The mean of the sampling distribution is related to the mean of the population, the standard deviation of the sampling distribution is related to the standard deviation of the population and the shape of the sampling distribution is affected by the sample size.

a. The mean of the sampling distribution is related to the mean of the population. The mean of the sampling distribution is an estimate of the population mean and is usually denoted by x⁻. The mean of the sampling distribution is expected to be close to the population mean, as the sample size increases. However, if the sample size is small, there will be more variation in the sample means and the sample mean will not be an accurate estimate of the population mean.

b. The standard deviation of the sampling distribution is related to the standard deviation of the population. The standard deviation of the sampling distribution is an estimate of the population standard deviation and is usually denoted by s. The standard deviation of the sampling distribution is expected to be smaller than the population standard deviation, as the sample size increases. The standard deviation of the sampling distribution is also affected by the sample size, it decreases as sample size increases.

c. The shape of the sampling distribution is affected by the sample size. As the sample size increases, the shape of the sampling distribution becomes more normal and less skewed, regardless of the shape of the population. The larger the sample size, the less spread in the sample means and more likely that the sample mean will be close to the population mean.

To evaluate f(-x) when f(x) = x/(x^2 + 1), we need to substitute -x for x in the function.

So f(-x) = (-x)/((-x)^2 + 1)

Simplifying the denominator we get:

f(-x) = (-x)/(x^2 + 1)

The function f(-x) is equivalent to the function f(x) with the x-value negated. The value of the function f(-x) is the same as the value of the function f(x) but with the x-value negated.

It's important to note that we can also express this as f(-x) = -f(x)

So the value of f(-x) is x/(x^2 + 1) with the x-value negated.

The appropriate interval width for a random sample of 110 observations.

a) w=1

b) w=2

c) w=2

The interval width is a value that is used to divide the usage distribution into usage rate intervals.

we shall determine an appropriate interval width for a random sample of 110 observations that fall between and include each of the following.

let's start.

we are aware the formula to calculate class width.

[tex]w=\frac{L.O-S.O}{N.C}[/tex],

where,

w for width, L.O is stand for largest observation and S.O for smallest observation and N.C is number of classes.

We solve it by options.

so first come on option (a)

given interval is 20 to 85.

[tex]w=\frac{85-20}{110} \\w=\frac{65}{110} \\w=0.59[/tex]

The equation in the form y = a(x-r)(x-s) to represent the parabola is d. y = -4(x-2)(x-2).

What is the parabola?

The parabola is a smooth curve without any sharp points. It has a minimum value of a turning point called the vertex. As we can see the minimum value of this parabola is at zero, zero. That is this parabola exists only above the origin. The parabola is symmetrical about a central line called the axis of symmetry.

To represent the parabola shown in the form y = a(x-r)(x-s), we need to first identify the vertex and the axis of symmetry of the parabola.

The vertex of the parabola is (4,-4) and the axis of symmetry is x = 4.

Given that the vertex form of the parabola is y = a(x-h)² + k where (h,k) is the vertex.

Therefore, substituting the values we get:

y = a(x-4)² -4

Now, we need to find the value of a which will give us the same parabola.

If we look at the parabola, we can see that the y-coordinate of the vertex is -4 and the x-coordinate is 4.

So we substitute these values into the equation to get:

-4 = a(4-4)² -4

Solving this equation gives us a = -1

So the equation that represents the parabola is:

y = -1(x-4)² -4

which is the same as y = -1(x-4)(x-4)

thus the correct answer is d. y=-4(x-2)(x-2)

Hence, The equation in the form y = a(x-r)(x-s) to represent the parabola is d. y = -4(x-2)(x-2).

Step-by-step explanation:

Katie  after 1 hour of driving, he had 6.75 gallons of gas. Also, after 6 hours of driving, she had 1.5 gallons left.

