When all samples are drawn from a single population, the mean of the distribution of differences should approximate 0.

When samples are drawn from a single population, the differences between pairs of samples should reflect the inherent variability within that population. If the population has a well-defined mean, the differences between pairs of samples will tend to cancel out, resulting in an average difference close to zero.

This is because the positive differences will be balanced by the negative differences, leading to an overall mean difference of approximately zero.

Therefore, option a, "0," is the correct answer. The mean of the distribution of differences should approach zero when all samples are drawn from a single population.

The expected number of education majors in the sample can be found using the concept of expected value. In this scenario, there are 110 education majors out of a total of 350 freshmen in the population. We want to determine the expected number of education majors when a sample of 70 freshmen is randomly selected (without replacement).

Expected number of education majors = (Number of education majors in the population / Total number of students in the population) * Number of students in the sample Expected number of education majors = (110 / 350) * 70 , Expected number of education majors = 12.86.This means that we would expect to see 12.86 education majors in the sample of 70 freshmen. The expected number of education majors in the sample is less than the actual number of education majors in the population because the sample is drawn without replacement. This means that there is a chance that some of the education majors will be selected more than once, while others will not be selected at all.

Answer:

c=20

Step-by-step explanation:

A hypothesis is a statement regarding a characteristic of one or more populations. The null hypothesis is a statement of no change, no effect, or no difference. The alternative hypothesis is a statement we are trying to find evidence to support.

Generally, the null hypothesis expresses that there is no change, no difference, no effect, and in another way, no relationship between the independent and dependent variables. Because we are hypothesizing that nothing is happening, then it is called the null hypothesis.

The null and alternative hypothesis are two conflicting claims which researchers weigh evidence for and against using a statistical test. Null hypothesis (H0) means there is no effect in the population. Meanwhile, alternative hypothesis (Ha or H1) means there is an effect in the population.

The probability that the sum of the two dice is 10 is 1/20 or 0.05.

The probability that the sum of the two dice is 10 is determined as follows:

Outcomes:

Ten-sided die outcomes: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10

Four-sided die outcomes: 1, 2, 3, 4

The possible sums of 10:

(1, 9)

(2, 8)

(3, 7)

(4, 6)

(5, 5)

For the ten-sided die, there are 10 possible outcomes, so the probability of each outcome is 1/10.

For the four-sided die, there are 4 possible outcomes, so the probability of each outcome is 1/4.

The probability of each pair

(1/10) * (1/10) = 1/100

(1/10) * (1/10) = 1/100

(1/10) * (1/10) = 1/100

(1/10) * (1/10) = 1/100

(1/10) * (1/10) = 1/100

The probability of the sum of 10 will be:

(1/100) + (1/100) + (1/100) + (1/100) + (1/100) = 5/100

The probability of the sum of 10 = 1/20

Answer:

Step-by-step explanation:

To find the ticket price that would maximize revenue, we would need to find the ticket price that results in the highest attendance and multiply that by the attendance rate.

To maximize revenue, the ticket price should be set where the attendance rate is highest. If attendance is linearly related to ticket price, we can use the two points of ($8, 29000) and ($7, 34000) to find the slope of the line and use it to find the price that would result in the maximum attendance. To find the slope, we can use the formula:

Slope = (y2 - y1) / (x2 - x1)

where y1 is the attendance at $8 and y2 is the attendance at $7. x1 is the ticket price of $8 and x2 is the ticket price of $7. Plugging in the values, we get:

Slope = (34000 - 29000) / (7 - 8) = 5000 / -1 = -5000

This means that for every $1 decrease in ticket price, attendance will increase by 5000. Using this slope, we can write the equation of the line as:

Attendance = -5000 * (Ticket Price) + 34000

where Ticket Price is the price of the ticket. To find the maximum revenue, we need to find the ticket price that results in the highest attendance. To do this, we can use the equation to calculate attendance for different ticket prices and choose the one that results in the highest attendance. The revenue is equal to the product of the ticket price and the attendance. To maximize the revenue, we want to maximize the product of these two values.

Therefore, to find the ticket price that would maximize revenue, we would need to find the ticket price that results in the highest attendance and multiply that by the attendance rate.

Answer:

The maximum number of boxes that will fit on the shelf = 189 boxes

Step-by-step explanation:

First, to harmonize the units of the dimensions given, let us convert the unit of the Pick-Me-Up teabags to cm.

1 cm = 10mm

1mm = 0.1cm

∴ 120mm = 0.1 × 120 = 12cm

Therefore, the base of each box is 12cm²

Next, let us calculate the area of the shelf.

