The mean of a finite set S of numbers is 14, the median of this set of numbers is 12, and the standard deviation is 1.8. A new set T is formed by muliplying each member of the set S by 3. Which of the following statements must be true of the set T? ()I. The mean of the...
The concept of cardinality is a generalization of the concept of number of elements in a finite set. The cardinalities of sets do only half the work of the natural numbers. However, the cardinality tells nothing about the order of the elements. And even though the set of natural numbers ...
A unit set contains only one element. Two sets are equal only if they contain exactly the same elements. Cardinality: The cardinality of the empty set is zero. The cardinality of an infinite set is infinite. Two sets have the same cardinality if there is a one-to-one mapping between ...
