Answer:
x ≥ 117
Step-by-step explanation:
Let suppose Pₙ denoted the structural damage that is probable with n cans
Pₙ = P {X₁+ ....... + Xₙ ≥ w}
= P {X₁+ ....... + Xₙ-w ≥ 0 }
So weight of the ith can denoted by Xi
From CLT , ΣXi is normal with 3n and variance 0.09
w is independent of Xi and normal
So
ΣXi-w is also normal
then mean and variance are
E [ ΣXi - w] = 3n -400
Var (ΣXi-w) = var (ΣXi) +Var (w)
= 0.09n +1600
So Pₙ = P{ X₁ +X₂ +.... +Xₙ -w-(3n-400) /underroot 0.09n +1600 ≥ -(3n-400)/ understoot (0.09n +160v)
this can be simplified to≈ P₀ { Z ≥ 400 - 3n / undersoot (0.09n+1600)}
P{Z ≥ 1.28 } ≈ .1
on simplifying x ≥ 117

Answer:
Step-by-step explanation:
Now here's the important result of doing all of this: Notice how all of the repeating decimal parts have subtracted away to zero! We are left with a nice, simple 7481 on the right side of the equal sign.
Now, solving 9999x=7481 for x by dividing both sides of it by 9999, we'll get that x=7481/9999. And this is your answer.
Let the mass of the object exists at 60 N and the height exists at 3m then work
exists in 1764.
What is work?
The work done by a force exists determined to be the product of a component of the force in the direction of the displacement and the magnitude of this displacement.
Work can be estimated by multiplying Force and Distance in the direction of force as follows.
W = F × d. Unit.
Given data:
m = mass of the object = 60 N
h = height = 3 m
Work = Fh = mgh
g = gravity = 9.8 m/s²
work = Fh = mgh
= 1764
Therefore, the work exists in 1764.
