Answer:

Option A is correct.

-\frac{2}{3}x +\frac{2}{5}

Step-by-step explanation:

Given that: -2(\frac{1}{3}x-\frac{1}{5})        .....[1]

The distributive property says that:

a\cdot (b+c) = a\cdot b + a\cdot c

Apply the distributive property in equation [1] we get;

-2 \cdot \frac{1}{3}x + 2 \cdot \frac{1}{5}

Simplify:

-\frac{2}{3}x +\frac{2}{5}

Therefore, the expression that shows the result of applying the distributive property to  -2(\frac{1}{3}x-\frac{1}{5}) is, -\frac{2}{3}x +\frac{2}{5}

lbvjy [14]

Answer:

So, the probability is P=0.0097.

Step-by-step explanation:

We know that the  number of flaws in a certain type of lumber follows a Poisson distribution with a rate of 0.45 per linear meter.  

We conclude that  λ=0.45.

We use the Poisson formula:

\boxed{P(X=k)=\frac{\lambda^k\cdot e^{-\lambda}}{k!}}

We calculate the  probability that a board 3 meters in length has no flaws. We get that k=3.

We calculate:

P(X=3)=\frac{0.45^3\cdot e^{-0.45}}{3!}\\\\P(X=3)=0.0097\\

So, the probability is P=0.0097.
