Remember the bracket that I placed
Answer:
No
Step-by-step explanation:
Triangles have 180 degrees total. Once you take away 90 from it being a right triangle, you have 90 degrees left. For an angle to be right or obtuse it would have to be over 90 degrees, therefore, A right triangle has one right angle and two acute angles.
Answer:
D
Step-by-step explanation:
= 34/5 × 19/4
= 646/20
= 
Explanation:
Lets interpret Z with M trials. First we have M trials, each trial can be a success or not. The number of success is called N. Each trial that is a success becomes a trial, and if it is a success it becomes a success for Z. Thus, in order for a trial to be successful, it needs first to be successful for the random variable N (and it is with probability q), and given that, it should be a success among the N trials of the original definition of Z (with probability p).
This gives us that each trial has probability pq of being successful. Note that this probability is pq independently of the results of the other trials, because the results of the trials of both N and the original definition of Z are independent. This shows us that Z is the total amount of success within M independent trials of an experiment with pq probability of success in each one. Therefore, Z has Binomial distribution with parameters pq and M.
