c) Degree of freedom is 5 .
d) Chi-square test formula:

e) Chi-square statistic value is 13.42
f) Critical value or P value for chi-square is 0.0198 and P value < alpha so, p-Value means here, reject the null hypothesis.
The Race/Ethnicity of U.S. Public Schools for a recent year, the percentages for the Advanced Placement Examine population for that class, and the Overall Student Population sample is taken for study.
a)State the hypotheses : The first step is to state the null hypothesis and an alternative hypothesis.
Null hypothesis: The local results and the U.S AP examinee population are the same.
b) Alternative hypothesis: The local results and the examinee population are not the same. Applying the chi-square goodness of fit test to sample data, we compute the degrees of freedom, the expected frequency counts, and the chi-square test statistic.
c) Degree of freedom, = k - 1 = 6 - 1 = 5
where DF is the degrees of freedom, k is the number of levels of the categorical variable, n is the number of observations in the sample.
d) Using sample data, we will conduct a chi-square goodness of fit test of the null hypothesis. Chi-square test formula:
χ² = (Oᵢ - Eᵢ)²/Eᵢ
Eᵢ is the expected frequency count for level i, Oᵢ is the observed frequency count for level i, and χ² is the chi-square test statistic and excepted value,(Eᵢ)= n× pᵢ
e) The test staistic value, χ² is 13.42..
f) The P-value is the probability that a chi-square statistic having 5 degrees of freedom is more extreme than 13.42.
We use the excel formula,
"=CHISQ.DIST.RT(x,deg_freedom)"
where, x is value which you want to evaluate
=CHISQ.DIST.RT(13.42,5) to find P(χ²> 13.42)
= 0.0198
Result : Since the P-value (0.0198) is less than the significance level (0.05), we have to reject the null hypothesis.

Given the circle below with secants JKL and NML, find the length of JK. Round to the nearest tenth if necessary.
Answers
Using the Intersecting secants theorem, the length of JK in the given diagram is 17
Intersecting secants theorem: Calculating the length of of JKFrom the question, we are to determine the length of JK in the given diagram.
The diagram shows a circle with intersecting secants.
From the Intersecting secants theorem which states that "if two secant segments are drawn to a circle from an exterior point, then the product of the measures of one secant segment and its external secant segment is equal to the product of the measures of the other secant segment and its external secant segment".
Then,
We can write that
JK × KL = NM × ML
From the given diagram,
KL = 14
NM = 14
ML = 17
Substituting the values
JK × 14 = 14 × 17
JK = (14 × 17) / 14
JK = 17
Hence, the length of JK is 17

Answers
The economic value added (EVA) for Home Depot in the fiscal year, 2017, is $6,463.60 million.
What is the economic value added?Economic value added (EVA) measures a company's financial performance or economic profit.
EVA is based on the residual wealth of the company for the fiscal year. It measures the value a company generates from its invested funds at the cost of capital.
EVA is calculated by deducting the cost of capital from the operating profit after tax (NOPAT).
Data and Calculations:2017 total capitalization = $21,904 million
2017 interest paid to debt investors = $877 million
Net income to shareholders = $8,654 million
Corporate tax rate = 21%
Profit before taxes = $10,954 million ($8,654/ 1 - 0.21)
Cost of capital = 10%
= $2,190.4 million ($21,904 x 10%)
EVA = NOPAT - (Invested Capital * WACC)
= $8,654 million - $2,190.4 million
= $6,463.60 million.
Thus, the economic value added (EVA) for Home Depot in the fiscal year, 2017, is $6,463.60 million.

Answer:
x = 16
Step-by-step explanation:
"Solve algebraically" means "solve it using the rules of algebra." You could also solve it by guessing, or by graphing, or by submitting the equation to a machine solver (calculator, app, or web site).
__
To solve for x, undo what has been done to x. The expression on the right shows that x has 2 added, and the sum is divided by 3. We "undo" these operations in reverse order.
undo divide by 3
Multiplication is the inverse operation for division, so we want to multiply both sides of the equation by 3:
3(6) = 3(x +2)/3
18 = x +2
undo add 2
Subtraction is the inverse operation for addition, so we want to subtract 2 from both sides of the equation:
18 -2 = x +2 -2
16 = x
The value of x that makes this equation true is x = 16.

