4. Capacity
• The maximum amount or
number that can be received
or contained; cubic contents;
volume:
– The bleachers are filled to
capacity.
– The gasoline tank has a
capacity of 20 gallons.
7. Composite Number
• A Composite Number can be divided evenly by numbers
other than 1 or itself.
– Example: 9 can be divided evenly by 1, 3 and 9.
– Example: 10 can be divided evenly by 1, 2, 5, and 10.
– All even numbers except 2 are composite numbers.
8. Congruent
• Exactly equal in size and shape.
• Congruent sides or segments have the exact same length.
• Congruent angles have the exact same measure.
These triangles are congruent.
Corresponding sides and angles
are congruent.
9. Diameter
• any straight line segment that passes through the
center of a circle and whose endpoints are on the
circle.
18. Lowest Terms
• A fraction that cannot be reduced.
• Also known as “simplest form”.
19. Mean
• the average of the numbers.
Example 1: What is the Mean of these numbers?
6, 11, 7
•Add the numbers: 6 + 11 + 7 = 24
•Divide by how many numbers (there are 3 numbers): 24 / 3 = 8
The Mean is 8
20. Median
• The middle number in a set of numbers when the
numbers are listed in order from smallest to largest.
To find the Median, place the numbers you are given in value order and find the middle
number.
Example:
Find the Median of {12, 3 and 5}
Put them in order: 3, 5, 12
The middle number is 5, so the median is 5.
Example:
There are fifteen numbers. Our middle number will be the eighth number:
3, 5, 7, 12, 13, 14, 21, 23, 23, 23, 23, 29, 39, 40, 56
The median value of this set of numbers is 23.
22. Mode
• The number that occurs most often in a set of
numbers.
To find the mode, or modal value, first put the numbers in order,
then count how many of each number.
Example:
3, 7, 5, 13, 20, 23, 39, 23, 40, 23, 14, 12, 56, 23, 29
In order these numbers are:
3, 5, 7, 12, 13, 14, 20, 23, 23, 23, 23, 29, 39, 40, 56
This makes it easy to see which numbers appear most often.
In this case the mode is 23.
