Answer: The probability that none of the calls would result in a reservation would be 0.72%.

Since there is an 18% chance that there would be a reservation, then there is a 72% chance that there is not a reservation.

Our goal is to determine the likelihood that there are no calls. Or that the 72% chance event happens 15 times.

We can use the following expression to find that repeated probability.

(0.72)^15 = 0.0072 or 0.72%

Sam solved the following problem:
Talja [164]

Answer:

 Sam made it -24 versus 24  (29-5=24  not -24)

(Sam failed to flip the inequality)

Step-by-step explanation:

-4x + 5 > 29

Subtract 5 from each side

-4x+5-5 > 29-5

-4x > 24      Sam made it -24 versus 24  (29-5=24  not -24)

Divide by -4  Remember to flip the inequality

-4x/-4 < 24/-4   (Sam failed to flip the inequality)

x < -6

A pair of boots that originally sold for $75.32 are on sale for 22% off.
Vesnalui [34]

Answer:

The boots will be $58.75

Step-by-step explanation:

first you cross multiply

\frac{x}{75.32} x \frac{22}{100}

you then get 1,657.04= 100x, so divide by 100 on both sides to get

16.5704 = X  

Subtract X (the 22% discount amount) from the original price to get the new price of $58.75!

A tournament is being run between two teams, A and B. This is a 2- tournament meaning that the first team to win 2 games is the
natta225 [31]

Answer:

Step-by-step explanation:

For first game PA = 1/3

For second game PA = 1/3 ( If A is not lost in first game )

 = 2/5 (If A is lost in first game )

For conclusion of game in three matches :

If A wins , the probability is

PA , PB , PA  = 1/3 X 2/3 X 3/5 = 6/45

PB , PA , PA = 2/3 X 3/5 X 1/3 = 6/45

If B wins

PA, PB, PB = 1/3 X 2/3 X 2/5 =  4/ 45

PB, PA , PB = 2/3 X 3/5 X 2/3 = 4 / 15

Total probability of conclusion of game in 3 matches

= 6/45 +6/45 + 4/45 +4/15 = 28/45

b )

For the game concluding in 2 matches , the probability are as follows

PA,PA = 1/3 X 1/3 = 1/9

PBPB = 2/3 X 2/5 = 4 / 15

Total probability

= 1/9 + 4/15 = 17/45

So PA = 1/9 / 17/45

= 5/17
