Textbook Question
Chapter 15.5, Problem 18CC
- a. Create a variable named MTS containing the text My here’shat
- b. Create a variable named D containing 17 blanks followed by your name followed by 691 more blanks.
- c. Assume Avian=’A wet birt never flick at right’;
Modify Avian so that the word “wet” is replaced with the word “crepuscular” and the word “never” is replaced by “seldom”. Note that you should actually modify ONLY the two words in question, not simply type in the complete new sentence.
- d. Assume Ultimate=’The answer is 42’;
Convert the substring “42” in Ultimate into its corresponding numeric value and place it in UltAns. Your solution should work as long as the “number” at the end of the string is exactly two digits. HINT: Look in Table 15-8.

Could you please fix my code it’s supposed to look like the graph that’s on the picture. But the lines do not cross eachother at the beginning. Could you make the lines look like the lines on the graph?
Use this code in MATLAB and fix it.

There is a small space between the orange and purple line could you please connect the two lines together also can you please make the purple line shorter and then connect the purple line to the orange line, please take out the box that says “Diesel, petrol, Diesel best fit, petrol best fit”. Also when ever I run this code the graph shows up but there are still errors that comes up could you please fix them when you are running this on MATLAB.
Please use this code on MATLAB and fix it.

I need help with the purple line the line that you see one the graph on the picture needs to be on the graph.
Use this code to add the purple line and make sure it’s crossing the orange line. Please make sure the lines are positioned the same way it is shown on the picture with the graph.
Use this code on MATLAB and add the purple line.
% Sample data for Diesel and Petrol cars
carPosition = linspace(1, 60, 50); % Assumed positions of cars
% Use the 'seed' function instead of 'rng'
