The two theoretical quantities of ANOVA (Analysis of Variance) are:
1. Between-group variance.

2. Within-group variance:

1. Between-group variance.

This is the variance that can be attributed to differences between the group means.

It is calculated by comparing the mean of each group to the overall mean of all the data points.

The larger the between-group variance, the more likely there are significant differences between the groups.
2. Within-group variance:

This is the variance that can be attributed to differences within each group, i.e., the individual differences among the data points in each group.

It is calculated by comparing the individual data points in each group to their respective group mean.

The smaller the within-group variance, the more likely the groups are homogeneous.
In ANOVA, these two quantities are compared using an F-ratio.

If the between-group variance is significantly larger than the within-group variance, it indicates that there are significant differences between the group means, and the null hypothesis can be rejected.

There are 56 possible permutations of 8 items taken 2 at a time. To express the number of permutations of 8 items taken 2 at a time, we use the notation P(8,2) or sometimes written as 8P2.

Permutations are arrangements of items in a specific order where the order matters.
To calculate the number of permutations, we use the formula:
P(n, r) = n! / (n - r)!
In our case, n is the total number of items (8) and r is the number of items taken at a time (2). Using the formula:
P(8, 2) = 8! / (8 - 2)!
= 8! / 6!
Now, let's calculate the factorials:
8! = 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1
6! = 6 × 5 × 4 × 3 × 2 × 1

Divide 8! by 6!:
P(8, 2) = (8 × 7 × 6 × 5 × 4 × 3 × 2 × 1) / (6 × 5 × 4 × 3 × 2 × 1)
Notice that the 6!, which is (6 × 5 × 4 × 3 × 2 × 1), cancels out from both the numerator and the denominator, leaving us with:
P(8, 2) = 8 × 7
P(8, 2) = 56
So, there are 56 possible permutations of 8 items.

The  probability that in a random sample of 45 people who took the remedy, 40 of them had a reduction of symptoms within a day is approximately 0.674, rounded to three decimal places.

This problem can be solved using the binomial distribution.

Let X be the number of people out of 45 who have a reduction of symptoms within a day. Then X follows a binomial distribution with n = 45 and p = 0.88.

The probability of exactly 40 people having a reduction of symptoms is given by:

P(X = 40) = (45 choose 40) * (0.88)^40 * (1-0.88)^(45-40)

We can use a calculator or software to evaluate this expression. Alternatively, we can use the normal approximation to the binomial distribution, since n is large and p is not too close to 0 or 1.

Using the normal approximation, we can approximate X as a normal distribution with mean mu = n*p = 39.6 and standard deviation sigma = sqrt(n*p*(1-p)) = 1.964.

Then the probability of X being less than or equal to 40 can be approximated by the cumulative distribution function of the standard normal distribution:

P(X <= 40) = P((X - mu)/sigma <= (40.5 - 39.6)/1.964) = P(Z <= 0.458)

Using a standard normal table or software, we can find that P(Z <= 0.458) is approximately 0.6736.

Therefore, the probability that in a random sample of 45 people who took the remedy, 40 of them had a reduction of symptoms within a day is approximately 0.674, rounded to three decimal places.

Answer:

270 minutes or 4.5 hours

Step-by-step explanation:

You need to find the unit rate in order to solve this problem with the given information. In order to find the unit rate (in minutes) let's find each minute. Do 3600/180=20. You use 180 because that's the amount of minutes in 3 hours. Then, you take 5400 and divide it by 20 to get 270. Convert back to hours and rounded you get 4.5 hours.

a) The probability that all 3 of your answers are incorrect is 27/64.

b) The probability that all 3 of your answers are correct is 1/64.

c) The probability that exactly 1 of your answers are correct is 9/16.

(a) The probability of guessing the incorrect answer for a single question is 3/4. Since each question is independent of the others, the probability of guessing all 3 questions incorrectly is:

(3/4) x (3/4) x (3/4) = 27/64

(b) Similarly, the probability of guessing all 3 questions correctly is:

(1/4) x (1/4) x (1/4) = 1/64

(c) To calculate the probability that exactly 1 of your answers are correct, we need to consider all possible ways in which this could happen. There are three questions and each question has four possible answers, so there are a total of 4 x 4 x 4 = 64 possible ways to answer all three questions.

