The graph of a logarithmic function is shown below.

Dmitrij [34]

Domain means all the x-values include in the graph.

In this case the graph starts including x-values at 0 and all x-values that are greater then 0.

In other words x can be zero or anything larger

Technically you would show this like so:

x ≥ 0

You use the inequality symbol with the bar underneath because you want to show that 0 is included in the domain. It faces away from the zero and towards the x because x can be larger then 0 not smaller.

I guess in this case you wouldn't be including 0 so your answer is:

B. x > 0

Hope this helped!

Write an equation in point-slope form and in slope-intercept form.

Sever21 [200]

The point-slope form:

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

The slope-intercept form:

$y=mx+b$

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

We have the points (1, -5) and (-3, -7). Substitute:

$m=\dfrac{7-(-5)}{-3-1}=\dfrac{12}{-4}=-3\\\\y-(-7)=-3(x-(-3))\\\\\boxed{y+7=-3(x+3)}$

Rewrite to the slope-intercept form:

$y+7=-3(x+3)$ <em>use distributive property</em>

$y+7=-3x-9$ <em>subtract 7 from both sides</em>

$\boxed{y=-3x-16}$

In a sample of 800 U.S. adults, 199 think that most celebrities are good role models. Two Two U.S. adults are selected at rand

mel-nik [20]

Answer:

Step-by-step explanation:

Given that in a sample of 800 U.S. adults, 199 think that most celebrities are good role models. Two Two U.S. adults are selected at random from the population of all U.S. adults without replacement.

In 800 adults 199 are favourable and remaining 601 are against.

a) The probability that both adults think most celebrities are good role models is ________= Prob of selecting both from 199

= $\frac{199C2}{800C2} \\=0.0616$

=0.062

b) The probability that neither adult thinks most celebrities are good role models is _______=P(both selecting from 601)

= $\frac{601C2}{800C2} \\=0.5641$

=0.564

c) The probability that at least one of the two adults thinks most celebrities are good role models ______

=1-Prob that neither thinks

= 1- 0.564

= 0.436
