The number of DVDs that will be checked out for every 100 patrons will be 20.
<h3>How to find that a given condition can be modeled by binomial distribution?</h3>
Binomial distributions consist of n independent Bernoulli trials.
Bernoulli trials are those trials that end up randomly either on success (with probability p) or on failures( with probability 1- p = q (say))
Suppose we have random variable X pertaining to a binomial distribution with parameters n and p, then it is written as
The probability that out of n trials, there'd be x successes is given by
The expected value of X will be:
The information is given in the table.
The probability of getting DVDs will be
The value of n is 100.
Then the number of DVDs that will be checked out for every 100 patrons will be

#SPJ1
P = 2l + 2w
p-2w = 2l
p-2w/2 = l
Substitute the perimeter and you should be able to work it out
Answer:
Step-by-step explanation:
use the distance formula.
x1=-1
x2=1
y1=4
y2=-2
d=√((x2-x1)^2+(y2-y1)^2)
d=√(30) or 5.4772
We are given that Kristine spends $20 and saves the rest each time she get paid.
We can use slope-intercept form y=mx+b to represent the equation.
Where x represents the amount Kristine earns and y represents the amount she saves.
Kristine spends $20. Therefore b= -20.
Plugging mx as just x and b=-20.
<h3>y = x-20.</h3><h3>If we plug y=0, we get </h3><h3>0 = x-20</h3><h3>x=20.</h3><h3>We can see in 4th option we have x-intercept =20.</h3><h3>Therefore, correct option is 4th option. </h3><h3 />
The correct answer to this question is 1/5. To solve this, since 90 numbers exist in the range from 10 to 99, and 18 of them are divisible by 5, place these two numbers into the formula for probability.
Probability = target outcomes / total outcomes = 18 / 90
= 1/5
