You and your friend go into sports bar where a dart throwing competition is going on.you buy m darts at 1 dollar each.you throw these m darts at the board.Of these, N darts hit within the inner circle. Your friend picks up these N darts, and throws them at the board . X of them hit the inner circle.you and your friend earn 10 dollars for each of the X hits, Of course N and X are random numbers. Assume that your throws are independent and each has a probability p1 of hitting the inner circle.Your friend's throws are also independent,and each has a probability p2 of hitting the inner circle.
a)Let m=100,p1=0.5,p2=0.1. Use Monte Carlo Simulation to find out: Should you join this game? How much do you expect to win from this game? Does it matter who goes first?
b)what is the distribution of X?(ie.,write the p.m.f of X,or equivalently, name the distribution and give its parameters)?
A 2000-ft vertical curve connects a +3% grade to a -5% grade. If the vertical tangents intersect at sta. 52 + 60.55 and elevation 877.62 ft, calculate the elevations at the VPC, VPT, high point, and sta. 54 + 00.
A single-stage rocket is launched vertically from rest, and its thrust is programmed to give the rocket a constant upward acceleration of 6 m/s^2 . If the fuel is exhausted 20 s after launch, calculate the maximum velocity and the subsequent maxim..
Determine the maximum rimpull of the tractor in each of the indicated gears if the efficiency is 92%. If the tractor is operated over a haul road whose slope is +2.5% with rolling resistance of 80 lb/ton
Determine, for the crest and sag vertical curves required, the stationing and elevation of the PVCs and PVTs given that the PVC of the crest curve(on westernmost level highway section) is at station 0+00 and elevation 100 ft.
Estimate the inside diameter, wall thicknes and outside diameter of the pipe. The carbon steel pipe has tensile yield strength of 250 MPa. Assume safety factore of 2 and a corrosion allowance of 2mm. The maximumoperating pressure (MOP) is 55 bar.
Truck B has an 8000-lb single axle and a 43,000-lb tandem axle. On a flexible pavement with a 3-inch hot-mix asphalt (HMA) wearing surface, a 6-inch soil-cement base, and an 8-inch crushed stone subbase, which truck will cause more pavement damage
A dispersed plug chemical reactor has an influent flow with concentration of 150 mg/L of A and a flow rate of 100 gal/min (380 L/min). The reaction is first order, The rate equation : - dC/dt = kC= -r , and the rate constant is 0.4 h^-1 .
How high (m) a column of ethyl alcohol would be required to give the same pressure as 700 mm Hg
A rigid open cylinder having an inside diameter of 15 mm contains a column of water 500 mm long at 20 degrees C. If a compressive force of 2 kN is applied to the top of the water column by a frictionless 15 mm piston
A disabled automobile is pulled by means of two ropes as shown. The tension in AB is 400 lb and the angle is 20. knowing that the resultant of the resultant of the two forces applied at A is directed along the axis of the automobile, determine by ..
A field sample of medium sand with median grain size of 0.84 mm will be tested to determine the hydraulic conductivity using a constant-head permeameter. The sample has the length of 30 cm and a diameter of 5 cm.
A total of 13,610 kg/h of air at 1 atm abs pressure and 15.6C is to be heated by passing over a bank of tubes in which steam at 100C is condensing. The tubes are 12.7mm OD, 0.61 m long, and arranged in-line in a square pattern with Sp=Sn= 19.05mm.
