X has to be inside the radical.
It would be
Simplify the radical by breaking the radicand up into a product of known factors.
Answer:
Now thats you've had time to think about it.
- They rotate and then move down!
- C
X=22 because if y=6 and x=10 so 6+4=10 so 18+4=22
I believe its 2 and 1/2
I'm so sorry if its not but I would guess it is :)
Number of returns = 47
Number of returns that contain errors = 5
Number of returns that does not contain error = 47 - 5 = 42
P(selecting none that contains error in the unreplaced selection) = 42/47 x 41/46 x 40/45 = 68880 / 97290 = 0.708
option C is the correct answer.
