what is the relationship between two variables such that when one variable doubles the other variable doubles
The relationship between two variables in which one variable doubles when the other variable doubles is called a direct proportion or direct relationship.
This means that the two variables are directly related, and their values increase or decrease in the same proportion.
In mathematical terms, this is represented by a linear equation in the form of y = kx, where y is the dependent variable, x is the independent variable, and k is the constant of proportionality.
Therefore, when x doubles, y doubles as well, and when x triples, y triples as well.

The numerator can be written as
\(f^3g^{-2}\)Second part
denorminator h raised to the power of negative 1
The numerator can be written as
\(h^{-1}\)combining part one and two
Open parentheses fraction - fraction - close parentheses to the power of 4
This gives
\((\frac{f^3g^{-2}}{h^{-1}})^4\)simplifying the expression to remove negative exponent
Simplifying the numerator
\(\begin{gathered} f^3g^{-2}=f^3\times g^{-2} \\ f^3g^{-2}=f^3\times\frac{1}{g^2} \\ f^3g^{-2}\text{ = }\frac{f^3}{g^2} \end{gathered}\)simplfying the denorminator
\(h^{-1}\text{ = }\frac{1}{h}\)combining simplfied values for numerator and denorminator in the general form we have
\(\begin{gathered} (\frac{f^3g^{-2}}{h^{-1}})^4\text{ = }(\frac{\frac{f^3}{g^2}}{\frac{1}{h}})^4 \\ (\frac{f^3g^{-2}}{h^{-1}})^4=\text{ (}\frac{f^3}{g^2}\times h)^4\text{ } \\ (\frac{f^3g^{-2}}{h^{-1}})^4\text{ = (}\frac{f^3h}{g^2})^4 \end{gathered}\)Hence, the simplified form of the expression is

A. 66
B. B
C. A1
D. Illegal expression
Unicode value of 66, which is the letter "B". Therefore, the correct answer to this question is option B: "B".
The terms you mentioned are related to the Unicode character encoding standard and the concept of evaluating expressions. When discussing the expression "A" + 1, it's essential to note that the Unicode value for the character "A" is 65.
The expression "A" + 1 is attempting to add a numerical value (1) to a character ("A"). In many programming languages, this operation is allowed, and the result would be based on the Unicode values of the characters involved. Since the Unicode value for "A" is 65, adding 1 to it would result in a new Unicode value of 66. Consequently, the evaluated expression would correspond to the character with the Unicode value of 66, which is the letter "B". Therefore, the correct answer to this question is option B: "B".

If Z is a standard normal random variable, the area between z = 0.0 and z =1.30 is 0.4032, while the area between z = 0.0 and z = 1.50 is 0.4332. What is the area between z = -1.30 and z = 1.50?
A. 0.0668 B. 0.0968 C. 0.0300
D. 0.8364
The area between z = -1.30 and z = 1.50 is B. 0.0968.
To get the area between z = -1.30 and z = 1.50, we need to subtract the area to the left of z = -1.30 from the area to the left of z = 1.50.
The area to the left of z = -1.30 is the same as the area to the right of z = 1.30, which is 1 - 0.4032 = 0.5968.
The area to the left of z = 1.50 is 0.4332.
Therefore, the area between z = -1.30 and z = 1.50 is 0.4332 - 0.5968 = 0.0968.
So the answer is B. 0.0968.

Describe the similarities and differences between finding the slope of a linear equation from a graph that has x and y scales that are 1:1, and from a graph that has x and y scales that are not 1:1 (say your x and y scales are 2, 4, 6).
Using the concept of the slope of a linear function, we have that:
For a graph in a 1:1 scale, we can look at two consecutive values, y when x = a and y* when x = a + 1, and subtract y* by y. For a graph in another scale, we also do the same thing, but since the scale is not 1:1, we have to divide the subtraction of y* by y by the scale.What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.Given two points in the graph of a function, the slope is given by change in y divided by change in x, hence:
For a graph in a 1:1 scale, we can look at two consecutive values, y when x = a and y* when x = a + 1, and subtract y* by y. For a graph in another scale, we also do the same thing, but since the scale is not 1:1, we have to divide the subtraction of y* by y by the scale.More can be learned about linear function concepts at https://brainly.com/question/24808124

