That would be 400 / 28 = 14.29 gallons to nearest hundredth
Answer:

Step-by-step explanation:
Given number is
. We need to find the complex conjugate of the given number.
We will use the general rule to find out the complex conjugate of the number.
The complex conjugate of
will be 
And the complex conjugate of 
So, the complex conjugate of
is 
Answer:
0.03333
Step-by-step explanation:
Given that there are three machines. All of the machines can produce 1000 pins at a time.
Chance for any machine is thus equaly likely = 1/3
The rate of producing a faulty pin from Machine 1 be 10%, from Machine 2 be 20% andfrom Machine3 be 5%.
Machine I II III total
Faulty 0.10 0.20 0.05
Prob 0.3333 0.3333 0.3334 1
Faulty*prob 0.03333 0.06666 0.16665 0.26664
Thus probability that a produced pin will be faulty and it will be from the firstmachine
= 0.03333
