Sets can be written in various ways, including roster notation, set-builder notation, and interval notation. Roster notation lists all the elements of a set, such as ( A = {1, 2, 3} ). Set-builder notation describes the properties of the elements, like ( B = { x \mid x > 0 } ). Interval notation is often used for sets of numbers, such as ( C = (0, 5] ), indicating all numbers greater than 0 and up to 5.
Numbers greater than 0.7 are any real numbers that are larger than 0.7 on the number line. This includes decimals such as 0.8, 0.9, 1.0, as well as fractions like 3/4, 7/8, and integers like 1, 2, 3, and so on. In interval notation, the set of numbers greater than 0.7 can be represented as (0.7, ∞), where the parentheses indicate that 0.7 is not included in the set and the infinity symbol represents all numbers greater than 0.7.
The interval of 0 and 180 refers to the range of values between 0 and 180, inclusive. This interval can be represented in mathematical notation as [0, 180]. It includes all real numbers starting from 0 up to and including 180. This range is commonly used in various contexts, such as angles in geometry, where it represents a half-circle.
An interval in mathematics is a set of numbers that contains all numbers between any two numbers in the set. It can be represented on a number line as a continuous section between two points, often denoted in notation such as [a, b] for a closed interval (including endpoints a and b) or (a, b) for an open interval (excluding endpoints). Intervals can also be infinite, like (-∞, b) or (a, ∞). Visually, an interval appears as a line segment or ray depending on its type.
Between 3 and 3.1, there are infinitely many numbers, including decimals like 3.01, 3.05, and 3.09. These numbers represent values that are greater than 3 but less than 3.1. The interval can be expressed as (3, 3.1) in mathematical notation, indicating that it includes all real numbers within that range.
Interval notation is a method of writing down a set of numbers. An example of this is all numbers that are greater than five.Ê
The answer to this is 2, and 0.
It is (-3, 5].
(-3, 5] = {x : -3 < x ≤ 5}

In interval notation, the set of numbers greater than 0.7 can be represented as (0.7, ∞), where the parentheses indicate that 0.7 is not included in the set and the infinity symbol represents all numbers greater than 0.7.
Interval notation uses the symbols [ and ( to indicate closed an open intervals. The symbols can be mixed so that an interval can be open on one side and close on the other. Given two real numbers, a, b we can have (a,b) which is the interval notation for all numbers between a and b not including either one. [a,b) all numbers between a and b including a, but not b. (a,b] all numbers between a and b including b, but not a. [a,b] all number between a and b including a and b.
There is more than one notation, but the open interval between a and b is often written (a,b) and the closed interval is written [a,b] where a and b are real numbers. Intervals may be half open or half closed as well such as [a,b) or (a,b]. For all real numbers, it is (-infinity,+infinity), bit use the infinity symbol instead (an 8 on its side).
An interval that remains the same throughout a sequence
The real numbers between 1 and 6 form an interval on the number line. This interval is denoted as (1, 6), where the parentheses indicate that the endpoints 1 and 6 are not included. In interval notation, this set can be written as {x | 1 < x < 6}. This set includes all real numbers greater than 1 and less than 6.
