Which is the answer!!!
Answers
The best example of nonresponse bias from the scenario of this airline surveying customers is that Satisfied customers might be less likely to complete the survey than dissatisfied customers.
What is nonresponse bias?Nonresponse bias refers to a situation that arises where people are less inclined to provide feedback because their experience was different from those who did.
Satisfied customers would be less inclined to talk about their overall satisfaction than unsatisfied customers as the latter would use the opportunity to make their dissatisfaction known.

12 is 30% of ____
(Please explain)
Answers
Answer:
40
Step-by-step explanation:
In word problems, the word "of" usually means multiply. Thus, for example, 10% of $50 is $5. This is because we can write 10% as 0.10 or as 10/100 (which is 1/10) and then multiply: (1/10)(50) = 5
So, we often see equations like:
R = (1/2)D meaning R is 50% of D, or R is half of D
Let x = the number we want to find
This problem says:
"12 is 30% of what number?"
12 = (30/100) * x
12 = (3/10)x
(10/3)12 = x [multiply both sides by (10/3)]
40 = x
Checking (very important):
Is 12 = (3/10)(40) ?
12 = (3)(4) ?
12 = 12 ? yes
Answer:
40
Step-by-step explanation:
Let x = unknown number
30% = 30/100 = 0.3
If 12 is 30% of x, then
30% of x is 12
⇒ 0.3x = 12
⇒ x = 12 ÷ 0.3
⇒ x = 40
Or, you can divide 12 by 3 to get 10% and then multiply this by 10 to get 100%:
12 ÷ 3 = 4 (so 4 is 10%)
4 × 10 = 40 (which is 100%)

The ordered pairs in the table lie in the graph of the linear function whose equation is
y = 3x + 2.
Which ordered pair does not lie on the graph of this function?
A. (10, 32)
B. (8, 13)
C. (–5, –13)
D. (–8, –22)
Answers
y = 3x + 2 = 3 * x + 2
point (10 ; 32) on the line ?
so here we can read : x = 10 and y = 32
if x = 10
then y has to be = 3 * 10 + 2 = 30 + 2 = 32
so yes - on the line
same reasoning for the rest
The ordered pairs which does not lie on the graph of the function are (8,13).
What is function?Function is relationship between two or more variables expressed in equal to form. In a function each value of x must have corresponding value of y.
The value which we put in the function is domain of the function and the value which we will get is known as codomain of the function.
How to find ordered pairs?We have been given a function y=3x+2 and we have to find the ordered pairs which does not lie on graph of function. The ordered pairs which lie on the graph must satisfy the function and the ordered pairs which does not lie on the graph must not satisfy the function.
First ordered pair is (10,32)
32=3*10+2
32=30+2
32=32
It lies on graph.
Second ordered pair is (8,13)
12=3*8+2
12=24+2
12≠26
So it does not lie on graph of function y=3x+2.
Hence the ordered pair which does not lie on the graph of function y=3x+2 is (8,13).

Range of a function is the extent to which any function may be varied. The range of the given function y= -3sin(x)-4 is [-7,-1].
What is a Range?The range of a function is the extent to which any function may be varied.
We know that the general range of the function of sin(x) is between [-1,1].
-1 ≤ sin(x) ≤ 1. . . . . . . . . .(A)
As our required function is y = -3sin(x) - 4
Now, in order to get this function, we will multiply each side in Equation (A) by -3, therefore,
-3 ≤ -3 sin(x) ≤ 3
Further, subtract from 4 from each side of the equation.
-7 ≥ -3sin(x)-4 ≥ -1
Hence, the range of the given function y= -3sin(x)-4 is [-7,-1].

lea has dimes and nickels that total to $5.50. there are a total of 75 coins. how many are dimes?
Answers
Let d be the number of dimes and n be the number of nickels. Then (because there are 75 coins), d + n = 75
Also, you can figure out the value of the money you have by multiplying the number of dimes by 0.10 and multiplying the number of nickels by 0.05. That means 0.10d + 0.05n = 6.25
This gives you 2 equations with the 2 unknowns (d and n). You can solve this in several ways, including substitution and elimination. I'll go with substitution because that's usually the first method taught.
If d + n = 75, then d = 75 - n (subtract "n" from both sides of the equation). Now since "d" is the same as "75 - n" you can plug into the second equation "75 - n" wherever you see "d". That gives you:
0.10(75 - n) + 0.05n = 6.25
7.5 - 0.10n + 0.05n = 6.25 (distributing to eliminate the parenthesis)
7.5 - 0.05n = 6.25 (combining like terms)
-0.05n = -1.25 (subtracting 7.5 from both sides)
n = 25 (dividing both sides by -0.05)
So there are 25 nickels.
Since d + n = 75, you can plug 25 in for n to get:
d + 25 = 75
d = 50 (subtracting 25 from both sides)
So there are 50 dimes

112 = 14 x 8 = 28 x 4
28 = 14 x 2 = 28 x 1
Remove the 28 common factor.
Therefore,
