-$217,400 is the amount of money needed to cover the purchase of your new home by selling the old house at $389,000.

Cost of home = $264,000

Selling price = $389,000

Purchase price of new home = $428,000

Deposit percentage = 20%

The total amount received from selling the house is:

The amount received from the sale = selling price - purchase price

The amount received from sale = $389,000 - $264,000

Amount received from sale = $125,000

The amount spent on the new home is:

Amount spent on new home = purchase price - deposit

Amount spent on new home = $428,000 - 20% of $428,000

Amount spent on new home = $428,000 - $85,600

Amount spent on new home = $342,400

Finally, the leftover money is calculated as:

The amount left over = amount received from sale - the amount spent on a new home

The amount left over = $125,000 - $342,400

Amount left over = -$217,400

The negative amount indicates that you did not have enough money from the sale of your old home to cover the purchase of your new home.

In this problem, we are provided with a data set. To solve this problem, we have to construct a scatter plot, find the correlation coefficient and its critical value at α=0.05, and then test the hypothesis \(H0: ρ=0\) against \(Ha: ρ≠0.\)

Below are the steps to solve this problem:

Step 1: Construct a scatter plotThe scatter plot for the given data is shown below:

Step 2: Find the correlation coefficientUsing a calculator, we can find the correlation coefficient as follows:

We get \(r ≈ 0.816\)

Step 3: Find the critical value for correlation coefficientAt \(α=0.05\), the critical values of correlation coefficient are -0.632 and 0.632.

We need to find the critical value for two-tailed test. Since \(α = 0.05\) is a level of significance, the confidence level is \(1 - α = 0.95\).

The critical value for two-tailed test is 0.632.

Step 4: Test the hypothesis Hypothesis:\(H0: ρ=0Ha: ρ≠0\)The test statistic is given \(byz = [ln(1 + r) - ln(1 - r)] / 2\)

We have\(r = 0.816, soz = [ln(1 + 0.816) - ln(1 - 0.816)] / 2 ≈ 3.018\)The critical value for two-tailed test is 0.632. Since the absolute value of the test statistic is greater than the critical value, we reject the null hypothesis. Thus, we conclude that there is significant evidence to suggest that there is a linear relationship between X and Y.

The given statement "A and B are n x n matrices. The determinant of A is the product of the diagonal entries in A" is False because the product of the diagonal entries in A for n x n matrix will not be equal to determinant of A.

The determinant of a matrix is a scalar value that can be calculated using a specific formula. The formula for finding the determinant of an n x n matrix involves finding the sum of products of the elements in certain combinations of rows and columns.

The product of the diagonal entries is only one element in the calculation of the determinant of a matrix, and it is not equal to the determinant unless the matrix has all zeros except on the diagonal.

For example, consider the following 2x2 matrices:

A = [2 3; 4 5]

B = [1 0; 0 1]

The determinant of A is (25) - (34) = -2

The product of the diagonal entries in A is 2*5 = 10, which is not equal to the determinant.

The determinant of B is (11) - (00) = 1

The product of the diagonal entries in B is 1*1 = 1, which is equal to the determinant.

Therefore, the statement "The determinant of A is the product of the diagonal entries in A" is false in general, and the determinant of a matrix is typically calculated using a more involved formula that takes into account all the elements in the matrix.

Their annual state income tax could be $4050  if there is $2,000 deduction for married couples and $900 for each dependent or child.

What is percentage?

percentage can be defined as the product of ratio of given value , total value and hundred.

Given,

The Cabrera family makes $92,800 annually and has 2 children. The state in which they live allows a $2,000 deduction for married couples and $900 for each dependent or child. The tax rate is 4.8%.  

As it is a family so $2,000 deduction for married couples

and they are having two childs so we will deduct another $1800 .

so now the actual amount  = $92800 - $2000 - $1800

Amount = $90000

The tax rate = 4.5%

that is amount to be paid = 4.5 % of 90000

= 4.5 / 100  *  90000

= 45/1000  *  90000

= 45 * 90

= 4050

Hence, Their annual state income tax could be $4050 .

Step-by-step explanation:

To gain 10% profit, the shopkeeper must offer a 8.33% discount on the market price.

Profit is the difference between the total revenue and total cost of a business. It is an important measure of the success of a business, as it shows how much money the business is making from its operations. Profit is usually expressed as a percentage of the total revenue. It is also known as "net income" or "net profit" and is the amount of money left over after all expenses, including taxes, have been paid. Profit is important because it allows a business to reinvest in itself, expand, and grow. It can also be used to pay dividends to shareholders, increase wages, and cover other expenses.

To gain 10% profit, the shopkeeper must offer a 8.33% discount on the market price. This is because if the shopkeeper was gaining 20% before, a 10% discount would reduce the profit he is making to 10%.

Lets 20% gain = $20

Then market price be = 120/100 = $120

10% gain = $110

Discount = $120 -  $110

               = $10

Discount % = 10/120

                  = 0.083

                  = 8.33%

Thus, To gain 10% profit, the shopkeeper must offer a 8.33% discount on the market price.

The mean of the deviation scores in any data distribution is also known by research scientists as the mean deviation or the average deviation. It is a measure of the average distance of each data point from the mean of the distribution.

The mean deviation is calculated by finding the absolute difference between each data point and the mean, adding up these differences, and dividing by the number of data points. Unlike the standard deviation, the mean deviation gives equal weight to each data point and is less affected by outliers.

However, it is not as commonly used as the standard deviation because it does not have the same statistical properties and is not as easily interpreted in terms of probability distributions.

