Answer:
$28.91
Step-by-step explanation:
The first step is to calculate the amount of the tip. You multiply the price (24.50) by the tip amount (18% or 0.18). The product is 4.41. Then, you add the tip to the bill. 24.50+4.41=28.91.
Answer:
Therefore, the probability is P=0.0084.
Step-by-step explanation:
We know that a multiple-choice test in which each question has 4 choices only one of which is correct. Assume that 9 questions are answered by guessing randomly.
Because we have 4 choices only one of which is correct, we get that p=0.25 and q=0.75.
We calculate the probability of getting exactly 6 correct answers.
n=9 and k=6.
Therefore, the probability is P=0.0084.
Answer:
3/20 or 15%
Step-by-step explanation:
Out of 1,2,3,4, and 5, there are 3 prime numbers. This makes the odds of selecting one of those prime numbers 3/5. Then, saying that he does pick a prime number and discards that card, there are now four cards, one of them being the number one. His chances of selecting this card is 1/4.
To find the probability you need to multiply the two probabilities together.
3/5 times 1/4 is 3/20.
So your answer is 3/20 or 15%.
Answer:
Answer:
have a common denominator first,
