g A realtor is trying to predict the selling price of houses in Greenville (in thousands of dollars) as a function of Size (measured in thousands of square feet) and whether or not there is a fireplace (FP is 0 if there is no fireplace, 1 if there is a fireplace). Part of the regression output is provided below, based on a sample of 20 homes. Some of the information has been omitted. hh Which statement is supported by the regression output? Select one: At α = .05, FP is not a significant predictor in a two-tailed test FP is a more significant predictor than Size A large house with no fireplace will sell for more than a small house with a fireplace a fireplace adds around $6476 to the selling price of the average house
Answer:
size=13.80966
Step-by-step explanation:
Missing information:
size=13.80966
Since p-value of FP is less than 0.05 so it is significant to the model.
If all other things remain constant then a fire place add approximately $6476 to the selling price of the average house. So statement "A fireplace adds around $6476 to the selling price of the average house." is supported by the model.
It is impossible to definitively determine the correct statement without the actual regression output. While we can make educated guesses about the significance of the 'Fireplace' variable and its impact on the house's selling price, further information like t-values, p-values, and standard errors is required to make a detailed and accurate estimate.
Explanation:With the information provided, it is impossible to definitively determine which of the four options are correct without the actual regression output. However, if it were provided and the p-value for the Fireplace's coefficient is higher than 0.05, we could say at α = .05, FP is not a significant predictor in a two-tailed test. If the regression coefficient for the Fireplace is $6,476 and it is significant, then a fireplace adds around $6476 to the selling price of the average house is correct. However, declaring that FP is a more significant predictor than Size or that a large house with no fireplace will sell for more than a small house with a fireplace, would require further information that goes beyond the coefficients themselves, including the standard errors, t-values, and p-values associated with each coefficient.

If f(x) = 3/x+2 - sqrtx-3 , complete the folowing statement f(19)=____
Answer:-27/7
Step-by-step explanation:
f(x)=3/(x+2) -√(x-3)
f(19)=3/(19+2)-√(19-3)
f(19)=3/21 - √(16)
f(19)=1/7-4/1
f(19)=(1 x 1 - 7 x 4)/7
f(19)=(1-28)/7
f(19)=-27/7
To calculate f(19), we would substitute x with 19 in the function f(x) and simplify. However, the function provided is incomplete or incorrect, and therefore, a solution cannot be confidently provided.
To solve the problem f(19), we have to substitute the value of x with 19 into the provided function f(x). However, based on the question provided, the function seems to be incomplete or incorrectly stated.
If we had a correct form of the function f(x), the process would involve replacing any instance of x with 19 and simplifying the resulting expression according to the rules of arithmetic and algebra.
Example Process with Hypothetical Function
Let's assume the function is given correctly as f(x) = 3/(x+2) - √{x-3}. Then, we would calculate:
Step 1: Substitute x with 19: f(19) = 3/(19+2) - √{19-3}
Step 2: Simplify the expression: f(19) = 3/21 - √{16}
Step 3: Complete the calculations: f(19) = 1/7 - 4
Step 4: Find the common denominator and subtract: f(19) = -27/7
However, since we do not have the correct function, I am unable to confidently provide the solution to f(19).
An insurance company is interested in conducting a study to to estimate the population proportion of teenagers who obtain a driving permit within 1 year of their 16th birthday. A level of confidence of 99% will be used and an error of no more than .04 is desired. There is no knowledge as to what the population proportion will be. The size of sample should be at least _______. 289
Answer:
The size of the sample should be at least 1037.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which
z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].
The margin of error of the interval is given by:
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
99% confidence level
So [tex]\alpha = 0.01[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.01}{2} = 0.995[/tex], so [tex]Z = 2.575[/tex].
A level of confidence of 99% will be used and an error of no more than .04 is desired. There is no knowledge as to what the population proportion will be. The size of sample should be at least
We need a sample size of at least n.
n is found when [tex]M = 0.04[/tex]
We don't know the proportion of the population, so we use [tex]\pi = 0.5[/tex]
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
[tex]0.04 = 2.575\sqrt{\frac{0.5*0.5}{n}}[/tex]
[tex]0.04\sqrt{n} = 2.575*0.5[/tex]
[tex]\sqrt{n} = \frac{2.575*0.5}{0.04}[/tex]
[tex](\sqrt{n})^{2} = (\frac{2.575*0.5}{0.04})^{2}[/tex]
[tex]n = 1036.03[/tex]
Rounding up
The size of the sample should be at least 1037.

