Answer:
12.00%
Explanation:
As per the given question the solution of standard deviation of a portfolio is provided below:-
Standard deviation of a portfolio = √(Standard deviation of Product 1)^2 × (Weight 1)^2 + Standard deviation of Product 2)^2 × (Weight 2)^2 + 2 × Standard deviation of product 1 × Standard deviation of product 2 × Weight 1 × Weight 2 × Correlation
= √(0.165^2 × 0.6^2) + (0.068^2 × 0.4^2) + (2 × 0.6 × 0.4 × 0.165 × 0.068 × 0.7)
= √0.009801 + 0.0007398 + 0.00376992
= √0.01431076
= 0.119628592
or
= 12.00%
So, we have calculated the standard deviation of a portfolio by using the above formula.
Answer:
C. Listeria monocytogenes
Explanation:
Meningitis is an infectious disease caused by the infection of meninges by virus or bacterial. This can lead to confusion, vomiting, depression etc.
When food that has been contaminated by a pathogen called listeria monocytogenes is consumed, it can develop into meningitis.

Answer:
1.Occupancy days $3,760
Electrical costs $10,528
Variable cost=2.80
Fixed cost=$650
2. Seasonal factors
Systematic factors
Number of days
Explanation:
1.Calculation using high and low method for both Occupancy days and Electricity cost
Occupancy Electrical
Days Costs
High activity level 4,410 12,998
Low activity level 650 2,470
Change 3,760 10,528
Calculation for Variable cost of electricity per occupancy-day.
Using this formula
Variable cost= Electricity cost/Occupancy days
Let plug in the formula
Variable cost=10,528/3,760
Variable cost=2.80
Calculation for Fixed cost of electricity per month
Fixed cost=2,470-(650*2.80)
Fixed cost=2,470-1,820
Fixed cost=$650
2. Factors that are likely to affect the variation in electrical costs from month to month will include the following:
Seasonal factors
Systematic factors
Number of days
Seasonal factors can either be winter or summer.
Systematic factors include either having guests, To switch off fans as well as lights.
Number of days are days that are present in a month.
