Answer:
Pr(X >42) = Pr( Z > -2.344)
= Pr( Z< 2.344) = 0.9905
Step-by-step explanation:
The scenario presented can be modeled by a binomial model;
The probability of success is, p = 0.65
There are n = 80 independent trials
Let X denote the number of drivers that wear a seat belt, then we are to find the probability that X is greater than 42;
Pr(X > 42)
In this case we can use the normal approximation to the binomial model;
mu = n*p = 80(0.65) = 52
sigma^2 = n*p*(1-p) = 18.2
Pr(X >42) = Pr( Z > -2.344)
= Pr( Z< 2.344) = 0.9905
No 3/4 is bigger
if you multiply the top and bottom of 3/4 by 4, you get 12/16.
11/16 <12/16
Answer:
I think it is in order
Step-by-step explanation:
not to sure though sorry
Answer: YES
Plug in the numbers in your head.
y=3(10)+7
y=30+7
y=37 which is the y intercept
In the blank the answer is x axis
