How many quarts are in 10 cups?
2 answers:
Answer:
2.5 cups
Step-by-step explanation:
Total number of cups = 10 cups
Quarts means 1/4th of the total valu.
The number of quarts in a cap can be calculated by the formula:
Number of quarts of a cup = Total number of cups ÷ 4
Here, total number of cups = 10.
Number of quarts of a cup = .
Number of quarts of a cup = 2.5 cups.
Thus, the answer is 2.5 cups.

Answer:
B) Vertex (1,2), maximum
Step-by-step explanation:
First, determine if the graph has a maximum or a minimum value. Since the graph opens downwards, it has a <u>maximum</u> value.
The maximum is the point that has the greatest y value. We can see that the greatest y value is at . Going down two units from that spot, we can see that the x value is at
. We can plug those into the vertex form,
. By plugging in we get the point
.
Answer:
There is a 28.57% probability that a randomly selected participant who died by the end of the study was a non-smoker.
Step-by-step explanation:
We have the following probabilities:
A 15% probability that a participant is classified as a heavy smoker.
A 25% probability that a participant is classified as a light smoker.
A 100% - 25% - 15% = 60% probability that a participant is classified as a non smoker.
A x% probability that a non smoker dies.
A 3x% probability that a light smoker dies.
A 5x% probability that a heavy smoker dies.
This can be formulated as the following problem:
What is the probability of B happening, knowing that A has happened.
It can be calculated by the following formula
Where P(B) is the probability of B happening, P(A/B) is the probability of A happening knowing that B happened and P(A) is the probability of A happening.
This problem is:
What is the probability of the participant being a non-smoker, given that he died?
P(B) is the probability that the participant is a non smoker. So
P(A/B) is the probability that the participant dies, given that he is a non smoker. So:
P(A) is the probability that the participant dies:
is the probability that a heavy smoker is selected and that he dies. So:
is the probability that a light smoker is selected and that he dies. So:
is the probability that a non-smoker is selected and that he dies. So:
The probability that a participant dies is:
The probability of the participant being a non-smoker, given that he died, is:
There is a 28.57% probability that a randomly selected participant who died by the end of the study was a non-smoker.
