Answer:
Step-by-step explanation:
In this question, the Poisson distribution is used.
Poisson distribution:
In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:
In which
x is the number of sucesses
e = 2.71828 is the Euler number
is the mean in the given interval.
Parameter of 5.2 per square yard:
This means that
, in which r is the radius.
How large should the radius R of a circular sampling region be taken so that the probability of finding at least one in the region equals 0.99?
We want:

Thus:

We have that:


Then





Thus, the radius should be of at least 0.89.

I can't tell what the numbers are on the first one but you got the second one right, and the last one would be different it would be 24 I believe.
Answer:
Is not possible to compute the angle under those conditions.
Step-by-step explanation:
You need more information, I will be more specific, there is a book called "Geometry" by Moise Downs where the following theorem is stated on the chapter 7.
Let ΔABC and ΔDEF be two triangles where AB = DE and AC = DF if
∠A > ∠D then BC > EF, which in simple terms means that, if two sides are equal, the angle between them can vary as much as you want and that will directly imply the size of the third size of your triangle.
Therefore, there is information missing in order to solve the question
The answer is 32.72 degree.
