Answer:
for 4meters 0.8flaws given...so that for 8meters it will be 1.6
Total number of flas in total length of the wire = 220 * 1.6 /8 = 44
sampling taken is 8m,
Probability that one flaw to be in 212m = 212/220
for 44 flaws it will become (212/220) ^44 = 0.2
probability that the wire to be rejected = 1 - 0.2 = 0.8
probability that the roll will be rejected because one flaw as found in the sample
= (8/220) * (212/220) ^ 43
=0.008

5) A solenoid with 2 x 106 turns per meter runs through the x-y plane. It initially has a current of 7 amps running clockwise. A wire shaped like a equilateral triangle would 10 times with sides of length 2 meters is placed in the x-y plane in the solenoid. Over a a time of 0.7 seconds, the solenoid changes its current somehow which induces a (average) current in the triangle of 16 amps running counter-clockwise. If the resistance of...

Suppose that a major league baseball game has an average length of 2.9 hours with a standard deviation of 0.5 hours. It is known that game length is not normally distributed. Suppose a random sample of 36 games is taken from the population. What is the approximate probability that average game length will be greater than 3.15 hours or less than 2.75 hours? Round to the nearest thousandth.

[40 pts.] An interior designer is currently remodeling an old restaurant. Buying new chairs would cost over $1,000, while re-upholstering chairs will cost under $100. Since the budget is limited, the interior designer decided to upholster the chairs. Suppose the restaurant has 20 tables with 4 chairs each 3. Each chair requires 34 vards of fabric. The fabric used to upholster the chairs has an average of 03 flaws per vard Re-upholstered chairs can be assumed to be independent and...

A square filamentary loop of wire is 25 cm on a side and has a resistance of 125 Ohms per meter length. The loop lies in the z = 0 plane with its corners at (0,0,0), (0.25,0,0), (0.25,0.25,0), and (0,0.25,0) at t = 0. The loop is moving with velocity vy =
A square filamentary loop of wire is 25 cm on a side and has a resistance of 125 Ohms per meter length. The loop lies in the z = 0 plane with its corners at (0,0,0), (0.25,0,0), (0.25,0.25,0), and (0,0.25,0) at t = 0. The loop is moving with velocity vy = 50 m/s in the field Bz = 8 cos (1.5×108t −0.5x) µT. Derive an expression for the power as a function of time being delivered to the loop.
