# which of the following is an empty set

We should do our best to avoid this in the name of human solidarity, but the fact is that , for now, this is not an empty set. We call a set with no elements the null or empty set. (A) x | x is a real number and x2 - 1 = 0 (B) x | x is a real number and x2 + 3 = 0 (C) x One positive integer is 7 less than twice another. The supremum of the empty set is $… modapallivandana modapallivandana 2 weeks ago Math c) In the scope of Euclidean geometry, no line drawn on the surface of a sphere is a straight line. Get your answers by asking now. Inform you about time table of exam. You can draw straight lines on the surface of a sphere. 12.3 depicts an archery target marked with its fivescoring regions from the centre ​. (b) Use the properties in Theorem 5.2.2 to prove the A set of planets with more than one satellite. The diameter of the region representingGold score is 21 cm and each of the other bands is 10.5 cmwide. the set of whole numbers less than one billion. b) No month of the year has 32 days, so we have the empty set. This makes sense since the infimum is the greatest lower bound and every real number is a lower bound. c) In the scope of Euclidean geometry, no line drawn on the surface of a sphere is a straight line. (A) x | x is a real number and x2 - 1 = 0 (B) x | x is a real number and x2 + 3 = 0 (C) x 1. How many Months have 32 days. So, 2 is an even prime number. Still have questions?

COMEDK 2014: Which of the following is an empty set? In some contexts a great circle can be considered a straight line. For example: Set Q is inhabited, and contains the following three elements: x, y, z Q = {x, y, z} Set Ø (Null Set) is empty.

A directory of Objective Type Questions covering … Ask your question. b - I did set theory with the OU and am 98% sure. ∴ D = { } Hence it is an empty set. It is represented by the symbol { } or Ø. If the area of a rectangular yard is 140 square feet and its length is 20 feet.

I think we can safely assume that straight means straight in the Euclidean sense, and that "on the sphere" means that the entire line lies completely on the sphere. You can sign in to vote the answer. Find its width.? The set of months of the year with 32 days, c. The set of straight lines drawn on the surface of a sphere, d. The set of prime numbers between 35 and 43, The answer is 'b'. It contains no elements: "nothing". Set b is the answer. The set that does not contain any element is called empty setOption B defines the set of real numbers for x2 + 1 = 0 x2 = - 1 x = √(-1) = i which is an imaginary number but our set is defined on real numbersSo option B is correct In a section on set theory, I doubt they're trying to throw you a curve ball on non-Euclidean geometry. COMEDK 2014: Which of the following is an empty set? So, we have the empty set ( I suppose you mean the entire line lies on the sphere's surface). I guessed b and c but not sure... b. How do you use the quadratic formula, step-by-step. b. So, we have the empty set ( I suppose you mean the entire line lies on the sphere's surface) d) Clearly this is not the empty set, because 37 and 41 are prime and lie between 35 and 43.
