Answer:A device tests whether each blinker on a car is functioning properly. A company estimates that 2.8% of blinkers that they produce are defective. The device is 98% accurate for blinkers that are functioning properly and 96% accurate for blinkers that are defective. You use the device to test a randomly selected blinker. What is the probability that the test result is correct?
Step-by-step explanation:SRRY had to meme a little bit it's 40%
x = 6
given x varies inversely with y then
xy = k ← k is the constant of variation
to find k use the condition x = 4 when y = 9, hence
k = 4 × 9 = 36
x = 
← inverse variation equation
when y = 6, then x = 
= 6
