想請問這題給的答案是對的嗎？因為題目裡有寫明security X跟security Y的權重分別是70%跟30%，但是到了答案裡又變成了60%跟40%，有點困惑🥲🙏

收益率 A Ecr × (70%) 14% Y (30%) 10% 4. You are considering investing $1,000 in a complete portfolio. The complete portfolio is composed of Treasury bills that pay 5% and a risky portfolio, (P, constructed with two risky securities, X and Y. The optimal weights of X and Y in P are 70% and 30%, respectively. X has an expected rate of return of 14%, and Y has an expected rate of return of 10%. The dollar values of your positions in X, Y, and Treasury bills would be and , respectively, if you decide to hold a complete portfolio that has an expected return of 8%. Treasury the $110 $1000 profoliots a f .08(1000)=F(.05)+(1000 - F)[.6(.14)+.4(.10)] F = 595 X = (1,000-595)(.6)=243 Y = (1,000-595)(.4)=162 7-175% P X-1 14% Y- 10% □

證明 f⁻¹(f(x)) = x , f(f⁻¹(x)) = x 是成立的

這兩題該怎麼寫

5. Suppose that a reaction C2H6C2H4+H2 is believed to occur by the mechanism: 1. C2H6-2CH3 2. CH3+ C2H6 CH4+ C2H5 ->> 3. C2H5 C2H4+H 4. C2H6+H→C2H5+H2 5. 2 C2H5 C4H10 . Apply the steady-state treatment to C2H5 CH3 Hand obtain an expression for the overall rate. 6. The reaction between chlorine and chloroform in the gas phase follows the stoichiometric equation CHC13 C12 CCl4 + HCl It is believed to occur by the mechanism Cl₂+hv 2C1 Cl+CHCl3 HCl + CC13 CC13 C12 CCl4 + Cl 2C1→Cl₂ Assume that the steady-state treatment can be applied to C1,CC13 and obtain an expression for the overall rate.

41 M In Fig. 28.31, a metal wire of mass m = 24.1 mg can slide with negligible friction on two horizontal parallel rails separated by distance d=2.56 cm. The track lies in a vertical uniform mag- netic field of magnitude 56.3 mT. At time t = 0, device G is con- nected to the rails, producing a constant current i = 35.0 mA in the wire and rails (even as the wire moves). At t = 61.1 ms, what are the wire's (a) speed and (b) direction of motion (left or right)? d m B FIGURE 28.31 Problem 41.
