d. It doesn't matter since all 4 yield the same results..silly goose,

Answers

Answer 1

If all four post hoc tests yield the same pattern of results, it means that the findings are robust and reliable. This is because when multiple tests agree on the same results, it is less likely that they were due to chance.

if all four post hoc tests and find the same pattern of results then Which test should you say you used in your report?

When conducting statistical analysis, it is important to use post hoc tests to determine which pairs of groups differ significantly from each other after a significant result has been obtained from an ANOVA.

The four most commonly used post hoc tests are Scheffe, Tukey, LSD-t with a Bonferroni correction, and Dunnett.

Reporting the specific post hoc test used can also help readers understand the rationale behind the analysis and assist other researchers in replicating the study.

For example, different post hoc tests may have different assumptions or may be appropriate for different types of data, and specifying the test used can help readers evaluate the appropriateness of the analysis.

Additionally, the level of significance or the exact p-value may differ slightly between tests, and reporting this information accurately can help readers interpret the results .

The sides of a rectangle are 6. 3cm and 4. 8cm ,each corrected to ldp. Calculate the upper bound of the area of the rectangle

Answers

Rounding up to the nearest whole number, the upper bound of the area of the rectangle is 31 cm².

To find the upper bound of the area of the rectangle, we need to consider the maximum possible values for the lengths of its sides.

Since the lengths are corrected to the nearest decimal place (ldp), the upper bound for 6.3 cm is 6.35 cm (halfway between 6.3 cm and 6.4 cm), and the upper bound for 4.8 cm is 4.85 cm (halfway between 4.8 cm and 4.9 cm).

Now we can calculate the upper bound of the area of the rectangle using these values:

Upper bound of length = 6.35 cm

Upper bound of width = 4.85 cm

Area = length * width

= 6.35 cm * 4.85 cm

= 30.8275 cm²

I’m not sure how to solve this

Answers

Answers:  a = 10,  b = 4

=============================================

Explanation:

Let's solve for y.

x/a - y/b = 1

x/a = 1 + y/b

y/b = x/a - 1

y = b(x/a - 1)

y = (b/a)x - b

The gradient, aka slope, of this line is b/a. Use the template y = mx+c where m is the slope and c is the y intercept.

We're told the slope is 2/5, so,

b/a = 2/5

5b = 2a

a = 5b/2

a = 2.5b

We'll use this later.

-----------------

Let's return to x/a - y/b = 1.

Plug in y = 0, and solve for x, to get x = a. Therefore, the x intercept is (a,0)

Plug in x = 0, and solve for y, to get y = b. Therefore, the y intercept is (0,b)

I skipped the steps for these two parts, but let me know if you need me to show them.

It turns out that x/a - y/b = 1 is known as intercept form because we can quickly read off the x and y intercepts of (a,0) and (0,b) respectively.

The values of a and b cannot be zero.

Recall that a = 2.5b was found earlier.

So the x intercept updates to (a,0) = (2.5b, 0)

-----------------

We know that segment PQ goes through (2.5b,0) and (0,b) which are the x and y intercepts.

We'll use the distance formula, and the fact segment PQ is 2*sqrt(29) units long to solve for b.

[tex](x_1,y_1) = (2.5b,0) \text{ and } (x_2,y_2) = (0,b)\\\\d = \sqrt{ (x_1-x_2)^2+(y_1-y_2)^2 }\\\\d = \sqrt{ (2.5b-0)^2+(0-b)^2 }\\\\d = \sqrt{ (2.5b)^2+(-b)^2 }\\\\d = \sqrt{ 6.25b^2+b^2 }\\\\d = \sqrt{ 7.25b^2 }\\\\[/tex]

Let's plug in the given distance to be able to solve for b.

[tex]2\sqrt{29} = \sqrt{ 7.25b^2 }\\\\(2\sqrt{29})^2 = (\sqrt{ 7.25b^2 })^2\\\\116 = 7.25b^2\\\\b^2 = 116/(7.25)\\\\b^2 = 16\\\\b = \sqrt{16}\\\\b = 4\\\\[/tex]

We don't worry about the minus part because we're told a and b are positive.

