Answer:
Nominal variables.
Step-by-step explanation:
In Mathematics, a random variable can be defined as any variable whose values are determined by the outcome of a random experiment.
Basically, random variables are classified into two (2) main categories and these are;
1. Discrete variable: a discrete variable is a data set in which the number of possible values are either finite or countable. For instance, the value of a fair die, number of sweets in a jar, number of eggs in a crate etc.
2. Continuous variable: a continuous variable is a data set having infinitely many possible values and those values cannot be counted, meaning they are uncountable. Any quantity such as height, volume, weight, density, length, pressure, temperature, speed, distance, time are generally a continuous random variable.
Hence, the other name for continuous variables is nominal variables because they are numerical in nature.
What is the result of 8(x - y)? The value for x is -5 and y is -2
Answer:
8(-5 - -2) = 24. Inside the parantheses is 3. Then you'd multiply 8, which is 24
Step-by-step explanation:
Answer:

Answer:
C
Step-by-step explanation:
Graph C is a function because if you look at all of the graphs it is the only one that doesn't repeat a point on the same x-axis. For example, On the first graph, it shows that A has to points that has a coordinate of -2, and the rest show that too, except for C.

Step-by-step explanation:
The lines represent the lines of symmetry where the image can be reflected upon. Hence it is reflectional.
The dot in the middle of the image tells us that the image can be rotated about the dot to produce the exact same image. Hence it is rotational.
The answer is both rotational and reflectional.
Answer:
I broke it to phrases. Make sure to read both.
It is rotational symmetry. This is because rotational symmetry means it is able to be rotated, and looks the same. This is true with this figure. The lines demonstrate that it is an equal dimensioned 2D shape.
It is ALSO reflection symmetry because this means it can be split through the center and looks exactly the same, as if it was a reflection. This is true here too because it has the same amount of lines split through the same angle on each side making it equal. You can also see a line already going through the shape, and as you can see if you look at see side it looks equal, like a reflection.
The answer is D.

What should managers use if they want to identify and respond in a timely manner to social and political shifts?
Answer:
They need to use issues management
Step-by-step explanation:
Due to the fact that social and political shifts are usually quite complex in terms of the possible issues that arise from them, managers are best served to use Issues management because it is an anticipatory and strategic management process which aids organizations in quick & timely detection and response to changes in the socio - political system or environment.

Nancy has 7 boxes of tomatoes. Each day, she picks another
2
box. How many boxes of
tomatoes will Nancy have in 6 days? Write an equation, complete the table, and then graph to
solve the problem.
Answer:
19 boxes of tomatoes
Step-by-step explanation:
If she starts with 7 boxes of tomatoes and she picks 2 more each day for 6 days then you can multiply 2 by 6 and get 12 tomatoes then you add the 7 boxes she originally started with and you get 19 boxes of tomatoes.
The number of boxes Nancy had after 6 days is 19, the equation representing the given phrase is y = 2x + 7, and the graph is attached below.
What is graph?A collection of objects is arranged in a graph, where some object pairings are conceptually "linked." Each pair of connected vertices is referred to as an edge, and the objects are represented by mathematical abstractions known as vertices.
Given:
Nancy has 7 boxes of tomatoes,
Each day, she picks another 2 boxes,
The equation which will represent the above phrase is shown below,
Total number of tomatoes = The number of tomatoes she already had + number of days × each day's tomatoes picked by Nancy,
Assume the total number is y and the number of days is x then,
y = 7 + 2 × x
y = 2x + 7
Put the value of x = 6,
y = 2 × 6 + 7
y = 12 + 7
y = 19
Thus, she has a total of 19 boxes of tomatoes after 6 days.

Answer and Step-by-step explanation:
First off, write the equation in slope intercept form.
y = [tex]-\frac{2}{3} x + 2[/tex]
(3, 0) is the x intercept, so when we go up 2 and left 3 (opposite of the slope, since we want to find the y-intercept), we get a y-intercept of 2.
Now, you put this equation into point-slope form.
Subtract 2 from both sides of the equation.
[tex]y - 2 = -\frac{2}{3} x[/tex]
2 represents [tex]y_{1}[/tex], and the 0 will represent [tex]x_{1}[/tex]. This is because when you plug in 0 for x, you get 2 as the result.
So, the equation should be:
[tex]y - 2 = -\frac{2}{3} (x + 0)[/tex]

Is there a proportional relationship between number of sandwiches and the cost of the order? Explain how you know.
(The picture shows what the relationship is now all I need to find is if it’s proportional or not, and why. Can you help me please? It’s homework, and it’s due in 5 minutes.)
Answer:
No, there is no proportional relationshipStep-by-step explanation:
The proportional relationship is:
y = kx, which is a special form of linear equation, with zero y-interceptIn the given case we have:
y = 4.5x + 10This is a linear function but not proportional relationship because it has y-intercept, different than zero
What is the inverse of the function f(x) = 4x + 8?
Answer:
h(x) = (1/4)x - 2 which is choice A
Step-by-step explanation:
Replace f(x) with y. Then swap x and y. Lastly, solve for y to get the inverse.
f(x) = 4x+8
y = 4x+8
x = 4y+8
x-8 = 4y
4y = x-8
y = (x-8)/4
y = x/4 - 8/4
y = (1/4)x - 2
h(x) = (1/4)x - 2

Amy has 20 necklaces in a jewelry box. The probability of reaching into the jewelry box and pulling out a silver necklace is 0.85. What is the probability that Amy will reach in the jewelry box and pull out a necklace that is not silver?
Answer:
0.15
Step-by-step explanation:
Given
[tex]Necklaces = 20[/tex]
Represent the probability of pulling out silver with p; So:
[tex]p = 0.85[/tex]
Required
Determine the probability of not pulling silver
This question is to test probability complements
And the complement rule of probability states that:
[tex]p + q = 1[/tex]
Where q and p are opposites. In other words:
q = probability of not pulling out silver
Substitute 0.85 for p in [tex]p + q = 1[/tex]
[tex]0.85 + q = 1[/tex]
Make q the subject
[tex]q = 1 - 0.85[/tex]
[tex]q = 0.15[/tex]
Hence, the required probability is 0.15

In a class in which the final course grade depends entirely on the average of four equally weighted 100-point tests, Paul has scored 75, 80, and 91 on the first three. What range of scores on the fourth test will give Paul a C for the semester (an average between 70 and 79, inclusive)? Assume that all test scores have a non-negative value.
Answer:
Scores between 34 and 70 on the fourth test will give Paul a C for the semester.
Step-by-step explanation:
The average is given by the sum of all scores divided by the number of scores.
In this question:
Sum of all scores: 75 + 80 + 91 + x = 246 + x
Number of tests : 4
Grade of 70:
[tex]\frac{246 + x}{4} = 70[/tex]
[tex]246 + x = 280[/tex]
[tex]x = 280 - 246[/tex]
[tex]x = 34[/tex]
Grade of 79:
[tex]\frac{246 + x}{4} = 79[/tex]
[tex]246 + x = 316[/tex]
[tex]x = 316 - 246[/tex]
[tex]x = 70[/tex]
Scores between 34 and 70 on the fourth test will give Paul a C for the semester.
