Try the eigenvalue method on the advection equation du(x, t) _ ou(x, t) = -c- ", əx ? @t 2 € (0,00) (a) what are the time dependent solutions for each eigenvalue of the operator -com? (b) show that there are no eigenfunctions of cha subject to the boundary condition u(0,t) = 0 to conclude that the only solution we obtain from the eigenvalue method is the trivial solution u(x, t) = 0 and that is is impossible to satisfy the any arbitrary initial condition u(x,0) = (c) for what eigenvalues of can do the eigenfunctions satisfy the "boundary" condition lim u(x, t) = 0? 200 unlike the boundary condition from part (b), we do get non-zero solutions here. however, explain why the eigenvalue method does not allow us to write the general solution as linear combinations of solutions un(x, t). ne au ಶಿಲ --m, ze10,) c at дх

Apoll is being conducted at a mall nothingto obtain a sample of the population of an entire country. what is the frame for this type of​ sampling? who would be excluded from the survey and how might this affect the results of the​ survey? what is the frame for this type of​ sampling? a. the frame is people who need new clothes. b. the frame is people who shop at the mall. c. the frame is people who like to shop. d. the frame is the entire population of the country. who would be excluded from the survey and how might this affect the results of the​ survey? a. any person that does not need new clothes is excluded. this could result in sampling bias due to undercoverage. b. any person who does not shop at the mall is excluded. this could result in sampling bias due to undercoverage. c. any person who does not shop at the mall is excluded. this could result in nonresponse bias due to people not participating in the poll. d. there is nobody that is being excluded from the survey.
