Answer:
There is a 93.28% probability that one cubic meter of discharge contains at least 6 organisms.
Step-by-step explanation:
The number of organisms in a cubic meter of discharge is a Poisson process. So, we use the following definition:
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
is the Euler number
is the mean in the given time interval.
Organisms are present in ballast water discharged from a ship according to a Poisson process with a concentration of 10 organisms/m3. This means that
What is the probability that one cubic meter of discharge contains at least 6 organisms?
This is . We know that either we have less than 6 organisms, or we have at least 6 organism. The sum of the probabilities is decimal 1. So
In which
.
Each one of these probabilities can be found by the poisson formula.
So
So
Finally
There is a 93.28% probability that one cubic meter of discharge contains at least 6 organisms.
Answer:
A = a + b 2 h this is the answer
He used 11 quarts out or 3 gallons .
I know because in 1 <span>gallon</span> there are 4 quarts .
You do 4*3 =12.
Than you -1 from 12 and get 11.
So,Your answer is He used 11 quarts out of 3 gallons.
Hope that helped.
