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.
Answer:
70
Step-by-step explanation:
(5x2) x 7
(10) x 7 = 70
Dodecahedron is a 3D shape, usually when it ends with hedron it is 3D.
1.086 rounded to the nearest whole number would remain as one.
This is due to the fact that the tenths place does not have any number, and due to this the whole number would remain one.
If the number were to change, it would look as the following:
1.5 rounded to the nearest whole number 2.
