Answer:
Of the 5000 surveys, 14% were returned. This response rate APPEARS to be low.
Step-by-step explanation:
Given:
Total sample collected = 5000
Survey returned = 700
i) What percentage of the 5000 surveys were returned?
To find percentage returned, we have:

Percentage returned = 14%
ii) Does that response rate appear to be low?
Yes, the response is significantly low as only 14% is returned out of expected 100%
iii) In general, what is a problem with a very low response rate?
The problem with in low response rate in general is that it causes the result to be biased as biased samples of those interested in a particular aspect may have been gotten.
Therefore, of the 5000 surveys, 14% were returned. This response rate APPEARS to be low.
It will be itself because 1 cannot be divided by the number itself
Answer:
37.5% Off
Step-by-step explanation:
Plugging in numbers to a calculator with a formula :)
You need to convert the cartesian coordinates to polar: This means we need to go from (x, y) --> (r, angle)
We can covert, using the following formulas:
Find r:



r = 4
Now, find our angle:
Use the inverse of tan

Turn 30 degrees to radian

= C