The number of ways to answer exactly one question correctly is:

3 x (1/4) x (3/4) x (3/4) = 27/64

(We are multiplying by 3 because there are three ways to choose which question to answer correctly.)

Similarly, the number of ways to answer exactly two questions correctly is:

3 x (1/4) x (1/4) x (3/4) = 9/64

(The factor of 3 comes from the three ways to choose which questions to answer correctly.)

Finally, the number of ways to answer all three questions incorrectly is:

(3/4) x (3/4) x (3/4) = 27/64

So the probability of answering exactly one question correctly is:

27/64 + 9/64 = 36/64 = 9/16

If you meet all the criteria for an independent t-test but do not satisfy the assumption of normality, you should technically do a non-parametric test instead of an independent t-test.

So, the correct answer is D.

Non-parametric tests do not require the data to be normally distributed, unlike parametric tests such as t-tests. Non-parametric tests include the Mann-Whitney U test, Wilcoxon rank-sum test, and Kruskal-Wallis test.

These tests are based on ranks rather than the actual values of the data and are generally less powerful than parametric tests, meaning that they may require larger sample sizes to achieve the same level of statistical significance.

It is important to choose the appropriate statistical test for your data to ensure accurate results and conclusions. Simply redoing the experiment or ignoring the violation of the normality assumption is not a valid solution.

Answer: To find Jordan's balance after he makes the minimum payment for May, we need to calculate his balance at the end of each month, taking into account his purchases, the interest charged, and the minimum payment made.

In March, Jordan's balance was $628.16 and he made a minimum payment of:

$628.16 x 3.96% = $24.92

His purchases in March totaled $50.81, so his balance after March was:

$628.16 + $50.81 = $678.97

The interest charged in March would be:

$678.97 x (10.59%/12) = $5.72

So his balance after interest was added in March would be:

$678.97 + $5.72 = $684.69

In April, Jordan's balance was $684.69 and he made a minimum payment of:

$684.69 x 3.96% = $27.13

His purchases in April totaled $77.36 + $32.40 + $49.20 = $159.96, so his balance after April was:

$684.69 + $159.96 = $844.65

The interest charged in April would be:

$844.65 x (10.59%/12) = $7.10

So his balance after interest was added in April would be:

$844.65 + $7.10 = $851.75

In May, Jordan's balance was $851.75 and he made a minimum payment of:

$851.75 x 3.96% = $33.77

His purchases in May totaled $25.79 + $79.39 + $79.08 = $184.26, so his balance after May would be:

$851.75 + $184.26 = $1,036.01

The interest charged in May would be:

$1,036.01 x (10.59%/12) = $8.71

So his balance after interest was added in May would be:

$1,036.01 + $8.71 = $1,044.72

Therefore, Jordan's balance after he makes the minimum payment for May would be $1,044.72, which is closest to answer (a) $1,094.10.

To calculate Juan's tax liability, we need to first determine his taxable income. We can do this by subtracting his exemptions and deductions from his total income:

Total income: $98,066 + $2,454 = $100,520

Exemption amount: $4,000

Standard deduction for Head of Household: $9,350 (for 2017)

Itemized deductions: $5,864 + $6,487 + $6,846 + $8,147 = $27,344

Total deductions: $9,350 + $27,344 = $36,694

Taxable income: $100,520 - $4,000 - $36,694 = $59,826

Using the tax tables for 2017, we can calculate Juan's tax liability:

Taxable income: $59,826

Tax liability: $10,517.50

Juan's W-2 shows that $11,799 was withheld for federal taxes, which is more than his calculated tax liability of $10,517.50. Therefore, Juan will receive a refund.

Refund amount: $11,799 - $10,517.50 = $1,281.50

Therefore, Juan will receive a refund of $1,281.50.

