Purchasing a Pizza The probability that a customer selects a pizza with mushrooms or pepperoni is 0.43, and the probability that the customer selects only mushrooms is 0.32. If the probability that he or she selects only pepperoni is 0.17, find the probability of the customer selecting both items.
1. Building a New Home In building new homes, a contractor finds that the probability of a home buyer selecting a two-car garage is 0.70 and of selecting a one-car garage is 0.20. Find the probability that the buyer will select no garage. The builder does not build houses with three-car or more garages.
2. In Exercise 28, find the probability that the buyer will not want a two-car garage.
3. Suppose that P(A) = 0.42, P(B) = 0.38, and
P(A U B) = 0.70. Are A and B mutually exclusive? Explain.
how can i write code to vhdl i have lab 7-segment led display decoder that takes 4- bits binary input and display
Assume that at this point when Av*β = 1, phase shift due to the amplifier is 120 degrees. A 0.001 micro farad capacitor is added in parallel with Rf in the feedback circuit. What is the new phase shift at the frequency where Av*β = 1
The amplifier is connected to the handset antenna which has an impedance of 35 + j10 at one unspecified operating frequency. Find the inductive reactance and capacitive reactance needed to match the transmitter output to the antenna
I've spent two days trying to come up with a circuit that can connect all of these sensors to the arduino and then send data through a gsm shield to a mobile phone (SMS) when [the room temperature, body temperature, heart rate, fall or rise above/be..
An electron is traveling horizontally along the positive x-axis at a speed 3.00 x 106 m/s. After it passes the origin, it enters a constant E field with a strength of 200 N/C and directed 45 degrees up from the x-axis.
The transmitting fiber has a core diameter of 80µm and the receiving fiber has a core diameter of 110µm. The transmitting fiber has n1=1.46 n2=1.40 and the receiving fiber has n1=1.48 and n2=1.46. Will this joint meet the loss restrictions
Solve these equations to find the expressions for the phasors corresponding to the voltages across the resistor and the capacitor.
Consider a 3 phase, 2 pole induction machine. Neglect the stator windings resistance and the leakage inductance. The rated voltage is 208 V (line-line, rms) at 60 Hz. Lm=60 mH, and the peak flux density in the air gap is 0.85T.
The ac source has an rms value of 20 V and a frequency of 60 Hz. The diodes are ideal, and the capacitance is very large, so the ripple voltage Vr is very small. The load is a 100-Ω resistance. Determine the peak inverse voltage across the diode a..
A GaAs device is doped with a donor concentration of 3e^15/cm^3 . For the device to operate properly, the intrinsic carrier concentration must remain less than 5% of the total electron concentration
Give three advantages of a three-phase system over a single-phase system There are two basic three-phase connections, the wye connection and the delta connection. Draw a labelled diagram showing the wye connection
