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.
Take cost divide by total ex. 650 divided by 1560 is ur percentage after u multiply by 100
Answer:
The answer is approximately 2.21456
Step-by-step explanation:
1. You simplify your equation to:
5x^3-11x-30=0
2. Now you can use the Newton Raphson method to solve this problem.
The Newton Raphson method can be used by calculating x + 1 until its delta turns into something below 0.00001, and the x value is your answer.
Answer:
m = -1/2 and b = 2.5
Step-by-step explanation:
The slope intercept form of the equation of a line is
y = mx+b where m is the slope and b is the y intercept
2.5 - 1/2x = y
Rewriting
y = -1/2x +2.5
The slope is -1/2 and the y intercept is 2.5
m = -1/2 and b = 2.5
