The following model for learning a concept over a set of lessons identifies four states of learning: I = ignorance, E = exploratory thinking, S = superficial understanding and M = mastery. If now in state I, after one lesion you have 50% chance of still being in I and 50% chance of being in E. If now in state E, you have 25% chance of being in I, 50% in E, and 25% in S. If now in state S, you have 25% chance of being in E, 50% in S, and 25% in M. If in M, you always stay in M. (a) Write out the transition matrix for this Markov chain with the absorbing state as the first state. (b) Compute the fundamental matrix N. (c) What is the expected number of rounds until mastery is attained if currently in the state of ignorance?

Two language majors, anna and megan, took exams in two languages. anna scored 85 on both exams. megan scored 74 on the first exam and 85 on the second exam. overall, student scores on the first exam had a mean of 82 and a standard deviation of 4, and the second exam scores had a mean of 71 and a standard deviation of 13. a) to qualify for language honors, a major must maintain at least an 85 average across all language courses taken. so far, which of anna and megan qualify? b) which student's overall performance was better?

Jenny invests $2,000 at an interest rate of 5%. the amount of money, me, in jenny's account after tyears can be represented using the equation ma-2000(1.05). if jenny would have invested the same amount of money at the same interest rate four years ago, the equation representing the amount of money mo. in her account would be represented using the equation! mg = 2000(105)*** which of the following is equivalent to mp? 2000(105) om- 1.05 2000(1.05) mo 1059 mp-2000(1.05) (105) mp - 2000(1.05) + (1.05)
