Answer:
Ten pounds of chicken to trade for at least <u>40</u> pounds of vegetables but not more than<u> 50</u> pounds of vegetables
Explanation:
Vegetables Chicken Trade Off Ratio
John 40 10 4:1 (40/10) or 1:0.25 (10/40)
George 25 5 5:1 (25/5) or 1:0.20 (5/25)
John has comparative advantage in Chicken and George has comparative advantage in Veggies because :
- John's chicken opportunity cost, in veggies < George (4<5). George's veggies opportunity cost, in chicken < John (0.20<0.25).
- George is more (5X) productive in veggies than chicken, than John (4X). John is less unproductive in chicken than veggies (1/4th), compared to George (1/5th).
So, John will sell Chicken to George & George will sell veggies to John. Gains from trade are when each get trade ratio better than their their own trade off ratio.
- It implies: John gets >' 4 pounds veggies per chicken pound' and George gets > '0.20 pound chicken per veggie pound'.
- Unitary method:- '1chicken : 4veggies' = '10chickens : 40veggies' and '0.20chicken : 1veggie' = '10chickens : 50 veggies' .
Answer:
A. standard deviation = $500, expected return = $5,000
Explanation:
For analysis which investment involved the least amount of risk we need to determine the coefficient of variation i.e. shown below:
As we know that
Coefficient of variance = standard deviation ÷ expected return
A = $500 ÷ $5,000 = 0.10
B = $700 ÷ $500 = 1.40
C = $900 ÷ $800 = 1.125
D = $400 ÷ 350 = 1.143
As it can be seen that investment A has the leas amount of risk hence, the same is to be considered
The number of available colors is n = 7.
The number of colors that can be selected at a time among the 7 colors is r = 5.
This means that the number of selections of 5 colors from 7 colors at a time is ₇C₅.
By definition,

Answer: The number of color groupings is 21.
