Abiyote invested $24,500 on January 1, 1994 in the Utopia Fund. On May 1, 1995, his balance was $28,212 and he withdrew $10,000. On December 1, 1995, his balance was $15,892, and he deposited $8,000. On January 1, 1997 his balance was $30,309. (a) Find the annual time-weighted yield for the Utopia Fund for the threeyear period from January 1, 1994 until January 1, 1997. (b) Find an approximate annual dollar-weighted yield received by Abiyote for the three-year period from January 1, 1994 until January 1, 1997 using (2.6.5) (c) (recommended for those with a BA II Plus calculator ) Find the dollarweighted yield received by Abiyote for the three-year period from January 1, 1994 until January 1, 1997, correct to the nearest millionth of a percent. (d) Compare the time-weighted yield experienced by the Utopia Fund and the dollar-weighted yield received by Abiyote from his investment in the Utopia Fund. Discuss why the inequality between them is in the direction it is.

Who is better at multi-tasking? in business, employees are often asked to perform a complex task when their atten-tion is divided (i. e., multi-tasking). human factors (may 2014) published a study designed to determine whether video game players are better than non–video game play-ers at multi-tasking. each in a sample of 60 college stu-dents was classified as a video game player or a non-player. participants entered a street crossing simulator and were asked to cross a busy street at an unsigned intersec-tion. the simulator was designed to have cars traveling at various high rates of speed in both directions. during the crossing, the students also performed a memory task as a distraction. two variables were measured for each student: (1) a street crossing performance score (measured out of 100 points) and (2) a memory task score (measured out of 20 points). the researchers found no differences in either the street crossing performance or memory task score of video game players and non-gamers. “these results,” say the researchers, “suggest that action video game players [and non-gamers] are equally susceptible to the costs of dividing attention in a complex task”

Afirm’s production function is represented by q(m, r) = 4m 3/4r1/3, where q denotes output, m raw materials, and r robots. the firm is currently using 6 units of raw materials and 12 robots. according to the mrts, in order to maintain its output level the firm would need to give up 2 robots if it adds 9 units of raw materials. (a) true (b) false
