Symbols for sets of numbers

But the set {2, 4} is not an element of the set D, because the four elements of the set D are all numbers (D does not have any sets as elements), so it is incorrect to write {2, 4} ∈ D. On the other hand, the number 2 is an element of D , so it is correct to write 2 ∈ D ; but the number 2 is not a subset of D (because the number 2 is a ...

In Maths, an average of a list of data is the expression of the central value of a set of data. Mathematically, it is defined as the ratio of summation of all the data to the number of units present in the list. In terms of statistics, the average of a given set of numerical data is also called mean. For example, the average of 2, 3 and 4 is (2 ...In statistics, the mode is the value that is repeatedly occurring in a given set. We can also say that the value or number in a data set, which has a high frequency or appears more frequently, is called mode or modal value. It is one of the three measures of central tendency, apart from mean and median. For example, the mode of the set {3, 7, 8 ...21 de jan. de 2007 ... ... number), and the symbolism of the fact that one can traverse a given curve infinitely often. 2. Page 3.