The sum will be close to 1/4
Step-by-step explanation:
1/8+1/6 is 7/24, and 1/4th of that is 6/24, so it is very close.
Answer: The sum will be close to 1/4
Step-by-step explanation:
You can start by making the fractions have the same denominator, (8*6) which gets you 48
You then want to use the butterfly method, so 1/8 becomes 6/48 and 1/6 becomes 8/48. You then add these up to 14/48.
12/48 is 1/4, and 14/48 is close to 12/48, thus making the answer the first option.
If the median is 3.5, we can assume the mean is ____________than 3.5
Answers
We cannot make a general assumption about whether the mean is greater or less than 3.5 based solely on the fact that the median is 3.5.
What is mean?The mean is a measure of central tendency that represents the average value of a set of numbers. It is also called the arithmetic mean or simply the average.
According to question:We cannot make a general assumption about whether the mean is greater or less than 3.5 based solely on the fact that the median is 3.5.
The mean and the median are two different measures of central tendency, and they can have different values depending on the distribution of the data. In general, if a data set is symmetric and bell-shaped, the mean and the median are close to each other. However, if the data set is skewed, the mean and the median may be different.
For example, consider the following two data sets:
Set 1 data: 1, 2, 3, 4, and 5.
The median is 3.
The mean is (1 + 2 + 3 + 4 + 5) / 5 = 15 / 5 = 3.
Data set 2: 1, 2, 3, 4, 10
The median is 3.
The mean is (1 + 2 + 3 + 4 + 10) / 5 = 20 / 5 = 4.
In data set 1, the mean is the same as the median. In data set 2, the mean is greater than the median because the value 10 is an outlier that pulls the mean up.
Therefore, without additional information about the distribution of the data, we cannot make a general assumption about whether the mean is greater or less than 3.5 based solely on the fact that the median is 3.5.

Mean: 8.611, Median: 8, Mode: 8
Let's find the mean, median, and mode for each set of numbers:
Set: 40, 38, 29, 34, 37, 22, 15, 38
Mean: To find the mean, we sum up all the numbers and divide by the total count:
Mean = (40 + 38 + 29 + 34 + 37 + 22 + 15 + 38) / 8 = 273 / 8 = 34.125
Median: To find the median, we arrange the numbers in ascending order and find the middle value:
Arranged set: 15, 22, 29, 34, 37, 38, 38, 40
Median = (29 + 34) / 2 = 63 / 2 = 31.5
Mode: The mode is the number(s) that appear(s) most frequently in the set:
Mode = 38 (appears twice)
Set: 26, 32, 12, 18, 11, 14, 21, 12, 27
Mean: Mean = (26 + 32 + 12 + 18 + 11 + 14 + 21 + 12 + 27) / 9 = 173 / 9 ≈ 19.222
Median: Arranged set: 11, 12, 12, 14, 18, 21, 26, 27, 32
Median = 18
Mode: No mode (all numbers appear only once)
Set: 3, 3, 4, 7, 5, 7, 6, 7, 8, 8, 8, 9, 8, 10, 12, 9, 15, 15
Mean: Mean = (3 + 3 + 4 + 7 + 5 + 7 + 6 + 7 + 8 + 8 + 8 + 9 + 8 + 10 + 12 + 9 + 15 + 15) / 18 ≈ 8.611

Answers
As a result, Plan 4's $38.89 monthly premium is the lowest.
How to find the lowest monthly payments ?The monthly premium you pay for health insurance. You typically have to pay additional fees for your health care in addition to your premium, such as a deductible, copayments, and coinsurance.
(P + Simple Interest) / (500 + 58.33) / 14 = $42.02 is the formula for the monthly payment.
Plan 4: P = $500
t = 18/12 years, and r = 0.12
Simple interest equals $500 * 0.12/* (18/12) = $90.
(P + Simple Interest) / t = ($500 + $90) / 18 = $38.89 is the monthly payment.
Plan 5: P = $500
t = 12/12 years, and r = 0.14.
Simple interest is equal to $500 * 0.14 * (12/12) = $70.
(P + Simple Interest) / t = ($500 + $70) / 12 = $47.50 is the amount due each month.
As a result, Plan 4's $38.89 monthly premium is the lowest.

Answers
The length of the second rectangle is 8 in
How to find the length of the second painting?Since we have painting with an area of 48 in.² and a length of 6 inches, since it is a rectangle, its area is A = LW where
L = length of rectangle = 6 in and W = width of rectangleSo, making Wsubject of the formula, we have
W = A/L
Since
A = 48 in² and L = 6 inSubstituting these into the equation, we have
W = A/L
W = 48 in²/6 in
W = 8 in
Now, since the second painting with an area of 64 in.² it has the same width as the first painting, since it is also a rectangle, its area is A = LW where
L = length of rectangle and W = width of rectangleSo, making L subject of the formula, we have
L = A/W
Since
A = 64 in² and W = 8 inSubstituting these into the equation, we have
L = A/W
L = 64 in²/8 in
L = 8 in
