A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials

What is cardinality of 15?

The cardinality of 15 is equal to the number of elements in the set. Since 15 is only one number, its cardinality is 1.


How cardinality relates to the number of subsets of a set?

Cardinality is simply the number of elements of a given set. You can use the cardinality of a set to determine which elements will go into the subset. Every element in the subset must come from the cardinality of the original set. For example, a set may contain {a,b,c,d} which makes the cardinality 4. You can choose any of those elements to form a subset. Examples of subsets may be {a,c} {a, b, c} etc.


What are cardinality?

The cardinality of a finite set is the number of distinct elements in the set. For infinite sets, the cardinality is Aleph-Null if the elements of the set can be put into 1-to-1 relationship with the natural numbers: that is, if the set is countably infinite. However, the set of irrational numbers, for example, has a number of elements which is a greater order of infinity (uncountably infinite). It's cardinality is denoted by C, for "continuum".


What is the cardinality of set?

The cardinality of a finite set is the number of elements in the set. The cardinality of infinite sets is infinity but - if you really want to go into it - reflects a measure of the degree of infiniteness. So, for example, the cardinality of {1,2,3,4,5} is 5. The cardinality of integers or of rational numbers is infinity. The cardinality of irrational numbers or of all real numbers is also infinity. So far so good. But just as you thought it all made sense - including the infinite values - I will tell you that the cardinality of integers and rationals is aleph-null while that of irrationals or reals is a bigger infinity - aleph-one.


What equivalent set?

Two sets are equivalent if they have the same cardinality. For finite sets this means that they must have the same number of distinct elements. For infinite sets, equal cardinality means that there must be a one-to-one mapping from one set to the other. This can lead to some counter-intuitive results. For example, the cardinality of the set of integers is the same as the cardinality of the set of even integers although the second set is a proper subset of the first. The relevant mapping is x -> 2x.

What can you say about empty or null set?

It is a proper subset of every set other than itself. Its cardinality (size) is 0. It is unique (the only set with no elements).


How to program set Cardinality in C plus plus?

The cardinality of a set is simply the number of elements in the set. If the set is represented by an STL sequence container (such as std::array, std::vector, std::list or std::set), then the container's size() member function will return the cardinality. For example: std::vector<int> set {2,3,5,7,11,13}; size_t cardinality = set.size(); assert (cardinality == 6);


How does cardinality relates to the number of subsets in a set?

Assuming no restrictions on the set, the cardinality of a set, n, is related in this form # of subsets = 2n

What is the difference between a finite set and an infinite set?

Set A is a finite set if n(A) =0 (that is, A is the empty set) or n(A) is a natural number. A set whose cardinality is not 0 or a natural number is called an infinite set.