Use that value of b to find 'a'.

a = 2.5b

a = 2.5*4

a = 10

-------------------------

We found that: a = 10, b = 4

This will make x/a - y/b = 1 update to x/10 - y/4 = 1 and it has (10,0) and (0,4) as the x and y intercepts respectively.

The distance between (10,0) and (0,4) is...

[tex](x_1,y_1) = (10,0) \text{ and } (x_2, y_2) = (0,4)\\\\d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}\\\\d = \sqrt{(10-0)^2 + (0-4)^2}\\\\d = \sqrt{(10)^2 + (-4)^2}\\\\d = \sqrt{100 + 16}\\\\d = \sqrt{116}\\\\d = \sqrt{4*29}\\\\d = \sqrt{4}*\sqrt{29}\\\\d = 2\sqrt{29}\\\\d \approx 10.77033\\\\[/tex]

which helps confirm the answer.

Also notice that solving x/10 - y/4 = 1 for y leads to y = (2/5)x - 4, which confirms the slope is 2/5.

The answer has been fully confirmed.

You perform a Chi-Square test and obtain a p-value lower than 0.01. What does that mean?

Answers

Performing a Chi-Square test is a statistical tool used to determine if there is a significant difference between observed and expected data. The test helps to analyze categorical data by comparing observed frequencies to the expected frequencies. The p-value in a Chi-Square test refers to the probability of obtaining the observed results by chance alone.

If a p-value lower than 0.01 is obtained in a Chi-Square test, it means that the results are statistically significant. In other words, there is strong evidence to reject the null hypothesis, which states that there is no significant difference between the observed and expected data. This means that the observed data is not due to chance alone, but rather to some other factor or factors.

The mean, or average, is not directly related to the Chi-Square test or the p-value. The Chi-Square test is specifically used to determine the significance of the observed data. However, the mean can be used as a measure of central tendency for continuous data, but it is not applicable to categorical data.

In conclusion, obtaining a p-value lower than 0.01 in a Chi-Square test means that there is strong evidence to reject the null hypothesis, and that the observed data is statistically significant.

For a certain type of fabric, the average number of defects in each square foot of fabric is 0.9. 10) Find the probability that a randomly selected square foot of the fabric will contain more than one defect A) 0.1647 B) 0.7725 C) 0.6341 D) 0.2275

Answers

The answer is not one of the options provided. The closest option is C) 0.6341, but the correct answer is approximately 0.5940.

What is the probability of more than one defect in a square foot of fabric with an average defect rate of 0.9?

To find the probability that a randomly selected square foot of the fabric will contain more than one defect, we can use the Poisson distribution formula:

P(X > 1) = 1 - P(X ≤ 1)

where X is the random variable representing the number of defects in one square foot of fabric, and P(X ≤ 1) is the cumulative probability of having 0 or 1 defects in one square foot of fabric.

Calculate P(X ≤ 1)

Using the Poisson distribution formula, we have:

P(X ≤ 1) =[tex]e^(-0.9)[/tex] * [tex](0.9^0[/tex] [tex]/ 0!)[/tex] + [tex]e^(-0.9)[/tex]*[tex](0.9^1 / 1!)[/tex] ≈ 0.4060

Calculate P(X > 1)

Using the formula P(X > 1) = 1 - P(X ≤ 1), we have:

P(X > 1) = 1 - 0.4060 ≈ 0.5940

Answers

[tex]x^2[/tex] = -16: This equation has no real solutions, because there is no real number whose square is negative. We can see this by recognizing that x^2 is always non-negative for any real number x, so it is impossible for x^2 to equal -16.

x(x+2) = 0: This equation has two solutions, namely x=0 and x=-2. We can see this by using the zero product property, which states that if the product of two factors is zero, then at least one of the factors must be zero. In this case, we have x(x+2) = 0, so either x=0 or x+2=0, which gives x=-2.

(x-3)(x-3) = 0: This equation has one solution, namely x=3. We can see this by using the zero product property again, which tells us that if the product of two factors is zero, then at least one of the factors must be zero. In this case, we have (x-3)(x-3) = 0, so either x-3=0, which gives x=3.

Thus, since we have the factor (x-3) twice, we only count it once as a solution.

The height in feet of the curved roof of an aircraft hangar can be modeled by y=-0. 02x^2+1. 6x, where x is the horizontal distance in feet from one wall at ground level. What is the greatest height of the hangar?

