Here shows the returns of firms X and Y under different states of economy. Which of the following results regarding the (expected return, risk) of the two assets is correct?[img=436x336]18032c62324d198.png[/img]
A: X (30%, 10%), Y (20%, 20%); Y is riskier
B: X (10%, 10%), Y (10%, 11%); Y is riskier
C: X (10%, 25.30% ), Y (10%, 12.65% ); X is riskier
D: X (10%, 12.30% ), Y (20%, 20.65% ); X is riskier
A: X (30%, 10%), Y (20%, 20%); Y is riskier
B: X (10%, 10%), Y (10%, 11%); Y is riskier
C: X (10%, 25.30% ), Y (10%, 12.65% ); X is riskier
D: X (10%, 12.30% ), Y (20%, 20.65% ); X is riskier
举一反三
- 已知intx=10,y=20,z=30;以下语句:if(x A: x=10,y=20,z=30 B: x=10,y=20,z=10 C: x=20,y=30,z=10 D: x=20,y=30,z=20
- 已知 x = 10, y = 20, z = 30; 以下语句执行后x，y，z的值是：if (x = 20) z = x; y = z; A: x = 10, y = 20, z = 30 B: x = 10, y = 10, z = 10 C: x = 20, y = 20, z = 20 D: x = 30, y = 30, z = 30
- 已知int x=10, y=20, z=30;，程序段if (x>y) z=x;x=y;y=z;执行后x、y、z的值是（ ）。 A: x=20, y=10, z=10 B: x=20, y=30, z=30 C: x=20, y=30, z=10 D: x=20, y=30, z=20
- 下面代码的输出结果是 def exchange(a,b): a,b = b,a return (a,b) x = 10 y = 20 x,y = exchange(x,y) print(x,y) A: 20 10 B: 20 20 C: 10 20 D: 10 10
- 设有变量定义：int x=10,y=20,z=30;则以下语句执行后x,y,z的值是______。 A: x=20,y=30,z=20 B: x=10,y=20,z=30 C: x=20,y=10,z=10 D: x=20,y=10,z=0
