Answer:
The sampling used is simple random sampling.
Step-by-step explanation:
Consider the provided information.
Types:
- Simple random sample is a subset of the population chosen from a larger set. Every person is selected by chance and randomly.
- Systematic sampling: list of elements is counted off.
- Convenience sampling: data which is readily available is used. That is, the first people are running into by the surveyor.
- Cluster sampling: divide the population into groups, usually geographically.
- Stratified sampling: divide population into groups called strata. but this time population might be separated into males and females.
Here, randomly selected 60 customers, Thus, the sampling used is simple random sampling.
Over estimated because the exact answer is 2.6.
There are 5 hamsters. If she has 6 fewer hamsters than fish, that means x-6=5
which means 5+6=11 so there are 11 fish.
The answer is 11
To get the
Mean, you have to add all the ages of the men together:
Next you divide
by the amount of people:
Final Answer: 26
Answer:
Prime
Step-by-step explanation:
This expression is actually impossible to factor. To get rid of the middle term, you would need two equal and opposite x values, such as in (x+4y)(x-4y). However, in that case, the expanded expression would be x^2-16y^2, not plus. If you go for the first option, then you are left with a middle term, such as 8xy. Therefore, this expression is prime. Hope this helps!
