A varies directly with b → a = kb where k is the constant of variation (i.e. slope)
-2 = k × 3 ← substitute values into the formula above
-2/3 = k ← result of dividing both sides by 3
Answer: k =

Answer:
0.812 = 81.2% probability that a randomly chosen chip will pass the test
Step-by-step explanation:
Over the long run, the fraction of bad chips produced by the process is 20%.
So 100 - 20 = 80% are good.
All good chips pass the test, while 6% of the bad chips(20%) also pass.
a) (4 points) What is the probability that a randomly chosen chip will pass the test
0.812 = 81.2% probability that a randomly chosen chip will pass the test
