The level of measurement that is appropriate for a classification where students are asked to rank their professors as good, average, or poor is the ordinal level of measurement.

Ordinal level of measurement is a statistical measurement level.

It involves dividing data into ordered categories.

For instance, when asked to rank teachers as good, average, or poor, the students' rating of the teachers falls under the ordinal level of measurement.

The fundamental characteristic of ordinal data is that it can be sorted in an increasing or decreasing order.

The numerical values of the categories are not comparable; instead, the categories are arranged in a specific order.

The ordinal level of measurement, for example, provides the order of the data but not the size of the intervals between the ordered values or categories.

\(\cfrac{89.40~~ - ~~\stackrel{ \textit{minus the tax of each} }{0.50-0.50-0.50-0.50-0.50-0.50}}{6}\implies \cfrac{86.40}{6}\implies \stackrel{ each }{14.40}\)

Step-by-step explanation:

could it be that the equation is rather

-5 = (-8 + v)/3

?

that is a huge difference ...

to solve such an equation we keep transforming it (every change we make we have to do on both sides of the equation to keep the equality), until we have only the variable on one side, and everything else (which is then the solution) on the other side.

1st step : we get rid of the "/3" by multiplying both sides by 3.

that gives us

-5×3 = ((-8 + v)/3)×3 via the multiplication property.

2nd step : we simplify

-15 = -8 + v

3rd step : we get rid of the -8 on the side of the variable by adding 8 to both sides.

that gives us

-15 + 8 = -8 + 8 + v via the addition property.

4th step : we combine like terms (or simplify, if we can use it a second time) :

-7 = 0 + v

-7 = v

that's it.

The shape of the probability distribution for the random walk problem depends on the values of p and q. When p = q, the distribution is symmetric, while if p and q have different values, the distribution becomes asymmetric.

The shape of the probability distribution for the problem of the random walk can be determined by considering the values of p and q, where p represents the probability of moving in one direction and q represents the probability of moving in the opposite direction.
(a) In this case, we are given that p = q = 1/2, which means that there is an equal probability of moving in either direction.
When p = q = 1/2, the probability distribution for the random walk problem will have a symmetric shape. This means that the probabilities of moving to the left and the right are the same. For example, if we start at position 0 and take 20 steps, the probability of ending up at position +10 will be the same as the probability of ending up at position -10.
It is important to note that the specific values of p and q do not affect the shape of the distribution. As long as p = q, the distribution will be symmetric.

(b) Now, let's consider a different scenario where p = 0.6 and q = 0.4. In this case, the probability of moving in one direction is greater than the probability of moving in the opposite direction. This will result in an asymmetric probability distribution.
For example, if we start at position 0 and take 20 steps, the probability of ending up in a positive position will be higher than the probability of ending up in a negative position. The distribution will be skewed towards the positive position.

Answer:

C) g(x) = f(x) + 4

Step-by-step explanation:

A vertical shift is where you shift, slide or translate the whole graph up or down (on a graph) The way this shows up in the equation is just a number tacked on to the end of the equation. A +anumber (like the +4 in the answer) slides the function UP four units. A

-anumber would slide the function DOWN instead.

As for the other answers:

A) the 3multiplied in front is a vertical STRETCH.

D) the 1/2 multiplied in front is a vertical shrink (smash)

B) The -3 in close tight with the x is a horizontal shift(slide, translate) It is a RIGHT shift. A +anumber would be a LEFT shift. Horizontal shift seem kind of backwards. + goes LEFT and - goes RIGHT.

Answer:

Dimensions:  125 m x 250 m

Area:  31,250 m²

Step-by-step explanation:

Given information:

First, let us assume that the land is rectangular in shape.

