You want to know the opinions of drivers with valid licenses across America on the issue of establishing a law that requires individuals to take and pass another driver's test at the age of 65 to determine whether they may retain their license. You obtain a list of all licensed drivers and mail a survey to a random sample of 10,000 drivers. Of those, 6,457 responded and 46% say they favor the test. Which of the following statements is true? (5 points)

A. Because random sampling is used, we can feel confident that the percentage of all
drivers with a valid license who say they favor the test is close to 46%.
B. The results of this survey may be affected by nonresponse bias.
C. We cannot trust these results because the survey was mailed. Only survey results
from face-to-face interviews are considered valid.
D. Because more than half of those who were mailed the survey actually responded,
we can feel fairly confident that the actual percentage of all drivers with a valid
license who say they favor another test is close to 46%.

question 1. (20)X = 100

question 2. the last one

Step-by-step explanation:

Answer:

Step-by-step explanation:

1.  20 a yard and made 100. 100/20=5 yards

20x=100

2. Since they don't give the number of yards they did mow, this would be my answer. I would say half the amount. Since they cut their rates in half, they'll have to cut twice as many to even the amount as before. They would have to cut three - four times as many to make over the original amount. They only have one weekend, so that'll be hard.

Answer:

f(x) = 7.75x + 12.5

The slope represents the cost per movie ticket.

The intercept represents the flat fee paid to see movies.

Step-by-step explanation:

From the data given :

When x = 3 ; f(x) = 35.75

When x = 5 ; f(x) = 51. 25

Linear function :

y = mx + c

f(x) = mx + c

m = slope ; c = intercept

35.75 = 3m + c - - - (1)

51.25 = 5m + c - - - (2)

Subtract

-15.5 = - 2m

m = 15.5 / 2

m = 7.75

From (1)

35.75 = 3m + c

35.75 = 3(7.75) + c

35.75 = 23.25 + c

c = 35.75 - 23.25

c = 12.5

y = 7.75x + 12.5

f(x) = 7.75x + 12.5

B.) The slope represents the cost per movie ticket.

The intercept represents the flat fee paid to see movies.

Answer:

The point that represents the bottom of the pool is [tex](x,y) = (-4, -16)[/tex].

Step-by-step explanation:

Given that the shape of the underground pool is a parabola, that is, a second order polynomial. Then, the point that represents the bottom of the pool is the vertex, which is contained in the standard form of the parabola. That is:

[tex]y-k = C\cdot (x-h)^{2}[/tex] (1)

Where:

[tex]x[/tex] - Independent variable, dimensionless.

[tex]y[/tex] - Dependent variable, dimensionless.

[tex]h[/tex], [tex]k[/tex] - Coordinates of the vertex, dimensionless.

[tex]C[/tex] - Constant, dimensionless.

The parabola is represented by [tex]f(x) = x^{2}+8\cdot x[/tex] and we proceed to transform into the desired form:

1) [tex]f(x) = x^{2}+8\cdot x[/tex] Given.

2) [tex]f(x) = (x^{2}+8\cdot x + 16)-16[/tex] Modulative property/Existence of the additive inverse.

3) [tex]f(x) +16 = (x+4)^{2}[/tex] Compatibility with the addition/Modulative property/Existence of the additive inverse/Perfect square trinomial.

4) [tex]y + 16 = (x+4)^{2}[/tex] Notation/Result.

Hence, the point that represents the bottom of the pool is [tex](x,y) = (-4, -16)[/tex].

Step-by-step explanation:

Answer:

y+10 = -5(x-3)

Explaination:

Finding the slope intercept form provides you with the line your looking for

here you want to isolate y

y = -5(x-3)-10

and then ditrubute the -5 into the parenthesis

y = -5+15-10

Combine like terms

y = -5x +5

and by looking at this in terms on y=mx+b

the line will intercept the y-axis at (5,0) like the line above shows

Answer:

y = 75x +1

is the correct answer hope it is helpful to you ☺️

The linear equation for this situation is,

⇒ y = 75x

And, There are 75 apple pick in one hour.

What is linear expression?

A linear expression is an algebraic statement where each term is either a constant or a variable raised to the first power.

Given that;

The graph shows how many apples Erin can pick if she ,maintain a constant rate.

Now,

Let two points on the graph are (0, 0) and (1, 75).

So, Slope of the graph (m) = (75 - 0) / (1 - 0)

                                         = 75

Thus, The linear equation is;

⇒ y - y₁ = m (x - x₁)

⇒ y - 0 = 75 (x - 0)

⇒ y = 75x

Where, y is number of apples and x is number of hour.

Thus, Number of apple pick in one hour is;

⇒ y = 75 x 1

⇒ y = 75

So, There are 75 apple pick in one hour.

Therefore, The linear equation for this situation is,

⇒ y = 75x

And, There are 75 apple pick in one hour.
