Answer:
I will assume that you mean solve for q.
q < -2
Step-by-step explanation:
-2q - 2 > 2
+2 +2
Add 2 to both sides
2q > 4
/-2 /-2
Divide both sides by -2 (flip the sign if you multiply or divide by a negative number)
q < -2

what is front-end estimation
Front-end estimation is a particular way of rounding numbers to estimate sums and differences.
To use front- end estimation, add or subtract only the numbers in the greatest place value. Then add the decimals rounded to the nearest tenth.
Step-by-step explanation:
In front end estimation we are going to replace the original number with a number that is close by but only has one non zero digit. Examples: {20, 300, -50, 1,000, 80,000}. For example take the number 32, the choices to replace it with are 30 or 40 (they both have only one non-zero digit).

The US Census Bureau provides a questionnaire that asks the respondent about the number of people who live in the household, the state in which the respondent resides, and the household income. The US Census Bureau also records whether the respondent answered the census by phone, mail, or the internet. Which of the following statements is true concerning the variables recorded by the US Census Bureau in this scenario?
Four variables are measured, one of which is categorical.
Three variables are measured, one of which is categorical.
Four variables are measured, three of which are categorical.
Four variables are measured, two of which are categorical.
Three variables are measured, two of which are categorical.
Answer:
The correct option is;
Four variables are measured, two of which are categorical
Step-by-step explanation:
Categorical variables are variables with a limited number of possible values or variables that consist of two or more possible categories such that each member of the population can be assigned to a particular category in which the categories do not posses an order or preference
Quantitative variables represent numerical values of a measurement of a given quantity. Quantitative variables indicates indicates the values of a required information.
With regards to the variables recorded by the US Census Bureau in the given scenario, we have;
The categorical variables are;
1) The state in which the respondent reside
2) Weather the respondent answered the census by phone, mail, or the internet
The quantitative variables are;
1) The number of people who live in the household
2) The household income
Answer:
(D) Four variables are measured, two of which are categorical.
Step-by-step explanation:
I just took the AP Stat Unit test on Edg2022 and got 100%.
If your wondering, the two variables that are categorical are the state, and the method that the people responded.
The number of people per household and household income are quantatative.

Find two functions defined implicitly by the given relation y^2-64x^2=64
Answer: The two functions are
f(x) = sqrt(64x^2+64)
g(x) = -sqrt(64x^2+64)
Graphing these together forms a hyperbola
To get these two functions, we need to solve for y
y^2 - 64x^2 = 64
y^2 = 64x^2 + 64
y = sqrt(64x^2 + 64) or y = -sqrt(64x^2 + 64)
The last line is similar to how x^2 = 9 has two solutions (x = plus or minus 3)
Write an equation of the line that passes through the given points (-2, -6) and (1, 2).
Answer: 3y - 8x + 2 = 0
Step-by-step explanation:
The formula is
y - y₁ y₂ - y₁
------- = ---------- where x₁ = -2, x₂ = 1, y₁ = -6, y₂ = 2,
x - x₁ x₂ - x₁
Now we substitute for the values in the above equation and then solve.
y - (-6) 2 - (-6) 2 + 6 8
---------- = ----------- = --------- = ----
x - (-2) 1 - (-2) 1 + 2 3
y + 6 8
-------- = ---- , we now cross multiply to get the required equation.
x + 2 3
3( y + 6 ) = 8( x + 2 )
3y + 18 = 8x + 16
3y - 8x + 18 - 16 = 0
3y - 8x + 2 = 0
Susan has a blue skirt, a green skirt, and a gray skirt. She also has a white sweater, a purple sweater, and a green sweater. If she randomly selects her outfit, what is the probability she will select the gray skirt and the purple sweater to wear to work that day? Answer options with 5 options A. one-ninth B. one-sixth C. one-third D. two-thirds E. 2
Answer:
C
Step-by-step explanation:
Because there is 3 sweaters and three skirts. 3+3 is 6, so because you are choosing 2 out of the 6, it's 2/6. Simplify and that's 1/3.
The probability she will select the gray skirt and the purple sweater to wear to work that day is 1/9.
What is probability?
Probability is the chance of happening an event or situation.
Colors of skirt: blue, green, and gray.
Probability of choosing any skirt is = 1/3.
Colors of sweater: white, purple, and green.
Probability of choosing any sweater is = 1/3.
Now, the probability she will select the gray skirt and the purple sweater to wear to work that day is = 1/3 × 1/3 = 1/9.

