 An equivalence relation 2009-04-22 syed pose la question :D is the relation defined on Z as follows: Z is an integer For all m,n E Z, m D n if and only if 3 l (m^2 - n^2). Find out whether the above relation satisfies to reflexive , Symmetric & transitive? Is it an equivalence?Robert Dawson lui répond. An equivalence relation 2008-08-27 Francesca pose la question :In this problem we are told to find out if the given set is an equivalence relation or not. {(x,y) such that 4 divides x-y}. What I am confused about is whether or not for instance if I picked (1,5) as a part of the set whether I could put in (5,1) as well or whether that would be wrong. Thanks!Victoria West lui répond. Equivalence relation 2008-03-19 Hmod pose la question :State with reasons, whether the relation R on N X N given by mRn if m and n have difefrent remainders on division by 2 is an Equivalence relationVictoria West lui répond. Prove (p & ~q) v p = p 2008-02-12 Tom pose la question :Prove (p & ~q) v p = p Do I need to use the absorption law p v (p & q)=p? If yes,how do I cope with the NOT(~) in q?Thank you.Harley Weston lui répond. Equivalence relations 2007-07-18 jim pose la question :Determine whether the given relation is an equivalence relation on the set. Describe the partition arising from each equivalence relations. 1. x is Related to y in Real number if lxl=lyl. 2. n is Related to m in Z+ if n and m have the same number of digits in the usual base ten notation. Let n be a particular integer in Z+. Show that congruence modulo n is an equivalence relation on Z.Harley Weston lui répond. Two problems 2002-10-14 Eva pose la question : a) How many different equivalence relations can be defined on the set X={a,b,c,d}? b)Show that 6 divides the product of any 3 consecutive integers. I know it is true that 6 divides the product of any 3 consecutive integers. However, i have problem showing the proof. Leeanne Boehm and Penny Nom lui répond. Equivalence relations on a set of cardinality n 2002-07-06 Siddhartha pose la question :what is the no. of equivalence and transitive relations on a set of cardinality n?Penny Nom lui répond. Equivalence Relations 1999-05-06 Megan pose la question :I am tutoring a boy who got this assignment from his teacher and I have no clue how to do it because I don't even know what the questions is asking! I need some help. Hereit is: "Give five examples of relations which are not equivalent relations and five examples of equivalent relations and explain why they are equivalent relations." This is seventh grade and I read about it in his book but it is not coming together for me.Chris Fisher lui répond. Ounces and milliliters 1999-04-17 Tony Rizzi pose la question :I'm mixing a formula of: 48 oz distilled water. 15 grams of Hydroxy Ethyl Cellulose GR (powder) 30 grams of Hydroxy Ethyl Cellulose MR (powder) 200 grams of Barium Sulfate (powder) 1000 grams of Calcium Hydroxide (powder) After mixing, I need to estimate the amount of each ingredient that fits in a 3ml syringe. And how many syringes I can fill? Harley weston lui répond.
