Algebra.Com's Answer #219973 by jim_thompson5910(35256)![]() ![]() ![]() You can put this solution on YOUR website! p ∈ A simply states \"the element 'p' is in the set A\". Since this is NOT true (p is nowhere to be found in A), p ∈ A is NOT true.\r \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Similarly, 5 is also NOT in A. So 5 ∈ A is also NOT true.\r \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Since r is in A, this means that r ∈ A is true and r ∉ A is false.\r \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Also, 's' is in A. So s ∈ A is true.\r \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Finally, since A is NOT the empty set, A is NOT a subset of the empty set. Remember, the only subset of the empty set is the empty set itself. So A ⊆ Ø is false. \n" ); document.write( " |