what topic is used when discussing the need for relative figures as opposed to absolute figures?
The topic that is typically discussed when referring to the need for relative figures as opposed to absolute figures is comparative analysis or relative measures.
Comparative analysis involves comparing data or figures in relation to other data or a reference point, rather than focusing solely on the absolute values. It helps provide context and a better understanding of the data by considering factors such as proportions, ratios, percentages, or changes over time. Relative figures are particularly important when dealing with data that varies significantly in scale or when comparing data across different contexts or populations. By using relative figures, researchers or analysts can gain insights into patterns, trends, and relationships that may not be evident when looking at absolute figures alone.

Mariah is training for the marathon. Today she ran 12 miles for 1 hour and 30 minutes . If the relationship between her distance covered and the number of minutes is proportional, write an equation that Mariah can use to represent the proportional relationship between her distance ( d ) and her time ( t).
Answer:
d= 8 t
Step-by-step explanation:
In 1 hour 30 minutes it ran for 12 miles.
So, time t =1.5 hours(Because 1 hour 30 minutes)
distance d =12
We know distance d= rate 'r' * time 't'.
So, using given information , find the rate
12= r *1.5
Divide both sides by 1.5
8=r
So, equation would be d =8 t.
Where 't' is in hours.
evaluate the indefinite integral. (use c for the constant of integration.) ∫ √x^11 sin(3 x^13/2) dx
The indefinite integral of √\(x^{11\) × sin(3\(x^{(13/2)\)) dx is -2/39 × cos(3\(x^{(13/2)\)) + C, where C represents the constant of integration.
To evaluate the indefinite integral of √\(x^{11\) × sin(3\(x^{(13/2)\)) dx, we can use substitution. Let's substitute u = \(x^{(13/2)\):
Step 1: Find du/dx:
Differentiating both sides with respect to x:
du/dx = (13/2) × \(x^{(11/2)\)
Step 2: Solve for dx:
Rearrange the equation to solve for dx:
dx = (2/13) × du / \(x^{(11/2)\)
Step 3: Substitute the values in the integral:
∫ √\(x^{11\) × sin(3\(x^{(13/2)\)) dx = ∫ √\(x^{11\) × sin(3u) × (2/13) × du / \(x^{(11/2)\)
Step 4: Simplify the integral:
∫ √\(x^{11\) × sin(3\(x^{(13/2)\)) dx = (2/13) × ∫ sin(3u) du
Step 5: Integrate with respect to u:
∫ sin(3u) du = - (1/3) × cos(3u) + C,
where C is the constant of integration.
Step 6: Substitute back the value of u:
∫ √\(x^{11\) × sin(3\(x^{(13/2)\)) dx = (2/13) × (-1/3) × cos(3u) + C
= -2/39 × cos(3\(x^{(13/2)\)) + C.

The number of elements in the sample space for this experiment is 969.
If a person eating at a cafeteria must choose 3 of 19 vegetables on offer, we can calculate the number of elements in the sample space, or the total number of possible outcomes, using the formula for combinations:
nCr = n! / [r!(n - r)!]
where n is the total number of items in the set and r is the number of items being chosen.
In this case, we have 19 vegetables and we want to choose 3 of them, so we can plug in n = 19 and r = 3:
19C3 = 19! / [3!(19 - 3)!]
= 19! / (3!)(16!)
= 969
Therefore, there are 969 possible combinations of 3 vegetables that a person can choose from a selection of 19 vegetables.

What is a residual for a multiple regression model and the data that is used to create it? select one.
The difference between the actual value of the response variable and the corresponding predicted value(regression error) using the multiple regression model is the correct option.
A residual is a measurement of the vertical distance between a point and the regression line. It is just the discrepancy between an actual value observed and a value that was projected.
To ensure that the requirements for making conclusions about the coefficients in a linear model have been met, one should always perform a residual analysis.
In regression analysis, a residual is the discrepancy between an observed value and a predicted value.
It is determined by,
Residual = Observed value – Predicted value
The residual is the discrepancy between the expected value and the actual value.
