Answer:
The maximum value of z is 244 at x= 8 and y=49.
Step-by-step explanation:
We are given the system of equations as,
Maximize :
Subject to :
After plotting the inequalities to which the maximized function is subjected to, we get the following graph.
So, we will find the value of 'z' at the enclosing the solution region.
(2,4) z= 6×2+4×4= 12+16 = 28
(2.273,3.182) z= 6×2.273+4×3.182 = 13.64+12.73= 26.37
(8,49) z= 6×8+4×49 = 48+196= 244
Thus, we get that the maximum value of z is 244 at x= 8 and y=49.
Answer:
2.9106
Step-by-step explanation:
According to the information of the problem
Year 75 76 77 78 79 80 81 82 83 84 85 86 87
Lean 642 644 656 667 673 688 696 698 713 717 725 742 757
If you use a linear regressor calculator you find that approximately
so you just find and then the predicted value would be 106mm
therefore the predicted value for the lean in 1918 was 2.9106
