mm. Determine the volume of this object.
1. Suppose the heights H of 800 students are normally distributed with mean 66
inches and standard deviation 5 inches. Find the number N of students with
heights:
a. Between 65 and 70 inches
b. Greater than or equal to 6 feet (72 inches)
2. A fair coin is tossed 12 times. Determine the probability P that the number of
heads occurring is between 4 and 7 inclusive by using the normal approximation.

Title: Designing and Simulation of a pro-type wireless transmitter system on proteus.
Task: Design, simulate and analyze an electronic communication system to transmit audio signal wirelessly using infra-red (IR) over a short distance (less than 1m). Show all design calculations, schematics, simulation results. Simulation to be done preferable via Proteus Software.
The Laplace Transform of x(t) is given below.

Determine the inverse z-transform of X(Z)=e^z, ROC:all z except |z|=infinity
. Consider the variability of the vowel characteristics among speakers. If humans can create a phoneme from similar vocal tract shapes, but with different speaker identifiability, then the source and prosody must play a large role in speaker characteristics, as well as the vocal tract. A ventriloquist, for example, can keep his/her vocal tract in roughly the same shape (i.e. for a particular phoneme), yet mimic different voices. Offer an explanation in terms of source and prosodic characteristics.
A feed mixture of A and B (45 mole % A and 55 mole % B) is to be separated into a top product containing 96 mole% A and a bottom product having 95 mole% B. the feed is 50 % vapor and reflux ratio is 1.5 times the minimum. What is the equation of the feed line? Determine the number of ideal trays required and the location of the feed tray .Given αAB = 2.8
