Answer:
0.1512 = 15.12% probability that fewer than four tornadoes occur in a three-week period.
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 interval.
In a given region, the number of tornadoes in a one-week period is modeled by a Poisson distribution with mean 2
Three weeks, so
Calculate the probability that fewer than four tornadoes occur in a three-week period.
This is:
In which
Then
0.1512 = 15.12% probability that fewer than four tornadoes occur in a three-week period.
Answer:
Step-by-step explanation:
Given
Required
Factorize
Rearrange
Group into three
Factorize the first bracket
Factorize the second bracket
x - 2y is a common factor of
So, the expression becomes
The expression cannot be further simplified;
<em>Hence, </em><em> is equivalent to </em><em></em>
Answer:
Either through decimals or finding common denominators.
Step-by-step explanation:
When you get decimals you can clearly see which is bigger and with common denominators, you can just cancel out the denominator and see which is bigger. If you'd like me to provide an example just let me know :)
