Answer:`13H
Step-by-step explanation:
The distance between two points is found using something called the distance formula. The distance formula goes like this:
(x₂ - x₁) and the y equivalent is the same as the change between the x or y values between each coordinate. Using this formula, the distance between (5,-8) and (53,-28) is ~43.635
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
