Answer:
There is a 99.44% probability that the squad will have at most 2 calls in an hour.
Step-by-step explanation:
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 time interval.
In this problem, we have that:
2.83 rescues every eight hours.
What is the probability that the squad will have at most 2 calls in an hour?
This is
We have 2.83 rescues every 8 hours. So for an hour, we have
So
So
There is a 99.44% probability that the squad will have at most 2 calls in an hour.
Answer:
(4x + 3) 2
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
The angle on the right side of the triangle is 10° ( alternate angle )
Since the triangle is right with hypotenuse x use the sine ratio to solve for x
sin10° = =
Multiply both sides by x
x × sin10° = 200 ( divide both sides by sin10° )
x = ≈ 1, 151.8 m
