Example Question #11 : Mathematics
A square has area 196 square feet. Give its perimeter.
112 feet
49 feet
14 feet
56 feet
28 feet
56 feet
The area of the square is equal to the length of a side multiplied by itself. Thus, the length of a side is equal to the square root of 196. Since

If 
If 
first by substituting 18 for 
then by dividing both sides by 18 to isolate the 
Now, in the other equation, substitute 4 for 
Divide both sides by 4 to isolate the 
the correct choice.

Which of the following equations does not describe a line through the point 
If the line of an equation passes through 
True
True
True
True
False
The correct choice is

What value of 
Isolate the 
Multiplication precedes subtraction in the order of operations, so reverse the subtraction of 12 by adding 12 to both sides:
Now reverse multiplication by 2 by dividing by 2:
Example Question #1 : Knowledge Of Probability, Statistics, And Data Interpretation
What is the likelihood, expressed as a percentage, of rolling 2 straight 2s using one 6-sided dice?
3%
8.5%
5%
17%
3%
The likelihood of rolling any given number on a 6-sided dice is 16.6%, to get the likelihood of that even happening twice in a row, simply multiply 16.6% by itself, to get 2.7%, rounded up to 3%
Example Question #1 : Knowledge Of Probability, Statistics, And Data Interpretation
A set of ten scores has mean 30.
Nine of the scores are given below, with the circle representing the tenth.
What is the tenth score?
The mean of a group of scores 
Set 
Multiply both sides by 10 to reverse division by 10:
The sum of the scores must be 300. Add the known scores:
Subtract this sum from 300:
the missing tenth score.
