Algebra.Com's Answer #399616 by jim_thompson5910(35256)![]() ![]() ![]() You can put this solution on YOUR website! L = {x l x is an integer between 20 and 40, inclusive}\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "L = {20, 21, 22, 23, ... , 35, 36, 37, 38, 39, 40}\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "So we're trying to count all the integers from 20 to 40 (including both 20 and 40). So we can use the handy shortcut\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Number of numbers from X to Y = Y - X + 1\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Number of numbers from 20 to 40 = 40 - 20 + 1\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Number of numbers from 20 to 40 = 21\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "So the cardinality of set L is 21 \n" ); document.write( " |
