Answer:

Step-by-step explanation:
The total amount of shrimp that was eaten was 12 pieces of shrimp.
To make the fraction you will simply put the amount of shrimp Jeremy ate over the total number of shrimp eaten by the pair.
Therefore, the fraction would look like this:

The decimal form of this would be 0.4167. Which also means that Jeremy ate 41.67% of the total amount of shrimp eaten.
Hope this helps!!
Answer:
0.67% probability he will have to shut down after this month
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.
On average sells 8.9 machines per month.
So 
Using the Poisson distribution, what is the probability he will have to shut down after this month
If he sells less than 3 machines.






0.67% probability he will have to shut down after this month
3 to the power of 9 over 10
What's the problem?

Answer: Cluster sampling
Step-by-step explanation:
Cluster sampling is a type of sampling method . With cluster sampling, the observer splits the population into separate groups which are called as called clusters. After dividing the whole populations into clusters he select a simple random sample of clusters from the population. The observer conducts his analysis on data from the sampled clusters.
From the given statement we can see that the automobile is doing his analysis by selecting three stores from each state (cluster) in the country and surveys all customers present in the store in a certain week.
Hence, he used cluster sampling .
