The grades of a group of 1000 students in an exam are normally distributed with a mean of 70 and a standard deviation of 10. A student from this group is selected randomly.
a) Find the probability that his/her grade is greater than 80.
b) Find the probability that his/her grade is less than 50.
c) Find the probability that his/her grade is between 50 and 80.
d) Approximately, how many students have grades greater than 80?
a three- wire system has a balanced Y- connected load with a75-Ω resistance, 125- mH inductance, and 55-μFcapacitance in series from each line to the neutral point. assuming positive phase sequence with Vp= 125V at 60 Hz
Balanced 3-φ system with the line voltage of 866 V, the frequency of 60 Hz, and with Y - connected source feeds ?-connected load with the impendence of 174 - j249 Ω. Line impedance is 2 + j3 Ω and phase sequence is positive.

Find the permittivity of a parallel-plate capacitor if its capacitance is 100 ?F, the dimension of each rectangular plate is 1cm by 0.5cm, and the distance between the plates is 1mm.
How to determine the proper Cable Size for Given Load (with Examples) ?
Determine the corona lossof a three phase, 220kV, 50 Hz and 200km long transmission line of three conductors each of radius 1 cm and spaced 5m apart inequilateral triangle formation. The air temperature is300C and the atmospheric pressure is 760mm..
The samples are binary PCM encoded into n bits whichare transmitted using two waveforms S1 (t)=1.414 sin(w1t) and S2(t)=1.414 sin(w1t) + 1.414 cos(w1t) where t is between 0 and Tb,and the a priory probability of S1 is p(s1) = 0.4.
