The antiderivative of f(x) = x/√x  is [tex](2/3)x^{3/2}  + C[/tex],  

where C is the constant of integration.

To find the antiderivative of the given function.

The function is: f(x) = x/√x

First, let's rewrite the function in a more convenient form for integration:
f(x) = x / √x

[tex]= x / x^{1/2}[/tex]

[tex]= x^{1 - 1/2}[/tex]

[tex]= x^{1/2}[/tex]
Now, let's find the antiderivative using the power rule for integration:
∫[tex]x^{1/2} dx[/tex]
To apply the power rule, we need to add 1 to the exponent and then divide by the new exponent:
Antiderivative = [tex](x^{(1/2) + 1)) / ((1/2) + 1} ) + C[/tex]
Antiderivative =[tex](x^{3/2/ 3/2} + C)[/tex]
Finally, multiply by the reciprocal to simplify the expression:
Antiderivative = [tex](2/3)x^{3/2} + C.[/tex].

An antiderivative, also known as an indefinite integral, is a function that, when differentiated, yields a given function. In other words, an antiderivative of a function f(x) is a function F(x) such that F'(x) = f(x).

For example, if f(x) = 2x, then an antiderivative of f(x) would be F(x) = x^2 + C,

The average rate of change per hour in the temperature is 0.83 degrees.

To find the average rate of change per hour, we need to divide the total change in temperature by the number of hours over which the temperature changed.

The temperature rose by 5 degrees from 6:00 am to 12:00 pm, which is a period of 6 hours.

Therefore, the average rate of change per hour can be calculated as follows:

average rate of change per hour = total change in temperature / number of hours

So, we have

average rate of change per hour = 5 degrees / 6 hours

average rate of change per hour = 0.83 degrees/hour (rounded to two decimal places)

So, the average rate of change per hour is 0.83 degrees.

Among the given options, the number of trials that comes closest to a large number is 200 trials (option D). Therefore, we would expect the experimental probability to be closest to 1/8 after 200 trials.

What is probability?

The probability of randomly choosing the number 5 from the bag of 8 cards is:

P(choosing 5) = number of 5 cards / total number of cards

Since there is only one card numbered 5 in the bag, the probability of choosing the number 5 is 1/8.

The experimental probability of choosing the number 5 after "n" trials can be calculated by counting the number of times the number 5 is chosen in "n" trials and dividing by "n".

For example, after 50 trials, we expect to choose the number 5 approximately:

P(choosing 5 after 50 trials) = number of times 5 is chosen in 50 trials / 50

We can simplify this expression as:

P(choosing 5 after 50 trials) = (1/8) x number of times 5 is chosen in 50 trials

Similarly, we can calculate the experimental probability for 100, 150, and 200 trials:

P(choosing 5 after 100 trials) = (1/8) x number of times 5 is chosen in 100 trials

P(choosing 5 after 150 trials) = (1/8) x number of times 5 is chosen in 150 trials

P(choosing 5 after 200 trials) = (1/8) x number of times 5 is chosen in 200 trials

To determine which number of trials would give us the experimental probability closest to 1/8, we need to consider the law of large numbers, which states that as the number of trials increases, the experimental probability approaches the theoretical probability.

Therefore, we would expect the experimental probability to be closest to 1/8 after a large number of trials. Among the given options, the number of trials that comes closest to a large number is 200 trials (option D). Therefore, we would expect the experimental probability to be closest to 1/8 after 200 trials.

In this scenario, the researcher is interested in comparing the effectiveness of three different doses of a new medication in treating panic attacks. To analyze the data, the researcher can use a hypothesis testing technique called analysis of variance (ANOVA).

ANOVA is a statistical technique used to compare the means of three or more groups to determine if there are significant differences between them. In this case, the means being compared are the number of panic attacks experienced by each group after 30 days on the medication.

The null hypothesis in this study would be that there is no significant difference in the mean number of panic attacks between the three dosage groups, and the alternative hypothesis would be that there is a significant difference in the mean number of panic attacks between at least two of the dosage groups.

The researcher can use a one-way ANOVA test to analyze the data, which will calculate the F-statistic and associated p-value. If the p-value is less than the chosen significance level (usually 0.05), the researcher can reject the null hypothesis and conclude that there is a significant difference in the mean number of panic attacks between at least two of the dosage groups.

