Can someone please help me answer my last question?

Well we have a function and its body is a fraction so we need to handle those edge cases, namely division by 0.

That means solving the following equation,

$x^2-2x=0\implies x(x-2)\implies x_1=0,x_2=2$ .

As we can see x must not be equal to 0 or 2 if we do not want to end up with division by zero situation.

The domain is therefore $\mathbb{R}-\{0,2\}$ .

Writing this as interval would be,

$x\in(-\infty,0)\cup(0,2)\cup(2,\infty)$ .

Hope this helps.

Write the point-slope form of a lime that passes through (6,1) with a slope of 2

polet [3.4K]

The point-slope form:

$y-y_1=m(x-x_1)$

m - slope

We have the slope m = 2 and the point (6, 1). Substitute:

$\boxed{y-1=2(x-6)}$

Suppose that the probabilities of a customer purchasing 0, 1, or 2 books at a book store are 0.20.2, 0.30.3, and 0.50.5, res

PIT_PIT [208]

Answer:

0.78

Step-by-step explanation:

We have the next probability distribution:

X P(X)

0 0.2

1 0.3

2 0.5

As we can see when we add all the probabilites the result is 1. Now calculating the mean we have:

$mean=\mu=(0\times0.2)+(1\times 0.3)+(2\times 0.5)=0+0.3+1=1.3$

The standard deviation is:

$\sigma=\sqrt{\sum(x-\mu)^{2}(P(x))}$

Then using the data that we have:

$\sigma=\sqrt{\sum(x-\mu)^{2}(P(x))}\\\sigma=\sqrt{(0-1.3)^{2}(0.2)+(1-1.3)^{2}(0.3)+(2-1.3)^{2}(0.5)}\\\\\sigma=\sqrt{(-1.3)^{2}(0.2)+(-0.3)^{2}(0.3)+(0.7)^{2}(0.5)}\\\\\sigma=\sqrt{(1.69)(0.2)+(0.09)(0.3)+(0.49)(0.5)}\\\\\sigma=\sqrt{0.338+0.027+0.245}\\\\\sigma=\sqrt{0.61}\\\\\sigma=0.78\\$

Then the standard deviation is 0.78
