Explain the differences between fixed and random factors in Design of Experiments (DoE).Explain the three pillars of DoE

During the semester, we talked a lot of impact of People, Process and Technology. All of the above come together to either help Enterprises thrive in business or vanish. One important point of intersection is the relationship between the Enterprise Structure and Culture. There is a general assumption that the Enterprise structure and Enterprise culture impact each other. In a domain of your choice, with examples, First, outline the mechanism through which Enterprise Culture impacts the design of Enterprise Structure, how the culture affects the long term maintenance, strengthening, or changing of enterprise structure. Second, based on the known classifications of Enterprise structure, please provide examples of kind of culture that would exist and mutual interdependence with structure. Pros and Cons of both scenarios.

4. Consider the following three IC curves:

PG1 = -100+50(IC) 1 – 2 (IC)12

PG2 = -150+60(IC) 2 – 2.5 (IC)22

PG3 = -80+40(IC) 3 – 1.8 (IC)32

Where ICs are in Rs/MWh and PGS are in MW. The total load at a certain hour of the day is 400 MW. Neglect transmission loss and develop a computer programme for optimum generation scheduling within and accuracy of + 0.05 MW

A major League pitcher stands on top of a 100m cliff. He throws a baseball straight upwards with a speed of 30.5 m/s. ignore air friction, ignore the height of the pitcher.

Q: What is the maximum height above the ground the ball rises to?
Q: What is the path length of the ball for the entire trip from hand?
Q: What is the average velocity of the ball for the entire trip from hand to the ground below just before hitting the ground?

pls show me how to work this out.
