Answer:
No gain or loss.
Explanation:
Given:
Amount of spice mixture = 470 pound
Current price = $2.35 per pound
Future price = $2.73 per pound
Computation:
We know that, Future price of spice mixture is higher than current price of spices.
But contract price is fixed at $2.35.
Therefore, no gain or loss will be recognized.
Answer:
$950
Explanation:
Reserve ratio is defined as the percentage amount of deposit that a bank is instructed by the governing central bank to keep as cash reserve. This is used to control the money supply in the economy as the the check - able amount that are subjected to withdrawal is limited to the funds available after the reserve ratio has been considered.
Workings
New deposit - $10,000
Required reserve ratio - 5%
No existing excess ratio as at the time of deposit.
Reserve ratio - 5%*10000 = 50
Increase in checking account = 1000-50
= $950
Answer:
Having invested $ 300 per month for the past 8 years, the total accumulated investment amount would be $ 28,800 (8 x 12 x 300). Now, having a total amount of $ 43,262, we find an increase of $ 14,462, which corresponds to the interest accumulated during said period. To know the percentage of the increase, we must perform a cross multiplication:
28,800 = 100
14,462 = X
(14,462 x 100) / 28,800 = X
1,446,200 / 28,800 = X
50.21 = X
As we can see, the investment had an increase of 50.21% during these 8 years. Now, the average increase in investment arises from the division of the total percentage of increase by the number of years. So, given that 50.21 / 8 = 6.27, the average annual return rate of this investment is 6.27%.

Answer:
d. It is best measured using the statistic variance inflation factor (VIF).
Explanation:
Multicollinearity is an important issue in multiple regression model, having many independent/ explanatory variables. Multicollinearity is the situation in which two or more independent variables are highly correlated. It is problematic because it increases the standard error of independent variable coefficient & undermines its statistical significance
Variance Inflation Factor [VIF] is a check & corrective measure of multicollinearity.
- VIF as a multicollinearity check : It quantifies the correlation between one explanatory variable with other explanatory variables.VIF = 1 implies there is no multicollinearity (correlation between independent variables); VIF upto 5 implies there is moderate multicollinearity (correlation between independent variables). VIF > 5 implies high multicollinearity (correlation between independent variables)
- VIF as a multicollinearity correction : Calculating
= σ^2 / ![[TSS j (1 - R^2j)]](https://tex.z-dn.net/?f=%5BTSS%20j%20%281%20-%20R%5E2j%29%5D)
; where TSS = total sum of square of variable j , σ^2 = j variance, R^2 j = R^2 from regressing all other independent variable on variable j
