Answer:
Step-by-step explanation:
Answer:
- Total number of cars having no defection

- Total number of cars out of 560 will have defects =

Step-by-step explanation:
As
- A car factory checks 320 cars, and
Total number of cars = 560
The number of cars defected out of the cars that have
been checked = 
The equation of the scenario will be:
⇒ 
so
- Total number of cars having no defection

- Total number of cars out of 560 will have defects =

-4x/5≥1/10
-8x≥1
x≤-1/8
x∈(-∞;-1/8]
