A bag contains 6 brown, 8 white, and 4 black marbles. Each time you take a marble out, you do not put it back into the bag. Find the Probability of pulling a black marble
and then another black marble. (In simplest form--always!)
P(black, black)

4.44

Step-by-step explanation:

Total NM of ball=18,

black ball=4

p(black,black)=?

p(black,black)=p(b)+p(b)

4/18+4/18=4.44ans

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11 -1> 1 -1+ a

-12 > a

answer: solve 5\cdot 2^x=2405⋅2  

x

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}  

5⋅2
