Explanation:
It isn't clear what the elements of your flowchart are supposed to look like. In general, the proof would go like this:
1. List the "givens": PQ=6=TS; ∠P=120°=∠T; ∠PRQ and ∠TRS are vertical angles.
2. Note that the vertical angles are congruent
3. Claim ΔPRQ ≅ ΔTRS by the AAS congruence postulate since two corresponding adjacent angles and the corresponding sides not between them have been shown to be congruent.
Answer:
I think b
Step-by-step explanation:
A triangle always equals 180 degrees so to find the degree of angle c is you must find out what the other angles are . In this picture it shows that the triangle directly across from the triangle you are trying to figure out the angle for .They are identical triangles so that means that angle d is 24 degrees so you have 24 for one corner of the triangle . Angle d and c are identical also so that means angle c is also 24 degrees . So that means (if you were solving for the whole triangle) that angle c and d are both 24 degrees meaning the unknown angle or the top of the triangle would be 132 degrees. So the answer is C=24 degrees. Hope this helped atleast a little .
Answer:
Expected number of visits to the emergency room that would require a surgery is 336.
Step-by-step explanation:
Let <em>X</em> = number of surgery.
The odds of having a surgery in a randomly selected visit to a emergency room is 4 out of 10.
Then the probability of having a surgery in a randomly selected visit to a emergency room is:
In the past month a large urban hospital had 840 emergency visits.
An emergency room visit may lead to surgery or not is independent of the others.
The random variable <em>X</em> follows a Binomial distribution with parameters <em>n</em> = 840 and <em>p</em> = 0.40.
The expected value of a binomial random variable is:
Compute the expected number of visits that would require a surgery as follows:
Thus, expected number of visits to the emergency room that would require a surgery is 336.
