Answer:

Option B and E

Step-by-step explanation:

To find the solution we will check every option given in the question .

A. Right ⇒ none angle is 90°. false.

B. Scalene ⇒ all sides are different in measure.

So this triangle is scalene. True

C. Obtuse ⇒ None angle is more than 90° False

D. Isosceles ⇒For isosceles triangle at least two sides should be equal, but its an scalene triangle. False

E. Acute ⇒ All angles are less than 90° so its an acute triangle. True

F. Equilateral ⇒ All sides are different in measure so not an equilateral triangle False

Option B and E are the answer.

An animal shelter has a 58% adoption rate for puppies. Of all puppies in the shelter, 80% live to be 7 years or older. Of the pu

dexar [7]

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.

Solve the system by elimination.(show your work)

PilotLPTM [1.2K]

Answer:

x = 1 , y = 1 , z = 0

Step-by-step explanation by elimination:

Solve the following system:

{-2 x + 2 y + 3 z = 0 | (equation 1)

-2 x - y + z = -3 | (equation 2)

2 x + 3 y + 3 z = 5 | (equation 3)

Subtract equation 1 from equation 2:
