Square root of 9 is 3
Square root of 4 is 2
so 3/2
Make it negative and you got -3/2 for your answer.
Lets say the radius is 7 so in order to find the diameter you do 7 times 2 = 14
The diameter is 14. to find the diameter you multiply the radius but 2
Hope this helps!
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!
