Answer:
The inverse is ±sqrt((x+4)/9)
Step-by-step explanation:
y = 9x^2 – 4
We want to find the inverse
Exchange x and y
x = 9y^2 -4
Solve for y
Add 4 to each side
x+4 = 9y^2 -4+4
x+4 = 9y^2
Divide each side by 9
(x+4)/9 = 9/9y^2
(x+4)/9 = y^2
Take the square root of each side
±sqrt((x+4)/9) = sqrt(y^2)
±sqrt((x+4)/9) = y
The inverse is ±sqrt((x+4)/9)

The best information we can use is the ratio of defectuosity, 2/150
Applying it to the size of the batch
N=3000*2/150 = 40
Answer: out of the batch of 3000 products, likely 40 products are defective, if the products are drawn from the same production run.
A. 4
to complete the square, take half of the the second number and square it
