Answers

Answer 1
Answer: so find total
35+7.5+6.6=49.1

18% of 49.1=0.18 times 49.1=8.838 round
tip=$8.84
Answer 2
Answer:

Answer:

the answer is 9.00

Step-by-step explanation:

Add all the courses to get the total cost of the meal:

Total cost = $35.90 + $7.50 + $6.60 = $50.00

Get 18% of the total, to compute the tip to be paid:

$50(18%) = $50(.18) = $9.00

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.
