I have to be leaving soon. I would love to help you at the moment but I can't. :(

michele_laino · Answer

questions #18 #19
we have to apply this formula:
$v(t)=-0.092+9.925\cdot t$
please replace $t$ with $0.3$ and subsequently with $15$

michele_laino · Answer

for question #17 
you have to make a diagram, reporting along the x-axis the values of time, and along the y-axis the differences between the corresponding predicted value and the experimental value

ok i got -0.027 for #17

howard-wolowitz · Answer

t = 0.3

michele_laino · Answer

in order to make the residual plot you have to repeat such computation for all the remaining values of $t$, namley, for $t=0,0.4,0.6,0.8$

howard-wolowitz · Answer

ok give me a minute im doig it now

howard-wolowitz · Answer

well one thing for sure is that they are all negative so

michele_laino · Answer

it is possible, at the moment I did not such computation

howard-wolowitz · Answer

then what did you get for each one
