Answer:

Standard deviation of the portfolio = 70.71%

Explanation:

σP =√(w²A *σ²A) + (w²B*σ²B) +2 (wA*wB*correl. AB)

w = weight of..

Given that;

wA = 50% or 0.5 as a decimal

wB = 50% or 0.5

σA = 40% or 0.4

σB = 20% or 0.2

correl. = correlation = 0.90

σP = √(0.5² * 0.4² ) + (0.5² * 0.2² ) +(2*0.5*0.5*0.90)

σP = √ (0.04 + 0.01 + 0.45

= √0.5

= 0.7071

Standard deviation of the portfolio = 70.71%

Current demand = Average number of  pets per day × estimated percentage

= 74 pets × 60%

=  44.4 per day

Now the capacity required per day would be

= (Current demand per day) ÷ (1 -  capacity cushion percentage)

= 44.2 ÷ (1 - 0.12)

= 50.22 per day
