- 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.
Step-by-step explanation:
1) There are groups which are not represented in the survey like those who don't use web. And also those who take the time to write an online review are likely to do so because they are upset with the service they received.

Answer: 49
Step-by-step explanation:
If it's less than 100, that means that you can't use the number 100 in the answer. From 0 - 100 there are 50 even numbers (divisible by 2), so that means that there would be 50 - 1 even numbers between 0 and 100 (not including 100). 50 - 1 = 49

Answer:
x= -5
Step-by-step explanation:
let the number be x.
2x+5= -5 ====> equation
2x= -5-5. (shifted the +5 to the other side)
2x= -10
x= -10/2 ( shifted 2 on the other side as it was multiplying with x)
x= -5