Answer:

Using the information provided, we can calculate Juan's taxable income and then use the tax table to determine his federal income tax liability. Here are the calculations:

Juan's total income:

W-2 income: $98,066

Interest and dividends: $2,454

Total: $100,520

Juan's adjustments:

Exemption amount: $4,000

Adjusted Gross Income (AGI):

Total income - Exemption amount

$100,520 - $4,000 = $96,520

Juan's deductions:

State and local taxes: $5,864

Property tax: $6,487

Mortgage interest: $6,846

Charitable contributions: $8,147

Total deductions: $27,344

Juan's taxable income:

AGI - Deductions

$96,520 - $27,344 = $69,176

Using the tax table for Head of Household filers, Juan's federal income tax liability is approximately $12,998.

Juan's federal tax withheld from his W-2 is $11,799. Since this amount is less than his tax liability of $12,998, he will owe additional taxes of approximately $1,199.

Therefore, Juan will owe an additional $1,199 in federal income taxes when he files his tax return.

Each floor takes two seconds, the total time for your daily elevator ride is 52 seconds.

The elevator ride takes 4672 seconds or approximately 77.87 minutes.

To calculate the time of the elevator ride, we need to find the total number of levels the elevator travels through from the basement parking lot to the 23rd floor. The elevator travels a total of 23 + 3 = 26 levels.

Since the elevator takes 2 seconds per level, we can multiply 26 by 2 to get the total time the elevator ride takes.

26 x 2 = 52 seconds.

Therefore, the elevator ride from the basement parking lot to the 23rd floor takes 52 seconds. However, we need to remember that the elevator ride is a round trip. This means that the elevator will travel from the 23rd floor back down to the basement parking lot. The total time of the elevator ride is therefore 2 x 52 = 104 seconds.

To convert this time into minutes, we can divide 104 by 60.

104 / 60 = 1.73333...

This means that the elevator ride takes approximately 1.73 minutes. To be more precise, we can multiply 0.73 by 60 to get the seconds:

0.73 x 60 = 43.8

So, the elevator ride takes 1 minute and 43.8 seconds, or approximately 77.87 minutes.

Answer:

Plot the points on the graphing calculator, and then generate a linear regression equation.

y = -.457013x + 7.80995

r^2 = .4963, r = -.7045

x = 4--->y = 5.98

x = 6--->y = 5.07

A regression line passing through (4, 6) and (6, 5) would best fit this data.

Check the picture below.

To find the standard deviation of the data set, you can use the formula:

σ = √[Σ(x - μ)² / N]

Where:

- σ is the standard deviation

- Σ is the sum of

- x is each value in the data set

- μ is the mean of the data set

- N is the number of values in the data set

First, find the mean of the data set:

μ = (2 + 4 + 4 + 5 + 7 + 8 + 8 + 9 + 12 + 15 + 17 + 28) / 12 = 9.5

Next, calculate the sum of the squared differences between each value and the mean:

Σ(x - μ)² = (2 - 9.5)² + (4 - 9.5)² + (4 - 9.5)² + (5 - 9.5)² + (7 - 9.5)² + (8 - 9.5)² + (8 - 9.5)² + (9 - 9.5)² + (12 - 9.5)² + (15 - 9.5)² + (17 - 9.5)² + (28 - 9.5)² = 1018

Then, divide the sum by the number of values in the data set:

1018 / 12 = 84.83

Finally, take the square root of the result to find the standard deviation:

σ = √84.83 = 9.2

Therefore, the standard deviation of the data set is 9.2 (rounded to one decimal place).

The new dimensions of the pictures are 2.5 inches by 3.5 inches.

Chris did image resizing of Career Week, which originally measured 5 inches by 7 inches, by a factor of 1/2. This means that he reduced each dimension of the pictures by half of its original size.

To calculate the new dimensions, he multiplied each original dimension by the scaling factor of 1/2.  

If the pictures were resized by a factor of 1/2, it means that each dimension was reduced to half of its original size.

The original dimensions of the pictures were 5 inches by 7 inches.

Resizing each dimension by a factor of 1/2 gives:

5 inches x 1/2 = 2.5 inches

7 inches x 1/2 = 3.5 inches

Therefore, the new dimensions of the pictures are 2.5 inches by 3.5 inches.

