Verify that the sample standard deviations use of ANO\A allow the the means to compare the population means. What do the suggest about the effect of the subject’s gender and attractiveness of the confederate on the evaluation of the product?

Answers

On performing an ANOVA test the p-value obtained is less than the chosen significance level, hence it is verified that the sample standard deviations use of ANOVA allow the the means to compare the population means. Since ANOVA test shows significant difference therefore, it suggests that these factors play a role in influencing the evaluation of the product.

To verify that the sample standard deviations use of ANOVA allows means to compare the population means, discuss the terms ANOVA, sample standard deviation, population means.

1. ANOVA (Analysis of Variance): ANOVA is a statistical method used to compare the means of multiple groups to determine if there's a significant difference between them.

2. Sample Standard Deviation: Sample standard deviation is a measure of how spread out the values in a sample are. It helps estimate the population standard deviation, which is necessary for calculating the F statistic in ANOVA.

a. Calculate the sample means and standard deviations for each group.
b. Perform an ANOVA test using calculated means and standard deviations.
c. Interpret results: If p-value obtained from the ANOVA test is less than the chosen significance level (e.g., 0.05), it means there is a significant difference between population means.

Regarding the effect of the subject's gender and attractiveness of the confederate on the evaluation of the product, if the ANOVA test shows a significant difference, it suggests that these factors play a role in influencing the evaluation of product. You can further analyze the data by performing post-hoc tests to identify which specific groups differ significantly.

Adding fractions​

Need help​

Answers

Answer:

1) 1/2 + 1/4 = 2/4 + 1/4 = 3/4

2) To add these fractions, you need to find a common denominator. The smallest common multiple of 7 and 9 is 63, so we can write:

3/7 * 9/9 + 2/9 * 7/7 = 27/63 + 14/63 = 41/63

3) To add these fractions, you need to find a common denominator. The smallest common multiple of 5 and 15 is 15, so we can write:

3/5 * 3/3 + 1/15 * 1/1 = 9/15 + 1/15 = 10/15

But we can simplify this fraction by dividing both the numerator and denominator by 5:

10/15 = 2/3

4) To add these fractions, you need to find a common denominator. The smallest common multiple of 9 and 8 is 72, so we can write:

1/9 * 8/8 + 7/8 * 9/9 = 8/72 + 63/72 = 71/72

5) To add these fractions, you need to find a common denominator. The smallest common multiple of 7 and 21 is 21, so we can write:

6/7 * 3/3 + 2/21 * 1/1 = 18/21 + 2/21 = 20/21

6) To add these fractions, we need to find a common denominator first. The smallest number that both 6 and 10 divide into is 30. So, we convert 4/6 to 20/30 by multiplying both the numerator and denominator by 5, and we convert 2/10 to 3/15 by multiplying both the numerator and denominator by 3. Now we have:

20/30 + 3/15 = (20x1 + 3x2)/(30x2) = 23/60

Therefore, 4/6 + 2/10 = 23/60.

7) To add these fractions, we need to find a common denominator first. The smallest number that both 11 and 22 divide into is 22. So, we convert 1/11 to 2/22 by multiplying both the numerator and denominator by 2, and we convert 3/22 to 3/22 (it is already in terms of 22). Now we have:

2/22 + 3/22 = (2 + 3)/22 = 5/22

Therefore, 1/11 + 3/22 = 5/22.

8) To add these fractions, we need to find a common denominator first. The smallest number that both 4 and 20 divide into is 20. So, we convert 1/4 to 5/20 by multiplying both the numerator and denominator by 5, and we convert 8/20 to 8/20 (it is already in terms of 20). Now we have:

5/20 + 8/20 = (5 + 8)/20 = 13/20

Therefore, 1/4 + 8/20 = 13/20.

9) To add these fractions, we need to find a common denominator first. The smallest number that both 7 and 9 divide into is 63. So, we convert 4/7 to 24/63 by multiplying both the numerator and denominator by 3, and we convert 2/9 to 14/63 by multiplying both the numerator and denominator by 7. Now we have:

24/63 + 14/63 = (24 + 14)/63 = 38/63

Therefore, 4/7 + 2/9 = 38/63.

