SHMS 7th Grade Math Powertime Vocab 4

Cross-section A plane figure obtained by slicing a solid with a plane.
Irregular Polygon A polygon with sides not equal and/or angles not equal.
Parallel Lines Two lines that lie in the same plane and do not intersect. AB || CD denotes this relationship between line AB and line CD.
Pi The relationship of the circle’s circumference to its diameter, when used in calculations, it is typically approximated as 3.14; the relationship between the circumference (C) and diameter (d), c/d or 3.14
Regular Polygon A polygon with all sides equal (equilateral) and all angles equal (equiangular).
Supplementary Angle Two angles whose sum is 180 degrees.
Vertical Angles Two nonadjacent angles formed by intersecting lines or segments. Also called opposite angles.
Probability A measure of the likelihood of an event. It is the ratio of the number of ways a certain event can occur to the number of possible outcomes.
Probability Model It provides a probability for each possible non-overlapping outcome for a change process so that the total probability over all such outcomes is unity. This can be either theoretical or experimental.
Sample space All possible outcomes of a given experiment.
Simple Event Any event which consists of a single outcome in the sample space. It can be represented by a single branch of a tree diagram.
Simulation A technique used for answering real-world questions or making decisions in complex situations where an element of chance is involved.
Theoretical Probability The mathematical calculation that an event will happen in theory. It is based on the structure of the processes and its outcomes.
Tree diagram A tree-shaped diagram that illustrates sequentially the possible outcomes of a given event.
Chance Process The repeated observations of random outcomes of a given event.
Compound Event Any event which consists of more than one outcome.
Event Any possible outcome of an experiment in probability. Any collection of outcomes of an experiment. Formally, it is any subset of the sample space.
Experimental Probability The ratio of the number of times an outcome occurs to the total amount of trials performed.
Independent events Two events when the occurrence of one of the events gives us no information about whether or not the other event will occur; that is, the events have no influence on each other.
