mean (μ) and standard deviation (σ);

\(s=\frac{\sigma}{\sqrt{n}}\)

This Central Limit Theorem may also be applied to skewed variables if n is at least 30.

She observes that the rival business averages 170 clients per day, with a standard deviation of 45 clients.

Thus, \(\mu=170, \sigma=45\)

Let's say she selects a random sampling of 31 days.

So, n = 31

Now, the mean is according to the Central Limit Theorem is

\(\mu_{x}=170\), and

standard deviation = \(\sigma_{x}=\frac{45}{\sqrt{31}}=8\)

Therefore, by using central limit theorem the data is obtained as,

μ = 170 customers per day

σ = 45 customers per day

n = 31

Sharon bought 72 buttons out of which 54 are large. So the percentage of buttons which are large is 75 %.

Percentage is the value that can be stated as a fraction of 100. Percentage is calculated by the equation,

Percentage = (Number of favored item/ Number of total items) × 100

Sharon bought a total of 72 buttons. She counted that 54 out of them are large.

So the fraction = Number of large buttons/Number of buttons in total

                        = 54/72

So the percentage = (54÷72)×100 = 75%.

Percent of remaining buttons = [(72-52)÷72]/100 = 25%

There is enough proof to indicate that the percentage of newsletter readers who possess a Rolls Royce is less than 69%.

The null hypothesis is that p = 0.69, meaning that 69% of the newsletter readers own a Rolls Royce. The alternative hypothesis is that p < 0.69, meaning that less than 69% of the newsletter readers own a Rolls Royce.

We can use a one-tailed z-test to test the hypothesis. Assuming a sample size of n = 100, if we observe fewer than 69 Rolls Royces in our sample, we can reject the null hypothesis.

Using a z-test, we can calculate the z-score by using the formula:

z = (p' - p) / sqrt(p * (1 - p) / n)

where p' is the sample proportion, p is the hypothesized proportion, and n is the sample size.

At a significance level of 0.10, the critical z-value is -1.28. If the calculated z-score is less than -1.28, we can reject the null hypothesis.

If we conduct a survey of 100 newsletter readers and find that 58 of them own a Rolls Royce, the sample proportion would be p' = 0.58. Calculating the z-score, we get:

z = (0.58 - 0.69) / sqrt(0.69 * 0.31 / 100) = -1.83

Since -1.83 is less than -1.28, we can reject the null hypothesis and conclude that there is sufficient evidence to suggest that fewer than 69% of the newsletter readers own a Rolls Royce.