Dimension of shelf = 65cm × 35cm

∴ Area of shelf = 65 × 35 = 2275cm²

Therefore, to calculate how many boxes will fit into the shelf, we will divide the area of the shelf by the area of the boxes of Pick-Me-Up teabag. This is shown below.

Area of shelf = 2275cm²

Area of boxes = 12cm²

Number of boxes that will fit on the shelf = Area of shelf ÷ Area of boxes

= 2275 ÷ 12 = 189.58 boxes

since there are no fractional boxes, we will round down to the nearest whole number of boxes.

Hence, the maximum number of boxes that will fit on the shelf = 189 boxes

Using line tangent, the approximation for f(2.1) is 3.95

Given,

The point (a, f(a)) is on the line tangent to the graph of y = f(x) at x = a, which has a slope of f'(a).

The equation be like;

y - f(a) / (x - a) = f'(a)

y = f'(a) (x - a) + f(a)

Using the provided data and a = 2, we can determine that the tangent line to the graph of y = f(x) at x = 2 has equation

y = f'(2) (x - 2) + f(2)

y = -1/2 (x - 2) + 4

To compute a "approximation of f(2.1) using the line tangent to the graph of f at x = 2," one must substitute x = 2.1 for f in the equation for the tangent line (2.1). You get 2.1 when you plug this in.

y = -1/2 (x - 2) + 4

y = -1/2 (2.1 - 2) + 4

y = -1/2 x 0.1 + 4

y = 3.95

Step-by-step explanation:

scalene is no equal sides and obtuse is an angle greater than 90°

To determine which point is a solution to which equation system, you have to identfy which line corresponds to which equation and the coordinates of each point.

Points

W (≈-7/3,≈4/3)

X (-1,3)

Y (1,1)

Z (≈-1/2,-2)

The symbol ≈ indicates that is an approximate value.

Brown line

Has y-intercept at (0,-3)

And slope

Using points (0,-3) and (-1,-1)

Its equation is y=-2x-3

Blue line

Has y-intercept (0,2)

And slope

Using points (0,2) and (-1,-3)

Its equation is y=-x+2

Red line

Has y-intercept (0,4)

And slope

Using points (0,4) and (-1,-3)

Its equation is y=x+4

Black line

Has y-intercept (0,-1)

And slope

Using points (0,-1) and (1,1)

The equation for this line is y=2x-1

The first equation system is

y=-2x-3

y=2x-1

Corresponds to the intersection between the brown and black lines. The point that is a solution for this system is Z

The second equation system is

y=x+4

y=-x+2

Corresponds to the intersection between the blue and red lines. The point that is a solution for this system is X

The third equation system is

y=-2x-3

y=x+4

Corresponds to the intersection between the brown and red lines. The point that is a solution for this system is W

The fourth equation system is

y=2x-1

y=-x+2

Corresponds to the intersection between the black and blue lines. The point that is a solution for this system is Y

Another way for solving this exercise is by calculating the solution of each system and placing the results in the grid. For example for the first system:

y=-2x-3

y=2x-1

solve for x

And now replace this value in one of the equations

The solution for this system is (-1/2,-2) → If you look at the coordinates determined above, you'll see that these correspond to point Z

Both ways are equally valid to determine which point corresponds to each system.

Answer:

The angles are adjacent because they have a common side and vertex. Basically, they are both right next to each other.

x = 28

Step-by-step explanation:

When (x + 6)° and 56° are added together, they need to equal 90° since they are both parts of a right angle.

(x + 6) + 56 = 90

x + 62 = 90

x = 28

The missing angle of the diagram is expressed as; x = 70°

An angle is usually measured with reference to a circle with its center at the common endpoint of the rays. Hence, the sum of angles at a point is always 360 degrees

Now, we are given a point with three angles where one is unknown and the other two are known. Thus, by the sum of angles about a point, they will sum up to 360 degrees.

Thus;

x + 160 + 130 = 360

x + 290 = 360

x = 360 - 290

Step-by-step explanation:

The main answer to this question is that there could be several reasons why an experiment may not produce significant results even if the research hypothesis is true.

One possible explanation could be that the sample size used in the experiment was too small, which could have resulted in insufficient statistical power to detect the true effect of the independent variable on the dependent variable. Another explanation could be that there were extraneous variables that were not controlled for in the experiment, which could have influenced the results and made it difficult to detect the true effect of the independent variable.

it is important to consider all possible factors that may affect the results of an experiment and to take steps to minimize their impact. This includes ensuring that the sample size is appropriate, controlling for extraneous variables, and using appropriate statistical tests to analyze the data. By doing so, researchers can increase the likelihood of obtaining significant results that accurately reflect the effects of the independent variable on the dependent variable.
