The true statement about the sampling distribution is "the sampling distribution of a statistic is a distribution that we should approximate in exercise by taking many small samples."

The sampling distribution is the theoretical distribution of a statistic (including the imply, median, or variance) based totally on all viable samples of a given size that could be taken from a population. it is a beneficial idea in statistics as it allows us to make inferences approximately the populace based on records gathered from a pattern.

In practice, we can not examine the whole sampling distribution, as it's far based totally on all viable samples, which isn't always feasible to gain. but, we will approximate the sampling distribution by taking many small samples from the population and calculating the applicable statistic for every sample.

Because the variety of samples increases, the distribution of these data will converge to the sampling distribution, allowing us to make more accurate inferences approximately the population.

Both Tommy and Sophia can sell 162 tickets in 6 hours.

We have,

Tommy sold 36 tickets in 3 hours, so he sells:

36 tickets / 3 hours

= 12 tickets per hour

Sophia sold 60 tickets in 4 hours, so she sells:

60 tickets / 4 hours

= 15 tickets per hour

Now we can add up their ticket-selling rates to find their combined rate:

12 tickets/hour + 15 tickets/hour = 27 tickets/hour

So together, Tommy and Sophia can sell 27 tickets in one hour.

Now,

27 tickets/hour × 6 hours = 162 tickets

Therefore,

Both Tommy and Sophia can sell 162 tickets in 6 hours.

The angle of elevation of the sun is decreasing at a rate of  \(0.25 rad/hr\) then the shadow is increasing at the rate = \(100ft/hr\)

The angle of elevation is an angle that is formed between the horizontal line and the line of sight. If the line of sight is upward from the horizontal line, then the angle formed is an angle of elevation.

The angle of elevation of the sun is decreasing at a rate = \(0.25 rad/hr\)

The height of the building = \(400 ft-tall\)

We need to find the rate at which the shadow is increasing

d/dθ = 1/4 rad/hr at θ = π/4  

So,

We can write,

\(\frac{400}{x}\) = tan θ

x = 400/ tan θ

Upon derivation with t

\(\frac{dx}{dt}\) = 400 sec²θ/tan ²θ dθ/dt

at θ = π/4 and dθ/dt  = \(0.25 rad/hr\)

\(\frac{dx}{dt}\) = \(400 (2*3) * 0.25\)

\(\frac{dx}{dt}\) = \(100ft/hr\)

Therefore,  

The angle of elevation of the sun is decreasing at a rate of  \(0.25 rad/hr\) then the shadow is increasing at the rate = \(100ft/hr\)

Answer: Yes \(\angle FDE\) is one possible angle name

Another name is \(\angle EDF\)

When it comes to naming an angle this way, all we need to worry about is the vertex point. This is where the angle hinges (think of a door or a pair of scissors). In this case, the hinge or vertex point is at point D. The vertex is always the middle letter of any three-letter sequence. The order of the other two points does not matter.

This is why saying "angle FDE" is the same as "angle EDF".

Step-by-step explanation:

The linear inequality leads us to the conclusion that the silver pass will be more advantageous if a visitor stays at the theme park for more than three days.

Let the number of days be x.

So, cost of single pass for one day is 50 +10 = $60

cost of single pass for x days is 60x.

cost of silver pass for one day is 120 +20 = $140

cost of silver pass for x days is 120+20x.

Now, for silver pass to be worth to buy instead of single pass will be when it costs lesser than that of the single pass.

So,

Cost of silver pass < cost of single pass

120 + 20x < 60x

120 < 40x

x>3,

So, we can say conclude from the linear inequality that the silver pass will be more beneficial if someone is staying at amusement park for more than 3 days.

The critical value to be used in constructing the 99% confidence interval is 2.576.

Step 1: Finding the Critical Value

To determine the critical value for constructing a 99% confidence interval, we need to refer to the z-table or use a statistical calculator. The critical value corresponds to the desired level of confidence and takes into account the sample size.

Since the sample size is large (n = 77) and the population is assumed to be approximately normal, we can use the z-distribution to find the critical value. For a 99% confidence interval, the critical value is found by subtracting half of the desired confidence level from 1 and dividing the result by 2.

In this case, the calculation would be:

(1 - 0.99) / 2 = 0.005

The corresponding critical value is then determined by finding the z-score that has an area of 0.005 in the upper tail of the standard normal distribution. Consulting a z-table or using a statistical calculator, the critical value is approximately 2.576 (rounded to three decimal places).

Therefore, the critical value to be used in constructing the 99% confidence interval is 2.576.

The size of angle DAB in the quadrilateral is 49°.

The sum of the interior angles of a quadrilateral is 360°. We can say:

∠A + ∠B + ∠C + ∠D = 360°

∠A + 34° + ∠C + 228° = 360°

∠A  + ∠C + 262° = 360°

∠A  + ∠C = 360 - 262

∠A  + ∠C = 98

Since angles DAB and BCD are the same size. This implies ∠A  = ∠C. Thus:

∠A  + ∠A = 98

2∠A  = 98

∠A = 98/2

∠A  = 49°

Therefore, the size of angle DAB is 49°.

the velocity field is given by: \(u = Ax - 3Bxy^2, v = By^3\)

the pressure gradient is given by: ∇P = \((\rho By^3, -\rho Ax + 3\rho Bx*y^2)\)

What is velocity?

Velocity is a vector quantity that describes the rate at which an object changes its position with respect to time.

To find the velocity field and the pressure gradient from the given stream function, we can make use of the relationships between stream function, velocity components, and pressure gradient in two-dimensional flow.

The stream function (ψ) is related to the velocity components (u, v) as follows:

u = ∂ψ/∂y

v = -∂ψ/∂x

And the pressure gradient (∇P) is related to the stream function as follows:

∇P = -ρ (∂ψ/∂x, ∂ψ/∂y)

where ρ is the fluid density.

Given the stream function as \(y = Ax* - Bxy^3\), we can calculate the velocity components and the pressure gradient.

Velocity components (u, v):

Differentiating the stream function with respect to y:

∂ψ/∂y = \(Ax - 3Bx*y^2\)

Differentiating the stream function with respect to x:

∂ψ/∂x = \(0 - B*y^3\)

Now we can substitute these derivatives into the expressions for the velocity components:

u = ∂ψ/∂y = \(Ax - 3Bxy^2\)

v = -∂ψ/∂x = \(By^3\)

So, the velocity field is given by:

u = \(Ax - 3Bxy^2\)

v = \(By^3\)

Pressure gradient (∇P):

Using the relationship between pressure gradient and the stream function, we have:

∇P = -ρ (∂ψ/∂x, ∂ψ/∂y)

Substituting the derivatives of the stream function:

∇P = \(-\rho (-By^3, Ax - 3Bxy^2)\)

Simplifying, we get:

∇P = \(\rho(By^3, -Ax + 3Bxy^2)\)

So, the pressure gradient is given by:

∇P = \((\rho By^3, -\rho Ax + 3\rho Bx*y^2)\)

where ρ is the fluid density.

The probability of drawing a red marble is 2/10 or 1/5.

To determine this:

The probability of drawing a red marble is 2/10 or 1/5. This means that if we randomly select one marble from the jar, there is a 1 in 5 chance that it will be red.

The probability of an event is calculated by dividing the number of favorable outcomes by the number of possible outcomes. For example, if you flip a fair coin, the probability of getting heads is 1/2 because there are two possible outcomes (heads or tails) and only one of them is favorable (heads).
