## 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.

## What does A and B stand for in math?

View this answer. A and B in algebra stand for any variables of real numbers. A real number is a value of a continuous quantity that can represent a distance along a…

## 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 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 SX mean in stats?

standard deviationI know that sx is the standard deviation of a sample and σx is the standard deviation of a population.

## What is the upside down U in probability?

Upside down U in venn diagrams is known as “intersection”. … probability wise upside down ‘U’ stands (A∩B) for A intersection of B means elements from both sets indicates are common from set A as well as set B.

## What does U mean in logic?

top, truth. propositional logic, Boolean algebra. The statement ⊤ is unconditionally true. A ⇒ ⊤ is always true. U+22A4.

## What does C mean in stats?

P(AB) means the probability that events A and B occur. You could write it P(A∩B). The superscript c means “complement” and Ac means all outcomes not in A. … The complement of an event is the subset of outcomes in the sample space that are not in the event. A complement is itself an event.

## What is P A and B?

p(A and B) = p(A) x p(B). In other words, the probability of A and B both occurring is the product of the probability of A and the probability of B. What is the probability that a fair coin will come up with heads twice in a row? Two events must occur: a head on the first toss and a head on the second toss.

## What does U mean in math?

∪ The symbol ∪ means union. Given two sets S and T, S ∪ T is used to denote the set {x|x ∈ S or x ∈ T}. For example {1,2,3}∪{3,4,5} = {1,2,3,4,5}. ∩ The symbol ∩ means intersection.

## 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)

## What does the U mean in Venn diagrams?

The union of two sets is represented by ∪. (Don’t confuse this symbol with the letter “u.”) This is a two-circle Venn diagram. The green circle is A, and the blue circle is B. The complete Venn diagram represents the union of A and B, or A ∪ B.

## What is the OR rule?

Sometimes we want to know the probability of getting one result or another. The OR rule can help us here if the two results are mutually exclusive. Mutually exclusive means that the two outcomes of the same event cannot happen at the same time. = P(A) + P(B) for mutually exclusive events. …

## What does a ∩ b )’ mean?

In mathematics, the intersection of two sets A and B, denoted by A ∩ B, is the set containing all elements of A that also belong to B (or equivalently, all elements of B that also belong to A).

## What does the U mean in stats?

The term population mean, which is the average score of the population on a given variable, is represented by: μ = ( Σ Xi ) / N. The symbol ‘μ’ represents the population mean. The symbol ‘Σ Xi’ represents the sum of all scores present in the population (say, in this case) X1 X2 X3 and so on.

## What does the math symbol mean?

< Less Than and > Greater Than. … This symbol > means greater than, for example 4 > 2. ≤ ≥ These symbols mean ‘less than or equal to’ and ‘greater than or equal to’ and are commonly used in algebra.

## What does U and upside down U mean in math?

Union and Intersection 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: ∩
