Example Question #34 : Other Data Calculations
For a formal dinner that he is planning, James needs to choose among different appetizers, main courses, and desserts. If the dinner has to have of each, how many possible combinations can James choose?
In order to find the total number of possibilities, we will need to multiply the number of choices together. Since we have appetizers, main courses, and desserts, we can write the following to find the number of total possibilities:
There are total possibilities for the three-course dinner.
Example Question #202 : Statistics
A basketball coach is trying to name a captain, a co-captain, and then a team manager from a pool of students. If each student can only hold one post, how many different ways can the coach pick these three positions?
Starting with the captain, the coach will have total choices.
Since the coach will have chosen the captain, there are total choices for co-captain.
Afterwards, the coach will only have total choices for the team manager.
Thus, multiply these numbers together to get the total number of combinations possible for these three positions.
Example Question #204 : Calculations
The sales of a construction supply company are shown for the first six months of a year:
What is the percent change in sales between March and April?
Start by finding the amount that the sales increased from March to April.
To find the percent change, divide the amount increased by the original value from March, then multiply the value by .
Sales increased by .

Example Question #1 : Patterns And Sequences
What property of arithmetic is symbolized below?
If , then
Symmetric
Commutative
Associative
Reflexive
Symmetric
The symbols show that if one number is equal to another, the equality holds no matter the order of the two. This is the symmetric property of equality.
Example Question #161 : Numbers
What property of arithmetic is symbolized below?
Reflexive
Identity
Transitive
Commutative
Reflexive
The symbols express the idea that any number is equal to itself. This is the reflexive property of equality.
Example Question #3 : Patterns And Sequences
What property of arithmetic is symbolized below?
Transitive
Associative
Commutative
Symmetric
Associative
The symbols express the idea that if three numbers are added, the same sum results regardless of which numbers are added first. This is the associative property of addition.
