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%.

The graph of a linear function f passes through the point (-2,-10) and has a slope of 5/2 what is the zero of f ?

Answers

Answer:

Check the explanation.

Step-by-step explanation:

As the graph of a linear function f passes through the point (-2,-10) and has a slope of 5/2.

As the slop-intercept form is given by:

[tex]y = mx+b[/tex]

where m is the slope and b is the y-intercept.

substituting the values (-2, -10) and m = 5/2 in the slop-intercept form to determine y-intercept.

[tex]y = mx+b[/tex]

[tex]-10=\frac{5}{2}\left(-2\right)+b[/tex]

[tex]-\frac{5}{2}\cdot \:2+b=-10[/tex]

[tex]-5+b=-10[/tex]

[tex]-5+b+5=-10+5[/tex]

[tex]b=-5[/tex]

And the equation of the line in the slope-intercept form will be:

[tex]y = mx+b[/tex]

putting b = -5 and slope = m = 5/2

[tex]y = mx+b[/tex]

[tex]y=\frac{5}{2}x+\left(-5\right)[/tex]

[tex]y=\frac{5}{2}x-5[/tex]

Determining the zero of function.

As we know that the real zero of a function is the x‐intercept(s) of the graph of the function.

so let us determine the value of x (zero of function) by setting y = 0.

[tex]0=\frac{5}{2}x-5[/tex]

[tex]\frac{5}{2}x-5=0[/tex]

[tex]\frac{5}{2}x=5[/tex]

[tex]5x=10[/tex]

[tex]x=2[/tex]

Therefore, the zeros of the function will be:

x = 2

Answers

9514 1404 393

Answer:

  x² -11x +18 = (x -9)(x -2)

Step-by-step explanation:

The x-coefficient is the sum of the constants in the binomial factors; the constant term is their product. It usually works well to look for factors of the constant that have the right sum. Here, both must be negative.

  18 = (-1)(-18) = (-2)(-9) = (-3)(-6)

The factors -2 and -9 have a sum of -11, so those are the binomial constants of interest. The factorization is ...

  x² -11x +18 = (x -9)(x -2)

gil borrows $8000 for college expenses. he will pay a total of $2280 back in interest after 6 years. what was his interest rate

Answers

Answer:

R = 41.8129%/year

Equation:

r = (1/t)(A/P - 1)

Calculation:

Solving our equation:

r = (1/6)((8000/2280) - 1) = 0.41812865

r = 0.41812865

Converting r decimal to R a percentage

R = 0.41812865 * 100 = 41.8129%/year

The interest rate required to get a total amount, principal plus interest, of $8,000.00 from simple interest on a principal of $2,280.00 over 6 years is 41.8129% per year.

Step-by-step explanation:

Answer:

I believe it is 4.75 %

Step-by-step explanation:

2,280 × 100 = 228,000

228,000 / 8,000 = 28.5

Answers

Answer:

495 ways

Step-by-step explanation:

Given that:

Total number of applicants (n) = 12

Required number (r) = 4

Using the combination formula :

nCr = n! / (n-r)!r!

12C4 = 12! / (12 - 4)!4!

12C4 = 12! / 8!4!

12C4 = (12*11*10*9) / 4*3*2*1

12C4 = 11880 / 24

= 495 ways

4x^2-21x-18=0
Find the discriminate

Answers

a = 4, b = -21, c = -18

to keep from getting "mixed up", evaluate the discriminant first ...

b<sup>2</sup> - 4ac = (-21)<sup>2</sup> - 4(4)(-18) = 729

sqrt(729) = 27

x = (21 +/- 27)/8

x = -3/4, x = 6

since the discriminant is a perfect square, the original quadratic will factor ...

4x<sup>2</sup> - 21x - 18 = 0

(4x + 3)(x - 6) = 0

x = -3/4, x = 6

Answer:729

Step-by-step explanation: Use the values of a, b and c to find the discriminant. Which is 729

JJ decides to leave a tip that is 15% of the original price for his meal. How much should he leave as tip for the $5.50 cheeseburger and $2.50 milkshake? Express your answer to the hundredths place?

Answers

Answer: $9.20

Step-by-step explanation: To get the answer, you add both the cost and multiply it by .15. Then you add the product to the number you got adding the cost of the food.

Answer:

$1.20

Step-by-step explanation:

He has to leave 100% of the cost which is $5.50 + 2.50 or $8.00.

He wants to leave 115% of the $8 he has to leave.

So you set it up like

x/8 = 115/100

Then you solve for x

8(115) = 920

920/100 =9.2

So he will leave $9.20.

It then asks for just how much the tip is that he will leave so

9.2 - 8 = 1.2

So the tip is $1.20.
