The portfolio beta would simply be the summation of the
weighted average of each beta.
Where weighted average of each beta is calculated as:
Stock weighted average = Stock proportion * Individual
beta
Therefore,
Stock A beta weighted average = 0.2 * 0.4 = 0.08
Stock B beta weighted average = 0.3 * 1.2 = 0.36
Stock C beta weighted average = 0.25 * 2.5 = 0.625
Stock D beta weighted average = 0.25 * 1.75 = 0.4375
The summation of all betas yield the overall portfolio
beta:
Portfolio beta = 0.08 + 0.36 + 0.625 + 0.4375
<span>Portfolio beta = 1.5025 ~ 1.5</span>
Answer:
A. 0.9x + 0.3y ≤ 10,000
Explanation:
Given
oil based plant
water based plant
The data can be represented in tabular form as:

Considering only A, we have the following constraints:


Since the company currently has 10000 of A.
The above constraint implies that, the mixture cannot exceed 10000.
So, we have:

<em>Hence, (A) is correct</em>
