A. The confidence interval estimate of the expected value of y will be wider than the prediction interval is correct.

A confidence interval gives an estimated range of a population parameter based on a sample. It is calculated by taking a sample of the population and using statistical methods to estimate the range in which the true population parameter would fall, with a certain level of confidence.

On the other hand, a prediction interval gives an estimated range of a future observation based on a sample. It is calculated by taking a sample of the population and using statistical methods to estimate the range in which a future observation would fall, with a certain level of confidence.

Since a prediction interval includes the uncertainty of an unobserved future value, it will typically be wider than the confidence interval estimate of the expected value of y which is based on the sample and the estimation of the population parameter.

Therefore Option A is the correct answer.

Graph B is a function because each value of x corresponds to exactly one y-value.

What is the graph of a function?

The graph of a function f is the set of all points in the plane of the form (x, f(x)). We could also define the graph of f to be the graph of the equation y = f(x). So, the graph of a function is a special case of the graph of an equation.

Using the function concept, it is found that:

Graph B is a function because each value of x corresponds to exactly one y-value.

In a function, one value of the input can be related to only one value of the output.

In a graph, it means that for each value of x(horizontal axis), there can be only one respective value of y(vertical axis).

In this problem, at Graph A, when x = 5, for example, a vertical line crosses the function 3 times, hence there are 3 respective values of y for x = 5, and the same is valid for other values of x, hence it is not a function.

In Graph B, for each value of x, there is only one value of y, hence it is a function.

Hence, Graph B is a function because each value of x corresponds to exactly one y-value.

Answer:

To find the value of the quantity after 46 years, we can use the formula for continuous compound interest:

A = P(1 + r)^t

Where:

A = final amount

P = initial amount (4400)

r = rate of growth (0.5%)

t = number of years (46)

We need to convert the percentage rate to decimal form, so we divide the rate by 100

0.5/100 = 0.005

Now we can substitute the values into the formula:

A = 4400(1 + 0.005)^46

A = 4400(1.005)^46

A = 4400 * 1.294624

A = 5685.89

Therefore, the value of the quantity after 46 years is 5685.89, to the nearest hundredth.

A parabola is a U-shaped plane curve in which every point is situated at an equal distance from both the focus, a fixed point, and the directrix, a fixed line.

The quadratic equation represents a parabolic curve on a graph

Examining the graph the function values can be deduced noting that the values 3 5 6 and in h(3), h(5) and h(6) are points in the x axis or the domain

The function to represent the arithmetic sequence is y = 0.17x + 0.71, and an envelop weighing 8 ounces cost $2.07

An equation is an expression that shows the relationship between variables and numbers.

An arithmetic sequence is in the form:

[tex]a_n=a_1+(n-1)d\\\\where\ a_1=first\ term,d=common\ difference[/tex]

Let y represent the price to send an envelop of x ounces. The arithmetic sequence is:

y = a₁ + (x - 1)d

Given that the first ounce is 88 cents($0.88), hence a₁ = 0.88. Eadh additional ounce is 17 cents (0.17), hence d = 0.17. Therefore:

y = 0.88 + (x - 1)(0.17)

y = 0.17x + 0.71

For a cost of $2.07:

2.07 = 0.17x + 0.71

x = 8 ounces

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value. Unitary method is a technique by which we find the value of a single unit from the value of multiple devices and the value of more than one unit from the value of a single unit. It is a method that we use for most of the calculations in math.

Given that the flat cost of Jim's Auto Shop is $15 dollars.

The flat cost of Danny's Wrecker Services = $10.

The per-mile cost for Jim's Auto Shop = 0.50

The per-mile cost for Danny's Wrecker Services = 0.75

Let's say that vehicle needs to be towed for x number of miles.

A percentage under the density curve is obtained by the area under the density curve that respects the given features.

The area for which x is more than 3 is composed by all the area of the density curve that is to the right of 3.

The area to the right of 3 is composed as follows:

The area of a right triangle is given by half the multiplication of the sides, hence:

At = 0.5 x 1 x 0.4 = 0.2 units squared.

The area of a rectangle is given by the multiplication of dimensions, hence:

Ar = 2 x 0.8 = 0.8 units squared.

Mathematically, the inverse is; [tex]f^{-1}(x) = \dfrac{2\cdot x + 1}{x - 1}[/tex]

The inverse of a function is another function that undoes the operations of another function, such that when the output of the function is the input of the inverse function, the input of the function is obtained.

The specified function is presented as follows;

f(x) = (x + 1)/(x - 2) and x ≠ 2

The inverse of the above function is found as follows;

Let y represent f(x);

y = (x + 1)/(x - 2)

x·y - 2·y = x + 1

x·y - x = 1 + 2·y

x·(y - 1) = 1 + 2·y

x = (1 + 2·y)/(y - 1) = (2·y + 1)/(y - 1)

Plugging in y = x, and x = f⁻¹(x), we get;

f⁻¹(x) = (2·x + 1)/(x - 1)

What is a proportion?

A proportion is an equation that states that two ratios are equal. In other words, it is a statement that says two fractions are equivalent. The most common way to write a proportion is in the form of "a/b = c/d".

We are told that Mikel gave a $1.32 tip for an order that cost $8.80. We are asked to determine whether or not each given tip is proportional to Mikel's tip.  

Let us compare our given tip and order cost proportions with Mikel given tip and order cost proportion.

1) 1.32/8.80 = 2.22/14.80

   0.15 = 0.15

We can see that our given proportion is equal to Mikel's proportion, therefore, the tip given in the first option is proportional to Mikel's tip.

2) 1.32/8.80 = 1.86/10.50

   0.15 ≠0.177

We can see that tip given in the second option is greater than Mikel's tip, therefore, it is not proportional to Mikel's tip.

3) 1.32/8.80 = 0.78/5.20

   0.15 = 0.15

We can see that our both proportions are equal, therefore, a tip given in the third option is proportional to Mikel's tip.

Hence,

1. Proportional to Mikel's tip.

2. Not proportional to Mikel's tip.

3. Proportional to Mikel's tip.

Solving a linear equation we can see that the tank will be filled in 12 minutes.

We know that the fish tank has a volume of 30 gallons, and it already has 24 gallons of wate on it.

Sara is adding more water at a rate of 0.5 gallons per minute, so after x minutes, the volume of water on the tank is modeled by the linear equation:

V(x) = 24gal + 0.5gal*x

The tank will be full when the volume is equal to 30 gallons, then we can solve the equation:

30 gal = 24 gal + 0.5gal*x

30 gal - 24gal = 0.5gal*x

6 gal = 0.5gal*x

6gal/0.5gal = x

12 = x
