Answer:

\(4298.66mm^{2}\), or \(1369mm^{2}\)\(\pi\)

Step-by-step explanation:

Use the formula for area of a circle

A = \(\pi\)\(r^{2}\)

the radius is half the diameter, so divide 74 by 2 then substitute it as r

A = \(\pi 37mm^{2}\)

multiply 37 by 37

A = \(1369mm^{2} \pi\)

multiple 1369 by pi(3.14)

\(1369mm^{2} \pi\) or \(4298.66mm^{2}\)

The hypothesis that is typically used to test the claim is the null hypothesis, which asserts that the average time spent by students studying for a midterm exam is indeed 3 hours. The alternative hypothesis would be that the average time spent is either greater or less than 3 hours.

The null hypothesis is usually denoted as H0 and the alternative hypothesis as Ha. In this case, we can write:

H0: The average time spent by students studying for a midterm exam is 3 hours.

Ha: The average time spent by students studying for a midterm exam is not 3 hours.

To test this hypothesis, a statistical test can be performed, such as a t-test or a z-test, depending on the sample size and the population parameters. The results of the test will determine whether the null hypothesis can be rejected or not. If the null hypothesis is rejected, it means that there is evidence to suggest that the average time spent studying is different from 3 hours. If the null hypothesis is not rejected, it means that there is not enough evidence to suggest that the average time spent studying is different from 3 hours.

the probability of transitioning from state 1 to state 2 after the first transition is:

P(X(t) enters state 2 after the first transition | X(0) = 1) = 1 / 3

To write the system of ordinary differential equations (ODEs) for the transition probabilities Pᵢⱼ(t) of the given continuous-time Markov chain, we need to consider the rate at which the system transitions between different states.

Let Pᵢⱼ(t) represent the probability that the Markov chain is in state j at time t, given that it started in state i at time 0.

The ODEs for the transition probabilities can be written as follows:

dP₁₂(t)/dt = q₁₂ * P₁(t) - q₂₁ * P₂(t)

dP₁₃(t)/dt = q₁₃ * P₁(t) - q₃₁ * P₃(t)

dP₂₁(t)/dt = q₂₁ * P₂(t) - q₁₂ * P₁(t)

dP₂₃(t)/dt = q₂₃ * P₂(t) - q₃₂ * P₃(t)

dP₃₁(t)/dt = q₃₁ * P₃(t) - q₁₃ * P₁(t)

dP₃₂(t)/dt = q₃₂ * P₃(t) - q₂₃ * P₂(t)

where P₁(t), P₂(t), and P₃(t) represent the probabilities of being in states 1, 2, and 3 at time t, respectively.

Now, let's consider the second part of the question: Suppose that the initial state is 1. We want to find the probability that after the first transition, the process X(t) enters state 2.

To calculate this probability, we need to find the transition rate from state 1 to state 2 (q₁₂) and normalize it by the total rate of leaving state 1.

The total rate of leaving state 1 can be calculated as the sum of the rates to transition from state 1 to other states:

total_rate = q₁₂ + q₁₃

Therefore, the probability of transitioning from state 1 to state 2 after the first transition can be calculated as:

P(X(t) enters state 2 after the first transition | X(0) = 1) = q₁₂ / total_rate

In this case, the transition rate q₁₂ is 1, and the total rate q₁₂ + q₁₃ is 1 + 2 = 3.

Therefore, the probability of transitioning from state 1 to state 2 after the first transition is:

P(X(t) enters state 2 after the first transition | X(0) = 1) = 1 / 3

Step-by-step explanation:

Casho + her 2 kids would equal 3 people in total.

The tickets are $13 each.

13 x 3 = 39

Snacks are available for $5 each.

"How much total money would Casho have to pay for her family if she were to buy 4 snacks for everybody to share?"
To solve this question, you'd set up this expression: 39 + 5(4)

39 + 5(4)

39 + 20 = 59

"How much would Casho have to pay if she bought a snacks for everybody to share?"

Assuming a is a variable, you would set up a similar expression to the question before.

39 + 5a

Assuming a means 1, you would set up a similar expression to the question before.

39 + 5(1) = 39 + 5 = 44

Casho have to pay total  $59.

A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.

Variables are the name given to these symbols because they lack set values.

In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.

Given:

Each movie ticket costs $13.

Total people= 2 +1 = 3

So, the cost of tickets for 3 people= 13 x 3= $39

Now, Cost of Snacks= 5

Cost of 4 Snacks = 5 x 4= $20

Thus, Casho have to pay total = 39 + 20 = $59

Step-by-step explanation:

If there are 36 gallons per 3 min. To find the per min you would divide 36 by 3.

