1. What does the ordered pair (5,–6) represent on the Cartesian plane? Solution: The first element of (5, -6) = x-coordinate = 5 It is positive. It means that the horizontal distance of the point from origin is 5 units to the right. ...
Let X be the first coordinate of this ordered pair and let Y be the sum of its first and second coordinates. (i) Are the events " X=0′ " and " Y=0′′ independent? (ii) Are the random variables X and Y independent? (iii) What i...

Ordered pairAn ordered pair of two numbers, {eq}a\ and\ b {/eq}, is a pair {eq}(a,b) {/eq} that can not be equal to {eq}(b,a) {/eq} unless the value of {eq}a {/eq} is equal to {eq}b. {/eq} For example, if a ordered pair of (2,3) is never equal to...

A multiset is an ordered pair (𝑀,𝑓) where M is a set and f is a function from M to the nonnegative integers; for each 𝑚∈𝑀, 𝑓(𝑚) is said to be the multiplicity of m [37]. If M is a finite set, say {𝑚1,𝑚2,…,𝑚𝑟}, then a multiset (𝑀,𝑓...
Find the ordered pair for a system of equations. A simple way to solve a two-equation system is to try to eliminate one of the variable terms, add the two equations and then solve for both variables. For example, if you have two equations, 2x + 3y = 5 and x – y = 5, multiply...
What does happen to our goods when we order online and then return them? The reality is that much of it simply ends up in landfill (垃圾场). Each year, 5 billion pounds of waste is generated through returns in the world. In the US alone, customers return approximately 3.5 billion produc...
