Answer:

\(8i^{22}\) - 1

Explanation:

It's actually quite easy to tell which simplifies to a real number without working out the problem.

\(i^{2}\) = -1

Any imaginary number with an even exponent is simplified to a real number. If it has an odd exponent, it cannot be simplified to a real number.

Some tips for fully solving the expression:

If the exponent is divisible by 4, then don't change the sign of the coefficient. You're just multiplying it by 1 because \(i^{4}\) = \((i^{2})^{2}\) = \((-1)^{2}\) = 1

If the exponent is divisible by 2, change the sign of the coefficient because you're multiplying it by -1.

Given: 2PQ = PR

Prove: Q is the midpoint of line PR

Statement: 2PQ = PQ + QR

Step-by-step explanation:

If Q is the midpoint of PR then

PR = PQ + QR [by segment addition postulate]

2PQ = PR [given]

2PQ = PQ + QR

2PQ-PQ = PQ + QR-PQ [by subtracting PQ from both sides]

PQ = QR

\( \because\) Q lies on PR and PQ = QR

\( \therefore\) Q is the midpoint of PR

A simple linear regression model is appropriate when the response variable is influenced by only one explanatory variable.

A simple linear regression model assumes a linear relationship between the response variable (y) and a single explanatory variable (x).

It is suitable when we want to understand how changes in the explanatory variable affect the response variable.

In the given options, the situation where the response variable y is influenced by one explanatory variable aligns with the requirements of a simple linear regression model.

This means that the relationship between y and x can be adequately described by a straight line.

The model aims to estimate the slope and intercept of this line, allowing us to make predictions and draw conclusions about the impact of the explanatory variable on the response variable.

If the response variable y is influenced by two or more explanatory variables, a multiple linear regression model would be more appropriate.

Multiple linear regression allows for the analysis of the combined effects of multiple predictors on the response variable, accounting for their individual contributions.

Similarly, if the explanatory variable x is influenced by two or more response variables, a different modeling technique, such as multivariate regression, would be more suitable.

Therefore, the situation where the response variable y is influenced by one explanatory variable is the scenario where a simple linear regression model is appropriate.

Answer:

12000

Step-by-step explanation:

Using this information, you can make a ratio: 12.2/50 = x/48744

By simplifying this ratio you get that 50x = 594676. Dividing both sides by 50 you get about 11900, which you can round up to 12000

Answer:

11,894 women

Step-by-step explanation:

ratio of women to employees = 12.2 : 50

Let x = number of women employees to 48744 employees

12.2 : 50 = x : 48744

⇒ 12.2 / 50 = x / 48744

⇒ 0.244 = x / 48744

⇒ x = 0.244 · 48744

⇒ x = 11893.536

⇒ x = 11894 (nearest whole number)

Therefore, there are approximately 11,894 women in a company with a total of 48,744 employees

The one mean Z test can be used for small samples of size less than 15 when the population standard deviation is known.

The one-mean z-test is a hypothesis test that is used to test a hypothesis about the mean of a population when the population standard deviation is known, and the sample size is large (typically greater than 30).

When the sample size is small (less than 15), the one-mean z-test is not appropriate because the assumptions of the test may not be met.

When the sample size is small, we typically use a t-test instead of a z-test to test a hypothesis about the population mean.

Specifically, we use a one-sample t-test when the population standard deviation is unknown, and the sample size is small (typically less than 30).

The one-sample t-test uses a t-distribution to calculate the p-value and test the null hypothesis about the population mean.

It is important to note that the sample size of 15 is not a hard and fast rule for when to switch from the z-test to the t-test.

The decision of which test to use depends on the specific context and the assumptions of the test.

In general, if the population standard deviation is unknown and the sample size is small (less than 30), then we use the t-test. If the population standard deviation is known and the sample size is large (greater than 30), then we use the z-test.

What is meant by equation?

An equation is a mathematical statement that uses symbols to show that two expressions are equal. It typically contains variables, coefficients, and mathematical operations such as addition, subtraction, multiplication, and division.

What is meant by table?

A table is a set of data arranged in rows and columns, typically used to organize and present information in a structured and easy-to-read format. Tables can be used to store and display various types of data.

According to the given information

To write an equation to model the data, we can use the formula for direct variation:

y = kx

where k is the constant of variation.

To find k, we can use any of the pairs of values in the table. Let's use the first pair:

y = 0.4, x = 2

0.4 = k * 2

k = 0.2

Now that we have k, we can write the equation:

y = 0.2x

Therefore, the equation that models the data in the table is y = 0.2x.

