11.5 Independent and Dependent Events
Identify whether events are independent or depdendent
Find the probability of independent and dependent events
Polynomial function
The document defines a polynomial function as a function of the form f(x) = anxn + an-1xn-1 +...+ a0, where n is a nonnegative integer and an, an-1,...a0 are real numbers with an ≠ 0. The degree of a polynomial is the highest exponent of its terms. Examples are provided to illustrate how to determine the degree and number of terms of polynomial functions. The document also asks questions to check understanding of identifying polynomial functions and determining their degree.
Independent and dependent events notes
1) Independent events are events where the outcome of one event does not affect the outcome of the next event. Dependent events are events where the outcome of the first event affects the probability of the outcome of the second event.
2) The probability of two independent events occurring is calculated by multiplying the individual probabilities. The probability of two dependent events occurring factors in how the first event affects the probability of the second.
3) Examples are provided to demonstrate calculating probabilities of independent and dependent events, such as spinning spinners or drawing marbles from a bag.
Probability of card

1) The document discusses permutations and combinations, which are ways of arranging or selecting items from a group.
2) A permutation is an arrangement of items that considers order, while a combination disregards order.
3) Formulas are provided to calculate the number of permutations and combinations for a given number of items selected from a larger set.
Combination
This document discusses two types of combinations: combinations with repetition and combinations without repetition. Combinations with repetition allow elements to be chosen multiple times from a set, while combinations without repetition do not allow repeats. It provides examples to illustrate each type, such as how many 2-letter words can be created from 4 letters with repetition (10 combinations) versus without repetition (6 combinations). The key difference between the two types is whether repetition of elements is allowed or not when selecting elements from a set.
Union and intersection
This document provides an introduction to union and intersection operations in SQL and Python. It explains that UNION combines results from multiple tables while avoiding duplicates, INTERSECT returns only matching rows, and EXCEPT returns rows that are not in the second table. Examples are shown using SQL queries on sample client and VIP tables, and using set operations in Python. Contact information is provided at the end for the mentoring organization that produced this document.

1.5 Quadratic Equations.pdf
This document provides instruction on factoring polynomials and quadratic equations. It begins by reviewing factoring techniques like finding the greatest common factor and factoring trinomials and binomials. Examples are provided to demonstrate the factoring methods. The document then discusses solving quadratic equations by factoring, putting the equation in standard form, and setting each factor equal to zero. An example problem demonstrates solving a quadratic equation through factoring. The document concludes by assigning homework and an optional reading for the next class.

2.2 More on Functions and Their Graphs
This document discusses functions and their graphs. It defines increasing, decreasing and constant functions based on how the function values change as the input increases. Relative maxima and minima are points where a function changes from increasing to decreasing. Symmetry of functions is classified by the y-axis, x-axis and origin. Even functions are symmetric about the y-axis, odd functions are symmetric about the origin. Piecewise functions have different definitions over different intervals.
1.6 Other Types of Equations
This document provides examples and steps for solving various types of equations beyond linear equations, including:
1) Polynomial equations solved by factoring
2) Equations with radicals where radicals are eliminated by raising both sides to a power
3) Equations with rational exponents where both sides are raised to the reciprocal power
4) Equations quadratic in form where an algebraic substitution is made to transform into a quadratic equation
5) Absolute value equations where both positive and negative solutions must be considered.
1.5 Quadratic Equations (Review)
This document provides instruction on factoring quadratic equations. It begins by reviewing factoring polynomials and trinomials. It then discusses factoring binomials using difference of squares, sum/difference of cubes, and other patterns. Finally, it explains that a quadratic equation can be solved by factoring if it can be written as a product of two linear factors. An example demonstrates factoring a quadratic equation by finding the two values that make each factor equal to zero.
2.1 Basics of Functions and Their Graphs
This document provides an overview of functions and their graphs. It defines what constitutes a function, discusses domain and range, and how to identify functions using the vertical line test. Key points covered include:
- A function is a relation where each input has a single, unique output
- The domain is the set of inputs and the range is the set of outputs
- Functions can be represented by ordered pairs, graphs, or equations
- The vertical line test identifies functions as those where a vertical line intersects the graph at most once
- Intercepts occur where the graph crosses the x or y-axis
9.6 Binomial Theorem
The document discusses the binomial theorem, which provides a formula for expanding binomial expressions of the form (a + b)^n. It gives the formula for finding the coefficient of the term containing b^r as nCr. Several examples are worked out applying the binomial theorem to expand binomial expressions and find specific terms. Factorial notation is introduced for writing the coefficients. The document also discusses using calculators and Desmos to evaluate binomial coefficients. Practice problems are assigned from previous sections.
13.3 Venn Diagrams & Two-Way Tables
The document discusses using Venn diagrams and two-way tables to organize data and calculate probabilities. It provides examples of completing Venn diagrams and two-way tables based on survey data about students' activities. It then uses the tables and diagrams to calculate probabilities of different outcomes. The examples illustrate how to set up and use these visual representations of categorical data.

A Visual Guide to 1 Samuel | A Tale of Two Hearts
These slides walk through the story of 1 Samuel. Samuel is the last judge of Israel. The people reject God and want a king. Saul is anointed as the first king, but he is not a good king. David, the shepherd boy is anointed and Saul is envious of him. David shows honor while Saul continues to self destruct.
