W = 0.001x^3+0.03x^2+1.2\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "W = 0.001(14)^3+0.03(14)^2+1.2 ... plug in x = 14\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "W = 0.001(2744)+0.03(196)+1.2\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "W = 2.744+5.88+1.2\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "W = 9.824\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The estimated weight is 9.824 ounces