34 years would it take for the value of the account to reach $11, 620 by using compounding.

Compounding is the process through which earnings from an asset, such as interest or capital gains, are reinvested to produce more earnings over time. The investment will produce earnings from both its initial principal and the accumulated earnings from prior periods, resulting in this growth, which was computed using exponential functions.

The first statement tells you the account balance can be modeled by

A = 610 x \(2^{\frac{t}{6}\)

Here t is in years

We want to find t when A = 11620

11620 = 610x(\(2^{\frac{t}{6}\))

Divide by 610

19.05 = \(2^{\frac{t}{8}\)

Take logarithm

log(19.05) = (t/8)log(2)

t = 8·log(19.05)/log(2)

≈34

It would take about 34 years for the value to reach $11620.

a. The alternative hypothesis (H1) specifies that is greater than 26, indicating a directed alternative, this is a one-tailed test.

b. The alternative hypothesis is one-sided and argues that > 26, hence the critical value is 1.645.

c. The value of the test statistic (z-score) is z ≈ 3.82.

d. We reject the null hypothesis (H0) because the test statistic (z = 3.82) is higher than the crucial value (1.645).

In this case, the p-value is the probability of observing a sample mean of 28 or greater, assuming the population mean is 26.

a. This is a one-tailed test because the alternative hypothesis (H1) states that μ is greater than 26, indicating a directional alternative.

b. The decision rule for a one-tailed test at a significance level of 0.05 is to reject the null hypothesis (H0) if the test statistic is greater than the critical value. In this case, the critical value is 1.645 because the alternative hypothesis is one-sided and states that μ > 26.

c. The value of the test statistic (z-score) can be calculated using the formula:

z = (x - μ) / (σ / √n)

where x is the sample mean, μ is the population mean, σ is the population standard deviation, and n is the sample size.

In this case:

x = 28

μ = 26

σ = 4

n = 34

Substituting the values into the formula:

z = (28 - 26) / (4 / √34) ≈ 3.82

d. Since the test statistic (z = 3.82) is greater than the critical value (1.645), we reject the null hypothesis (H0).

e-1. To calculate the p-value, we need to find the area under the standard normal distribution curve to the right of the test statistic (z = 3.82). We can use a standard normal distribution table or a calculator to find this area.

The p-value is the probability of observing a test statistic as extreme as the one calculated (or more extreme) under the null hypothesis.

e-2. Interpreting the p-value: The p-value represents the probability of obtaining a sample mean as extreme as the one observed (or more extreme) if the null hypothesis is true.

The type of sampling described, where the researchers intentionally select a sample with 50% straight and 50% LGBTQ+ respondents, is known as "disproportionate stratified sampling."

A. Disproportionate stratified sampling involves dividing the population into different groups (strata) based on certain characteristics and then intentionally selecting a different proportion of individuals from each group. In this case, the researchers are dividing the population based on sexual orientation (straight and LGBTQ+) and selecting an equal proportion from each group.

B. Availability sampling (also known as convenience sampling) refers to selecting individuals who are readily available or convenient for the researcher. This type of sampling does not guarantee representative or unbiased results and may introduce bias into the study.

C. Snowball sampling involves starting with a small number of participants who meet certain criteria and then asking them to refer other potential participants who also meet the criteria. This sampling method is often used when the target population is difficult to reach or identify, such as in hidden or marginalized communities.

D. Simple random sampling involves randomly selecting individuals from the population without any specific stratification or deliberate imbalance. Each individual in the population has an equal chance of being selected.

Given the description provided, the sampling method of intentionally selecting 50% straight and 50% LGBTQ+ respondents represents disproportionate stratified sampling.

Answer:

y = 9

Step-by-step explanation:

it's perpendicular to x = 8 which is a vertical line, so our line will be horizontal line with slope 0 and it goes through (6,9) so at x = 6, y =9

but since the line is horizontal, (slope = 0) it must have the same y-value at all x- points so,

the equation is y = 9

The equation is :

Solution:

If two lines are perpendicular, their slopes are opposite reciprocals of each other.

Since we have a vertical line, its slope is undefined. Now, remember the definition of perpendicular lines. They intersect at a right angle.

And the line that is perpendicular to a vertical line is a horizontal line, which has a slope of 0.

Lines with 0 slope have the appearance of y = b where b is the y intercept.

Now there are two ways to find the y-intercept, which are :

Allow me to demonstrate the first one.

Method 1. Point slope

Point slope is \(\bf{y-y_1=m(x-x_1)}\).

Plugging in the numbers \(\bf{y-9=0(x-6)}\)

Simplifying \(\bf{y-9=0}\)

Simplifying further

\(\bf{y=9}\)

The branch of statistics that deals with the organization and summarization of collected information is called Descriptive Statistics.

Descriptive Statistics involves the methods and techniques used to describe and summarize data in a meaningful way, providing insights and understanding about the characteristics of the data set.

In Descriptive Statistics, the focus is on organizing, presenting, and summarizing data through various measures such as central tendency (mean, median, mode), dispersion (range, variance, standard deviation), and graphical representations (histograms, bar charts, pie charts).

It aims to provide a concise and informative summary of the data, allowing researchers or analysts to gain a better understanding of the data set and draw meaningful conclusions.

Descriptive Statistics plays a crucial role in the initial stages of statistical analysis by providing a clear and concise overview of the data, enabling researchers to identify patterns, trends, and important features of the data set. It serves as a foundation for further statistical analysis and helps in making informed decisions based on the collected information.