We can write these values as coordinate points, on the form:

As a result, the sentence: "After an hour of driving, Katie had $6.75 worth of gas." can be seen as the following:

(1,6.75)

And: "After 6 hours of driving, there was only 1.5 gallons left" will have the point:

(6,1.5)$

Part B

With this in mind, we can find the slope of a linear function that passes through those two points. Then,

[tex]$m=\frac{y_2-y_1}{x_2-x_1}=\frac{1.5-6.75}{6-1}=\frac{-5.25}{5}=-1.05$[/tex]

Thus, the slope is -1.05.

Part C

Now, we will write a linear equation that relates[tex]$\mathrm{g}$[/tex] and[tex]$\mathrm{h}$[/tex]. As we already have the slope, we can use it to find the y-intercept as:

[tex]$$y=m x+b$$[/tex]

[tex]$g=m h+b$[/tex]Writing it with the variable[tex]s $\mathrm{g}$[/tex]and [tex]$\mathrm{h}$[/tex].

[tex]$$1.5=(-1.05)(6)+b$$[/tex]

[tex]1.5+6.3=b \\[/tex]

7.8=b

This means that an equation for g in terms of h is given by:

[tex]$$g=-1.05 h+7.8$$[/tex]

Part D

For this portion, we will apply the linear equation we discovered for calculating how much gas she will still have after a three-hour drive. Thus, h will have a value of 3, and we replace on the function to get the following result:

[tex]g=-1.05(3)+7.8 \\[/tex]

=-3.15+7.8

=4.65

This means that Katie will have 4.65 gallons left after driving for 3 hours.

The complete question is,

Katie noticed that after 1 hour of driving, she had 6.75 gallons of gas. After 6 hours of driving, there was only 1.5 gallons left. (Hint: Leave your answers as decimals). A.) Represent the information as two coordinate pairs in the form of (h, g), where h is the number of hours driven and g is the gallon of gas left. B.) Calculate the slope between the two coordinates.

The right response is E. n = 100 at whatever degree of confidence.

We are aware that the sample size's square root and the margin of error are inversely proportional. The margin of error therefore decreases as n increases, but we also know that margin of error is proportional to the critical value, which increases as confidence level increases. However, for t and z, and for a relevant confidence level, the critical value lies between 1-3, so the sample size has the greatest impact.Because of this, choice E is the right one.

It can be written as c² = a²+ b², where c is the hypotenuse and a,b are the other two sides.

Since the given triangle is a right anlgled triangle so we will use Pythagorean theorem:

using Pythagorean theorem :

H² = P² + B²

where H is hypotenuse , P is perpendicular and B is base of the triangle

H = 13

P = 12

B = x

To calculate the price difference between the front row and second row tickets, Jim should first identify the mean price of the second row tickets, P2. He can then compare the mean price of the second row tickets to the mean price of the front row tickets, P1. He can then calculate the price difference between the two rows by subtracting the mean price of the second row tickets from the mean price of the first row tickets, (P1-P2). This will give him the price difference, which can then be used to determine the extra he can charge for the front row tickets.

For example, if the mean price of the second row tickets, P2, is $15 and the mean price of the first row tickets, P1, is $20, then the price difference would be $5, meaning he can charge an extra $5 for the front row tickets.

Both the addition rule and the multiplication/division rule are introduced to us in algebra 1 as the two rules for solving equations. According to the equation addition rule, an equation's solution set can be changed by adding the same amount to either side of an equation without doing so.

Identification, prioritisation, and selection of potential solutions are all steps in the process of problem solving, which also involves characterising the issue at hand, figuring out its root cause, and putting a plan of action into action. Algebraic Golden Rule: "Do unto one side of the equal sign as you will unto the other."

Answer:

Step-by-step explanation:

I'm sorry, I am missing more information to calculate the speed of the car at t = 10 seconds, t = 20 and t = 30. The speed of the car depends on the mathematical function that describes the position of the car in time. Without the knowledge of that function, I'm not able to determine the car's speed at different points in time.
