5th Six Weeks Flashcards
Moving a shape so that it is in a different position, but still has the same size, area, angles and line lengths.
Transformation
Moving a shape, without rotating or flipping it “Sliding”
Translation
An image or shape as it would be seen in a mirror. “Flip”
Reflection
When there is a central point that stays fixed and everything else moves around that point in a circle. “Turn”
Rotation
To resize something or to make it larger or smaller.
Dilation
The likelihood of the occurrence of a particular event.
Chance
All other outcomes that are NOT the event.
Complement of an Event
When there are x ways to do one thing, and y ways to do another, then there are x times y ways of doing both.
Counting Principle
All outcomes are equally likely.
Fairness
The chance that something will happen; how likely it is that some event will happen.
Probability
All the possible outcomes of an experiment.
Sample Space
The ratio of the number of times an event occurs to the total number of trials or times the activity is performed.
Experimental Probability
Probability based on reasoning written as a ratio of the number of favorable outcomes to the number of possible outcomes.
Theoretical Probability
A plane spanned by the x-axis and y-axis in which the coordinates of a point are its distances from two intersecting perpendicular axes.
Coordinate Plane
The line on a graph that runs horizontally (left-right) through zero.
X axis
Y-axis
The line on a graph that runs vertically (up-down) through zero.
Origin
The starting point which is (0,0) on a coordinate plane.
Ordered Pair
Two numbers written in a certain order that are usually written in parentheses.
Quadrant
Any of the 4 equal areas made by dividing a plane by an x- axis and y-axis. They are usually numbered I, II, III and IV.
Volume
The amount of 3-dimensional space an object occupies.
Dimensions
A measurement of length in one direction.
Prism
A solid object that has two identical ends and all flat sides.
Cylinder
A solid object with two identical flat ends that are circular or elliptical and one curved side.
Central tendency
Measure that tells us where the middle of a group of data lies.
Mean
The average of the numbers.
Median
The middle number in a sorted list of the numbers.
Mode
The number that appears most often in a set of numbers.
Range
The difference between the lowest and highest values.
Graphs
A diagram of values, usually shown as lines or bars.
Data
A collection of facts, such as values or measurements.
Circle graph
A graph that is made by dividing a circle into sections or categories. It allows for comparison of the part to the whole.
Line graph
A graph made of points connected by lines. This type of graph is used to show change over time.
Bar graph
A graph made of rectangles that represent the quantities or numbers of the different categories.
Line Plot
Shows data on a number line with x or other marks to show frequency.
Steam-Leaf Plot
A plot where each data value is split into a "leaf" (usually the last digit) and a "stem" (the other digits).
Ex:
STEM LEAF
1 3 4 = 13 & 14
12 1 3 6 = 121, 123, & 126
