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.
Answer:
Multiplication property of equality
Step-by-step explanation:
Given
Step 4: b = -27/8
Required
Which property justifies it?
First, it should be noted that step 4 is a result of step 3
When step 3 is multiplied by 3/8 on both sides, we have step 4;
i.e.
<em>The property that allows 3/8 be multiplied on both sides is referred to as the multiplication property of equality</em>
Answer:
7 9. If you have any fractions, get rid of those first by multiplying ALL ... to model and solve 3n 6 15. Then solve the equation. 10. 13 x = 32 + 5 x 3.
Step-by-step explanation:
Answer:
22,500 =2p
Step-by-step explanation:
Because the price of the new car is the price of the old car times 2.
22,500 =2p
First you get P alone. P is being multiplied by 2 so you divide it by 2 so it cancels out.
11250 = p
When you do something to one side of the equation you do the same to the other side so they are still equal to each other.
