Answer:
The expected number of seat belt wearing drivers among the five cars is 3.75, using the expected value of a binomial experiment.
Step-by-step explanation:
For each driver, there are only two possible outcomes. Either they wear their seatbelts, or they do not. This means that we solve this problem using concepts of the binomial probability distribution.
Binomial probability disitribution.
Probability of exactly x sucesses on n repeated trials, with p probability.
Has an expected value of:
.
(a) Describe how you would simulate the number of seat belt wearing drivers among the five cars.
You would simulate this number finding the expected value of the binomial experiment.
There are 5 cars, so .
75% of all drivers wear their seat belts, so .
So the expected number of seat belt wearing drivers among the five cars is:
The expected number of seat belt wearing drivers among the five cars is 3.75, using the expected value of a binomial experiment.

Area= 190
height= 2(width) - 1
area= length times width
190= (2(width) -1) x width
190 = 2w^2-w
w^2-w-190 = 0
use quadratic fomula, you'll get w= 10
so height will be 2(10)-1 = 19