What is the slope for y= -1/2x -3
Answer:
-1/2
Step-by-step explanation:
Note the slope intercept form:
y = mx + b
y = (x , y)
m = slope
x = (x , y)
b = y-intercept.
In this case, the number that replaces the m (slope) is -1/2, which is your answer.
~
Answer:
m= -1/2
Step-by-step explanation:
This equation is in slope intercept form:
y=mx+b
where m is the slope and b is the y intercept
We have the equation:
y= -1/2x -3
If we compare the 2 equations:
y=-1/2x -3
y=mx+b
The slope must be -1/2, since x is being multiplied by -1/2
Let the abbreviation PSLT stand for the percent of the gross family income that goes into paying state and local taxes. Suppose one wants to estimate the mean PSLT for the population of all families in New York City with gross incomes in the range $35.000 to $40.000. If sigma equals 2.0, how many such families should be surveyed if one wants to be 90% sure of being able to estimate the true mean PSLT within .5?
Answer:
Number of families that should be surveyed if one wants to be 90% sure of being able to estimate the true mean PSLT within 0.5 is at least 43.
Step-by-step explanation:
We are given that one wants to estimate the mean PSLT for the population of all families in New York City with gross incomes in the range $35.000 to $40.000.
If sigma equals 2.0, we have to find that how many families should be surveyed if one wants to be 90% sure of being able to estimate the true mean PSLT within 0.5.
Here, we will use the concept of Margin of error as the statement "true mean PSLT within 0.5" represents the margin of error we want.
SO, Margin of error formula is given by;
Margin of error = [tex]Z_(_\frac{\alpha}{2}_ ) \times \frac{\sigma}{\sqrt{n} }[/tex]
where, [tex]\alpha[/tex] = significance level = 10%
[tex]\sigma[/tex] = standard deviation = 2.0
n = number of families
Now, in the z table the critical value of x at 5% ( [tex]\frac{0.10}{2} = 0.05[/tex] ) level of significance is 1.645.
SO, Margin of error = [tex]Z_(_\frac{\alpha}{2}_ ) \times \frac{\sigma}{\sqrt{n} }[/tex]
0.5 = [tex]1.645 \times \frac{2}{\sqrt{n} }[/tex]
[tex]\sqrt{n} =\frac{2\times 1.645 }{0.5}[/tex]
[tex]\sqrt{n} =6.58[/tex]
n = [tex]6.58^{2}[/tex]
= 43.3 ≈ 43
Therefore, number of families that should be surveyed if one wants to be 90% sure of being able to estimate the true mean PSLT within 0.5 is at least 43.

