Answer:
The year 2021.
Step-by-step explanation:
75% here means a the answer to our function is 75.
Thus, f(t) = 75
Now let's solve the equation for the variable t:
Solving for t using the quadratic formula we get:
t1 = 21.477
t2 = -6.124
As t is the number of years after 2000, and t can not be less than 0, our answer is t1.
This mean the percent is predicted to reach in the middle of the year 2021.
converting the number 0.477 to months we get: 0.477*12 = 5.72
This means the middle of may.
So our answer is May, 2021. And the year is just 2021.
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
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.
