Waterfall model is a. linear-sequential model b. linear-combinational model c. non-linear-combinational model d. constant-sequential model

Inference question in discrete mathematics. Use the example solution in the picture to solve this inference question. Given the premises: If the steak is well done, it’s overcooked. If the steak is overcooked, the fire alarm will go off. Either the batteries have been changed or the fire alarm will not go off. The batteries have only been changed if the ladder is in the room. The ladder is not in the room. Conclude that the steak is not well done. These premises don’t make sense in the real world. Why? How can you change the premises so that they make sense in the real world? (They don’t have to end up perfectly correct, but they need to avoid the obvious problems you uncover in part B.)

You are developing a simulation model of a service system and are trying to create an input model of the customer arrival Process, You have the following four observations of the process of interest [86, 24,9, 50] and you are considering either an exponential distribution Of a uniform distribution for the model. Using the data to estimate any necessary distribution Parameters, write the steps to plot Q-Q plots for both cases i.e. exponential and uniform.

I need some help in how to use the MATLAB Histogram function in order to take two different random variables, and show the Central Limit Theorem as they converge to normal (gaussian) distribution. Understanding Matlab and its commands is tricky for me. So thankyou again!

Write the code in matlab.

1) Consider the system below. The plant is given by: and where 9 and The system uses state feedback control. Choose the desired closed-loop poles to be at and. Using MATLAB: a) Plot the step responses without state feedback. b) Determine the stability of the system with an eigen value approach. c) Determine the stability of the system with an Routh Hurwitz approach. d) Determine the state feedback gain matrix with a Pole Placement approach. e) Determine the new system and plot its step response.
