Answer:
The correct option is D. No, because a random sample from all customers of the shopping mall was not selected
Step-by-step explanation:
In statistics, Bias can be described as a term which depicts error if a sample is not taken evenly or it depicts errors taken from an unjust sampling.
In statistics, sampling bias means the errors which occur if one part of the population is favoured more then the rest of the populations. In this kind of bias, the individuals for experimentation are not chosen randomly.
As the customer satisfaction survey was distributed in only one of the gates hence, it does not give a generalized result and the result is biased.
Divide until you get one moth alone then multiply then simplify if you don't know how to simplify please pm me.
Answer:
Step-by-step explanation:
The open circle means that the point is not included in the solution set, and the arrow pointing left means that all numbers less than -2 are members.
In set-builder notation, each term has a special meaning. The braces enclose the members of the set.
Here's how you translate the notation,
7x - 1 = 5x - 8
Minus 5x on each side
2x -1 = -8
Plus 1 on each side
2x = -7
Divide by 2 on each side
x = -7/2
The number is most likely -7/2
Polygon area = [circumradius^2 * # sides * sine (360/# sides)] / 2
small hexagon area =[5^2 * 6 * sine (60)] / 2
