you check 20 batteries 14 of the batteries do not have charge What is the experimental probability that the next battery you check does not have charge? Out of the next 70 batteries that you check how many would you expect to not have a charge?

49/70

Step-by-step explanation:

14 x 3.5    49

20  x 3.5   70

6^2 or 36

step-by-step explanation:

6000n

6×1000n

6×10^3 n

so we need 6n need to be a perfect cube

so n has to be 6^2 so that 6n is 6^3

what i'm saying is if you let n be 6^2 you have 6^3×10^3 or 60^3 which is a perfect cube
