I am attaching both questions for 4 and 5 with the question in the image. thank you. NOTE : So the last person answered this question WITHOUT refencing the answer for whether question 4 or 5 answeres were given, so i am asking for question 5(or the answer for the question that was NOT solved because it was not referenced.) These were the following answers given to me from the last person on bartleby who answered my question without referencing whether it was the answer for question 4 or 5. 1 pass 2 fail 3 fail 4 pass
I need these three parts answered, if you are unable to answer all three parts please leave it for another tutor to answer, thank you.
Keep the same colors the same graph, basically keep everything the same just make the line with a small curve just as shown on the picture Keep everything the same just make the line less curvy please do not change the colors of the line and the circles do not change anything besides the curve of the line. Use this code on MATLAB and fix it. % Sample data for Diesel and Petrol cars carPosition = linspace(1, 60, 50); % Assumed positions of cars % Use the 'seed' function instead of 'rng' seed = 50; % Define your seed here rand('seed',seed); % Assumed CO2 emissions for Diesel and Petrol CO2Diesel = 25 + 5*cos(carPosition/60*2*pi) + randn(1, 50)*5; % Random data for Diesel CO2Petrol = 20 + 5*sin(carPosition/60*2*pi) + randn(1, 50)*5; % Random data for Petrol % Fit polynomial curves with a reduced degree of 2 pDiesel = polyfit(carPosition, CO2Diesel, 2); pPetrol = polyfit(carPosition, CO2Petrol, 2); % Generate points for best fit lines fitDiesel = polyval(pDiesel, carPosition);…
Posted below is a picture of a data table and a diagram of an experiment. In the experiment you rolled a marble down a ruler ramp off the end of a coffee table to observe projectiles and conservation of energy. You do 3 trials for each initial height. Each height is measured in meters. h= initial height of marble off of table Y= height of table off floor X= horizontal distance marble goes from edge of table to where it strikes the floor a) use the table to find information you need to solve for theoretical range and % of error in measured range.
The question and data are in pictures. Please answer properly with each steps and explanation. Best of luck. Thank you so much in advance.
Last person got every single question wrong and didn't include units. Please help.
I need answers to questions 13, 14, and 15 pertaining to the print provided. Note: A tutor keeps putting 1 question into 3 parts and wasted so many of my questions. Never had a issue before until now, please allow a different tutor to answer because I was told I am allowed 3 of these questions.
Don't Use Chat GPT Will Upvote And Give Solution In 30 Minutes Please
please sovle part (I) and give me the formulas used in excel Try to find a result less than 50 for the question
