Answer:

The amount she saves is 25% of her income

Step-by-step explanation:

She is paid $11 per hour

She works 9 hours per day

and for 24 days per month

So, she works 9(24) hours per month

= 216 hours per month

Now, she is paid $11 hourly, so for 216 hours,

she will have 11(216) = $2376

Total income = $2376 per month

Saving = $594 per month

As a percentage, we divide the savings by the total income,

savings/(total income) = 594/2376 = 1/4 = 0.25

Hence we get 25%

Step-by-step explanation:

200 x (1 + 0.325%)^9 - 1 / 0.325%

200 x (1 + 0.00325)^9 - 1 / 0.00325

200 x 1.00325^9 - 1 / 13/4000

200 x (4013 / 4000)^9 - 1 / 13/4000

200 x 4013^9 / 4000^9 - 1 / 13/4000

200 x 4013^9 - 4000^9 / 4000^9 / 13/4000

200 x 4013^9 - 4000^9 / 13 - 4000^8

4013^9 - 4000^9 / 13 x 20 x 4000^8

The inequality that represents all the solutions of -2(3x + 6) ≥ 4(x + 7) is x ≤ -4

From the question, we have the following parameters that can be used in our computation:

-2(3x + 6) ≥ 4(x + 7)

Divide both sides of the inequality by -2

So, we have the following representation

3x + 6 ≤ -2(x + 7)

Open the brackets

This gives

3x + 6 ≤ -2x - 14

Add 2x to both sides of the inequality

So, we have the following representations

5x + 6 ≤ -14

Subtract 6 from both sides of the inequality

So, we have the following representations

5x ≤ -20

Divide both side of the inequality

x ≤ -4

Hence, the solution is x ≤ -4

A control group on the dependent variable, P-value is higher than the usual cutoff of 0.05 for rejecting the null hypothesis that there is no difference between the groups, this is frequently regarded as evidence that the difference between the groups is not statistically significant.

In an analysis testing difference between an experimental and a control group on the dependent variable, a p-value of 0.07 means that there is a 7% chance of obtaining a difference as large or larger than the observed difference between the two groups, assuming that there is no true difference between the groups in the population.

Interpreted as evidence that the difference between the groups is not statistically significant, since the p-value is greater than the conventional threshold of 0.05 for rejecting the null hypothesis of no difference between the groups.

Statistical significance does not necessarily imply practical significance, and there may still be a meaningful difference between the groups that is not detected by the statistical test.

Additionally, the interpretation of a p-value depends on the study design, sample size, and other factors, and should be considered in conjunction with other information about the study.

True difference between the groups in the population, a p-value of 0.07 indicates that there is a 7% chance of finding a difference as large or larger than the observed difference between the two groups in an analysis testing the difference between an experimental and a control group on the dependent variable.

P-value is higher than the usual cutoff of 0.05 for rejecting the null hypothesis that there is no difference between the groups, this is frequently regarded as evidence that the difference between the groups is not statistically significant.

It's crucial to remember that statistical significance does not always imply practical relevance.

There could still be a significant difference between the groups that is not shown by statistical analysis.

Question 1a

To calculate the book value at the end of the first year using straight-line depreciation, we need to determine the annual depreciation expense first. The straight-line method assumes that the asset depreciates by an equal amount each year over its useful life. Therefore, we can use the following formula to calculate the annual depreciation:

Annual Depreciation = (Cost - Salvage Value) / Useful Life

Substituting the given values, we get:

Annual Depreciation = ($200,000 - $20,000) / 10 years = $18,000 per year

This means that the tractor will depreciate by $18,000 each year for the next 10 years.

To determine the book value at the end of the first year, we need to subtract the depreciation expense for the year from the original cost of the tractor. Since one year has passed, the depreciation expense for the first year will be:

Depreciation Expense for Year 1 = $18,000

Therefore, the book value of the tractor at the end of the first year will be:

Book Value = Cost - Depreciation Expense for Year 1

= $200,000 - $18,000

= $182,000

So the book value of the tractor at the end of the first year, December 31, 2022, using straight-line depreciation is $182,000. so the answer is D

Question 1(b)

To determine the farmer's noncurrent liabilities, we need to use the information provided to calculate the total liabilities and then subtract the current liabilities from it. Here's the step-by-step solution:

Calculate the total current liabilities using the current ratio:

Current Ratio = Current Assets / Current Liabilities

2 = $80,000 / Current Liabilities

Current Liabilities = $80,000 / 2

Current Liabilities = $40,000

Calculate the total liabilities using the debt/equity ratio:

Debt/Equity Ratio = Total Liabilities / Owner Equity

1.0 = Total Liabilities / $100,000

Total Liabilities = $100,000 * 1.0

Total Liabilities = $100,000

Subtract the current liabilities from the total liabilities to get the noncurrent liabilities:

Noncurrent Liabilities = Total Liabilities - Current Liabilities

Noncurrent Liabilities = $100,000 - $40,000

Noncurrent Liabilities = $60,000

Therefore, the farmer's noncurrent liabilities are $60,000. so the answer is B.

