180 - 101 = 79
Supplementary mean that the two angle measures add up to equal 180
Total amount spent on 4.6 pounds of ground beef = $16.33
We have to determine the amount spend on 3 pounds of ground beef.
We will use unitary method to solve this problem.
So, amount spent on 1 pound of ground beef =
= $3.55
So, amount earned on 3 pounds of ground beef =
= $10.65
Therefore, Lena will spend $10.65 on 3 pounds of ground beef.
So, Option C is the correct answer.
3/8 is bigger as it is 0.375
Answer:
P(A∩B) = 0.522
Step-by-step explanation:
Let's call A the event that a puppy is adopted and B the probability that a puppy live 7 or more years
So, the probability P(A∩B) that a randomly selected puppy in the shelter will get adopted and live 7 or more years is:
P(A∩B) = P(A)*P(B/A)
Because A and B are not independents.
Then, the probability P(A) that a puppy is adopted is 58% and the probability P(B/A) that a puppy live 7 or more years given that the puppy is adopted is 90%.
Finally, replacing the values, we get:
P(A∩B) = 0.58*0.9 = 0.522
It means that the 52.2% of the puppies are adopted and live 7 or more years.
