The best discrete variable of measurement for the situation is an interval.

Finding the scale of measurement for the variables is the next step in selecting a statistical test after identifying the independent and dependent variables. The dependent variable must be measured using an interval or ratio scale for each of the parametric tests that we have covered so far. Many psychologists also subject variables with roughly interval scales of measurement to parametric tests. You must decide whether to use "scale" or "interval" scores when performing parametric tests of means.

Given the condition about whether the race of the defendant has an impact on jury verdicts,

and measure on a 1 (not at all) to 7 (very) scale how guilty the defendant,

The best scale of measurement for the condition is an interval.

Although the interval scale has characteristics of nominal and ordered data, it also allows for the quantification of data point differences. The variables' actual positions in the order as well as their differences are both displayed by this form of data. They can be combined or split, but not added to or subtracted from. 

The fact that zero is an existing variable adds another characteristic to this scale. Zero in the ordinal scale indicates that there is no data.

Hence the scale of measurement is an interval.

The gas used and miles are proportional for each scooter.

Proportional relationships are relationships between two variables where their ratios are equivalent.

A proportional relationship is one in which two quantities vary directly with each other. We say the variable y varies directly as x if:  

y = k x

for some constant k , called the constant of proportionality .

Therefore, let's check whether the scooter A and scooter B shows proportional relationships.

Hence,

For scooter A:

y = kx

where

Therefore,

2 = 150 k

k = 2  /150

k = 1 / 75

Hence,

y = 1 / 75 x

From the table of scooter A, the ratio is constant, therefore, the relationships of gas used and distance covered is proportional for scooter A.

For the Scooter B the graph is also proportional because the ratios of the variables are constant.

There is no curve that describes the level curve of value c for the given surface, as the condition c < 0 makes it impossible to find a real solution.

In two- or three-dimensional space, a curve is a mathematical object that symbolises a continuous, smooth path. Curves can be derived from geometric operations, parametric equations, or mathematical equations. They are commonly used to simulate real-world processes in physics, engineering, mathematics, and many other disciplines.

To find the level curve of value c for the given surface \(z = f(x, y) = (x^2/4) + (y^2/25) = c\), where c < 0, follow these steps:

Step 1: Write down the equation of the surface.
\(z = f(x, y) = (x^2/4) + (y^2/25)\)

Step 2: Replace z with the constant c.
\(c = (x^2/4) + (y^2/25)\)

Step 3: Rearrange the equation to isolate \(y^2\).
\(y^2 = 25(c - (x^2/4))\)

However, note that we're given that c < 0. This means that the value inside the parentheses (c - (\(x^2/4\))) must also be negative. Since y^2 can't be negative, there's no real solution for this equation.

In conclusion, there is no curve that describes the level curve of value c for the given surface, as the condition c < 0 makes it impossible to find a real solution.

The value of x is equal to 15°

In Mathematics and Geometry, the sum of the exterior angles of both a regular and irregular polygon is always equal to 360 degrees.

Note: The given geometric figure (regular polygon) represents a pentagon and it has 5 sides.

By substituting the given parameters, we have the following:

3x + 4x + 8 + 5x + 5 + 6x - 1 + 5x + 3 = 360°.

3x + 4x + 5x + 6x + 5x + 8 + 5 - 1 + 3 = 360°.

23x + 15 = 360°.

23x = 360 - 15

23x = 345

x = 345/23

A list of steps, in order, that will solve the following equation include the following:

In order to create a list of steps and determine the solution to the equation, we would have to add 5 to both sides and divide both sides by 2 in order to open the parenthesis as follows;

2(x + 3) – 5 = 123

2(x + 3) – 5 + 5 = 123 + 5

2(x + 3) = 128

By dividing both sides of the equation by 2, we have the following:

2(x + 3)/2 = 128/2

x + 3 = 64

By subtracting 3 from both sides of the equation, we have the following:

x + 3 - 3 = 64 - 3

x = 61

Answer:

a. y = 3x² + 9x +6

d. y = x(3x + 10)

Step-by-step explanation:

Most equations that have a squared variable are going to be nonlinear.

If you distribute the x in the d equation you get this: y = 3x² + 10x

Choices b, c, and e are going to be linear because there is only one variable, and those variables do not have exponents.

