Answer:
Kindly check explanation
Step-by-step explanation:
Given that:
Sound quality test = every fifth siren
Mechanical quality = every 8th siren
Daily output = 350 siren
Percentage tested for mechanical quality :
Number of siren tested for mechanical quality / total output
Number of siren tested for mechanical quality = (350 / 8) = 43. 75
= 43 sirens
% tested for mechanical quality :
(43 / 350) * 100%
0.12285 × 100%
= 12.29%
What percent is tested for both types of quality at the same time?
Number tested for both types simultaneously = 8
% tested for both types of quality :
(8 / 350) * 100%
0.0228571 × 100%
= 2.28571%
= 2.29%
