Answer:

B)

Step-by-step explanation:

625:250=2.5

so i think it is B

Answer:

A 2:3

Step-by-step explanation:

625-250= 375 which is the number of boys in the school now it's 375 and 250

250:375

= 250/375

Dividing by 5/5, we have,

50/75

Again, Dividing by 5/5, we have,

10/15

Again, Dividing by 5, we have,

2/3

Hence, the ratio 250:375 in the simplest form will be 2:3

Answer:

Isolate the variable by dividing each side by factors that don't contain the variable

Exact Form:

A correct statement about sampling distributions is: Sampling distributions of means get closer to normality as the sample size increases.

The correct answer is an option (A)

In this question we have been given few statements.

We need to select a correct statement about sampling distributions.

We know that the sampling distribution is nothing but a probability distribution that is obtained through repeated sampling of a specific population.

Also according to central limit theorem, sampling distribution of means approaches normal when the sample size increases.

Therefore Sampling distributions of means get closer to normality as the sample size increases.

Answer:

1/ Point slope form is more efficient for determining the Slope

2/ Standard form is more efficient for determining x-intercept and

y-intercept

3/ If you want to use your calculator to graph an equation, the Point slope form is more efficient

Step-by-step explanation:

1/ I say point slope form because the slope in this form is a point on the line, and he if knows the point on the graph and slope, he can graph the line easily.

2/ I say standard form because x​ and ​y​ intercepts ​ of a graph, that is, the point where the graph crosses the ​ x-axis and the point where it crosses the ​ y ​-axis. So, it is the easiest form to find the x and y intercepts.

3/ If he knows a point and the slope he can graph it easily.

Considering U = {x l x is a positive integer greater than 1} the empty set will be

Between 20 and 40 units per hour, the long-run average cost curve exhibits constant returns to scale. The statement that indicates between 20 and 40 units per hour, the long-run average cost curve exhibits constant returns to scale. This is option B.

In microeconomics, the long-run average cost (LRAC) is a method of showing the average expense per unit for a given level of production input. It is the cost of producing goods per unit using a specified number of inputs, such as labor and capital.

Long-run average cost is the average cost per unit of production after the company has adapted its production scale fully. As a result, the term "long-run" denotes a period in which all of the firm's inputs are variable.

The cost structure's shape is represented by the long-run average cost curve. The curve is determined by dividing the cost of producing goods by the number of goods produced. It aids in identifying the production rate at which a firm may generate the most output at the lowest cost.The long-run average cost curve depicts how the average cost of production varies with scale.

The curve might be downward-sloping, indicating economies of scale, flat, implying constant returns to scale, or upward-sloping, indicating diseconomies of scale, based on the company's production methods.

Hence, the answer is B.

a. The equilibrium interest rate,  is determined by the risk-free interest rate, the probability of repayment, and the cost of default.

b. The probability of the government repaying its loan can be calculated using the loan repayment threshold and the distribution of the output.

c. If the interest rate, r, is equal to or greater than the equilibrium interest rate, the borrowing country would default.

a. To find the equilibrium interest rate,  we need to consider the risk-free interest rate, the probability of repayment, and the cost of default. The equilibrium interest rate is given by the formula: r = r + (c/p), where r is the risk-free interest rate, c is the cost of default, and p is the probability of repayment.

b. The probability that the government will repay its loan can be calculated by determining the percentage of the output distribution that exceeds the loan repayment threshold. Since 0.5 of the output is required to repay the loan, we need to calculate the probability that the output exceeds L/0.5.

c. If the interest rate, r, is equal to or greater than the equilibrium interest rate, the borrowing country would default. This can be proven by comparing the repayment threshold (L/0.5) with the loan repayment amount (L + Lr). If the repayment threshold is greater than the loan repayment amount, the borrowing country would default.

The scenarios where data should be collected through an experiment rather than an observational study are:

C) An artist wishes to determine which detergent will best remove paint stains from their aprons.

D) A pharmaceutical company wishes to determine if a new medication will be effective for treating inflammation.

In these scenarios, controlled experiments can be conducted to gather data and make causal inferences. In Scenario C, the artist can compare the effectiveness of different detergents by applying paint stains to aprons and testing each detergent's ability to remove the stains.

This requires controlling variables such as the type of detergent, application method, and stain intensity.

In Scenario D, the pharmaceutical company can conduct randomized controlled trials (RCTs) to compare the effectiveness of the new medication in treating inflammation.

They can randomly assign participants to treatment and control groups, administer the medication to the treatment group, and compare the outcomes between the two groups while controlling for confounding factors.

In both cases, experiments allow for direct manipulation of variables and provide a stronger basis for establishing cause-and-effect relationships compared to observational studies. The correct answer is c and d.

Answer: Let the width of the rectangle be w and the length be l. We are given that the area of the rectangle is 45 cm^2, so we can write the equation:

w * l = 45

To find the lengths of the sides, we need to solve for w and l. We can divide both sides of the equation by any non-zero number to find an equivalent expression. For example, we can divide both sides by 9:

(w/9) * (l/9) = 45/9

Simplifying, we get:

w/9 * l/9 = 5

So, w/9 = 5/l and w = 5l/9.

Substituting the expression for w into the original equation, we get:

(5l/9) * l = 45

Expanding and simplifying, we get:

5l^2/9 = 45

Multiplying both sides by 9, we get:

5l^2 = 405

Dividing both sides by 5, we get:

l^2 = 81

Taking the square root of both sides, we get:

l = 9

So, the length of the rectangle is 9 cm. To find the width, we can substitute the value of l back into the expression we derived earlier:

w = 5l/9

w = 5 * 9 / 9

w = 5

So, the width of the rectangle is 5 cm.

The lengths of the sides of the rectangle, both exactly and approximately, are 9 cm and 5 cm.

The probability that at least one of three randomly selected people has been vaccinated in a large population where 64% of people have been vaccinated is 0.784.

The probability that at least one of three randomly selected people has been vaccinated in a large population where 64% of people have been vaccinated can be calculated using the binomial probability formula.

The binomial probability formula is used to calculate the probability of a given number of successes from a given number of trials when the probability of success is constant. In this case, the number of trials is 3 (i.e. the three randomly selected people) and the probability of success is 64% (i.e. the probability that each of the randomly selected people has been vaccinated).

To calculate the probability that at least one of the three randomly selected people has been vaccinated, we first calculate the probability of none of them having been vaccinated:
P(none) = (1 - 0.64)^3 = 0.216

Then, the probability of at least one of them having been vaccinated is 1 - P(none) = 1 - 0.216 = 0.784.

In conclusion, the probability that at least one of three randomly selected people has been vaccinated in a large population where 64% of people have been vaccinated is 0.784.

What is the standard deviation?

The standard deviation in statistics is a measure of the amount of variation or dispersion in a set of values. A low standard deviation indicates that the values are close to the set's mean, whereas a high standard deviation indicates that the values are spread out over a wider range.

Standard deviation determines how far numbers deviate from the mean. The Standard deviation of the two sets will be the same if the numbers from the respective means are placed in the same order.
