If F(3) then 3=x. So all you would do is substitute 3 in for x
Hello here is a solution :
1. first we find how many defective capacitors are there out of 133, 450:
in 34 capacitors --------- 1 defective
in 133,450 capacitors --------- x defective
so
![x= \frac{133,450*1}{34}= 3925](https://tex.z-dn.net/?f=x%3D%20%5Cfrac%7B133%2C450%2A1%7D%7B34%7D%3D%203925)
is the expected number of defective capacitors.
2.
So there are in total 133,450-3925=129,525 working capacitors.
3.
To assemble 1,987 smartphones the corporation needs 1,987*66= 131,142 working capacitors.
4.
The number of required capacitors is larger than the number of the available ones, so 133,450 capacitors are not enough.
