Answer: n= 15
p= 0.30
Step-by-step explanation:
Binomial distribution :
Let x be a binomial variable.
The probability of getting success in x trials is given by :-
, where n is the total number of trials and p is the probability of getting success in each trail.
Given : The proportion of parolees from prison return to prison within 3 years= 0.30
We assume that whether or not one prisoner returns to prison is independent of whether any of the others return to prison.
⇒ p =0.30
Let the random variable X be the number of parolees out of 15 that return to prison within 3 years.
⇒ n= 15

The answer is D assuming the equation is y=(1/4x)^2. If a number is attached to the x, the graph shows the reciprocal of the number and affects the graph horizontally. If the equation is y=1/4(x^2) then the answer is B, since it is affecting the equation as a whole and not just the x.
Answer:
Take the numbers 50 and 30. Their greatest common factor is 10, since 10 is the greatest factor that both numbers have in common. To find the GCF of greater numbers, you can factor each number to find their prime factors, identify the prime factors they have in common, and then multiply those together.
