What is the difference between union of sets and intersection of sets?
Space and AstronomyBoth union and intersection are the two fundamental operations through which sets can be combined and related to each other. In terms of set theory, union is the set of all the elements that are in either set, or in both, whereas intersection is the set of all distinct elements that belong to both the
Is the slope 0 or undefined?
Space and AstronomyNote that when a line has a negative slope it goes down left to right. Note that when a line is horizontal the slope is 0. Note that when the line is vertical the slope is undefined. How do you know if a slope is undefined or 0? 1.An undefined slope is characterized by a
What are the different types of statistical graphs?
Space and AstronomyThe four basic graphs used in statistics include bar, line, histogram and pie charts. What are 4 different types of graphs? The four most common are probably line graphs, bar graphs and histograms, pie charts, and Cartesian graphs. They are generally used for, and are best for, quite different things. You would use: Bar graphs
What is the range of arcsec?

Can you look at a blood moon?
Space and AstronomyIs the blood moon dangerous to look at? Not at all, unless you’re a werewolf. Unlike a solar eclipse, which is too bright to look at directly and must be viewed with special eye protection or via its reflection or shadow, the moon is merely reflecting the sun’s rays and is safe to gaze upon.
How do carnival mirrors work?
Space and AstronomyThe way that funhouse mirrors work is by being moulded into different shapes. Typically, there are two types of funhouse mirrors: Concave – The mirror is curved or bulged outwards, making your reflection appear short and fat. Convex – The mirror is curved or bulged inwards, making you reflection appear thin and tall. How do

Is the set of real numbers closed under division?
Space and AstronomyReal numbers are closed under addition and multiplication. Because of this, it follows that real numbers are also closed under subtraction and division (except division by 0). What sets are closed under division? Answer: Integers, Irrational numbers, and Whole numbers none of these sets are closed under division. Why are real numbers closed under division?
