Industry standards suggest that 10% of new vehicles require warranty service within the 1st year. Jackson Chevy in Detroit, MI, sold 12 cars yesterday. a. What is the probability that none of these cars requires warranty service? b. What is the probability exactly 1 of these vehicles requires warranty service? c. Determine the probability that exactly 2 of these vehicles require warranty service? d. Compute the mean and standard deviation of this probability distribution.
Assume the system shown in the Fig. is balanced, Rw = 0, Van = 208 angle 0 degree V, and positive phase sequence applies. calculate all phase and line currents, and all phase and line voltages, if Zp is equal to a) 1K ohms b) 100 + j48 ohm
A 150MW alternator generates an open-circut line-t0-line voltage of 12kV at nomial DC excitiation. When the terminals are placed in short-circuit the resulting current per phase is 8000A.
Frequency multiplers are used at the transmitter to bring up the frequency level to the transmitter level frequency. Why don't we use the crystal oscillator to generate the transmitter level frequency
Calculate the electrostatic energy that is stored in the structure if the intermediate space is filled with a dielectric whose relative dielectric constant is 10 and a voltage is applied between the conductors creating an electric field.
How tall must the antennas be if the link operates on a frequency of 2.450Ghz, D1=5miles, D2=11miles, and the obstruction is 60 feet high?
With each quadratic polynomial x^2 + ax + b with real coefficients, associate the smaller of its two real zeros. Is this association a function? If this association is not a function, explain why. If this association is a function
a resistor is required for an application that requires its value to be no less than 7.1k ohms and not more than 7.9k ohms. determine the nominal value and the maximum tolerance of the resistor you could use. explain.
An 80KHz sinusoidal voltage has zero phase angle and a maximum amplitude of 20 mV. When this voltage is applied across the terminals of a capacitor, the resulting steady state current has a maximum amplitude of 0.7 mA.
An LVDT is used in an accelerometer to measure seismic-mass displacement. The LVDT and signal-conditioning output is 0.31mV/mm with +/-2cm maximum core displacement.
calculate the average signal-to-noise (SNR) in decibels (dB) Assume equal numbers of binary 0s and 1s.
A process worker received an electric shock when she attempted to turn off a conveyer control. The toggle switch controlled the power to a variable speed drive. An examination found that dust had accumulated on the toggle switch. Moisture on the ..
A) What is the rms current in the circuit B) The primary side of the transformer has 20 times as many turns as the secondary side. What is the rms voltage across the primary side of the transformers
