A midcareer engineer hopes to have $2 million available for his use when he retires 20 years from now. He plans to deposit a uniform amount semiannually, beginning now and every 6 months thereafter through the end of year 20. If his investment account has a yearly return of 8% per year, compounded quarterly, the interest rate, i, that must be used in the A?F equation to determine the size of the uniform deposits is:
(a) 2%
(b) 8.24%
(c) 8.00%
(d) 4.04%
i/6-mths = (1 + 0.04/2)² – 1 = 0.0404 (4.04%)
Answer is (d) 4.04%

What is the difference between the sign-magnitude and 2's-complement systems of representing signed binary numbers?
A) In the 2's-complement system, all positive numbers are entered in the 2's-complement form preceded by "0" to indicate the sign and all negative numbers are entered in straight binary format preceded by a "1" to indicate the sign. The sign-magnitude system requires that positive and negative numbers be entered in straight binary form preceded by a "0" or "1" to indicate the proper sign. B) In the 2's complement system all numbers, regardless of signs, are entered in the 2's-complement preceded by a "1" or "0" to denote sign. In the sign-magnitude method, the magnitude bits represent the true binary value and the bit preceding the MSB represents the sign of the following bits. C) In the signed-magnitude system all numbers, regardless of their sign, are in straight binary format preceded by a "0" or "1" to denote the sign. In the 2's complement system, the negative numbers are entered in the 2's-complement form preceded by a "1" to acknowledge a negative number whereas positive numbers are entered in straight binary format preceded by a "0" to indicate the sign. D) In the sign-magnitude system all numbers, regardless of their sign, are in the 2's-complement form preceded by a "0" or "1" to indicate their sign. On the other hand, the 2's-complement system requires the sign-magnitude bits be in straight binary format preceded by a "0" or "1" to denote the proper sign.
