Answer 6

I'm not 100% sure but I believe your proportion is

2. x
---- = ----
50. 2000
And solve for x first

2/50 is the 2 defected potatoes out of the 50 sample picked out.
And using this you're trying to find x potatoes out of 2000 that would also be defected

Answer 7

@nikato so C?

Answer 8

No, did you find x?
Hint: cross multiply first

Answer 9

yeah 4000/50

Answer 10

50/4000

Answer 11

b

Answer 12

So 2(2000)=50x
4000=50x. Divide both sides by 50
x=80
And put that back into the fraction

So what's 80/2000?

Answer 13

0.04!

Answer 14

D!
