Find the coordinates of the vertices after the given transformation. Reflection across x=-2. W(-4,-4)

Answers

Answer:

To reflect a point across the vertical line x = -2, we can use the formula:

(x, y) → (2c - x, y)

where c is the x-coordinate of the line of reflection. In this case, c = -2. Let's apply this formula to the point W(-4, -4):

W' = (2(-2) - (-4), -4)

= (-4 + 4, -4)

= (0, -4)

Therefore, after the reflection across x = -2, the coordinates of W(-4, -4) become W'(0, -4).

HURRY PLEASE!!! Miguel is playing a game in which a box contains four chips with numbers written on them. Two of the chips have the number 1, one chip has the number 3, and the other chip has the number 5. Miguel must choose two chips, and if both chips have the same number, he wins $2. If the two chips he chooses have different numbers, he loses $1 (–$1).

A))))). Let X = the amount of money Miguel will receive or owe. Fill out the missing values in the table. (Hint: The total possible outcomes are six because there are four chips and you are choosing two of them.)

(There is a graph to fill out here) (It is the attached media)


B))))). What is Miguel’s expected value from playing the game?



C))))). Based on the expected value in the previous step, how much money should Miguel expect to win or lose each time he plays?


D))))). What value should be assigned to choosing two chips with the number 1 to make the game fair? Explain your answer using a complete sentence and/or an equation.

Answers

Answer:the anser is a

Step-by-step explanation:

To check all the events (6), we label the chips. Suppose one chip with 1 is labeled R1 and the other B1 (as if they were red and blue). Now, lets take all combinations; for the first chip, we have 4 choices and for the 2nd chip we have 3 remaining choices. Thus there are 12 combinations. Since we dont care about the order, there are only 6 combinations since for example R1, 3 is the same as 3, R1 for us.

The combinations are: (R1, B1), (R1, 3), (R1, 5), (B1, 3), (B1, 5), (3,5)

We have that in 1 out of the 6 events, Miguel wins 2$ and in five out of the 6 events, he loses one. The expected value of this bet is: 1/6*2+5/6*(-1)=-3/6=-0.5$. In general, the expected value of the bet is the sum of taking the probabilities of the outcome multiplied by the outcome; here, there is a 1/6 probability of getting the same 2 chips and so on. On average, Miguel loses half a dollar every time he plays.

The sales tax in bills state is 6% Bill bought a scionon having a sales tax of $820 what was the cost of the car round to the nearest dollar

Answers

so if you get 20% of 13,668 you get 820.08
 If you get 20% of 13,666 you get 819.96
If you get 20% of 13,667 you get 820.02
and if you get 20% of 13,665 you get 819.90
so if they want you to round the cents then 13,666 would be your answer because when you do this ----> 13,666X.06=819.96 you might have to round the 6 to 9 which makes 819.96 into 820 so answer is B

A DVD store charges $4.70 for each day, a DVD is rented. The store also gives you a dollar off if the DVD is returned before 5 days. a.Write a rule to represent the rental charges. b. How much will you pay if you return the DVD after 4 days? 7 days?

Answers

Answer:

For four days it would be $19.8. For seven days it would be $24.9

Step-by-step explanation:

4 days:

$4.70 x 4 + 1= 19.8

7 days:

$4.70 x 7 = $24.9

I took away 1 from the 4 day equation because the question said you get a dollar off if you return the dvd before 5 days.

Hope this helps!

4.5x + 1.5y = 24 ⇒ 4.5x + 1.5y = 24
1.0x -  1.0y = 4   ⇒ 4.5x - 4.5y = 18

                             4.5x + 1.5(1) = 24
                                 4.5x + 1.5 = 24
                                          - 1.5    - 1.5
