Answer:
- This is a biased sampling method for obtaining customer opinions because those who take the time to write an online review are likely to do so because they are upset with the service they received.
- The direction of the bias is likely to overestimate the proportion of customers who have a negative opinion on the service.

Answer:
x = 14.5
Step-by-step explanation:
This is a supplementary angle, meaning the sum of the angles is 180°.
We can find the value of x by combining like terms.
5x - 6 + 7x + 12 = 180.
5x and 7x are alike.
5x + 7x = 12x.
-6 + 12 = 6.
The final equation is 12x + 6 = 180.
We can solve this by subtracting 6 from 180.
180 - 6 = 174.
12x = 174
Lastly, we divide 174 by 12.
174 / 12 = 14.5
Therefore, x is equal to 14.5
A: 25x(1-0.1)=22.5
B: 27x(1-0.2)=21.6
C: 26x(1-0.15)=22.1
Answer: Store B (lowest price), store C and store A (highest price).