The solution to the inequality  |x+4| - 6 < 9 is -19 < x < 11.

The inequality can be solved as follows;

|x+4| - 6 < 9

add 6 to both sides of the inequality

|x+4| - 6 < 9

|x+4| - 6 + 6< 9 + 6

|x+4| < 15

applying absolute rule,

- 15 < x + 4 < 15

Therefore,

x + 4 > -15 and x + 4 < 15

x > -15 - 4  and x < 15 - 4

x > - 19 and x < 11

Therefore, the final inequality is -19 < x < 11

'The best-predicted value of y^ is  97.24 " . We are given the regression equation as y^ = 14.68 + 0.86x, where x is the IQ score of the wife and y^ is the predicted IQ score of the husband.

Substituting x = 96 in the regression equation, we get:

y^ = 14.68 + 0.86(96)

= 14.68 + 82.56

= 97.24

Therefore, the predicted IQ score of the husband when the wife's IQ score is 96 is 97.24.

To check if this prediction is statistically significant at a significance level of 0.05, we can perform a hypothesis test.

Null Hypothesis: β1 = 0 (there is no linear relationship between the IQ scores of husbands and wives)

Alternative Hypothesis: β1 ≠ 0 (there is a linear relationship between the IQ scores of husbands and wives)

We are given the correlation coefficient r = 0.839 and the sample size n = 20. Using these values, we can calculate the t-statistic as:

t = r√(n-2)/√(1-r²) = 0.839√(20-2)/√(1-0.839²) = 5.44

The degrees of freedom for the t-distribution are df = n-2 = 18. Using a t-table with 18 degrees of freedom and a significance level of 0.05, we find that the critical values are ±2.101.

Since the calculated t-statistic of 5.44 is greater than the critical value of 2.101, we reject the null hypothesis and conclude that there is a significant linear relationship between the IQ scores of husbands and wives.

Therefore, we can have confidence in the predicted IQ score of the husband when the wife's IQ score is 96, and we can say that it is statistically significant at a significance level of 0.05.

The requried Burger Quick is able to estimate its wait time more consistently because it has a smaller IQR. Option A is correct.

A straightforward method of expressing statistical data on a plot in which a rectangle is drawn to represent the second and third quartiles, with a vertical line inside to indicate the median value.

Here,
Burger Quick is able to estimate its wait time more consistently because it has a smaller interquartile range (IQR). The IQR is a measure of the spread of the middle 50% of the data and is calculated as the difference between the third quartile (Q3) and the first quartile (Q1). The smaller the IQR, the more consistent the data is around the median, which is represented by the line within the box in the box plot.

In this case, Burger Quick has a smaller IQR (8.0) compared to Super Fast Food (7.0), indicating that the wait times at Burger Quick are more consistent around the median. The range, which is the difference between the maximum and minimum values, is not a good measure of consistency as it is affected by outliers.

Therefore, based on the given information, Burger Quick is able to estimate its wait time more consistently because it has a smaller IQR.

Step-by-step explanation:

Multiply them then divide them by 2

When one zero of the polynomial p(x) = x^2 + 3x + k is 2, the value of k is -10.

If one zero of the polynomial p(x) = x^2 + 3x + k is 2, it means that when we substitute x = 2 into the polynomial, the result is zero.

Let's substitute x = 2 into the polynomial p(x) and set it equal to zero:

0 = (2)^2 + 3(2) + k

0 = 4 + 6 + k

0 = 10 + k

To solve for k, we subtract 10 from both sides of the equation:

k = -10

Therefore, when one zero of the polynomial p(x) = x^2 + 3x + k is 2, the value of k is -10.

The equation is: G = -⁵/₄t + 15

The slope of the function represents that ⁵/₄ gallons of gas is consumed to drive the car for one hour.

The formula for the equation of a line in slope intercept form is:

y = mx + c

where:

m is slope

c is y-intercept

From the graph, we see that:

y-intercept = 15 gallons

Now, the slope is gotten from the formula:

Slope = (y₂ - y₁)/(x₂ - x₁)

Slope = (10 - 5)/(4 - 8)

Slope = -⁵/₄

Thus, equation is:

G = -⁵/₄t + 15
