Explanation of Coefficients:
In mathematics, a coefficient is a numerical or constant factor in a term of an algebraic expression. It is the number that is being multiplied by a variable. For example, in the expression 5x, the coefficient is 5, and in the expression -3y, the coefficient is -3.
Study Guide for Coefficients:
- Definition: A coefficient is the numerical factor in a term of an algebraic expression.
- Identifying Coefficients: Look for the number being multiplied by a variable in an algebraic expression.
- Examples:
- In the expression 4x, the coefficient is 4.
- In the expression -2y, the coefficient is -2.
- In the expression 3xy, the coefficient is 3.
- Operations with Coefficients: Coefficients can be added, subtracted, multiplied, and divided just like regular numbers.
- Solving Equations: Coefficients are crucial for solving equations and isolating variables.
- Practice Problems: Practice simplifying algebraic expressions by identifying and working with coefficients.

DATA ANALYSIS, STATISTICS, AND PROBABILITY
Understand that, just as with simple events, the probability of a compound event is the fraction of outcomes in the sample space for which the compound event occurs. Understand and use appropriate terminology to describe independent, dependent, complementary, and mutually exclusive events.
For events with a large number of outcomes, understand the use of the multiplication counting principle. Develop the multiplication counting principle and apply it to situations with a large number of outcomes.
