A firm manufactures three different types of hand calculators and classifies them as small, medium, and large according to their calculating capabilities. The three types hone production requirements given by the following table
Small medium large
Electronic circuit component 5 7 10
Assembly time (n) 1 3 4
Cases 1 1 1
The firm has methyl limit of 90.000 circuit components, 30.000 hours of labor and 9000 cases. If the profit is birr 6 for the small, birr 13 for the medium and birr 20 for the large calculator, then
A. How many of each should be produced to yield maximum profit
B. What is the maximum profit?

the probabilities a team wins draws or loses any particular game at 0.6, 0.1, 0.3 respectively. find the probability that the teams wins at least one of its next two games
. A new machine is being considered to replace the
old machine being used. This new machine was
tested for 10 consecutive hours with the following
output: 119, 122, 118, 122, 120, 124, 126, 125, 125,
and 124. If the average output per hour using the old
machine is 120 units, is the management justified in
stating that the output per hour can be increased with
the new machine? Use a 0.01 level of significance.
Maximize z = 15x1+45x2
Subject to x2<= 50, x1+1.6x2<= 240, 0.5x1+2x2<=162 and all x1,x2=>0.
If Maximize z° = c1x1+c2x2 and c2 is fixed at 45, determine how much c1 can be changed without affecting the above optimal solution.
