It will decrease
because the marginal productivities of workers will decrease. Diminishing marginal product occurs when the
marginal product of an input goes down as the quantity of the input goes up. The transformation in product resulting from
employing one more unit of a particular input for instance, the change in
output when a firm's labor is mark up from five to six units, assuming that the
mass of other product are kept constant is
called The input of marginal product or marginal physical product.
Answer:
GDP for an open economy from the spending approach follows this equation:
GDP = Consumption + Investment + Government Spending + Net Exports (Exports - Imports)
It can also be written as:
GDP = C + I + G + NX (X - N)
The balance of private consumption is simply equal to C, the balance of public spending is G, and the balance of the external sector is net exports or NX.
The answer to the question mentioned above is "the Euro".
Euro is the name of the currency that is used and by 19 members states and 330 million people, though some politicians and economist are calling for its retirement. This is the official currency of the Eurozone.
Answer:
(a) 
(b) 
(c) X=4.975 percent
Explanation:
(a) Find the z-value that corresponds to 5.40 percent
.
Hence the net interest margin of 5.40 percent is 2.5 standard deviation above the mean.
The area to the left of 2.5 from the standard normal distribution table is 0.9938.The probability that a randomly selected U.S. bank will have a net interest margin that exceeds 5.40 percent is 1-0.9938=0.0062
(b) The z-value that corresponds to 4.40 percent is 
The net interest margin of 4.40 percent is 0.5 standard deviation above the mean.
Using the normal distribution table, the area under the curve to the left of 0.5 is 0.6915
Therefore the probability that a randomly selected U.S. bank will have a net interest margin less than 4.40 percent is 0.6915
(c) The z-value that corresponds to 95% which is 1.65
We substitute the 1.65 into the formula and solve for X.
A bank that wants its net interest margin to be less than the net interest margins of 95 percent of all U.S. banks should set its net interest margin to 4.975 percent.
<span>Well practiced activities are most likely to improve when performed in front of an audience. On the flip side, if an activity is ill-practiced, the performer is more likely to flub the performance. But practice enhances performance, and so anyone wanting to demonstrate a good show of something should practice it intently beforehand.</span>
