Answer:
The probability that the town has 30 or fewer residents with the illness = 0.00052.
Step-by-step explanation:
So, we have the following set of data or information or parameters given from the question above and they are; the number of people living in that particular society/community/town = 74,000 residents and the proportion of people that the diseases affected = .000215.
The first step to do is to determine the expected number of people with disease. Thus, the expected number of people with disease = 74,000 × .000215 = 15.91.
Hence, the probability that the town has 30 or fewer residents with the illness = 1.23 × 10^-7 × 15.91^30/ 2.65253 × 10^-32 = 0.00052.
Note the formula used in the calculating the probability that the town has 30 or fewer residents with the illness = e^-λ × λ^x/ x!

Answer:
Option A.
Step-by-step explanation:
Area of a square is
.... (1)
where, x is side length.
The length of each side of his square plot is decreasing at the constant rate of 2 feet/year.
It is given that bob currently owns 250,000 square feet of land.
Fist find the length of each side.
Taking square root on both sides.
Differentiate with respect to t.
Substitute x=500 and 
in the above equation.
Farmer bob is losing 2,000 square feet of land per year.
Therefore, the correct option is A.
10 kilometers is equal to a little over 6 miles. And 6 > 5, therefore 10 kilometers is your answer.
