<u>Full question:</u>
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.
There are 540 fuses in total and the original price of the internet is $55.91
<h3>
How to work with percentages?</h3>
a) We know that 5% of the fuses are faulty, and there are 27 faulty fusses, then we can write:
5% = 27
100% = x
We want to find x, to do that, we can write:
x = 27*(100%/5%) = 27*20 = 540
There are 540 fuses in total.
b) Now we know that the original price is P, and when we decrease it by 7%, then new price is $52.00
Then we can write:
$52.00 = P*(1 - 7%/100%)
$52.00 = P*(0.93)
$52.00/0.93 = P = $55.91
The original price is $55.91

no
you can't have two of the same numbers
Step-by-step explanation:
Triangle 1 can have 30°, 75° and 75° angles whereas Triangle 2 can have 30°, 30° and 120° angles.
Since they do not have all 3 congruent angles, they are not similar.
The decimal for 8/18 is 0.44, you simplify 8/18 to 4/9, divide 4 by 9 for the decimal.
