Answer:
0.8 cm
Step-by-step explanation:
I divided 0.6 by 3 and then multiplied by 4 because 0.6 is 3/4 of the portion and we need the other 1/4.
When the base is the same, and it is a ÷, subtract the exponents (if it is a ×, add the exponents):
-11/3-(-2/3)=-9/3=-3
4^(-3)=1/4³=1/64
the first choice is correct.
Answer:
2/15
Step-by-step explanation:
There is a 4/10 probability that she chooses blue the first time, but the second time it is a 3/9 chance because she didn't put the marble back so there are 9 marbles in total, 3 blue ones.
4/10 x 3/9 = 2/5 x 1/3 = 2/15
I hope this helps :)
Edit: Messed up the multiplication, whoops!
