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
The right answer for the question that is being asked and shown above is that: "d. The value of a number substituted for x is greater than 6.; b. The solution set is {6, 7, 8, …} for x ∈ N."<span> These are the statements and number lines that can represent the inequality. </span>
Answer:
x > 3/2
Step-by-step explanation:
Simply the expression and get 6x - 4 > 8 - 2x
Move terms and simplyfy: 6x + 2x > 8 + 4
Divide both sides: 8x > 12
x > 3/2
Since you didn’t put the numbers to find the amount, I’ll teach you how to.. Once you have the decimal figure, multiply it by the number for which you seek to calculate the percentage
C.
4 (x+7) = 38 represents the tape diagram correctly.