Let \(y\) = length of the side opposite the river

Let \(x\) = length of the other 2 sides of the land

Therefore, we can create two equations from the given information:

  Area of land:   \(A= xy\)

  Perimeter of fence:   \(2x + y = 500\)

Rearrange the equation for the perimeter of the fence to make y the subject:

\(\begin{aligned} \implies 2x + y & = 500\\ y & = 500-2x \end{aligned}\)

Substitute this into the equation for Area:

\(\begin{aligned}\implies A & = xy\\& = x(500-2x)\\& = 500x-2x^2 \end{aligned}\)

To find the value of x that will make the area a maximum, differentiate A with respect to x:

\(\begin{aligned}A & =500x-2x^2\\\implies \dfrac{dA}{dx}& =500-4x\end{aligned}\)

Set it to zero and solve for x:

\(\begin{aligned}\dfrac{dA}{dx} & =0\\ \implies 500-4x & =0 \\ x & = 125 \end{aligned}\)

Substitute the found value of x into the original equation for the perimeter and solve for y:

\(\begin{aligned}2x + y & = 500\\\implies 2(125)+y & = 500\\250+y & = 500\\y & = 250\end{aligned}\)

Therefore, the dimensions that will give Christine the maximum area are:

125 m x 250 m (where 250 m is the side opposite the river)

The maximum area is:

\(\begin{aligned}\implies \sf Area_{max} & = xy\\& = 125 \cdot 250\\& = 31250\: \sf m^2 \end{aligned}\)

The amount of money in the account after adding simple interest of 7% rate  is respectively $17.5, $52.5,  $122.5,  $350

Simple interest is a amount which is calculated for a certain period of time and for a certain rate, in simple interest calculation there are three factors which we consider principle amount(P), rate(R) and time(T).

Every time we calculate simple interest the principle values will be same unlike compound interest.

Formula;    Simple Interest(I) =  P × R × T/100

Given that,

P = $250

R =  7%

For T =  1 year

I  =   250 × 7 × 1/100

  =   $17.5

For T =  3 year

I  =   250 × 7 × 3/100

  =   $52.5

For T =  7 year

I  =   250 × 7 × 7/100

  =   $122.5

For T =  20 year

I  =   250 × 7 × 20/100

Answer: answer is 59 F

Step-by-step explanation:

The probability that a basketball player with a 71% free throw shooting accuracy does not make his next free throw shot is 29%.

The probability that a basketball player with a 71% free throw shooting accuracy does not make his next free throw shot.
To calculate the probability of missing a free throw shot, we need to subtract the shooting accuracy percentage from 100%.

In this case, the probability of making a free throw is 71%, which means the probability of missing the free throw is 29%.

Therefore, the probability that the basketball player does not make his next free throw shot is 29%.
It is important to note that free throw shooting accuracy can vary depending on the player's physical and mental condition, as well as external factors such as the audience's noise, the game's pressure, and the distance from the basket.

Thus, it is crucial for basketball players to train and practice regularly to improve their shooting skills and increase their chances of making free throw shots.
To answer this, we need to consider the complement of the success probability.

Since the player has a 71% chance of making the free throw, it means there is a 29% chance that he will not make it (100% - 71% = 29%).

The probability can also be expressed as a decimal, which is 0.29 (29/100 = 0.29).

Therefore, the probability that your favorite basketball player does not make his next free throw shot is 29% or 0.29.

The area of the walk is 312 square feet.

To find the area of the walk, we first need to find the dimensions of the inner rectangle formed by the walk.

The original rectangular yard measures 31ft by 51ft. The walk along the fence is 2ft wide on each side. This means that the inner rectangle will have dimensions 31ft - 2ft - 2ft = 27ft by 51ft - 2ft - 2ft = 47ft.

The area of the walk is then calculated as the difference between the area of the outer rectangle (31ft by 51ft) and the area of the inner rectangle (27ft by 47ft).

Area of the walk = Area of the outer rectangle - Area of the inner rectangle

= (31ft * 51ft) - (27ft * 47ft)

= 1581ft² - 1269ft²

= 312ft²

Therefore, the area of the walk is 312 square feet.

Therefore, Ciera is driving faster.

The value of x that makes the equation true is x = 9.

To solve the equation 12/X = 8/6 we can cross-multiply to eliminate the fractions.

By multiplying both sides of the equation by x, we get: 12= 8/6 x

Simplifying the right side of the equation, we have: 12= 4/3 x

To isolate x, we can multiply both sides of the equation by 3/4

3/4 × 12 = 3/4 × 4/3 × x

The 4 and 3 cancel out on the right side, resulting in: 9=x.

Therefore, the value of x that makes the equation true is x=9.
