Background instructions for prepping to use MATLAB during exam: Here Here declare that you have done these things and you understand how to use the MATLAB.

Iterative Methods—non-Linear ————————————–

Write a script that includes (at bottom) any functions you write (if any) and that uses Linear Regression to  fit a line onto the given data fit a cubic (degree 3) polynomial onto the given data report results as discussed below plot results as discussed below Description of data:  the x variable is displacement.  The y variable is force for a “stiffening spring” that stiffens as it displaces.  It is not exactly linear in the force vs. displacement.  Let’s find out. Things to report.  Sum of squares of residuals (from mean) Sum of squares of residuals (from line fit) Sum of squares of residuals (from cubic fit) coefficient of determination (line) coefficient of determination (cubic) Things to plot Raw data, use ‘o’ Show y average, use ‘r’ Show the linear fit line, use ‘g’ Show the cubic fit line, use ‘b’ Data  (you should cut and paste this.) x data (independent) 56789101112131415161718192021222324252627282930 y data (dependent) 812.06967.661133.91305.71467.51650.91833.22002.62208.82369.92651.72772.12942.13380.93547.43842.93976.54238.94072.35017.75143.95551.45936.35855.76310.67343.5 Upload your script to the file upload below.

Linear Regression ——————————————-

Describe what the following code snippet is doing: fs = get_fs(curr); J = get_J(curr); next = curr + inv(J)*f

Which of the following anticodons in the first tRNA to bind will complement this mRNA?

A common form of chemotherapy used to kill cancer cells is to administer drugs that disrupt cell division. Why might this also result in anemia, hair loss, and sores in the stomach and on the skin?

Refer to the figure. Which of the triplets below is a possible anticodon for a tRNA that transports proline to a ribosome?

Which of the following correctly describes the effect a nonsense mutation would have on a gene?
