Answer: Option (B) is correct.
Explanation:
Correct option: Decreasing marginal product.
Marginal product is the change in the level of output, when there will be an extra input employed in the production of a certain commodity.
So, Marginal Product = 
Where,
Q = Output
I = Input
Marginal product of 1st bag = 500
Marginal product of 2nd bag = 
= 300
Marginal product of 3rd bag = 
= 100
∴ From the above calculations, we can seen that as we employed one more bag of seeds as a result marginal product goes on diminishing.
Hence, Joan's production function exhibits decreasing marginal product.
Answer:
Set.
Explanation:
Closure property in algebra asserts that 'when an operation(multiplication, addition) takes place among the members of a set, the result produced would surely be a member of that same set.' For example, if we add or multiply two real numbers(members of the same set), the result would be a real number for sure(a member of the same set). It implies that 'real numbers are closed under multiplication and addition.' While if I subtract two real numbers, I may or may not get a real number. Thus, the real numbers are closed under subtraction.
Answer:
Prior principal approval must be obtained and a copy of the speech must be retained in your firm's Office of Supervisory Jurisdiction
Explanation:
Because the speech is to be givento 35 attendees, it is under the Retail Communication. Every speech should be honest and of good taste; and the speech must be informational, but far from promotional.
It is not required that the speech content has to be pre-filed with the SEC. A copy must be kept a period of f 3 years for inspection by FINRA examiners. The speech script would be kept on file in the firm's supervisory compliance office that is the Office of Supervisory Jurisdiction.
