So the numbers you are thinking of are the integers between 7 and 12. \n" ); document.write( "ANSWER: Your numbers are 8, 9, 10, and 11. \n" ); document.write( "NOTE: \"between 40 and 65\" in the statement of the problem is ambiguous; we don't know whether or not 40 and 65 are included. My interpretation is that they are not.... \n" ); document.write( " \n" ); document.write( " |