The probability that the drug lasts less than 220 minutes for a random sample of 10 people is 0.0571, or about 5.71%.

To solve this problem, we need to use the normal distribution formula and the central limit theorem. The formula for the standard normal distribution is:

z = (x - μ) / σ

where z is the z-score, x is the observed value, μ is the mean, and σ is the standard deviation.

In this case, we want to find the probability that the drug lasts less than 220 minutes (3 hours and 40 minutes) for a random sample of 10 people. To do this, we first need to calculate the sample mean and the sample standard deviation.

The sample mean is the same as the population mean, which is 240 minutes:

μ = 240 minutes

The sample standard deviation is given by the formula:

σ = population standard deviation / sqrt(sample size)

σ = 40 minutes / sqrt(10) = 12.65 minutes (rounded to the nearest hundredth)

Now, we can calculate the z-score for a drug duration of 220 minutes:

z = (220 - 240) / 12.65 = -1.58 (rounded to the nearest hundredth)

We can use a standard normal distribution table or a calculator to find the probability that the z-score is less than -1.58. The probability is approximately 0.0571 (rounded to the nearest ten-thousandth).

Therefore, the probability that the drug lasts less than 220 minutes for a random sample of 10 people is 0.0571, or 5.71%.

In 7 years, the population of the town will reach 24600.

Formula for population growth can be expressed as;

N = N₀ × e^(rt)

Where N is the future population, N₀ is the initial population, t is time and r is rate of growth.

Given the data in the question;

First, convert the rate from percent to decimal.

Growth rate r = 3%

Growth rate r = 3/100

Growth rate r = 0.03

Now, plug the given values into the above  population growth formula and solve for t.

N = N₀ × e^(rt)

t = ln( N/N₀ ) / r

t = ln( 24600 / 15000  ) / 0.03

t = 17 years.

The probability that the first guest will take a chair in the front row of the small auditorium is 2/7 or approximately 0.2857.

To find the probability that the first guest will take a chair in the front row, we need to determine the total number of chairs and the number of chairs in the front row.

Given that there are 12 chairs in the front row, 14 chairs in the middle row, and 16 chairs in the back row, the total number of chairs in the auditorium is:

Total chairs = 12 + 14 + 16 = 42

Now, since the first guest can choose any chair, and there are a total of 42 chairs, the probability of the first guest taking a chair in the front row is:

Probability = Number of favorable outcomes / Total number of outcomes

The number of favorable outcomes is the number of chairs in the front row, which is 12. The total number of outcomes is the total number of chairs in the auditorium, which is 42.

Probability = 12 / 42

Simplifying the fraction, we have:

Probability = 2 / 7

Therefore, the probability that the first guest will take a chair in the front row is 2/7 or approximately 0.2857.

In the special case of two degrees of freedom, the chi-squared distribution does not coincide with the exponential distribution. The chi-squared distribution is a continuous probability distribution that arises in statistics and is used in hypothesis testing and confidence interval construction. It is defined by its degrees of freedom parameter, which determines its shape.

On the other hand, the exponential distribution is also a continuous probability distribution commonly used to model the time between events in a Poisson process. It is characterized by a single parameter, the rate parameter, which determines the distribution's shape.

While both distributions are continuous and frequently used in statistical analysis, they have distinct properties and do not coincide, even in the case of two degrees of freedom. The chi-squared distribution is skewed to the right and can take on non-negative values, while the exponential distribution is skewed to the right and only takes on positive values.

The chi-squared distribution is typically used in contexts such as goodness-of-fit tests, while the exponential distribution is used to model waiting times or durations until an event occurs. It is important to understand the specific characteristics and applications of each distribution to appropriately utilize them in statistical analyses.

The percentage of IQs that would be over 80 is 68%.

Step-by-step explanation:

The percentage of IQs that would be over 80 is 68%.

This is because 68% of the population falls within one standard deviation of the mean on a normal distribution. In this case, the mean is 100 and the standard deviation is 16, so 68% of the population has an IQ between 84 and 116.

The remaining 32% of the population falls outside of one standard deviation of the mean. 16% of the population has an IQ below 84 and 16% of the population has an IQ above 116.

The mean is represented by the dotted line in the center of the graph. The standard deviation is represented by the two dotted lines on either side of the mean. The shaded area represents the 68% of the population that has an IQ between 84 and 116.
