Answer:

0.1

Step-by-step explanation:

chance of pulling out a blue marble can be described as 8 equally probable outcomes (blue marbles) out of 20 equally probable outcomes (all marbles).

Similarly, the chance of pulling out a green marble is 5 out of 20.

In total, we have 8*5 (combinations of blue then green) outcomes out of 20*20 (any two marbles):

8*5 / (20*20) = 40 / 400 = 1/10 = 0.1

PLEASE HELP! Which number is a rational number?
8090 [49]

Answer:

C. 17.156

Step-by-step explanation:

A rational number is any integer, fraction, terminating decimal, or repeating decimal. It can be expressed as a ratio of two integers.

The first answer wouldn't make sense, because there is no number times itself that would equal 15. Therefore, it would be irrational. Same goes with the last option.

We can also automatically rule out the second option because it is a nonterminating decimal.
