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
First we have to find the slope of the givent line and for that we use rise / run method .
The points are (-4,4),(4,-2)
Here rise is
And run is
So slope is
And the slopes of perpendicular lines are negative reciprocal of each other .
Therefore the slope of the required perpendicular line is
Now we use slope intercept form, and put x intercept , that is (6,0) and the slope that is 4/3 ,
Therefore required equation is
Correct option is the third option .
