Algebra.Com's Answer #802119 by Theo(13342)![]() ![]() You can put this solution on YOUR website! the formula to use is:\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "y = .87 * x + 4.06\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "when x = 7, y = .87 * 7 + 4.06 = 10.15\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "when x = 9, y = .87 * 9 + 4.06 = 12.064.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "this translates to:\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "when the number of automatic weapons is equal to 7,000, then the number of murders per 100,000 is equal to 10.15.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "when the number of automatic weapons is equal to 9,000, then the number of murders per 100,000 is equal to 12.0564.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "the correlation is positive.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "the higher the number of automatic weapons, in thousands, the greater the murder rate per 100,000 residents.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