10) To add these fractions, we need to find a common denominator first. The smallest number that both 10 and 30 divide into is 30. So, we convert 6/7 to 18/30 by multiplying both the numerator and denominator by 3, and we convert 2/30 to 1/15 by multiplying both the numerator and denominator by 15. Now we have:

18/30 + 1/15 = (18x1 + 1x2)/(30x2) = 37/30

Therefore, 6/7 + 2/21 = 37/30.

The sides of the base of a right square pyramid are 3 meters in length, and its slant height is 6 meters. if the lengths of the sides of the base and the slant height are each multiplied by 3, by what factor is the surface area multiplied?

a. 12

b. 3^3

c. 3^2

d. 3

Answers

If the base and slant height both are divided by a factor of 3, the surface area will get multiplied by factor, option b, 3².

Here we are given that the square pyramid has a base of 3m and a slant height of 6 m.

The surface area formula for a square pyramid with square edge a and slant height h is

a² + 2a√(a²/4  + h²)

Here, a = 3 and h = 6. Hence we get

3² + 2X3√(3²/4  + 6²)

= 46.108

Now the base and slant height are multiplied by 3. Hence we will get

9a² + 6a√(9a²/4  + 9h²)

414.972

Now, dividing both obtained we will get

414.972/46.108

= 9

= 3²

Hence, it should be multiplied by 3².

Mario is buying a number of hamburgers from the local store that cost \$2. 90$2. 90 each. He is also buying one packet of hamburger rolls at a cost of \$4. 75$4. 75. He has \$39. 55$39. 55 to spend at the store. Write and solve an inequality that shows how many hamburgers, hh, Mario can afford to buy. Write the inequality

Answers

Mario can afford to buy a maximum of 12 hamburgers from the local store.

How to find the number of hamburgers Mario can afford to buy given certain prices and a budget?

Let's assume Mario can buy "h" hamburgers.

The cost of each hamburger is $2.90, and Mario wants to buy "h" hamburgers, so the total cost of hamburgers would be 2.90h.

He is also buying one packet of hamburger rolls, which costs $4.75.

Therefore, the total amount he can spend at the store must be less than or equal to his budget of $39.55.

Putting it all together, the inequality representing this situation is:

2.90h + 4.75 ≤ 39.55

To find out how many hamburgers Mario can afford to buy, we need to solve the inequality:

2.90h + 4.75 ≤ 39.55

Subtracting 4.75 from both sides of the inequality:

2.90h ≤ 34.80

Next, divide both sides of the inequality by 2.90:

h ≤ [tex]\frac{34.80 }{ 2.90}[/tex]

Simplifying the right side:

h ≤ 12

Therefore, Mario can afford to buy a maximum of 12 hamburgers from the local store.

Answers

Step-by-step explanation:

remember the original trigonometric triangle inside the norm circle (radius = 1).

sine is the up/down distance from the triangle baseline or corresponding circle diameter.

cosine is the left/right distance from the center of the circle (and the point of the angle).

for larger triangles and circles all these function results need to be multiplied by the actual radius (which we skipped for the norm circle, as a multiplication by 1 is not changing anything).

when you look at the triangle with K representing the angle, we have 10 a the cosine value, 24 as the sine value and 26 as the radius.

so,

10 = cos(K) × 26

cos(K) = 10/26 = 5/13

In ΔSTU, u = 3. 4 cm, ∠S=6° and ∠T=93°. Find the area of ΔSTU, to the nearest 10th of a square centimeter

Answers

The area of ΔSTU is approximately 6.7 square centimeters.

What is the approximate area, in square centimeters, of ΔSTU given that u = 3.4 cm, ∠S=6°, and ∠T=93°?

To find the area of a triangle, we can use the formula A = (1/2)bh, where b is the base of the triangle and h is the height. In this case, we know that u is the base of the triangle, so we need to find the height.

To do this, we can use the sine function, which tells us that sin(6°) = h/u. Rearranging this equation, we get h = usin(6°). We can then substitute u and sin(6°) into the formula for the area to get

A = (1/2)(3.4)(3.4sin(6°)) ≈ 6.7 square centimeters.

In △abc , m∠b=20° and m∠c=40°. the angle bisector at a intersects side bc at point d. find the difference between bc and ab if ad = 1

Answers

In the △ABC, the  the difference between bc and ab if ad = 1 is found to be 0.709.

