## What does an upside down V stand for?

raised to powerThe upside down ‘v’ used in the problem is called caret, and represents exponent, literally ‘raised to power’..

## What does AnB )’ mean?

Intersection The intersection of two sets A and B, written AnB, is the overlap of the two sets. … Empty set The empty set, written 0, is the set containing no elements.

## What does U mean in Algebra 2?

The set made by combining the elements of two sets. So the union of sets A and B is the set of elements in A, or B, or both. The symbol is a special “U” like this: ∪

## What does ∩ mean in math?

Definition of Intersection of Sets: Intersection of two given sets is the largest set which contains all the elements that are common to both the sets. … The symbol for denoting intersection of sets is ‘∩’.

## What does the upside down U mean in Venn diagrams?

The circles A and B represent sets. “Intersect” is represented by an upside down U. The intersection is where the circles overlap. “Union” is represented by a right-side up U. The union is the entire area of both circles.

## What is the U and upside down U in math?

Union and Intersection We just saw how to join two sets using “Union” (and the symbol ∪). There is also “Intersection” which means “has to be in both”. Think “where do they overlap?”. The Intersection symbol is an upside down “U” like this: ∩

## What does equal sign mean?

The symbol = Shows that what is on the left of the sign is exactly the same amount or value as what is on the right of the sign. Examples: 3 + 4 = 7 means that 3 + 4 is equal to 7.

## What is the U symbol in stats?

The symbol ‘μ’ represents the population mean.

## What does AUB mean?

union of the sets A and BDefinition 1. The union of the sets A and B, denoted by A U B, is the set that contains those elements that are either in A or in B, or in both. A U B = 1x | x ∈ A V x ∈ Bl. Definition 2. The intersection of the sets A and B, denoted by A n B, is the set containing those elements in both A and B.

## What do you mean if two or three circle intersect?

Answer: The intersections of two circles determine a line known as the radical line. If three circles mutually intersect in a single point, their point of intersection is the intersection of their pairwise radical lines, known as the radical center. douwdek0 and 7 more users found this answer helpful. Thanks 5.

## What do three equal lines mean?

A symbol with three horizontal line segments ( ) resembling the equals sign is used to denote both equality by definition (e.g., means is defined to be equal to ) and congruence (e.g., means 13 divided by 12 leaves a remainder of 1–a fact known to all readers of analog clocks).

## What are the three lines on a website called?

Insiders call it “the hamburger”: Three stacked lines, usually in the top left- or right-hand corner of a website, which people can click to see a menu of pages on the site.

## What does ø mean in Venn diagrams?

intersection is emptyWhile Venn diagrams are commonly used for set intersections, unions, and complements, they can also be used to show subsets. … That is, disjoint sets have no overlap; their intersection is empty. There is a special notation for this “empty set”, by the way: “Ø”.

## What is a backwards U in math?

In maths, the upside-down U means intersection of sets. … The ∩ symbol represents the intersection of two sets. This means the elements that are in common to both sets.

## What does the U mean in probability?

U(a,b) uniform distribution. equal probability in range a,b.

## What does triple bar mean?

The triple bar, ≡, is a symbol with multiple, context-dependent meanings. It has the appearance of a “=” sign with a third line. … In chemistry, the triple bar can be used to represent a triple bond between atoms. For example, HC≡CH is a common shorthand for acetylene.

## What does ∩ mean in probability?

The probability that Events A and B both occur is the probability of the intersection of A and B. The probability of the intersection of Events A and B is denoted by P(A ∩ B). If Events A and B are mutually exclusive, P(A ∩ B)
