Answer: Expected value of the daily cost of operating the machine is 235.264.
Step-by-step explanation:
Since we have given that
E[x]= 0.96 repairs per day
And Var[x] = 0.96 repairs per day.
Hence, Expected value of the daily cost of operating the machine is 235.264.
Salt flows in at a rate of (5 g/L)*(3 L/min) = 15 g/min.
Salt flows out at a rate of (x/10 g/L)*(3 L/min) = 3x/10 g/min.
So the net flow rate of salt, given by in grams, is governed by the differential equation,
which is linear. Move the term to the right side, then multiply both sides by
:
Integrate both sides, then solve for :
Since the tank starts with 5 g of salt at time , we have
The time it takes for the tank to hold 20 g of salt is such that
0.072 ÷ 345
=
≈ 0.00020
=