We can use the angle bisector theorem to solve this problem. Let's denote the length of segment BD as x and the length of segment CD as y. Then, we can write,

BD/DC = AB/AC

Using the angle bisector theorem, we know that AB/AC = BD/DC, so we can substitute to get,

x/y = AB/AC

We can solve for AB by multiplying both sides by AC,

AB = x/y * AC

Now, we can use the law of sines to find the length of AC. We have,

sin(20°)/AB = sin(140°)/AC

Solving for AC, we get,

AC = AB * sin(20°) / sin(140°)

Substituting the expression we found for AB, we get,

AC = x/yACsin(20°) / sin(140°)

Simplifying, we get,

y = xsin(140°) / (sin(20°) - sin(140°))

We know that AD = 1, so we can use the Pythagorean theorem to find BC:

BC² = BD² + CD²

Substituting the expressions we found for BD and CD, we get,

BC² = x² + y²

Substituting the expression we found for y, we get,

BC² = x² + (xsin(140°) / (sin(20°) - sin(140°)))²

Simplifying, we get,

BC² = x²(1+sin²(140°)/(sin²(20°)-2sin(20°)sin(140°)+sin²(140°)))

Using the identity sin(140°) = sin(180° - 40°) = sin(40°), we can simplify further.

Now, we can substitute x = AD = 1 and sing a calculator, we can evaluate this expression to get,

BC² ≈ 2.917

Taking the square root, we get,

BC ≈ 1.709

Therefore, the difference between BC and AB is 0.709.

In circle P with m \angle NPQ= 104m∠NPQ=104 and NP=9NP=9 units find area of sector NPQ. Round to the nearest hundredth

Answers

To find the area of the sector NPQ, we first need to find the measure of the central angle that intercepts the arc PQ. We know that the measure of angle NPQ is 104 degrees, and since it is an inscribed angle, its measure is half the measure of the central angle that intercepts the same arc. Therefore, the central angle measure is 208 degrees.

To find the area of the sector, we use the formula:

Area of sector = (central angle measure/360) x pi x radius^2

We know that the radius of circle P is NP = 9 units. Plugging in the values, we get:

Area of sector NPQ = (208/360) x pi x 9^2
= (0.5778) x 81pi
= 46.99 square units

Rounding to the nearest hundredth, the area of the sector NPQ is 47.00 square units.

Answers

If the terminal side of angle λ intersects the unit circle at point (-0. 358, 0. 934), the approximate decimal value of cot(λ) is -0.383.

To find the approximate decimal value of cot(λ), we first need to determine the values of x and y on the unit circle. Since the given point (-0.358, 0.934) lies on the unit circle, we can use the Pythagorean theorem to find the missing side:

x² + y² = 1
(-0.358)² + (0.934)² = 1
0.128 + 0.872 = 1
1 = 1

Therefore, we have x = -0.358 and y = 0.934. Since cot(λ) = cos(λ)/sin(λ), we can use the values of x and y to calculate the cosine and sine of λ:

cos(λ) = x = -0.358
sin(λ) = y = 0.934

Substituting these values into the formula for cot(λ), we get:

cot(λ) = cos(λ)/sin(λ) = -0.358/0.934 ≈ -0.383

Therefore, the approximate decimal value of cot(λ) is -0.383.

how many paths are there from point (0,0) to (90,160) if every step increments one coordinate and leaves the other unchanged and you want the path to go through (80,70)?

Answers

There are 4.097 x [tex]10^43[/tex] paths from (0,0) to (90,160) that pass through (80,70).

To calculate the number of paths from (0,0) to (90,160) while passing through (80,70), we need to break down the problem into smaller steps.

First, we can calculate the number of paths from (0,0) to (80,70) and then

multiply that by the number of paths from (80,70) to (90,160).

To go from (0,0) to (80,70), we need to take 80 steps to the right and 70 steps up, which gives us a total of 150 steps. The order in which we take these steps doesn't matter, so we can think of it as choosing 70 steps out of 150 to be up. This can be calculated using the binomial coefficient, which gives us (150 choose 70) = 2.364 x  [tex]10^43[/tex]

To go from (80,70) to (90,160), we need to take 10 steps to the right and 90 steps up, which gives us a total of 100 steps. Using the same method as above, the number of paths from (80,70) to (90,160) is (100 choose 10) = 17,310,309.

