Answer:
B) A random sample may represent the population <em>is your best answer.</em>
Step-by-step explanation:
Note that the answer choice says "may", which means that it doesn't <em>always</em> represent the population. Random samples means that they ask random people, and do not have a certain rule that they have to follow (such as recipients can only be a certain race, age, etc.) and that they can ask anybody they meet. This can give not only a higher chance of a general population's opinion, but also makes sure that there is not a high chance of obtaining misleading information.
For example, a random survey would not take place at a rally, in which most of the people would believe the same thing, and would answer fairly the same for the survey. Instead, a random survey may be taken at a busy intersection during the time when most people are out. You must note that though it has the best chance of getting a <em>more accurate</em> representation, it still isn't the most accurate. For the best accuracy, <em>everyone would have to answer the survey in which the survey question would affect</em>.

Fraction of square tiles = 
</h3><h3>
Fraction of rectangle tiles = 
</h3>
Step-by-step explanation:
Total number of tiles to be used in the kitchen = 100
The total number of square tiles = 34
The total number of rectangle tiles = 16
Now, calculating the total fraction of square tiles:
The fraction of square tiles = 
Also, solving the fraction, we get 
So, the decimal value of square tiles = 0.6
Calculating the total fraction of rectangle tiles:
The fraction of rectangle tiles = 
Also, solving the fraction, we get 
So, the decimal value of rectangle tiles = 0.34
The First One
The Third One
The Forth One
The others result in a lower number than what they are supposed to be. The 3 correct ones end with the exact number of the equations solution number.
-108=8x
Divide 8 on both sides
-13.5=x
The answer is...X=-13.5
