We will be continuing our lessons on standard deviation with this video on understanding what a standard deviation value that we calculate really means; in other words, we're going to interpret standard deviation! First we'll take a look at what small and large deviations are. Then we will understand finding deviations above and below the mean. Finally, we'll look at a real-life example involving a range of student test scores from a class. Please like and subscribe.

We will be covering the remainder theorem to help us minimize the possible roots a polynomial has. We can use the coefficient of the leading term and the constant and create possible roots and then use synthetic division and trial and error to see which possible roots are ACTUAL roots. Then we can simplify our polynomial into a quadratic and find other irrational roots or use our graphing calculators. Please like, subscribe, hit the post-notification bell, comment, and share!

In this video we will be looking at the remainder theorem associated with polynomial division. It states that dividing a polynomial P(x) by a linear factor x - a for some number a and finding the remainder is equal to plugging a into P(x) to find P(a). We'll discuss it more in this video by reviewing synthetic division, the concept of the remainder theorem, and doing two practice problems.

In the last video, we looked at long division of polynomials, and today's video, we will be looking at an alternative form of polynomial division: synthetic division. We can use this shorthand, or shortcut, method when our divisor is linear. In this video, we will be comparing long division to synthetic division before doing one example and then diving into an application involving a shadow box.

Standard deviation is a measure of variation and tells us how distributed/spread out the data is from the mean using visuals such as a bell curve. In this video we'll simply be understanding some vocabulary, learn how to compute mean and standard deviation on the TI calculator, and do two hands-on practice problems with a switched webcam view of the calculator demo.

In this lesson, Anita will discuss what independent and dependent events, multiple events occurring simultaneously, and mutually exclusive events are. We'll cover mathematical formulas and look at a plethora of examples to master our understanding. Please like, subscribe, hit the post-notification bell, comment, and share!

We will be wrapping up logarithmic functions in this video dedicated to people who want to do some practice problems with Anita to prepare for assessments. Our first problem will be on graphing, the second on translations, and some more on rewriting in exponential form, inverses, and special cases.

Here is a welcome to our Algebra II course. The cheracteristics and chapters of this subject will be uncovered. Follow this Pinterest account for more updates on eCore!

In this lesson, we will be taking a look at the conjugate root theorem pertaining to finding the solutions of a polynomial. This theorem helps us determine irrational and imaginary roots to polynomials given that the polynomials meet certain criteria, such as having rational coefficients, etc. Watch for more information and three examples of different scenarios!

We will be wrapping up normal distributions in this video. Recall that normal distributions are symmetrical and natural bell curves representing that although data vary randomly from the mean, the frequency of data is higher as you approach the mean. After we review some basic characteristics of normal distributions, we will be diving into great examples, including a meal survey and test scores from a high school lecture class to prepare you for real-world applications.

Today we will be taking a look at normal distributions, which go hand-in-hand with standard deviation and is part of our study of statistics. In this video we will define standard distributions and look at a bell curve. We will also cover the empirical rule and take a look at an example involving female brown bears and their weights.