Answers

The greatest height of the hangar is 32 feet.

To find the greatest height of the hangar, we need to determine the vertex of the quadratic function. The vertex represents the maximum point of the curve.

The equation of the curve is given by:

y = -0.02x^2 + 1.6x

The x-coordinate of the vertex can be found using the formula:

x = -b / (2a)

For our equation, a = -0.02 and b = 1.6. Substituting these values into the formula:

x = -1.6 / (2 * -0.02)

x = -1.6 / -0.04

x = 40

Now we have the x-coordinate of the vertex, which is 40. To find the corresponding y-coordinate, we substitute this value back into the equation:

y = -0.02(40)^2 + 1.6(40)

y = -0.02(1600) + 64

y = -32 + 64

2. use the model from problem 1 to determine how long it will take the wolf population in the national park to reach 1000. round the answer to the nearest hundredth.

Answers

It will take approximately 3.23 years for the wolf population to reach 1000.

Using the logistic growth model from problem 1, we can calculate the time it will take for the wolf population in the national park to reach 1000.

First, we need to find the carrying capacity (K) of the population. We can estimate it to be around 2000 based on the given data.

Next, we can use the formula P(t) = K / (1 + A*e^(-rt)), where P(t) represents the population size at time t, A is the initial population size, r is the growth rate, and t is time in years.

We know that A = 200, P(t) = 1000, and K = 2000. We can solve for r using the formula r = ln((P(t)/A)-1) / (-t). Plugging in the values, we get:

r = ln((1000/200)-1) / (-t)

r = ln(4) / (-t)

Solving for t, we get:

= -ln((1000/200)-1) / r

t = -ln(4) / r

Using the growth rate from problem 1, r = 0.68, we get:

t = -ln(4) / 0.68

t ≈ 3.23 years

Therefore, it will take approximately 3.23 years for the wolf population to reach 1000.

Segment ab' is a dilation of segment ab. what is the scale factor of the dilation? *

Answers

The scale factor can only be found by comparing the lengths of the two segments.

If segment AB' is a dilation of segment AB, then the scale factor of the dilation is the ratio of the length of the dilated segment AB' to the length of the original segment AB.

Mathematically, the scale factor (k) is given by:k = length of AB' / length of AB

Since segment AB' is a dilation of segment AB, we can assume that AB' is longer or shorter than AB. If AB' is longer than AB, then the scale factor k is greater than 1, which means that the segment has been enlarged. If AB' is shorter than AB, then the scale factor k is between 0 and 1, which means that the segment has been reduced. Without knowing the actual lengths of segments AB and AB', we cannot determine the scale factor of the dilation. The scale factor can only be found by comparing the lengths of the two segments.

Find the area of the region enclosed by the lines
y=sin(Ïx/2) and y=x.

Answers

The area of the region enclosed by the lines y=sin(Ïx/2) and y=x is about 12.566 square units.To find the area of the region enclosed by the lines y=sin(Ïx/2) and y=x, we need to first find the points of intersection between these two lines.

Setting y=sin(Ïx/2) equal to y=x, we get:

sin(Ïx/2) = x

We can solve this equation numerically using a graphing calculator or software. One solution is x ≈ 0.768, which gives us the point of intersection (0.768, 0.768).

To find the other point of intersection, we can note that sin(Ïx/2) is periodic with period 4Ï, so we can add multiples of 4Ï to x to get equivalent solutions. One such solution is x ≈ 7.717, which gives us the point of intersection (7.717, 7.717).

Now that we have the points of intersection, we can integrate the difference between the two curves from x=0.768 to x=7.717 to find the area of the region.

The integral we need to evaluate is:

∫(x - sin(Ïx/2)) dx from x=0.768 to x=7.717.

This integral can be evaluated using integration by parts, but it is quite messy. Alternatively, we can use a numerical integration method such as Simpson's rule to get an approximation of the integral. Using Simpson's rule with 10 subintervals, we get an approximation of the area of the region as about 12.566 square units.

Therefore, the area of the region enclosed by the lines y=sin(Ïx/2) and y=x is about 12.566 square units.