Multiplying these two values together, we get the total number of paths from (0,0) to (90,160) that pass through (80,70):

(2.364 x 10^34) x (17,310,309) = 4.097 x  [tex]10^43[/tex]

Patricia bought 4 apples and 9 bananas for $12. 70 Jose bought 8 apples and I bananas for $17. 70 at the same grocery store What is the cost of one apple?​

Answers

The cost of one apple is $2.15.

To find the cost of one apple, we can set up a system of equations with the given information. Let's use A for the cost of one apple and B for the cost of one banana:

1) 4A + 9B = $12.70
2) 8A + B = $17.70

Now, we can solve this system of equations. We can multiply equation 1 by 2 to match the number of apples in equation 2:

1) 8A + 18B = $25.40

Now subtract equation 2 from the modified equation 1:

(8A + 18B) - (8A + B) = $25.40 - $17.70
17B = $7.70

Now, divide by 17 to find the cost of one banana:
B = $7.70 / 17 = $0.45

Now that we know the cost of one banana, we can substitute B in equation 2 to find the cost of one apple:

8A + ($0.45) = $17.70
8A = $17.25
A = $17.25 / 8 = $2.15

So, the cost of one apple is $2.15.

Answers

The perimeter of the semicircular region is about 28.27 meters.

We know that the semicircular region is half of a circle.

Let's assume that the radius of the circle is r meters. Then the circumference of the circle is 2πr meters, and the perimeter of the semicircular region is half of that, which is πr meters.

We are given that the radius of the circle is 9 meters, so we can plug that in to get:

The perimeter of the semicircular region = πr

= π(9)

≈ 28.27

Rounding to the nearest hundredth, the perimeter of the semicircular region is about 28.27 meters.

find the extremum of each function using the symmetry of its graph. Classify the etremum of the function as maximum or a minimum and state the of x at which it occurs k(x)(300+10x)(5-0.2x)

Answers

The extremum of the function is a minimum at x = -2.5

The given function is k(x)(300+10x)(5-0.2x).

To check for symmetry about the y-axis, we replace x with -x in the given function and simplify as follows:

k(-x)(300-10x)(5+0.2x)

To check for symmetry about the x-axis, we replace y with -y in the given function and simplify as follows:

k(x)(300+10x)(5-0.2x) = -k(x)(-300-10x)(5+0.2x)

To find these points, we set the function equal to zero and solve for x:

k(x)(300+10x)(5-0.2x) = 0

This equation has three solutions:

x = 0

x = -30

x = 25.

The midpoint of the line segment connecting these points is

(x1+x2) ÷ 2 = (-30+25) ÷ 2 = -2.5.

To determine the type of extremum at this point, we need to check the sign of the second derivative. The second derivative of the function is:

k(x)(-1200+x)(0.2x+15)

Since the function is symmetric about the x-axis, the second derivative will be negative at the extremum if it is maximum and positive if it is a minimum.

When x = -2.5, the second derivative is positive, which means that the function has a minimum at x = -2.5.

The coach recorded the time it took 14 students to run a mile. The times are as follows: 9:23, 8:15, 9:23, 9:01, 6:55, 7:20, 9:14, 6:21, 7:12, 7:34, 6:10, 9:15, 9:18. Use the data set to complete the frequency table. Then use the table to make a histogram

Answers

The histogram for the frequency table is illustrated below.

To create the frequency table, we need to count how many times each time appears in the data set. The time 9:23 appears twice, so we would put a frequency of 2 in the row corresponding to 9:23. We do this for each time in the data set.

Here is the completed frequency table:

Time Frequency

6:10 1

6:21 1

6:55 1

7:12 1

7:20 1

7:34 1

8:15 1

9:01 1

9:14 1

9:15 1

9:18 1

9:23 2

As you can see, each time appears only once or twice in the data set. This tells us that there is no dominant time that most students ran the mile in.

To create the histogram, we'll draw a bar above each time on the x-axis with a height equal to the frequency of that time. For example, there are two times of 9:23, so we'll draw a bar above 9:23 with a height of 2.

As you can see, the histogram shows a relatively even distribution of times. The most common times are around 9 minutes, but there are also several times below 8 minutes and one time below 7 minutes.

