Part A)
The answer is b) this is qualitative because the responses are about whether people are satisfied or not, instead of something numeric.
Part B)
The answer is b) this is random because it represents a different person in the sample, and it is variable because people feel differently about their situations.
I divided 315 by any random number and chose the one that gave me a whole number
So I got

x
Part A: 1 7/9
Part B: ????
Sorry I don't get it
Answer:
Step-by-step explanation:
The pythagorean theorem goes: a^2 + b^2 = c^2
c is the hypotenuse of the right triangle, the longest side.
This means that by squaring the two shorter sides of an answer choice and seeing if they are equal to the longest side squared we can see if that answer choice contains the sides of a right triangle.
So, for example, lets look at answer choice B. 4.5^2 + 3^2 = 29.25 and 7.5^ = 56.25
29.25 is not equal to 56.25 so B is incorrect.
Doing the same process with answer choice A gets us: 6^2 + 2.5^2 = 42.25 and 6.5^2 = 42.25
This means a^2 + b^2 equals c^2 and answer choice A is our correct answer.
