Mr. Ravenhead's car averages 23.75 miles per gallon of gasoline. Express this amount as a mixed number in simplest form
lisabon 2012 [21]
A mixed number consists of a whole number and a fraction.

23.7523 will be the whole number.
0.75 will be the fraction.

To convert 0.75 into a fraction, set it over 100 and simplify.

\frac{75}{100} = \frac{75:25}{100:25} = \frac{3}{4}

23 \frac{3}{4}

Explain how you know 21/100 is greater than 1/5
Nataly_w [17]

This problem can be solved using equivalent fractions. The first step in resolving this problem is to realize that fractions are best compared when they both have the same denominator.  In this case, I will choose to make that common denominator 100. There is no need to rewrite the fraction \frac{21}{100} as the denominator for this fraction is already 100. The fraction \frac{1}{5} =\frac{20}{100} . This is achieved by multiplying both the numerator and denominator by 20. Now that the two fractions have the same denominator, we can easily see that \frac{21}{100} is greater than \frac{1}{5} because it is greater than its equivalent fraction.

As part of a statistics project, Andrea would like to collect data on household size in her city. To do so, she asks each person
strojnjashka [21]

Answer:

Charlie did not use any randomization; he took a convenience sample.

Step-by-step explanation:

The first question we need ask is whether his classmates make up the population of the city? Or does it mean that his classmate will give unbiased representation of the entire city? Because we are certain there are many other schools within the city of interest. Less assume he can do that, what will happen to all other schools? These are many other factors rendered his choice of sampling inappropriate for this study.

Therefore, the process is not random but convenience sample, even though they might give information about their various household sizes, it might not give the true picture of the city he is trying to investigate.

The best approach should have been a probability sampling techniques, preferably a systematic random sampling approach. If he has followed this process of sample selection, it will give a more reliable and well representative sample to determine the households size in the city of his interest.
