Create a function that adds grades to a student record. for the parameters, it will accept one student dictionary, a string representing an assignment name, and a grade. if the assignment name does not exist in the student’s list of assignments, then the assignment and grade will be added to the end of the list of assignments. if this operation was successful then the function will return true otherwise it will return false.

Using least squares fitting, you are to fit the data sets to the following models and solve for the parameters ai , where i is the index of the parameter. the input/output data for the systems are linked in the bblearn site. for each of the systems use matlab to plot the supplied data vs. the model fit on one plot. include your code in the solutions. (a) linear fit "lineardata.mat" y=a1x^3 + a2x^2 + a3x + a4 (b) plant fit "plantdata.mat g(s) = a1/(s + a2)

Write the pseudo code for this problem based on what you learned from the video. the purpose is to design a modular program that asks the user to enter a distance in kilometers, and then converts that distance to miles. the conversion formula is as follows: miles = kilometers x 0.6214
