The universal set.
a population
Yes, it can. This happens when all of the observations are equal. This can also happen when some values are negative and some are positive (assuming that the variable under consideration can assume negative values).
The Elements, a book explaining all about the elements.
make a table as I did below for the set {a,b,c} with 3 elements. A table with all n elements will represent all the possible relations on that set of n elements. We can use the table to find all types of relations, transitive, symmetric etc. | a | b | c | --+---+---+---+ a | * | | | b | | * | | c | | | * | The total number of relations is 2^(n^2) because for each a or b we can include or not include it so there are 2 possibilities and there are n^2 elements so 2^(n^2) total relations. A relation is reflexive if contains all pairs of the form {x,x) for any x in the set. So this is the diagonal of your box. THESE ARE FIXED! No, in reflexive relation we still can decide to include or not include any of the other elements. So we have n diagonal elements that are fixed and we subtract that from n^2 so we have 2^(n^2-n) If you do the same thing for symmetric relations you will get 2^(n(n+1)/2). We get this by picking all the squares on the diagonal and all the ones above it too.
There are thirteen books in Euclid's Elements. You can read them all online at http://aleph0.clarku.edu/~djoyce/java/elements/elements.html .
A unit set contains all the elements under consideration.
A set containing all elements of a problem under consideration.
The universal set is the set of all possible elements under consideration. You can have a universal set of all people, or all bird species, or all numbers or whatever. You can even have a universal set of all people and all bird species and all numbers as one big set.
Name of the set which contains all elements is UNIVERSAL SET. It is usually represented by (U)
its affects people because of the gases it contains and also all the other elements its affects people because of the gases it contains and also all the other elements its affects people because of the gases it contains and also all the other elements its affects people because of the gases it contains and also all the other elements its affects people because of the gases it contains and also all the other elements its affects people because of the gases it contains and also all the other elements
The Periodic Table contains all the known elements and information about each of the elements, such as atomic number, atomic mass, group, period and symbol.
It contains a list of all known elements.
The complement of a set "A" is another set - call it "B" - that contains all the elements (of the universe under consideration) which are NOT in set "A". The "universe" must be specified (or implied), since concepts like the "set of all sets" are known to cause contradictions. For example, if the universe is all the people living in my country, and set "A" is all male people, then the "complement" would be the female people.
yes because it contains all organic elements
Sum(All elements in B) - Sum(All elements in A)
Jupiter contains the fewest heavy elements. Unlike other planets, Jupiter is a gas planet, and contains mostly light elements.
Disjoint means they have no elements in common. The union is the set of elements containing all elements from both sets. Since there is no overlap, the union will have 5+7 elements. Therefore the answer is 12.
