Which of the following are not two of the best ways to staysafe around electricity? a. maintain a safe distance from overhead power lines, and follow proper lockout/tagout procedures. b. use electrical safety devices and check extension cords once a year for any abrasions or cuts c. use ground-fault circuit interrupters, and inspect extensions cords and portable tools.

7. design a circuit with three inputs (x, y, and z) representing the bits in a binary number, and three outputs (a, b, and c) also representing bits in a binary number. when the input is 1, 2, or 3, the binary output should be one lesser than the input. when the input is 4, 5, or 6, the binary output should be one greater than the input. when the input is 0, the output is 0, and when the input is 7, the output is 7. show your truth table, all computations for simplification, and the final circuit.
