The polynomial p(x) can be found by multiplying 'x-3' to every term
Now distribute and you have your answer.

Step-by-step explanation:
Answer:
Step-by-step explanation:
y = 3*2 + 9x - 18
First step in this case is to multiply 3 * 2 = 6.
Then you would have: 6 + 9x - 18
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