This means that the new pictures are significantly smaller than the original ones, which may affect their resolution and quality.

However, depending on the intended use of the pictures, a smaller size may be suitable or even desirable.

The function `findPairs(nums, k)` takes an array of integers `nums` and an integer `k` as input and returns the number of unique `k`-diff pairs in the array. It first creates a dictionary to store the frequency of each integer in the array and then iterates through the keys in the dictionary to count the unique pairs.

To solve this problem, we can follow the below steps:

1. Create a dictionary to store the frequency of each integer  in the array.
2. Iterate through the keys in the dictionary and check if the key + k is also in the dictionary. If it is, increment the count of unique pairs.
3. If k = 0, then we need to count the number of keys in the dictionary that have a frequency greater than or equal to 2.
4. Return the count of unique pairs.

Here's the Python code that implements the above steps:

```
def findPairs(nums, k):
   if k < 0:
       return 0
   
   freq = {}
   for num in nums:
       freq[num] = freq.get(num, 0) + 1
   
   count = 0
   for key in freq.keys():
       if k == 0:
           if freq[key] >= 2:

       else:
           if key + k in freq:
               count += 1
               
   return count

An illustration showing a pentagon lying on ray AB, which when extended forms an exterior angle and is marked as 2x plus 14 degrees, the correct statements are (2x + 14)° + (7x + 13)° = 180°, (7x + 13)° = 132°, x = 7°.

In the given illustration, we have a pentagon with base AB lying on a line or ray AB. Let's call the first interior angle to the right of the exterior angle marked as 2x + 14 degrees as angle C.

We can see that the sum of the measures of all interior angles of a pentagon is 180 degrees. Hence, the sum of all interior angles of this pentagon is:

C + angle D + angle E + angle F + angle G = (5 - 2) x 180 degrees (since a pentagon has five sides and angles)

(2x + 14)° + (7x + 13)° = 180° (sum of interior angles of a pentagon)

(7x + 13)° = 132° (simplifying the above equation)

x = 7° (solve for x by subtracting 14 from both sides of the first equation)

Then here is S5 though S8

And finally we arrive at S9.

[tex]S_{n} = S_{n-1} - 2\\\\S_{9} = S_{9-1} - 2\\\\S_{9} = S_{8} - 2\\\\S_{9} = 4 - 2\\\\S_{9} = 2\\\\[/tex]

Because we have an arithmetic sequence, there is a shortcut.

[tex]a_n[/tex] represents the nth term

S9 refers to the 10th term because we started at index 0. So we plug n = 10 into the arithmetic sequence formula below.

[tex]a_n = a_1 + d(n-1)\\\\a_n = 20 + (-2)(n-1)\\\\a_n = 20 - 2(n-1)\\\\a_{10} = 20 - 2(10-1)\\\\a_{10} = 20 - 2(9)\\\\a_{10} = 20 - 18\\\\a_{10} = 2\\\\[/tex]

In other words, we start with 20 and subtract off 9 copies of 2 to arrive at 20-2*9 = 20-18 = 2, which helps see a faster way why [tex]S_9 = 2[/tex]

568861.07 square units is the area outside the triangle.

First, let's find the area of the triangle ABC using Heron's formula:

s = (AB + BC + AC)/2 = (320 + 440 + 250)/2 = 505

Area of triangle ABC = √(s(s-AB)(s-BC)(s-AC))

= √(505(505-320)(505-440)(505-250))

= √(50518565*255)

= 39351.23 square units

Next, let's find the radius of the circle inscribed in the triangle. The radius is given by:

r = (Area of triangle ABC) / (Semi-perimeter of triangle ABC)

= (25450) / (505/2)

= 100

Now, we can find the area of the circle with a radius of 440:

Area of circle = πr²

= π(440)²

= 608212.3

Finally, we can find the area outside the triangle that will be sprinkled:

The area outside the triangle = Area of the circle - Area of triangle ABC

= 608212.3 - 39351.23

= 568861.07 square units (approx)

Therefore, the area outside the farm that will be sprinkled is approximately 568861.07 square units.
