Of 200 grapes that were tested, 60 were decaying. In a random sample of 50 grapes, how many do you expect to be decaying?
\n" ); document.write( "-----------
\n" ); document.write( "Use a proportion:
\n" ); document.write( "decay/total = decay/total
\n" ); document.write( "---
\n" ); document.write( "x/50 = 60/200
\n" ); document.write( "---
\n" ); document.write( "x = (50*60)/200
\n" ); document.write( "---
\n" ); document.write( "x = 3000/200
\n" ); document.write( "---
\n" ); document.write( "x = 15
