Consider two risky securities with returns K1 and K2 given by Scenario Probability K1 K2 w(1) 0.5 10% 7% w(2) 0.5 12% 10% Calculate Cov(K1;K2) and Cov(k1; k2).
Suppose K1 and K2 have the following distribution: Scenario Probability return K1 return K2 w(1) 0.3 -10% 10% w(2) 0.4 0% 20% w(3) 0.3 20% -10% (a) Find the risk of the portfolio with w1 = 30% and w2 = 70%. (b) Find the risk of the portfolio with w1 = 50% and w2 = 50%. (c) Which of the portfolios above (in part (a) and (b)), has higher expected returns?
Thank You & Thumps Up.
K1,K2,B,M is not given. Can you solve without plugging in these
values. I mean just the general form of the equation that works
with any of those values.

Two springs, with force
constants k1=150N/m and k2=235N/m, are connected in series
Two springs, with force constants ki = 150 N/m and k2 = 235 N/m, are connected in series, as shown in (Figure 1). Part A When a mass m = 0.60 kg is attached to the springs, what is the amount of stretch, ? Express your answer to two significant figures and include appropriate units.

1. Springs and a mass are attached to a rigid bar, as shown in Fig 1. The hinges are free to rotate. 0 denotes the rotational angle of the rod, and 0-0 when all springs are not stretched. The mass of the bar and the size of the mass are negligible. Neglect gravitational force, and assume 0 is very small. 1) Derive the equation of motion for this system with Lagrange's method. (20pt) 2) Find the natural frequency of the...
