Answer:
C convenience
Step-by-step explanation:
Convenience sampling (also known as availability sampling) is a type of non-probability sampling method in which data is collected from population members who are readily available for survey. An example for convenience sampling is the use of questionnaires or magazine to ask questions.
It is the most commonly used method of sampling because it is cheap incredibly prompt and uncomplicated.
Answer:
The correct option is;
D. Self-selected
Step-by-step explanation:
Self-selected sampling also known as volunteer sampling is a sampling method in which participants are those that voluntarily respond to an advert or to the request of the researcher who ask for members of the population to take part in the study
The magazine in the question has put out a survey of which the magazine is asking readers to complete and the readers can then decide if they wish to participate in the study which is a form of self-selected sampling.

A P E X
All options could change a taxpayer's adjusted gross income when filing a federal income tax return.
Options A, B, C, and D are the correct answers.
What is taxpayer-adjusted gross income?
Taxpayer-adjusted gross income (AGI) is a person's gross income (all income from various sources such as wages, self-employment, interest, dividends, and capital gains) minus certain deductions (such as contributions to a traditional IRA, alimony payments, and student loan interest).
We have,
- Medical and dental expenses are deductible if they exceed a certain percentage of the taxpayer's adjusted gross income.
- Contributions to an IRA may be deductible, which would lower the taxpayer's adjusted gross income.
- Casualty and theft losses may be deductible if they exceed a certain percentage of the taxpayer's adjusted gross income.
- Charitable contributions made are deductible if the taxpayer itemizes deductions, which would lower the taxpayer's adjusted gross income.
Thus,
All of the above could change a taxpayer's adjusted gross income when filing a federal income tax return.

tiffany states the following is not a function. explain to tiffany why the following represents a function
Answer:
Each x value occurs only once
Step-by-step explanation:
In order for something to be classified as a function, it must pass the vertical line test, meaning a vertical line should never hit 2 points on the function, meaning each x value appears once. Y values can occur as many times, as long as each x value occurs once, it is a function. In this case, a y value appears 2 times, but each x value only does so once.

If the sum of the squares of nonnegative real numbers a,b, and c is 39, and ab + bc + ca = 21, then what is the sum of a,b, and c?
Answer:
Step-by-step explanation:
a² + b² + c² = 39
ab + bc + ca = 21
(a + b + c)² = a² + b² +c² + 2[ab + bc +ca]
(a + b + c)² = 39 + 2*21
= 39 + 42
(a+ b + c)² = 81
a +b + c = √81 = √9*9
a + b + c = 9

Solve for I.
V = IR
What is I equal to?
Answer:
I=V/R
Step-by-step explanation:
In this equation, we see that there are no numerical values so we can't exactly solve for the exact number. Because of this, all you do Is isolate the variable "I" by itself. To do this, divide R on both sides. This way, you isolate I and on the other side you get V/R that cannot be further simplified.
Answer:
I=V/R
Step-by-step explanation:
V=IR
Divide both sides by R to isolate I
V/R=I

What is the slope of a line that is perpendicular to the line whose equation is 2y = 3x - 1? -3 - -
Answer: 2/3x
Step-by-step explanation:
First, you need to simplify your original line to point slope formula. Dividing the whole thing by 2 to get y by itself leaves you with
y = 3/2x - 1/2
Any perpendicular line has the opposite slope to the line it is perpendicular to, so you flip the slope to get 2/3x
A swimming pool is 22 feet long and 18 feet wide. How many feet of fencing are needed to enclose the pool
Answer:
80 feet
Step-by-step explanation:
length of pool = 22 , width of pool = 18
feet required for fencing the pool = 2 (l +b)
= 2 ( 22+18)
=2*40
=80feet
Answer:
Step-by-step explanation:
The pool is a rectangle as length and breadth are different.
Since they are asking about fencing you need to find the perimeter.
Length=22feet
Breadth=18feet
Perimeter of a rectangle = 2(l+b)
= 2 × 22 + 2×18
=44+36
=80 feet
Kostya randomly chooses a number from 1 to 10. What is the probability he chooses a number less than 5?
A. 1/2
B. 4/9
C. 2/5
D. 3/5
Answer:
Step-by-step explanation:
2/5
If Kostya randomly chooses a number from 1 to 10 then 2/5 is the probability Kostya chooses a number less than 5.
What is Probability?It is a branch of mathematics that deals with the occurrence of a random event.
Given that Kostya randomly chooses a number from 1 to 10.
We have to find the probability he chooses a number less than 5
There are four numbers that are less than 5 .
The numbers less than 5 are 1, 2, 3, 4.
The probability that Kostya randomly chooses one of these numbers is 4/10,
Divide numerator and denominator by 2
We get 2/5
Hence, if Kostya randomly chooses a number from 1 to 10 then 2/5 is the probability he chooses a number less than 5.

Find the diagonale of the base.
Answer: 8.94
Step-by-step explanation:
By common logic, you can say that l=8, w=4 and h=2.
The diagonal of the base can be found by using Pythagorean Theorem.
Pythagorean Theorem: a²+b²=c²
Since we know the a and b of the base, we can find c, the diagonal.
a and b is the l and w. We can use the equation to find c.
8²+4²=c²
64+16=c²
80=c²
c=√80
c≈8.94
The diagonal is approximately 8.94
Can someone help me find the slope , y-intercept ,and equation pls help it’s my finals
Answer:
slope: -3
y-intercept: -5
equation: y = -3x - 5
Step-by-step explanation:
The formula for slope is:
(y2 - y1)/(x2 - x1)
Let's use these coordinates:
(-1, -2)
(0, -5)
x1 = -1
x2 = 0
y1 = -2
y2 = -5
Substitute into the formula:
(y2 - y1)/(x2 - x1)
(-5 + 2)/(0 + 1)
Solve:
(-5 + 2)/(0 + 1)
-3/1
= -3
slope = -3
The y-intercept is when the x coordinate is 0.
Looking at the table, we see the coordinate (0, -5).
The y-coordinate is -5.
This means that the y-intercept is -5
y-intercept = -5
Slope-intercept form:
y = mx + b
where m is the slope and b is the y-intercept
m = -3
b = -5
Substitute:
y = mx + b
y = -3x - 5
