Answer: c. 50
Step-by-step explanation:
1. By definition, when you add the exterior angles of a regular polygon, you obtain 360 degrees and the number of sides of that polygon can be calculated by dividing 360 degrees by the measure of the exterior angle of it.
2. As you know, the number of sides cannot be fractions, therefore, if you make the folllowing division:
360°/50°=36/5
You obtain a fraction.
3. Then, an exterior angle of a regular polygon cannot have the measure is 50°.

A student wants to find the answer to the question “What is the most popular restaurant in Bedford?” He asks 20 randomly selected customers at one local restaurant. Which best describes the accuracy of the results of the survey?
The survey results will be accurate since the sample was chosen randomly.
The survey results will be inaccurate since the entire population should have been surveyed.
The survey results will be inaccurate since the entire sample of the population was eating at the same restaurant.
The survey results will be accurate since the sample represents the population and the population is the target of the survey.
<u>Option C</u>
The survey results will be inaccurate since the entire sample of the population was eating at the same restaurant best describes the accuracy of the results of the survey
<h3><u>
Explanation:</u></h3>
In a statistical study, sampling methods relate to how we choose members from the population to be in the research. If a sample isn't randomly chosen, it will reasonably be biased in some way and the data may not be representational of the population.
Efficient interpretation of data is based on real procedures for generating data and sensitive analysis of the data.The efficiency depends on how strongly the sample outlines the population. The sample must contain the attributes of the population to be representative. Here sample is chosen from one local restaurant so it willnot produce efficient analysis result.
Answer:
x < y
Step-by-step explanation:
Bobby has 24 pizza slices
he divided them among his friends and each friend got 3 pieces
how many friends did he have
so
24 divided by number of friends=3
24/y=3
multiply both sides by y
24y/y=3y
24 times y/y=3y
24 times 1=3y
24=3y
divide both sides by 3
24/3=3y/3
8=3/3y
8=1y
y=8
8 friends
80 oz and 5 lbs are the same
