What is the base angle theorem?

The base angle theorem applies both to isosceles triangles, where two sides are congruent, and to equilateral triangles, where all three sides are congruent. While an equilateral triangle is symmetrical in all three directions, a triangle with only two congruent sides has only one axis of symmetry, which bisects both the noncongruent angle and the noncongruent side and divides the triangle into two congruent right triangles.

What is the purpose of statistics?

Statistics are used by marketing firms, companies that delve in the financial world, researchers, manufacturing organizations and government groups. Without statistics, the numerical information collected is useless. A goal of statistics is to find meaning in the provided data and determine what variations are meaningful and which ones occur merely by chance.

What angle is zero degrees?

Angles are measured in degrees ranging from zero to 360. A 360 degree angle starts at the point of inception and travels in a complete circle to once again reach the point of inception. This is why there are 360 degrees in one rotation. In math, the term "degree" is represented by a small circle appearing at the upper right corner of the number in question.

What is a bipartite graph?

These graphs are used in modeling relationships between two different classes of object. For instance, it is used to map the relationship in an affiliation network where new users are related to older ones. A graph is said to be bipartite if it does not contain an odd cycle, its chromatic number is equal to or less than two and its spectrum is symmetric.

How are polynomials used in everyday life?

The site points out that one common use of polynomials in everyday life is figuring out how much gas can be put in a car. If a person has a fixed amount of cash, such as $15, that person may do simple polynomial division, diving the $15 by the cost of each gallon of gas.\nAccording to iPracticeMath, a more advanced scenario would be determining how many shopping bags are necessary to accommodate items of similar shapes and sizes. This, too, uses polynomial division because the shopper must divide the number of items by an average number of items that can fit in the bag, rounding up to add a ba..

What is the way to multiply exponents with different bases?

An example of multiplying exponents with different bases is 3^2 * 4^2. Users should change the equation to read as (3 * 4)^2 which is equal to 12^2. To solve 12^2, users would multiply 12*12 which is equal to 144.When multiplying numbers where both the base and exponents are different, such as 2^2 * 3^3, each exponents has to be calculated first. In this equation, users would first calculate each part of the equation separately, 2^2 = 4 and 3^3=9 and then multiply 4 by 9 which equals 36. So 2^2 * 3^3 = 36.The process changes when two different negative exponents are involved as the exponents a..

What is a cumulative binomial table?

The easiest way to solve one type of binomial distribution problem is to look up the answer in a cumulative binomial table. Further, a cumulative binomial table isn’t just one table. It’s actually multiple tables that allow you to look up each value for the random variable in your problem. For example, in a coin-toss experiment using two coins, the problem asks what the probability is of getting one or fewer heads. The resulting cumulative binomial table lists all values for the probability that a toss results in no heads in addition to the probability that a toss results in one head. Unfo..

How do I find a percentage of a number?

Dictionary.com defines a percent as one-hundredth of a part. A percentage is how many hundredths of a part a given value is. When dividing the fraction of an amount by the whole amount, the answer results in a decimal. The first column to the right of the decimal is the tenths value, and the column to the right of that is the hundredths value.\nSince the answer to the question of percentage has the value of hundredths, multiplying by 100 brings hundredths into the ones column. For example, to determine the percentage value of 25 out of 100, first divide 25 by 100, resulting in 0.25. Multiply b..

What are some examples of common equations?

Each expression in an equation is made of varying number of terms or variables. Variables in an equation are unknown and the process of solving the equation is to find the variable’s value. In mathematics, there are many types of equations. The type of an equation determines the method of their examination.\nPolynomial equations, linear equations, parametric equations, Cartesian equations and differential equations are some of the many types of equations used in different branches of mathematics including algebra, arithmetic and geometry.\n(y = mx + b) is a linear equation’s common form. (..

What is a complement in math?

When trying to find the probability of something, all possible outcomes need to be determined. The outcomes are not what the problem solver wants to become the complement. For example, if May, June and July are the event, then January, February, March, April, August, September, October, November and December are the complement. They are not the months wanted but, when grouped with the months that are wanted, they represent all possible outcomes.
