Answer:
A portfolio consists of 40% in Security A and 60% in Security B. The covariance matrix for A is 144, 225; for B is 225, 81. The standard deviation for the portfolio is <u>12.7</u>
Option D is correct
Explanation:
Wa: 0.4
Wb: 0.6
a^2: 144
b^2: 81
Cov(a,b): 225
Portfolio Variance:
: (0.4*0.4*144) + (0.6*0.6*81) + (2*0.4*0.6*225)
: 160.2
Portfolio Standard Deviation: 12.7

The spa package budget will be achieved in six weeks, thereby qualifying as a short term goal. Long-term goals contrast short term goals as they take longer than one year to achieve.
Answer: Charge a lower price after half-time
