Answer:
Step-by-step explanation:
The answer will be C. OR 3. 11−<span>13<span>i</span></span>
8 were defective.
Defective percent = 8/84 x 100 = 9.5238% were defective.
Percent not defective = 100% - 9.5238% = 90.4761%
Rounding to the nearest tenth 90.5% were not defective.
The question doesn’t say how to round the answer so you may need to round differently than I did.
I think the answer would be x= 4/7 y = +-16/7