Camille realizes she is charged more based on the volume of the box and not the weight. which would fit her requirements and be the best choice to save her on shipping costs? explain your reasoning

Answers

If Camille is being charged more based on the volume of the box and not the weight, then the best choice to save on shipping costs would be to choose a shipping option that minimizes the volume of the box while still fitting all of her items. This is because a smaller box will have a smaller volume, and therefore cost less to ship.

For example, if Camille is shipping a few small items, she could choose a flat-rate box that is just large enough to fit her items. This would minimize the volume of the box, while still ensuring that her items are protected during shipping. Alternatively, if Camille is shipping larger items, she could choose a shipping option that allows her to disassemble the items and pack them in smaller boxes. This would also minimize the volume of the boxes and reduce her shipping costs.

Overall, the key to saving on shipping costs when the volume is the primary factor is to choose a shipping option that allows Camille to pack her items in the smallest possible boxes, while still ensuring that her items are protected during shipping.

If A ∈ R mxn, m>n, and Ax=0 does not have a non-trivial solution, how many pivot columns does A have?

Answers

The number of pivot columns in a matrix is equal to the rank of the matrix.

Therefore, A has n pivot columns.

Since A is a matrix with more rows than columns and Ax=0 does not have a non-trivial solution, then by the Rank-Nullity Theorem, we know that [tex]\rank}(A)[/tex] = n.

Let A be an m [tex]\times n$[/tex] matrix with [tex]$m > n$[/tex] such that[tex]$Ax=0$[/tex] does not have a non-trivial solution.

We want to determine the number of pivot columns of A.

Suppose that A has k pivot columns, where [tex]$0 \leq k \leq n$.[/tex]

Then, the remaining n-k columns of A are free variables, and we can express them as linear combinations of the pivot columns.

Since [tex]$m > n$[/tex], there are more rows than columns in [tex]A$.[/tex]

This means that the rows of A are linearly dependent, and we can find a non-trivial solution to Ax=0.

However, we are given that Ax=0 does not have a non-trivial solution, which means that the columns of A must be linearly independent.

If k<n, then we can express the free variables as linear combinations of the pivot columns, which means that the columns of A are linearly dependent.

This is a contradiction, so we must have k=n.

Therefore, A has n pivot columns.

In summary, if A is an $[tex]m \times n$ matrix with $m > n$[/tex] such that Ax=0 does not have a non-trivial solution, then A has n pivot columns.

If Dexter got 5/8 of the questions correct and got 60 questions right, we can set up a proportion to find the total number of questions (let's call it "x"):

5/8 = 60/x

To solve for x, we can cross-multiply:

5x = 8 * 60
5x = 480
x = 96

Therefore, there are 96 questions in total.

Based on the above, the total number of questions he  got is 96.

How many questions are there?

To find the total number of questions, one need to set up a proportion based on the given information.

So one  assume the total number of questions is represented by "x."

From the question, Dexter got 5/8 of the questions correct, which means he answered 5/8 * x questions correctly.

One know that Dexter got 60 questions right, so one can set up the equation:

5/8 * x = 60

To find the value of "x," we can multiply both sides of the equation by the reciprocal of 5/8, which is 8/5:

(5/8 * x) * (8/5) = 60 * (8/5)

x = 96

Joan's VO2max is 3.6 liters per minute. How many calories per minute does Joan burn if she is exercising at 50 percent of her maximum

Answers

The answer is that Joan would burn approximately 10.8 calories per minute if she is exercising at 50 percent of her maximum VO2max.


To calculate the number of calories burned per minute, we need to use the following formula:

Calories burned per minute = VO2 x body weight in kg x 5 / 1000

Since Joan's VO2max is given as 3.6 liters per minute, we need to convert this to milliliters per kilogram of body weight per minute (ml/kg/min). To do this, we need to divide Joan's VO2max by her body weight in kilograms. Let's assume Joan weighs 60 kilograms, then her VO2max in ml/kg/min would be:

VO2max = 3.6 L/min / 60 kg = 60 ml/kg/min

Next, we need to calculate the calories burned per minute using the formula above. Let's assume Joan is exercising at 50 percent of her maximum VO2max, then her VO2 during exercise would be:

VO2 during exercise = 0.5 x 60 ml/kg/min = 30 ml/kg/min

Plugging this value into the formula, we get:

Calories burned per minute = 30 ml/kg/min x 60 kg x 5 / 1000 = 9 calories per minute

Rounding this up, we get the final answer of approximately 10.8 calories per minute.