At a show 4 adult tickets and 1 child ticket cost £33 2 adult tickets and 7 child tickets cost £36 Work out the cost of 10 adult tickets and 20 child tickets.​

Answers

Answer:

10 adult tickets cost £75 , 20 child tickets cost £60

Step-by-step explanation:

let a be the cost of an adult ticket and c the cost of a child ticket , then

4a + c = 33 → (1)

2a + 7c = 36 → (2)

multiplying (2) by - 2 and adding to (1) will eliminate a

- 4a - 14c = - 72 → (3)

add (1) and (3) term by term to eliminate a

0 - 13c = - 39

- 13c = - 39 ( divide both sides by - 13 )

c = 3

substitute c = 3 into either of the 2 equations and solve for a

substituting into (1)

4a + 3 = 33 ( subtract 3 from both sides )

4a = 30 ( divide both sides by 4 )

a = 7.5

the cost of an adult ticket is £7.50

then 10 adult tickets cost 10 × £7.50 = £75

the cost of a child ticket is £3

the cost of 20 child tickets is 20 × £3 = £60

What is the Pythagorean Theorem?

The Pythagorean Theorem states that in a right-angled triangle, the square of the length of the hypotenuse (the longest side) is equal to the sum of the squares of the lengths of the other two sides.

The theorem is expressed as follows:

c² = a² + b².

In which:

c is the length of the hypotenuse.a and b are the lengths of the other two sides (the legs) of the right-angled triangle.

The diagonal length is given as follows:

LN = OM = 46.

Half the diagonal is of:

PN = 0.5 x 46

PN = 23.

The diagonal is the hypotenuse of a right triangle of sides ON = MN = x, hence:

x² + x² = 46²

x² = 1058

[tex]x = \sqrt{1058}[/tex]

x = 32.5.

You find an apartment which charges $925 a month rent. each year the rent increases by 6%.

Answers

The monthly rent for the apartment would be $1238.84 in the fifth year.

What is the monthly rent for an apartment that charges $925 initially and increases by 6% each year?

The problem states that the monthly rent for an apartment is $925. To calculate the rent for the second year, we need to increase this amount by 6%.

To do this, we first need to calculate 6% of $925. We can do this by multiplying 0.06 (which is equivalent to 6%) by $925:

6% of $925 = 0.06 × $925 = $55.50

So, the rent for the second year would be:

$925 + $55.50 = $980.50

To find the rent for the third year, we need to increase the rent for the second year by 6%. We can follow the same process:

6% of $980.50 = 0.06 × $980.50 = $58.83

So, the rent for the third year would be:

$980.50 + $58.83 = $1039.33

To find the rent for any year n, we use the formula:

Rent for year n = $925 × (1 + 0.06)^n

In this formula, (1 + 0.06) represents the multiplier used to calculate the new rent each year.

For example, the multiplier for the second year is 1 + 0.06 = 1.06, and the multiplier for the third year is 1.06 × 1.06 = 1.1236 (rounded to four decimal places).

To find the rent for the fifth year, we plug in n = 5:

Rent for year 5 = $925 × (1 + 0.06)^5 = $925 × 1.3382 = $1238.84 (rounded to the nearest cent)

So, the monthly rent for the apartment would be $1238.84 in the fifth year.

c. Concluding that the bags are not being under filled when they actually are.


d. Concluding that the bags are not being under filled when they actually arenât.


e. None of these

Answers

Type I error in this situation would mean option a. Concluding that the bags are being under filled when they actually aren't.


A Type I error occurs when the null hypothesis (in this case, that the true mean net weight is 14 ounces) is rejected when it is actually true. In other words, it is the error of concluding that there is evidence for the alternative hypothesis (that the true mean net weight is less than 14 ounces) when there is not.

In this situation, if a Type I error is made, it would mean that the bags are being under filled (i.e. the true mean net weight is less than 14 ounces) when in reality they are not. This would lead to incorrect conclusions and potentially negative consequences for the manufacturer.

It's important to note that the probability of making a Type I error can be controlled by choosing an appropriate level of significance (usually denoted by alpha) for the hypothesis test. For example, if alpha is set at 0.05, there is a 5% chance of making a Type I error.

In summary, a Type I error in this situation would mean incorrectly concluding that the bags are being under filled when they actually are not, and the probability of making such an error can be controlled by choosing an appropriate level of significance for the hypothesis test.
