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.

Answer:
1/12
Step-by-step explanation:
Total sub consumed = ¼ + ⅔
= [3(1) + 4(2)]/12 (LCM is 12)
= 11/12
Left = 1 - 11/12 = 1/12
Find midpoint of segment.
(-1,1), (7,-5)
Find slope of line which passes through (-1,1) and (7,-5).
The slope of perpendicular line is negative reciprocal value of m.
Write quation of line which slope is
and passes throug the point (3,-2).
Answer:
9
Step-by-step explanation:
Area is measured in square units. For example in the rectangle above, if the sides are 2 and 4 meters long, then the area is 8 square meters. If the sides were 2 feet and 4 feet long the area would be 8 square feet. The most important thing to remember when calculating area is that.