which linear function has the steepest slope?
Answer:
Option A is correct.
Step-by-step explanation:
The linear function that has the steepest slope is,
Explanation:
Slope intercept form: The general formula is, where m is the slope and b is the y-intercept.
Option A:
According to slope intercept form:
Slope is -8
Similarly, for
Option B :
Slope is -2
Option C:
Slope is 7
Option D :
Slope is 6
Steepest slope defined as that is closest to being vertical.
This could be a line that is positive or negative slope respectively.
Therefore, the linear function that has the steepest slope is, option A
The steepest slope is in Option 4 with a slope of -4. Therefore, Option 4 has the steepest slope.
To determine which linear function has the steepest slope, we need to compare the slopes of the given options.
The slope of a linear function can be calculated using the formula:
[tex]\[ \text{Slope} = \frac{\text{change in } y}{\text{change in } x} \][/tex]
We will calculate the slopes for each option and compare them.
Option 1:
[tex]\[ \text{Slope} = \frac{-2 - 4}{1 - (-1)} = \frac{-6}{2} = -3 \][/tex]
Option 2:
[tex]\[ \text{Slope} = \frac{13 - 10}{6 - 3} = \frac{3}{3} = 1 \][/tex]
[tex]\[ \text{Slope} = \frac{16 - 10}{9 - 3} = \frac{6}{6} = 1 \][/tex]
[tex]\[ \text{Slope} = \frac{19 - 13}{12 - 9} = \frac{6}{3} = 2 \][/tex]
Option 3:
[tex]\[ \text{Slope} = \frac{-4 - 2}{-1 - 2} = \frac{-6}{-3} = 2 \][/tex]
Option 4:
[tex]\[ \text{Slope} = \frac{-12 - (-4)}{4 - 2} = \frac{-8}{2} = -4 \][/tex]
[tex]\[ \text{Slope} = \frac{-20 - (-12)}{6 - 4} = \frac{-8}{2} = -4 \][/tex]
[tex]\[ \text{Slope} = \frac{-28 - (-20)}{8 - 6} = \frac{-8}{2} = -4 \][/tex]
Comparing the slopes:
- Option 1: Slope = -3
- Option 2: Slopes = 1, 1, 2
- Option 3: Slope = 2
- Option 4: Slopes = -4, -4, -4
The steepest slope is the largest magnitude of slope, regardless of whether it's positive or negative. In this case, the steepest slope is in Option 4 with a slope of -4. Therefore, Option 4 has the steepest slope.

"A sample of 64 hotels in Atlanta was selected in order to determine whether or not the average room price is significantly different from $110. The average price of the rooms in the sample was $112. The population standard deviation is known to be $16. Use a 0.05 level of significance. Use this information to answer Questions 16 to 19. What should be the appropriate null and alternative hypotheses for the purpose of your analysis?"
Answer:
The null and alternative hypothesis are:
[tex]H_0: \mu=110\\\\H_a:\mu\neq 110[/tex]
The null hypothesis failed to be rejected.
There is not enough evidence to support the claim that the average room price in Atlanta is significantly different from $110 (P-value=0.317) .
Step-by-step explanation:
This is a hypothesis test for the population mean.
The claim is that the average room price in Atlanta is significantly different from $110.
Then, the null and alternative hypothesis are:
[tex]H_0: \mu=110\\\\H_a:\mu\neq 110[/tex]
The significance level is 0.05.
The sample has a size n=64.
The sample mean is M=112.
The standard deviation of the population is known and has a value of σ=16.
We can calculate the standard error as:
[tex]\sigma_M=\dfrac{\sigma}{\sqrt{n}}=\dfrac{16}{\sqrt{64}}=2[/tex]
Then, we can calculate the z-statistic as:
[tex]z=\dfrac{M-\mu}{\sigma_M}=\dfrac{112-110}{2}=\dfrac{2}{2}=1[/tex]
This test is a two-tailed test, so the P-value for this test is calculated as:
[tex]P-value=2\cdot P(z>1)=0.317[/tex]
As the P-value (0.317) is bigger than the significance level (0.05), the effect is not significant.
The null hypothesis failed to be rejected.
There is not enough evidence to support the claim that the average room price in Atlanta is significantly different from $110.