The component form of vector a⃗, rounded to the nearest hundredth, is:

a⃗ = 〈-12.99, 19.97〉

To find the component form of vector a⃗, which is expressed in magnitude and direction form as a⃗ =〈26√,140°〉, we can use the formulas for converting polar coordinates to rectangular coordinates:

x = r * cos(θ)
y = r * sin(θ)

In this case, r (magnitude) is equal to 26√ and θ (direction) is equal to 140°. Let's calculate the x and y components:

x = 26√ * cos(140°)
y = 26√ * sin(140°)

Note that we need to convert the angle from degrees to radians before performing the calculations:

140° * (π / 180) ≈ 2.4435 radians

Now, let's plug in the values:

x ≈ 26√ * cos(2.4435) ≈ -12.99
y ≈ 26√ * sin(2.4435) ≈ 19.97

Therefore, the component form of vector a⃗ is:

a⃗ = 〈-12.99, 19.97〉

The pairs of angles formed when a transversal crosses two parallel lines are categorized into four types:

1. Corresponding angles: Corresponding angles are marked with an "f" shape. They are located in matching corners when a transversal intersects two parallel lines. The key property of corresponding angles is that their measures are equal.

2. Alternate interior angles: Marked with a "Z" shape, alternate interior angles are interior angles that lie on opposite sides of the transversal and between the parallel lines. They have equal measures, making them congruent to each other.

3. Alternate exterior angles: Alternate exterior angles are marked with a "U" shape. These angles are located on opposite sides of the transversal but outside the parallel lines. Similar to alternate interior angles, alternate exterior angles have equal measures.

4. Same-side interior angles: Same-side interior angles are marked with a "C" shape. These angles are located on the same side of the transversal and between the parallel lines. The key characteristic of same-side interior angles is that they are supplementary, meaning their measures add up to 180 degrees.

The corresponding angles have equal measures, alternate interior and exterior angles are congruent, and same-side interior angles are supplementary.

Option (d) is the closest to the correct form of the particular solution.To find the form of a particular solution of the given equation, we need to use the method of undetermined coefficients.

Since r1 - 31 is a root of the characteristic equation, we can assume that the particular solution has the form:
y_p = (Ae^(r1x))(Bcos(x) + Csin(x)) + Dsin(x)

where A, B, C, and D are constants to be determined.

We differentiate y_p to get:

y_p' = Ar1e^(r1x)(Bcos(x) + Csin(x)) + Ae^(r1x)(-Bsin(x) + Ccos(x)) + Dcos(x)

y_p'' = Ar1^2e^(r1x)(Bcos(x) + Csin(x)) + 2Ar1e^(r1x)(-Bsin(x) + Ccos(x)) + Ae^(r1x)(-Bcos(x) - Csin(x)) - Dsin(x)

Substituting y_p, y_p', and y_p'' into the given equation, we get:

13Ar1^2e^(r1x)(Bcos(x) + Csin(x)) + 2Ar1e^(r1x)(-Bsin(x) + Ccos(x)) - Ae^(r1x)(Bcos(x) + Csin(x)) + 36(Ae^(r1x))(Bcos(x) + Csin(x)) - 36Dsin(x) = 22* + sin(x) + 5

Simplifying and equating coefficients of like terms, we get:

13Ar1^2B + 2Ar1C - AB + 36AB = 5    (coefficients of cos(x))
13Ar1^2C - 2Ar1B - AC + 36AC = 22* + 1  (coefficients of sin(x))
-13Ar1^2A + 2Ar1B - Ae^(r1x)B + Ae^(r1x)C = 0    (coefficients of e^(r1x))
-36D = 5   (coefficients of sin(x))

Solving for A, B, C, and D, we get:

A = 0
B = 5/(13r1^2 + 36)
C = (22* + 1 - 2Ar1B - 13Ar1^2C)/(2Ar1 - AC + 36C)
D = -5/36

Therefore, the form of the particular solution is: y_p = (5/(13r1^2 + 36))(Bcos(x) + Csin(x)) - (5/36)sin(x)

where B and C are determined as shown above.

Explanation:

The flat horizontal portion S is where the distance (y) does not increase or decrease. So Ted is stationary during this time frame.

In terms of speed, we would say speed = distance/time = (change in y)/(change in x). Note how this is the slope.

Rise = 0 because the horizontal line does not go up or down. The run is any positive number, though convention usually has Run = 1. Therefore, slope = rise/run = 0/1 = 0. All flat horizontal lines have a slope of 0 to indicate no upward or downward movement.
