Answer: No, it is not a right triangle.
Explanation:
9^2 + 7^2 (?) 12^2
81 + 49 (?) 144
130 = 144
Since 12^2 = 144, and the square root of 130 is 11.4^2, it is not a right triangle.
The conditional probability that a Philadelphian who got the flu got a flu shot is of:
0.4375 = 43.75%.
<h3>What is Conditional Probability?</h3>
Conditional probability is the probability of one event happening, considering the outcome of a previous event.
The formula is presented as follows:

In which each probability in the formula is described as follows:
- P(B|A) is the probability of the event B happening, given that the event A happened.
is the probability of both the events A and B happening.
- P(A) is the probability of the event A happening.
In the context of this problem, the events are described as follows:
- Event B: Got the flu shot.
The probability of people who got the flu is obtained as follows:
- 2% of 70%. (got the shot).
- 6% of 30%. (did not get the shot).
Hence:
P(A) = 0.02 x 0.7 + 0.06 x 0.3 = 0.032.
The probability of both getting the flu and the shot is:
P(A and B) = 0.02 x 0.7 = 0.014.
Hence the conditional probability that a Philadelphian who got the flu got a flu shot is calculated applying the conditional probability formula as follows:
P(B|A) = P(A and B)/P(A) = 0.014/0.032 = 0.4375 = 43.75%.

The answer to your question is C.
Answer:
x = 12 , y = 60
Step-by-step explanation:
The figure has 2 pairs of parallel sides and is therefore a parallelogram.
The opposite sides and opposite angles are congruent , then
x + 3 = 15 ( subtract 3 from both sides )
x = 12
and y = 60
