Answer:
the Expected rate of return will be 8.2%
the variance will be 0.001296
Explanation:
We will calculate the Expected Rate of Return which is the sum of the wieghted return based on their probabilities:
return of 0.15 probability 20% = 0.03
return of 0.07 probability 70% = 0.049
return of 0.03 probability 10% = 0.003
expected return = 0.082 = 8.2%
Now to calculate the variance we do:
∑(rk-ERR)^2 x pk
The sum of the difference between the expected rate and the escenario rate, power two, and multiply by their posibility
the variance will be: 0.001296
D)the desire to get the most for their money.
Answer:
The answer is: B) The statement is false. A decrease in the price of digital cameras would decrease the demand for non-digital cameras, but a decrease in the price of non-digital cameras would not cause the demand for non-digital cameras to decrease.
Explanation:
Suppose we are not currently living in 2019, instead we are back 12 years to 2007 (before the iPhone). Back then , digital cameras were still used by common "unprofessional" users. Digital cameras were an improvement compared to non-digital cameras, so the price of non-digital cameras were much lower than their digital counterparts.
If the price of digital cameras decreased, then the price of non-digital cameras would decrease also. For example, if luxury car companies like Mercedes Benz started selling sedan cars for $20,000, Ford and Chevrolet would be forced to lower the price of their cars since they wouldn't be able to compete with MB at the same price.
But a decrease in the price of non-digital cameras would never decrease their demand. Something else would have caused that decrease. Probably digital cameras became so cheap that everyone could afford one and since they were so much better than non-digital cameras, people simply stopped buying non-digital cameras.
Answer:
Identifying fixed cost and variable cost.
Explanation:
- The behavior cost is those costs that will completely change when there are minute changes in the activity and includes the variable and the fixed costs and the semi-variable costs.
- As an example of the fixed cost is the insurance. While the variable cost is flour for the bakery that produces artisan bread. And that of the semi mixed cost is the cost of the bakery cost and the natural gas.
