Answer: stratified sampling and judgement sampling
Step-by-step explanation:
Stratified sampling is a probability method that is superior to random sampling because it reduces sampling error. A stratum is a subset of the population that share at least one common characteristic.
While
Judgment sampling is a nonprobability method. The researcher chooses the sample based on judgment. This is usually and extension of convenience sampling. For example, a researcher may decide to draw the entire sample from one "representative" city, even though the population includes all cities. When using this method, the researcher must be confident that the chosen sample is truly representative of the entire population.
Answer:
c) 30
Step-by-step explanation:
since the lines are parallel, 75° = 2x + 15°
this is because when two parallels lines are intersected by the same line, all respective angles are equal. Also, opposite angles on a line are equal too.
So now that u have 75 = 2x + 15, just solve for x by simplifying:
75 = 2x + 15
60 = 2x
30 = x
so the answer is c) 30
hope this helps!
Answer:
(D) $20,240
Step-by-step explanation:
Since the value of her car decreases by 8% every year, in one year it will be 92% of its original price ($22,000). 0.92 * 22,000 is 20,240. Therefore, the answer is D.
Hope this helps :)
Answer:

Step-by-step explanation:
Note that in programming, variables value can change, depending on the instructions of the programmer.
For example, if two values 10 and 20 are to be stored in a program and used.
The Programmer would do the following:
-
Create variables with symbolic names,
- Store the values in those two variables,
- Retrieve and use the stored values from the variables.
<em>A variable name could be like age, sex, salary, year 2020 etc.</em>
