Answer: a) 4.6798, and b) 19.8%.
Step-by-step explanation:
Since we have given that
P(n) = 
As we know the poisson process, we get that

So, for exactly one car would be
P(n=1) is given by

Hence, our required probability is 0.2599.
a. Approximate the number of these intervals in which exactly one car arrives
Number of these intervals in which exactly one car arrives is given by

We will find the traffic flow q such that

b. Estimate the percentage of time headways that will be 14 seconds or greater.
so, it becomes,

Hence, a) 4.6798, and b) 19.8%.

Step-by-step explanation:
Can you be a little more specific? Put the whole question or something... Hope I can help! :)
Draw a picture of the yard, rectangle. On the two long sides, write 28 yards and on the two shorter ones, just write a question mark.
To figure out perimeter, you need to add up each side.
P = Perimeter
L = Length
W = Width
P = L(2) + W(2)
If the length is 28, double it. = 56
Now subtract that from the perimeter - 88-56=32
32 is what you have left, so now split that, and replace the question marks.
All-in-all each width is 16 yards, while each length is 28, making the whole rectangle have a perimeter of 88 yards.
