A conditional statement is a statement that can be written in the form “If P then Q ,” where P and Q are sentences. For this conditional statement, P is called the hypothesis and Q is called the conclusion. Intuitively, “If P then Q ” means that Q must be true whenever P is true. Mean: The "average" number; found by adding all data points and dividing by the number of data points. Example: The mean of 4 , 1 , and 7 is ( 4 + 1 + 7) / 3 = 12 / 3 = 4 . Median: The middle number; found by ordering all data points and picking out the one in the middle (or if there are two middle numbers, taking the mean of those two numbers).The statement “ p implies q ” means that if p is true, then q must also be true. Statement p is called the premise of the implication and q is called the conclusion. Was this answer helpful? By definition, this means that x + y ∈ Q and xy ∈ Q as required.

For example, the mode of the set {3, 7, 8 ...Symbol Description Location \( P, Q, R, S, \ldots \) propositional (sentential) variables: Paragraph \(\wedge\) logical “and” (conjunction) Item \(\vee\) Writing {\displaystyle x\in A} x\in A means that "x is an element of A". Equivalent expressions are "x is a member of A", "x belongs to A", "x is in A" and "x lies in A". The expressions "A includes x" and "A contains x" are also used to mean set membership, however some authors use them to mean instead "x is a subset of A".This means that the provided number cannot be written as {eq}\bar{4} {/eq}, because that would suggest that the number four goes on indefinitely, thus distorting the meaning of the number 444.Learn the definition of an integer. Identify integers and non-integers with examples. Understand how sets of integers are used in math and what they look like.t. e. In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. [1] The set X is called the domain of the function [2] and the set Y is called the codomain of the function. [3] Functions were originally the idealization of how a varying quantity depends on another quantity. In Maths, an intercept is a point on the y-axis, through which the slope of the line passes. It is the y-coordinate of a point where a straight line or a curve intersects the y-axis. This is represented when we write the equation for a line, y = mx+c, where m is slope and c is the y-intercept.. There are basically two intercepts, x-intercept and y-intercept.6. The mathematician R.L. Moore, who was very careful with his language, interpreted "only if" to mean "if and only if". In his mind, "A only if B" was a stronger statement than "A if B". In other words, "A only if B" tells us that "A if B", but also gives us a little extra information: "A only if B".Secant, cosecant and cotangent, almost always written as sec, cosec and cot are trigonometric functions like sin, cos and tan. sec x = 1. cos x. cosec x = 1. sin x. cot x = 1 = cos x. tan x sin x.
