Answer:
F is reduced by 31%
Step-by-step explanation:
F = 1/(d²)
now, we increase the distance by 20% (multiply by 1.2).
F new = 1/(1.2×d)² = 1/(1.44×d²) = (1/1.44) × (1/(d²)) =
= 1/1.44 × old F = 0.69 × old F
100 - 69 = 31%
Lets look at the info we have:-
400 personal video players and find that 399 have NO defects.
Solve:-
2000 ÷ 400 = 5
So, about 5 of the video players will be defect.
