Assignment:
Q1. A component has a reliability of 0.75. How many identical components do we have to add n parallel to the frst to increase the overall reliability to 0.95?
You may use the following general formulas
R_sys = 1-(1-R1)(1-R2)...(1-Ri)...(1-Rn)
Ri=e^-(lamda*t)
Q2. Find both the minimum and maximum values of U=6x1+10x2+7 (graphically) subject to the constrains 2x1+5x2<=24, x1>=0, and x2>=0
Provide complete and step by step solution for the question and show calculations and use formulas.
