HELP NEEDED:600 rounds are fired from a gun at a horizontal target 50m long which extends from 950m to 1000m in range from gun.The trajectories of the rounds all lie in the vertical plane through the gun and the target.It is found that 27 rounds fall short of the target and 69 rounds fall beyond it.Assuming that the range of rounds is normally distributed,find the mean and standard deviation of the range.Estimate the number of rounds falling within 5m of the centre ot the target.

Thanks!

i)at st pt,dy/dx(f"(x)=0
2x-6=0
x=3
ii)intergrate f"(x)=x^2-6x+c
when x=3,y=4
-4=(3)^2-6(3)+c
c=5
f(x)=x^2-6x+5
