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%.
Answer:
Step-by-step explanation:
-We can use the exponential decay function to estimate the size after 13 years:
Where:
is the size after t years, t is the time, r is the rate of decay and
the original size.
#We substitute and calculate as:
Hence, the forest covers after 13 years.