What are the critical points of f? b. On what open intervals is f increasing or decreasing? c. At what points, if any, does f assume local maximum and minimum values?
Answer:
Step-by-step explanation:
a) you have that:
[tex]f'(x)=\frac{(x-2)(x+8)}{(x+1)(x-5)},\ \ x\neq -1,5[/tex]
The derivative of a function equals to zero allows you to find the critical points:
[tex]f'(x)=0\\\\(x-2)(x+8)=0\\\\x_1=2\\\\x_2=-8[/tex]
x=2,8 are the critical points
b) To know the behavior if f it is necessary to know where are f is indeterminated. The derivative give to you information about the slope of f. For x=-1,5 you have an infinite slope. Hence, for that values of x you have two indetermination s of f(x.)
However, if you see the atacched images you can obser that the original function (that is obtained with the intgegral) does not have available values for x<5 due to the logrithms. Hence, there are no critical points
The function only increases after x=5 from -infinity to +infinity
c) there are no local maximum neither local minimum

Answer:
Without the picture of diagram, based on your description:
Triangle A is reflected across the x-axis to form triangle B.
Triangle A is rotated to form triangle C.
Option A: Triangle B is a reflection of triangle A across the x-axis.
It is correct because "Triangle A is reflected across the x-axis to form triangle B" => Triangle B is a reflection of triangle A across the x-axis
Option B: Triangle C is not a reflection of triangle A
It is correct because "Triangle A is rotated to form triangle C"
Option C: Triangle B is a reflection of triangle A across the y-axis
It is incorrect, because "Triangle A is reflected across the x-axis to form triangle B" => Triangle B is a reflection of triangle A across the x-axis, not y-axis.
Option D: Triangle C is a reflection of triangle A across the line y = x + 3
It is incorrect, because "Triangle A is rotated to form triangle C" => triangle C is a result of rotation, not reflection.

Andres is offered a job as manager of a health club. The job will pay $3,100 per month, paid semimonthly. Along with the base salary, the company offers to pay half the cost of medical insurance and will match Andres' contribution to a retirement plan up to a total of $3,500. If the full cost of the medical insurance is $450 per month and Andres plans to contribute the full $3,500 every year to a retirement plan, what is the actual annual value of this job to Andres?
Andres' job has an actual annual value of $43,400. This figure was obtained by summing his base salary, the company's health insurance contribution, and the company's retirement plan contribution.
Explanation:To calculate the actual annual value of the job offer to Andres, we need to take into account his base salary, the company's contribution towards medical insurance, and the company's matching contribution to his retirement plan. Andres receives a base salary of $3,100 per month and gets paid semimonthly, which equates to an annual salary of $3,100 x 12 = $37,200.
The company pays half of Andres' $450 monthly medical insurance expense. So, that will be $450/2 = $225 per month, and over a year, that's $225 x 12 = $2,700.
Lastly, the company matches Andres' contribution to his retirement plan up to $3,500 annually.
To get the total value, add all these figures up: $37,200 (base salary) + $2,700 (health insurance contribution) + $3,500 (retirement contribution) = $43,400.
So, the actual annual value of Andres' job is $43,400.

A light bulb consumes 600 watt hours per day. How many Watt hours? Does it consume in 3 days and 12 hours?
Answer:
2100 Watt Hours
Step-by-step explanation:
600 Watt hours is consumed by the bulb every day.
3 Days and 12 Hours = 3 1/2 Days
To find how many Watt hours was consumed in 3 1/2 days we must multiply both of the numbers.
600 x 3 1/2 = 2100
Therefore, we can conclude that 2100 Watt Hours are consumed in 3 Days and 12 Hours.
A recipe calls for 3 teaspoons of orange juice. A can of orange juice is 20 fluid ounces. How many teaspoons of juice are in the can? My child needs help and I don't get it. Help!
Answer:
Step-by-step explanation:
You have to look up (google) the number of ml in a fluid ounce. It equals 29.57 ml approximately.
Next you must look up the number of mL in a teaspoon. The conversion factor turns out to be 4.93 mL = 1 teaspoon.
1 fluid ounce = 29.57 mL
20 fluid ounces = x mL
1/20 = 29.57 /x
x = 20*29.57
x = 591.4 mL
1 teaspoon = 4.93 mL
x teaspoons = 591.4
4.93 * x = 591.4
4.93 * x/4.93 = 591.4 / 4.93
x = 119.96
