There are 10 marbles in the bag all together.
(8/10) = 80% of the marbles in the bag are white.

So if you pull a marble out of the bag, you have an 80% chance
of pulling a white one.

And if you do it many times, you expect that you'll pull
a white one out about 80% of the times.

   80% pf 45 times  =  0.8 x 45  =  36 times .

What is the domain of the step function f(x) = ⌈2x⌉ – 1?
maxonik [38]
Domain is what you can put in

the domain for most functions is ALL REAL NUMBERs
except for those that violate the dividing by zero thingummy
example
if yu had
f(x)=x+2
domain is all real numbers
f(x)=2/x
domain is all real numbers except for 0 since cannot divide by 0
f(x)=2(x-4)
domain is all real numbers except for 4


so answer is {x|x is a real number}
