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.
z + 93 = 180
z = 87
Answer z = 87
Here are the answer for x and y, in case you need them.
x = 2* 93 - 112
x = 186 - 112
x = 74
y = 2 * 80 - x
y = 160 - 74
y = 86
Answer:
A
Step-by-step explanation:
X values cannot repeat in a function, 3 is used as an X value twice in A, and therefore cannot be a function.
If this is graphed, you can use the vertical line test, if a vertical line on any point goes through other points, it is not a function.
In this case, just check if X repeats.
It is d i did the test and got an a
1.y-4.90 = 2.4(x-1) 2. 24x-10y= -25
Step-by-step explanation:
The point-slope form of an equation is written as ;
y-y₁ = m(x-x₁) where the focus is on the slope of the line and a point on the line.
In this case, y-4.90 = 2.4(x-1)
The standard form an equation is written as :
Ax+By=C ,where x and y are variables and A,B and C are integers.
In this case; 24x-10y= -25
