Homework Statement Assume x is normally distributed with a mean of 5 and standard deviation of 4. Determine value of x that solves: P(-X<x-5<X) = .99 Homework Equations I have been using normalCDF and inverse functions on the TI-84 to solve, and I understand how to do these without the...

So solving for V2=V1 + 60mV[log(I2/I1)] I get D1=.64V and D2=.66v than using Kirchoff I can assume that the solution would be 1.3V? I know the whole thing is theoretical anyway because of the lack of resistance but is this the solution?

Homework Statement Given a basic circuit of a voltage source and two diodes in series: D1 is .7v @ 10mA D2 is .6v @ .1mA If I is 1mA, What is the voltage across the two diodes? Homework Equations VT~.026 Vt= 60log (I(t)/Is I1 produces V1 I2 produces V2 so V2 = V1 + 60(mV)[log...

Homework Statement A lie detector shows a positive reading 10% of the time given that the person is telling the truth and 95% given the person is lying. Suppose that there is a suspect who is denying the the crime and there is a 50% chance that the person comitted the crime. A. what is the...

Sorry.

Homework Statement For the circuit shown: Find the Thev Eq between nodes A and B and then for nodes C and D. I worked the second half of the equation but am stuck on how to begin the analysis for the opposite end of the circuit. I have attatched the image as well as posting it as I am having...

As you can see by now MATLABdude, Edward Lawry Norton is my arch nemesis. But I thank you for the help!

Homework Statement Find the Thev Eq circuit for a DC power supply that has a 30-volt terminal voltage when delivering 400mA and a 27-volt terminal voltage when delivering 600mA. Homework Equations KVL: Vs=IsR1+IsR2 Vth=Isc*Rth The Attempt at a Solution Assuming that each 3volt...

Nearing the Top MATLABdude...nearing the top. Thank you very much for the nudge back to the obvious. Sometimes it's very easy to miss the forest for the trees so-to-speak.

Homework Statement A car battery has an open-circuit terminal voltage of 12.6 volts. The voltage drops to 10.8 volts when the battery supplies 240 amps to the car's starter motor. What is the Thevenin eq for this battery? Homework Equations I think the root of my problem is the setup of...
