Determine if the event described is independent or dependent.
WINSTONCH [101]
They are dependent events, because the probability of the second event depends on the result of the first event

If you replace the marble before picking up the second marble, then the first event didn't affect the second result ant the events were independent.

Given that you did not replace the marble, the second pick up has different probailities depending on the first result.

Two functions are represented below. Which function has a domain that contains the domain of the other function as a
Nikitich [7]

Answer:

\\ h(x) = x-2\;contains\;the\;domain\;of\;function\;f(x) = -log(x-2)-3

Step-by-step explanation:

The domain of a function contains all possible values that it can take.

We can analyze the function:

\\ f(x) = -log(x-2)-3 [1]

And we can see that there are three functions in [1]:

h(x) = x-2 and g(x) = -log(x) - 3, and

\\ f(x) = g(h(x)) or \\ f(x) = -log(x-2)-3.

This operation is called <em>function composition</em>.<em> </em>

For every <em>x</em>, function <em>h(x)</em> can take any value, so the domain (all possible values this function can take) is \\ -\infty\;to\;\infty (all real numbers).

However, function <em>g(x)</em> is restricted to <em>positive values</em> only, since <em>log</em> function is <em>not</em> defined for <em>negative numbers</em> and 0.

Therefore, domain for <em>f(x)</em> are <em>restricted</em> to those ones that comply with the above restriction (x > 0). So, for

\\ f(x) = -log(x-2) - 3

Possible values are those which:

\\ x - 2 > 0 or \\ x > 2

In words, the domain of <em>f(x)</em> are all values greater than 2 (but not equal to 2) or all positive real values greater than 2.

Then, the function <em>f(x)</em> has a domain that is a <em>subset</em> of function <em>h(x)</em>, that is, in function <em>h(x) = </em>x - 2, <em>x</em> can takes any possible value from -(<em>infinity</em>) to <em>infinity</em>, whereas function <em>f(x)</em> can <em>only</em> takes those values greater than two (but not equal 2) to <em>infinity</em>, which makes the domain of <em>f(x)</em>  a subset of the possible values of function <em>h(x)</em>.

Solve the formula for the perimeter of a rectangle, P = 21 + 2w for l
Phoenix [80]

2(w+l)=21+2w

w+l=10.5+w

So l = 10.5
