Remark
The way this is written I would assume that it means 4*f(x) = x. That may not be entirely the correct assumption to be made.
Step One
Replace f(x) by 4f(x)
4*f(x) = x
Step two
Divide both steps by 4
f(x) = x/4 or (1/4)x
The slope is now 1/4
Discussion
A is incorrect.
The slope has been changed.
B is incorrect
The slope has been changed to 1/4 and the y intercept is still 0
C looks to be the right answer.
D The y intercept is still zero.
Comment
The question is a little hard to interpret. I've read it literally. That means that I have taken the question to mean that only f(x) was altered. If however, the right side was multiplied by 4 as well (as should be done), then the answer is A same slope same intercept. That's because the 4s on the left and right cancel, and the original equation results. I'm going to pick C but don't be surprised if it is A

Answer:
ok
Step-by-step explanation:
Answer:
a. Describing a sample with mean and standard deviation.
Step-by-step explanation:
Statistics can be categorized into descriptive and inferential statistics.
descriptive statistics uses data for descriptions through numerical analysis. It can be further divided in four parts.
- Measures of Central Tendency ( Mean, Median, and Mode)
- Measures of Frequency (Count, Percent, Frequency)
- Measures of Position (Percentile Ranks, Quartile Ranks.)
- Measures of Dispersion ( Range, Standard Deviation)
Inferential statistics however is based on assumptions and conclusions and generalizations drawn from samples or checks.
options b to d are all examples of inferential statistics while option a is an example of descriptive statistics.
