Three instructors in a coordinated course, T1, T2, and T3 evaluates axam papers. T1 evaluates 20% of the exam papers, T2 pevaluates 30% and T3 evaluates 50%. The three theachers make the following proportions of errors (E) while evaluating the exam papers: 0.008, 0.008, and 0.003 respectively. If a randomly selected exam paper has an error (E), what is the probability it is from instructor T1?

Consider the three transactions T1, T2, and T3, and the schedules S5 and S6 given below. Show all conflicts and draw the serializability (precedence) graphs for S5 and S6, and state whether each schedule is serializable or not. If a schedule is serializable, write down the equivalent serial schedule(s). T1: r1(x); r1(z); w1(x); T2: r2(z); r2(y); w2(z); w2(y); T3: r3(x); r3(y); w3(y); S5: r1(X); r2(Z); r1(Z); r3(X); r3(Y); w1(X); c1; w3(Y); c3; r2(Y); w2(Z); w2(Y); c2; S6: r1(X); r2(Z); r1(Z);...

We have three light bulbs with lifetimes T1,T2,T3 distributed according to Exponential(λ1), Exponential(λ2), Exponential(λ3). In other word, for example bulb #1 will break at a random time T1, where the distribution of this time T1 is Exponential(λ1). The three bulbs break independently of each other. The three light bulbs are arranged in series, one after the other, along a circuit—this means that as soon as one or more light bulbs fail, the circuit will break. Let T be the lifetime...

A stock analyst tracks three companies with stock pricesf(t)=40+t+t2 −t3/10, g(t) = 7 + t − t2 + t3/5, and h(t) = 15 + t − t2/2 + t3/10 − t4/200, t months into the year. A monthly buy recommendation is due at the end of August, so t = 8. The analyst believes in ‘momentum investing’ and looks for companies with stock prices that are concave upwards at the time of the recommendation. Which company is recommended? (a) Neither...
