Trina is making a graph that shows a proportional relationship between the amount of money collected, y, and the number of tickets sold, x. She correctly plots the point (600, 1,950). Which of these statements are true? Select all that are correct.
(The point (140, 455) is on the graph because $455 will be collected if 140 tickets are sold.)
(The constant of proportionality is 600/1,950, which is about 31)
(The point (5,16.25) is not on the graph because it is impossible to sell 16.25 tickets.)
(The point (1,3.25) is on the graph and identifies that the cost for each ticket is $3.25.)
(The point (0,0) is on the graph because 0,0 is on the graph of all proportional relationships.)

Answer:

4.375

Step-by-step explanation:

Taking off the length, we know you need to subtract. We can write out the answer as 8-3.625 which is 4.375.

Answer:

8904 People

Step-by-step explanation:

We start by the equation L = 12E, where L represents the population of Linton and E represents the population of Ellmore. We then set L + E = 9646, but since L = 12E, we then get 12E + E = 9636, or 13E = 9646. Therefore, E = 742. L = 12E, so L = 8904.

Answer:

The expected value of X is $0.2222.

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

For each dice, there are 6 possible outcomes(values from 1 to 6). So for 2 dices, there are [tex]6^2 = 36[/tex] possible outcomes.

Desired outcomes:

Sum 5: (1,4), (2,3), (3,2), (4,1).

Sum 6: (1,5),(2,4),(3,3),(4,2),(5,1)

Sum 7: (1,6), (2,5), (3,4), (4,3), (5,2), (6,1)

Sum of 9: (3,6), (4,5), (5,4), (6,3);

Sum of 12: (6,6)

Probabilities:

4 + 4 = 8 outcomes with a sum of 5 or 9.

8/36 = 2/9 probability of a sum of 5 or 9.

12 outcomes with a sum of 6, 7 or 12.

12/36 = 1/3 probability of the sum being 6, 7 or 12.

36 - 20 = 16 outcomes in which the sum is any other value. So

16/36 = 4/9 probability of a sum of any other value.

What is the expected value of X?

2/9 probability of earning $6.

1/3 = 3/9 probability of earning $2.

4/9 probability of losing $4.

Multiplying each outcome by its probability, we find the expected value. So

[tex]E = \frac{2}{9}*6 + \frac{3}{9}*2 - \frac{4}{9}*4 = \frac{12 + 6 - 16}{9} = \frac{2}{9} = 0.2222[/tex]

The expected value of X is $0.2222.

Answer:

$520

Step-by-step explanation:

1% of x is x times 0.01.

that means 10%of x is x times 0.1.

400 times 0.1 is 40.

40 is 10% of 400.

it was marked up by 30% so we need to times by 3.

40 times 3 is 120.

it was marked up so its addition.

400+120=520

Answer:

I can't see the options, so i will find all the asymptotes.

We have the function:

[tex]f(x) = \frac{x^4 - 4*x^2 + x}{-2*x^4 + 18*x^2}[/tex]

First, we can graph this using a graphing tool, the graph can be seen below.

In the graph, we can see that when we approach x = 0 from the left, f(x) goes to negative infinity, while if we approach x = 0 from the right, f(x) goes to infinity.

This can be written as:

[tex]\lim_{x \to 0_-} f(x) = - \infty \\[/tex]

and:

[tex]\lim_{x \to 0_+} f(x) = + \infty \\[/tex]

A similar thing can be seen at x = 3, when we approach from the left f(x) goes to infinity, while if we approach from the left, f(x) goes to negative infinity.

Then:

[tex]\lim_{x \to 3_-} f(x) = \infty \\\\\lim_{x \to 3_+} f(x) = - \infty \\[/tex]

For x = -3 we can see that when we approach from the left, f(x) goes to negative infinity, while if we approach from the right, f(x) goes to infinity.

Then:

[tex]\lim_{x \to -3_-} f(x) = - \infty \\\\\lim_{x \to -3_+} f(x) = + \infty \\[/tex]

We also can see that as x goes to negative infinity or positive infinity, f(x) tends to -0.5

Then:

[tex]\lim_{x \to \infty} f(x) = -0.5 \\ \lim_{x \to -\infty} f(x) = -0.5[/tex]

So you need to check the options that match with some of the given tendencies.

Answer:

Option c ==> 5/12 is the answer

Answer:

61.3°

Step-by-step explanation:

For angle x, 12 is the adjacent leg. 25 is the hypotenuse.

The trig ratio that relates the adjacent leg and the hypotenuse is the cosine.

cos A = adj/hyp

cos x = 12/25

x = cos^-1 12/25

x = 61.3°

Happy

|

Not happy

Here, we have a contingency table formatted in rows and columns

The columns = 3

The rows = 2

Degree of freedom :

(rows - 1) * ( columns - 1)

(2 - 1) * (3 - 1)

1 * 2

= 2

The degree of freedom = 2

Answer: True

Step-by-step explanation:

Answer: x = 3 - sqrt 17 / 2 , x = 3 + sqrt 17 / 2

Step-by-step explanation:

2x^2 = 4 + 6x

divide both sides by 2

x^2 = 2 + 3x

move expression to the left

x^2 - 2 - 3x = 0

reorder the terms

x^2 - 3x - 2 = 0

use the quadratic formula

x = - (-3) +- sqrt (-3)^2 - 4 x (-2) / 2 x 1

calculate

x = 3 +- sqrt 17 / 2

answer

x = 3 - sqrt 17 / 2 , x = 3 + sqrt 17 / 2