We are asked to find the first four nonzero terms in a power series expansion about Xo for a general solution to the given differential equation, 4x^2y" - y' + y = 0, with Xo = 1. The expression will be in terms of a_0 and a_1, and it will include all terms up to order 3.

To find the power series expansion of a general solution to the given differential equation, we assume that the solution can be expressed as a power series in terms of (x - Xo), where Xo is the given value. Let's denote the general solution as y(x) = Σ a_n(x - Xo)^n, where Σ represents the summation symbol and a_n are coefficients.

Next, we substitute this power series into the differential equation and equate the coefficients of like powers of (x - Xo) to zero. This will generate a recursion relation for the coefficients a_n.

By solving the recursion relation, we can determine the values of the coefficients a_n. We need to find the first four nonzero terms, so we will solve for a_0, a_1, a_2, and a_3.

Once the coefficients are determined, we can write the expression for y(x) by including all terms up to order 3. The expression will involve a_0, a_1, and (x - Xo) raised to different powers corresponding to the coefficients.

Therefore, by solving the differential equation and determining the coefficients using the power series method, we can express the general solution up to the fourth nonzero term in terms of a_0, a_1, and the powers of (x - Xo) up to order 3.

For a binomial random variable with = 10 and = 0.4 P(X = 4) is ≈ 0.2508, P(X ≥ 4) is ≈ 0.6513, P(X > 4) ≈ 0.4756, P(X ≤ 4) ≈ 0.3487, E(X) = np = 10 * 0.4 = 4 and σ(X) is ≈ 1.55

Given,

X is a binomial random variable with n = 10 and p = 0.4.

a) P(X = 4) can be calculated using the probability mass function of the binomial distribution:

P(X = 4) = (10 choose 4) * 0.4^4 * 0.6^6 ≈ 0.2508

b) P(X ≥ 4) can be calculated using the cumulative distribution function of the binomial distribution:

P(X ≥ 4) = 1 - P(X < 4) = 1 - P(X = 0) - P(X = 1) - P(X = 2) - P(X = 3)

Using the probability mass function, we get:

P(X ≥ 4) ≈ 0.6513

c) P(X > 4) can be calculated as:

P(X > 4) = P(X ≥ 5) = 1 - P(X < 5) = 1 - P(X = 0) - P(X = 1) - P(X = 2) - P(X = 3) - P(X = 4)

Using the probability mass function, we get:

P(X > 4) ≈ 0.4756

d) P(X ≤ 4) can be calculated using the cumulative distribution function of the binomial distribution

P(X ≤ 4) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4)

Using the probability mass function, we get:

P(X ≤ 4) ≈ 0.3487

e) The expected value of a binomial random variable is given by np, so:

E(X) = np = 10 * 0.4 = 4

f) The standard deviation of a binomial random variable is given by √(np(1-p)), so:

σ(X) = √(np(1-p)) = √(10 * 0.4 * 0.6) ≈ 1.55

On the basis of given data & Using combining-functions, We can say that

a).The function P(x) which represents the price of a ticket can we given by where x represents the number of 0.75 price decreases= ($15 - 0.75x)

b). the function T(x) which represents number of tickets sold on a day

=(180 + 10x)

c). the revenue would be if the magician decides to sell the tickets for

$12 =  $ 2640

The process of composition, in which the result of one function becomes the input of another, allows us to create complex functions from basic ones. A complicated function may occasionally need to be broken down into two or more simpler ones, using the opposite method.

Given that:

Current price of ticket = $15

Average tickets sold per day = 180

Price decrease each time = $0.75

Number of price decreases = x

Total Price decrease = 0.75x

Increase in number of tickets with price decrease each time = 10

Total increase in number of tickets with x times price decrease = 10x

a). Function to represent total price of tickets

P(x) = current price - total price decrease  

      = ($15 - 0.75x)

Function to represent number of tickets T(x)

= average number of tickets+ total increase in tickets

= (180 + 10x)

b)Function to represent total revenue R(x) = total tickets x total price

                                                                      = T(x) . P(x)

                                                                      = (180 + 10x) ($15 - 0.75x)

c)Given that total price of tickets=$12

                                            P(x)=$12

                             ($15 - 0.75x) = $12

                                      - 0.75x  =  $12 - $15

                                       - 0.75x  =  - $3

                                              x = 3 ÷ 0.75

                                              x = 4 times

The number of times price decreased=4

Total tickets sold T(x) =(180 + 10x)

                                  =(180 + 10(4))

                                  =180+40

                                   =220 tickets

Total revenue= T(x) . P(x)