If a significant difference is found, post-hoc tests such as Tukey's HSD can be used to determine which specific groups have significantly different means.

Based on data, it is better to describe the centers of distribution in terms of median because the data distribution is not symmetric. The Option B is correct.

To determine a better measure of center, we must examine the symmetry of the data distribution. We can do it by constructing box plots or dot plots but because we have small data set, we will examine the data visually.

By looking at the data, we see that those distributions are not perfectly symmetric with some values have more spread out than the others. So, it is better to describe the centers of distribution in median rather than in mean.

Yes, a normal distribution can be used to approximate the distribution of the random variable X, which counts the number of adults who have not visited a dentist in the last two years. This approximation can be done using the Central Limit Theorem (CLT), which states that if you have a large enough sample size, the distribution of the sample means will approach a normal distribution, regardless of the original distribution's shape.

To use a normal distribution for this approximation, you need to meet the following criteria:

1. The sample size (n) should be large enough, typically n > 30.
2. The random variable X should have a known mean (μ) and standard deviation (σ).

If these criteria are met, you can use the normal distribution to approximate the distribution of X by calculating the standard error (SE), which is equal to σ / √n. This will help you estimate probabilities and analyze the data for the number of adults who have not visited a dentist in the last two years.

In summary, using a normal distribution to approximate the distribution of the random variable X is possible through the Central Limit Theorem, as long as the sample size is large enough and the mean and standard deviation are known.

The best example of a defined benefits plan is: "a set amount an employee will receive at retirement".

In a defined benefits plan, the employer promises to pay employees a specific, predetermined amount of money upon retirement. This amount is typically based on factors such as the employee's salary and years of service. The employer is responsible for contributing to and managing the retirement fund, and the employee receives a guaranteed amount of money upon retirement, regardless of how the fund performs.

The other options listed are not examples of defined benefits plans. The wages and benefits an employee receives at a job are part of their compensation package and may include retirement benefits, but they do not guarantee a specific amount of money at retirement. The amount of pay an employee receives each hour is their hourly wage and is not related to retirement benefits. The money an employer puts into a retirement fund for each employee may be part of a defined benefits plan, but it is not a complete plan in and of itself.

What is a linear equation in mathematics?

A linear equation in algebra is one that only contains a constant and a first-order (direct) element, such as y = mx b, where m is the pitch and b is the y-intercept.

                         Sometimes the following is referred to as a "direct equation of two variables," where y and x are the variables. Direct equations are those in which all of the variables are powers of one. In one example with just one variable, layoff b = 0, where a and b are real numbers and x is the variable, is used.

In one hour, Roger can finish 1/6 of the work, and Trish can finish 1/5 of the work. So, working together for one hour, they can finish:

(1/6) + (1/5)

= (5/30) + (6/30)

Answer: the selling price of the sleeper sofa is $698, the markup is $460.15, and the net profit is $285.65.

Step-by-step explanation: Add up to fetched = fetched + overhead

Add up to fetched = $237.85 + $174.50

Add up to fetched = $412.35

Since the overhead is 25% of the offering cost, we are able utilize this data to discover the offering cost:

Overhead = 0.25 * Offering cost

Offering cost = Overhead / 0.25

Offering cost = $174.50 / 0.25

Offering cost = $698

The markup is the distinction between the offering cost and the taken a toll:

Markup = Offering cost - Fetched

Markup = $698 - $237.85

Markup = $460.15

The net benefit is the markup short the overhead:

Net benefit = Markup - Overhead

Net benefit = $460.15 - $174.50

Let's assume that Mitchell read x sports books last year. According to the problem, he read 5 mysteries for every 2 sports books, so he must have read (5/2)x mysteries.

We also know that he read 12 more mysteries than sports books, so:

(5/2)x - x = 12

Simplifying this equation, we get:

(3/2)x = 12

Multiplying both sides by 2/3, we get:

x = 8

So Mitchell read 8 sports books last year. To find out how many mysteries he read, we can use the equation we derived earlier:

(5/2)x = (5/2)(8) = 20

Therefore, Mitchell read 20 mysteries last year.