Show your work and steps. If your answer is not an integer, explain what two integers your answer is between. 2. What is the mean change in the forecasted low temperatures over the next 7 days? Remember, this can be found by averaging the values in the Difference column for the low temperatures. If your answer is not an integer, explain what two integers your answer is between.
Answer:
The table is missing in the question. The table is provided below.
Step-by-step explanation:
1. In the table, it is given the difference of high temperature. They are :
-7, -7, 2, 5, -3, -2
Now adding the differences of high temperatures and taking out its average.
-7 + (-7) + 2 + 5 + (-3) + (-2)= -12
Average : [tex]$-\frac{12}{6}=-2$[/tex]
Thus the answer is an integer.
2. In the table, it is given the difference of high temperature. They are :
0, -3, -7, -1, 1, 0
Now adding the differences of high temperatures and taking out its average.
0 + (-3) + (-7 )+ (-1) + 1 + 0= -10
Average : [tex]$-\frac{10}{6} = -1.66$[/tex]
Thus, the answer is not an integer. The answer lies between the integers -2 to -1.

Step-by-step explanation:
What are the linear factors of the function f(x) = 2x^3 − 3x^2 − 2x + 3? Select each correct answer.
(x − 2)
(2x − 3)
(x − 1)
(2x + 3)
(x + 1)
(x + 2)
Edit: I ended up getting the answer the old fashioned way, working it out. The answers are (2x - 3), (x - 1), and (x + 1).
Answer:
The factors of the polynomial are (x+1), (2x-3) and (x -1)
Step-by-step explanation:
Here, we want to know the linear factors of the function.
What we simply want to calculate are those factors when multiplied with each other gives the polynomial in question.
We start by looking at the polynomial itself, we discover that the polynomial in question is a polynomial of degree three. What this means is that the polynomial will have three roots.
In this kind of question, we make use of testing.
Testing in the sense that since we know that the factor of a polynomial if substituted in that polynomial will give no remainder( 0)
So let’s say we start with one of the options (x-1)
We set this to 0
x -1 = 0
This implies that x = 1
So make a substitution of x= 1 in the polynomial
We will get;
2(1)^3 - 3(1)^2 -2(1) + 3 = 2-3-2+3 = 0
This means that (x-1) is actually a factor
The next thing to do is to use the polynomial long division; That will be;
(2x^3 − 3x^2 − 2x + 3)/ (x-1)
This gives ;
2x^2 -x -3
We can now proceed to factorize the quadratic equation;
That will be;
2x^2 + 2x -3x -3
= 2x(x + 1) -3( x + 1)
So the factors are;
(2x-3)(x+ 1)
These are the two other factors aside (x-1)

. Mount Everest is 29,028 feet above sea level. The bottom of the Mariana Trench is 36,070 feet below sea level. What is the difference between these two elevations?
The difference between these two elevations is 7024 feet.
Given,
Mount Everest is 29,028 feet above sea level.
The bottom of the Mariana Trench is 36,070 feet below sea level.
We need to find out what is the difference between these two elevations.
How do we measure the distance above and below sea level?When we measure the distance above sea level we measure it as a positive distance but when we measure the distance below the surface we measure it as a negative distance.
Find the distance of Mount Everest above sea level.
= 29.028
Find the distance of the Mariana trench below sea level.
= 36,070
Find the difference in distance between them.
We are to find the difference in distance between them not the distance between them.
So,
Mariana trench is higher than Mount Everest by:
= 36,070 - 29,028
= 7024 feet
Thus the difference between these two elevations is 7024 feet.
