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:
17 13/24 cups of sugar
Step-by-step explanation:
Muffins = 5 3/8 cups of sugar
Brownies = 4 2/3 cups of sugar
Cookies = 7 1/2 cups of sugar
Total cups of sugar used = Muffins + Brownies + Cookies
= 5 3/8 + 4 2/3 + 7 1/2
= 43/8 + 14/3 + 15/2
= 129+112+180/24
= 421 / 24
= 17 13/24 cups of sugar
Equivalent to 17.5417 cups of sugar
Approximately about 18 cups of sugar to an whole number

Answer:
sound energy
One type is sound energy. Sound energy is defined as the energy of vibrating molecules. Sound energy works by pushing and pulling molecules. Typically, speakers push and pull the air around us which is why we can hear a TV or a radio.
