The number of milligrams of a certian subtance per liter in samples of drinking water all tested within .05 to 40 milligrams per liter. Write this information as an inequality, using absolute value.
\n" ); document.write( "-------------
\n" ); document.write( "1st: Find the mid-point between 0.05 and 40: (40+0.05)/2 = 20.025
\n" ); document.write( "2nd: Find the distance from the midpoint to an end point:
\n" ); document.write( "40-20.025 = 19.975
\n" ); document.write( "3rd: Set up the absolute inequality:
\n" ); document.write( "|x-20.025|< 19.975\r
\n" ); document.write( "\n" ); document.write( "================