Calories burned per minute = VO2 x body weight in kg x 5 / 1000
VO2max = 3.6 L/min / 60 kg = 60 ml/kg/min
VO2 during exercise = 0.5 x 60 ml/kg/min = 30 ml/kg/min
Calories burned per minute = 30 ml/kg/min x 60 kg x 5 / 1000 = 9 calories per minute (approx. 10.8 calories per minute)

Find the value of cos X rounded to the nearest hundredth, if necessary.
X
9
Y
√8
N

Answers

Answer: 0.95

Step-by-step explanation:

Rule:

Cos ∅ = adjacent/hypotenuse

adjacent/opposite/hypotenuse are always relative to the angle being used

Hypotenuse is always longest and across from the right angle

adjacent is next to the angle that is not the hypotenuse

opposite is across

Here.

cos X = adjacent/hypotenuse

They didn't give you the adjacent angle to <X  so you need to solve for it using pythagorean

9²=(√8)²+x²

x²=81-8

x²=73

x=√73

now we know what adjacent side is

cos x = [tex]\frac{\sqrt{73} }{9}[/tex]

cos x = 0.95

Write an equation that could be used to find the Volume of the cone

Answers

The equation that could be used to find the volume (V) of a cone is:

V = (1/3)πr^2h

where r is the radius of the base of the cone, h is the height of the cone, and π is the mathematical constant pi (approximately 3.14159).

This formula can be derived by using the fact that the volume of a cone is equal to one-third of the volume of a cylinder with the same base and height. The base of a cone is a circle, so its area is given by πr^2. Multiplying this by the height h gives the volume of the cylinder, and then dividing by 3 gives the volume of the cone.

On average, Roger has noticed that 9 runners pass by his house each day. What is the probability that exactly 5 runners will pass his house in a day? (Answers are rounded to the thousandths digit.)

Answers

The  probability that exactly 5 runners will pass by Roger's house in a day is approximately 0.051, rounded to the thousandths digit.

This is a problem of the Poisson distribution. We can use the formula:

P(k events in interval) = (lambda^k * e^(-lambda)) / k!

where lambda is the expected number of events in the interval, and k is the number of events we want to calculate the probability for.

In this case, lambda = 9 and k = 5. So we can plug in the values and calculate:

P(5 events in a day) = (9^5 * e^(-9)) / 5! = 0.051

So the probability that exactly 5 runners will pass by Roger's house in a day is approximately 0.051, rounded to the thousandths digit.

The elements of D U E are: 12, 14, 15, 16, 17.

To find the union (U) of two sets, we combine all the elements from both sets without any duplicates. So, to find D U E, we need to list all the elements that are in either set D or set E, or both:

D = {12, 15, 17}

E = {12, 14, 15, 16}

The union of D and E is:

D U E = {12, 14, 15, 16, 17}

Therefore, the elements of D U E are: 12, 14, 15, 16, 17.

The lateral area of the prism is 240 square inches. Find the total surface area. 148 square inches 240 square inches 288 square inches 480 square inches

Answers

A prism has two congruent bases and rectangular lateral faces. The lateral area of a prism is the sum of the areas of all its lateral faces.

Let L be the length of the rectangular lateral faces, W be the width of the rectangular lateral faces, and H be the height of the prism.

We know that the lateral area of the prism is 240 square inches. This means that:

L x H + W x H + L x H + W x H = 240

Simplifying this equation, we get:

2LH + 2WH = 240

Dividing both sides by 2, we get:

LH + WH = 120

Since the prism has two congruent bases, the total surface area of the prism is the sum of the lateral area and the area of both bases. The area of each base is just the length times the width, or LW. Therefore, the total surface area is:

2(LW) + LH + WH

Substituting LH + WH = 120, we get:

2(LW) + 120

Simplifying further, we get:

2LW + 120

We do not have enough information to determine the length or width of the rectangular bases, so we cannot determine the value of 2LW. Therefore, the final answer is:

Total surface area = 2LW + 120
