A company produces optical-fiber cable with a mean of 0.6 flaws per 100 feet. What is the probability that there will be exactly

Mars2501 [29]

Answer:

$P(X = 4) =0.133$

Step-by-step explanation:

From the question we are told that:

Mean $\x=0.6/100$

Flaws $f=4$

Distance $d_2=1000ft$

Generally the equation for Poisson mean lambda over 1000 is mathematically given by

$\lambda=0.6*1000/100$

$\lambda = 6$

Therefore

$P(X = 4) = {e^-\lambda * \lambda^{\=x}} {{\=x}!}$

$P(X = 4) =\frac{ e^{-6} * 6^4}{ 4!}$

$P(X = 4) =0.133$

4 to the 3rd power X blank =1 what is the blank?

BaLLatris [955]

If you mean this: $4^{3x} = 1$ then x = 0. The property in play here is the following: Any number raised to the "0" power is equal to "1". In this case, we would need to set the exponent of 3x = 0 and solve for x...

If you mean the equation: $4^{3} x = 1$ then to solve for x(your blank), simply divide both sides of the equation by $4^{3}$ :

You would have x = $\frac{1}{4^3}$ this can also be written as $4^{-3}$
