Answer:

Correct option: B -> win $1

Step-by-step explanation:

Mariah will win for the values of 1, 4 or 6.

These are 3 out of 6 possible values of the die, so the probability of winning is 3/6 = 50%, and the probability of losing is 100% - 50% = 50%

The expected value for winning cases is the value times the probability, so:

E(win) = 4 * 0.5 = 2

The expected value for losing cases is:

E(lose) = -2 * 0.5 = -1

So the final expected money is:

E(total) = E(win) + E(lose) = 2 - 1 = 1

So she can expect to win $1

Correct option: B

Find the distance between the given points (4,1) and (-5, -2)
anyanavicka [17]

Answer:

3\sqrt{10} units I THINK

Step-by-step explanation:

using the distance formula, -2 - 1 = -3

-3 x -3 = 9

-5 - 4 = -9 x -9 = 81

81 + 9 = 90

sqrt 90 simplified is 3\sqrt{10}.

How many different books did the children read
Alex777 [14]

Answer:

16 books

Step-by-step explanation:

if Sandra read 5 books and Deacon read 6 and Breanna read 7 and they all one same book, then that means sandra read 4 different books then Deacon and Breanna. Deacon read 5 different books then Sandra and Breanna. Breanna read 6 different books then Deacon and Sandra.

So Sandras 4 books plus Deacons 5 books plus Breannas 6 books equals up to 15 but, now you need to add the one book they all read which makes the answer 16.

iren [92.7K]

Answer:

55% of the people surveyed were satisfied with the​ car

Step-by-step explanation:

The proportion of people surveyed who were satisfied with the car is the number of people who said they would buy that type of car again divided by the total number of people survied.

The percentage is the proportion multiplied by 100.

We have that:

2,300 people surveyed

1,265 said they would buy that type of car again.

1265/2300 = 0.55

0.55*100 = 55%

55% of the people surveyed were satisfied with the​ car
