1. In combinatorics, the "n!" symbol is used to calculate the number of possible arrangements of a set of items. For example, suppose you have a set of three letters: A, B, and C. To find the number of possible arrangements of these letters, you can use the "n!" symbol like this: 3! = 3 x 2 x 1 = 6. This means there are 6 possible ...Education.

Statistics is the study of the collection, analysis, interpretation, presentation, and organization of data. In other words, it is a mathematical discipline to collect, summarize data. Also, we can say that statistics is a branch of applied mathematics. However, there are two important and basic ideas involved in statistics; they are ...Consider “m, n and r” are three real numbers. Then the above properties can be described using m, n, and r as shown below: Commutative Property. If m and n are the numbers, then the general form will be m + n = n + m for addition and m.n = n.m for multiplication. Addition: m + n = n + m. For example, 5 + 3 = 3 + 5, 2 + 4 = 4 + 2.Oregon high school graduates won't have to prove basic mastery of reading, writing and math until at least 2029 after the state Board of Education voted unanimously to pause the requirement.If set A and set B are two sets, then A intersection B is the set that contains only the common elements between set A and set B. It is denoted as A ∩ B. Example: Set A = {1,2,3} and B = {4,5,6}, then A intersection B is: Since A and B do not have any elements in common, so their intersection will give null set.

Division gives us a quotient. In 15 ÷ 3 = 5, the quotient is five. Let us summarize the above four operations as: The general formula to calculate the mean is as follows: Mean = Sum of Given Data Total Number of Data M e a n = Sum of Given Data Total Number of Data. When using the Sigma (∑) notation, the mean formula is: ∑n i=1 Xi N ∑ i = 1 n X i N. Here, N = it is the Total number provided in a given data set.mathematics: [noun, plural in form but usually singular in construction] the science of numbers and their operations (see operation 5), interrelations, combinations, generalizations, and abstractions and of space (see 1space 7) configurations and their structure, measurement, transformations, and generalizations.The = equals symbol is used to show that the values on either side of it are the same. It is most commonly used to show the result of a calculation, for example 2 + 2 = 4, or in equations, such as 2 + 3 = 10 − 5. You may also come across other related symbols, although these are less common: ≠ means not equal. For example, 2 + 2 ≠ 5 - 2.
