Therefore, to ensure with probability 0.9 that the class average would be within 5 of 60, the professor would need 118 students to take the final exam.

The Central Limit Theorem states that the distribution of the sum or average of a large number of independent, identically distributed variables will be approximately normal, regardless of the underlying distribution.

Therefore, in this example we can use the Central Limit Theorem to approximate the mean of the test scores of the students taking the final exam. If the professor knows that the mean of the test scores is 60 and the standard deviation is 16, then the professor can calculate the sample size necessary to ensure that the class average is within 5 of 60 with a probability of 0.9.

Using the formula \(n = (zα/2 * σ/ε)2\), where zα/2 is the z-score associated with a confidence level of 0.9, σ is the standard deviation of the population, and ε is the margin of error desired, we can calculate the sample size necessary for this professor.

Given that Elana sells 3a adult tickets. The number of adult tickets that Elana sells is 15. The question is whether Elana sells at least 100 total tickets.

Elana sells 3a adult tickets, where a is the number of tickets sold. Therefore, the number of adult tickets Elana sells is 3a = 15. Dividing both sides by 3, we geta = 5So, Elana sells 5 adult tickets. To find out whether Elana sells at least 100 tickets, we need to know the number of non-adult tickets sold.

If we assume that all tickets are either adult or non-adult, we can say that the total number of tickets sold is 5 + n, where n is the number of non-adult tickets sold. Since we don't know the value of n, we cannot determine if the total number of tickets sold is at least 100. Thus, the answer to the question is not clear from the information provided.

Step-by-step explanation:

Answer:

Step-by-step explanation:

To find Length or Breadth when Area of a Rectangle is given

When we need to find length of a rectangle we need to divide area by breadth.

Length of a rectangle = Area ÷ breadth.

ℓ = A ÷ b.

Similarly, when we need to find breadth of a rectangle we need to divide area by length.

Breadth of a rectangle = Area ÷ length.

Answer:

The width of the rectangle is x + 3.

Step-by-step explanation:

Area of the rectangle = 4x² + 12x

Length of the rectangle = 4x

Width of the rectangle = ?

So,

↬ Area = Length × Width

Now,

4x² + 12x = 4x × Width

4x² + 12x ÷ 4x = Width

x + 3 = Width

Width = x + 3

Thus, The width of the rectangle is x + 3.

In a randomized controlled experiment, there is a control group and a treatment group.

This statement is i.e. option d is correct.

Randomized controlled experiments are commonly used in scientific research, particularly in medicine and psychology.

They are used to determine whether a treatment or intervention is effective or not.

In a randomized controlled experiment, the participants are randomly assigned to either the control group or the treatment group.

The control group is used as a comparison group and does not receive the treatment or intervention.

The treatment group, on the other hand, receives the treatment or intervention being studied.

There are several ways that a randomized controlled experiment can be designed to minimize the potential for bias. For example, in a randomized controlled experiment, random assignment of participants to groups helps to ensure that the two groups are similar at the outset of the study.

This reduces the likelihood that differences between the groups will be due to factors other than the treatment or intervention being studied.

Other ways that a randomized controlled experiment can be designed to minimize bias include blinding and use of placebos.

Blinding refers to the practice of keeping certain participants, such as those administering the treatment, unaware of which group a participant is in.

This helps to ensure that any differences between the two groups are not due to the expectations of the researchers or participants.

Use of placebos is another way to reduce bias in a randomized controlled experiment.

Placebos are inactive substances that are given to the control group to mimic the treatment group, ensuring that any differences between the groups are due to the treatment being studied and not other factors.

\(X= (-4,-2)\)

\(Z = (-6,-6)\)

\(Y =(-3,-7)\)

Rotation across 180 degrees

Reflection across y-axis

Required

The true statement

Using point W as a point of reference; We have:

\(W = (-7,-2)\)

1. Rotation across 180 degrees

The rule is:

\((x,y) \to (-x,-y)\)

So:

\(W(-7,-2) \to W'(7,2)\)

2. Reflection across y-axis

The rule is:

\((x,y) \to (-x,y)\)

So:

\(W'(7,2) \to (-7,2)\)

Using the above transformation on the other points; We have:

\(W(-7,-2) \to W"(-7,2)\)

\(X (-4,-2) \to X "(-4,2)\)

\(Z (-6,-6) \to Z" (-6,6)\)

\(Y(-3,-7) \to Y"(-3,7)\)

Answer:

Step-by-step explanation:

The volume V of a cube with side length x is given by:

V = x^3

We want to find how fast the side length x is changing with respect to time, or dx/dt, when x = 3, given that the volume is increasing at a rate of 2 ft^3/min. This can be found using the chain rule of differentiation:

dV/dt = d/dt(x^3) = 3x^2(dx/dt)

Rearranging, we get:

dx/dt = (1/3x^2)(dV/dt)

Substituting x = 3 and dV/dt = 2 ft^3/min, we get:

dx/dt = (1/3(3)^2)(2 ft^3/min) = (2/27) ft/min

Therefore, when the side length of the cube is 3 feet and the volume is increasing at a rate of 2 ft^3/min, the side length is changing at a rate of (2/27) ft/min.

Answer:  When x = 3 ft, the side length of the cube is changing at a rate of 2/9 ft/min.

Step-by-step explanation:

The volume of a cube with side length x is given by V = x^3.

We are given that the volume V is changing with respect to time t at a rate of 2 ft^3/min. We want to find the rate of change of the side length x with respect to time when x = 3.

Using the chain rule, we have:dV/dt = d/dt(x^3) = 3x^2 (dx/dt)We can solve for dx/dt:dx/dt = (1/3x^2) dV/dtWhen x = 3, the volume of the cube is V = (3 ft)^3 = 27 ft^3. Therefore, dV/dt = 2 ft^3/min.

Substituting x = 3 and dV/dt = 2 into the equation above, we get:dx/dt = (1/3(3^2)) (2) = 2/9 ft/min

Therefore, when x = 3 ft, the side length of the cube is changing at a rate of 2/9 ft/min.

By using the Cauchy-Riemann equations on a real-valued function, it can be proven that the function f(z) is constant in the domain D. This is important for understanding analytic functions in complex analysis.

To prove that if f(z) is real-valued for all z in D, then f(z) must be constant throughout D, let a function f be analytic everywhere in a domain D. We know that a real-valued function is said to be a function whose values lie on the real line. In the case of the complex plane, a function whose values lie on the real line is real-valued.

The Cauchy-Riemann equations, which define the necessary conditions for a function f(z) to be analytic in a domain, say that the imaginary component of f(z) is determined by its real component.

To be more precise, if f(z) is real-valued for all z in D, then we can say that:u(x, y) = f(z),v(x, y) = 0

By definition, the Cauchy-Riemann equations can be stated as:

∂u/∂x = ∂v/∂y∂u/∂y = -∂v/∂x

Taking the first equation, we get:

∂u/∂x = ∂v/∂y => ∂v/∂y = 0

Since v is equal to 0 for all values of x and y, the above equation reduces to ∂u/∂x = 0, which implies u is constant with respect to x.

Similarly, taking the second equation, we get:

∂u/∂y = -∂v/∂x => ∂u/∂y = 0

Since u is equal to a constant for all values of x and y, the above equation reduces to ∂v/∂y = 0, which implies v is constant with respect to y. Since u and v are both constant with respect to their respective variables, u + iv = f(z) is a constant with respect to z throughout the domain D. Thus, we have proved that if f(z) is real-valued for all z in D, then f(z) must be constant throughout D.
