Refer to Exercise 5.69. The company purchasing the machines returns the defective ones for repair. If it costs $50 to repair each machine, find the mean and variance of the total repair cost. In what interval would you expect the repair costs on these five machines to lie? [Hint: Use Tchebysheff's Theorem.]
Exercise 5.69
A warehouse contains 10 printing machines, 4 of which are defective. A company randomly selects five of the machines for purchase. What is the probability that all five of the machines are non-defective?
Charge is distributed uniformally along a straight wire. the electric field 2 cm from the wire is 20N/C. The electric field 4cm from the wire is:
Create an array, array1, that has the last 14 elements of which the first element is 49 and the last element is 10. THen using the colon symbol create a new array, array 2, whcih has 8 elements. the first 4 elements of array 2 are the 4th through ..
Design a logic circuit that receives an 8-bit binary number as input and determines the location of the most-significant "1" in that binary number. The output of your circuit is the location given using one-hot encoding.

A student attempts to measure his own ECG on an oscilloscope having a differential input. For Figure 6.11, Zin ¼ 1MV, Z1 ¼ 20 kV, Z2 ¼ 10 kV, ZG ¼ 30 kV, and idb ¼ 0:5mA. Calculate the power-line interference the student observes.
Delta load Assume that the load is delta connected. Each phase has a series RL load with R = 5 ohms and L = 20 mH. Plot the phase to phase voltage (Vab) versus time for one cycle. Hint: Vab = Va - Vb
Heat is added until the final volume is twice the initial volume. Assume that Helium behaves as an ideal gas. Use the table provided to determine the specific heats of helium and determine the following. Find the temperature at the final state.
Design a 2's complementer with a shift register and a flip-flop. The binary # is shifted out from one side and it's 2's complement shifted into the other side of the shift register.
Examining frequency to time domain signals, A spectrum analyzer is connected to an unknown signal. The spectrum analyzer displays the power level of signals in dBm vertically and frequency horizontally. The spectrum of the unknown signal creates t..
Find the transfer function and the difference equation for a 2nd -order FIR filter that has unity d.c. gain, but for which the given input x(k) produces zero forced response. (Your filter will have a "notch" at the given frequency, and H(1) =1.)
Using your knowledge of ‘State Machine' design from logic design principles, draw the state diagram for the 2-bit down-counter, generate the state transition table, the flip-flip input equations for D Flip Flop, and finally the logic diagram of th..
