Answer:
Standard deviation = 47.69% (Approx)
Explanation:
Given:
Portfolio of Apple stock w1 = 25% = 0.25
Portfolio of Tesla stock w2 = 75% = 0.75
Standard deviation return Apple σ1 = 35% = 0.35
Standard deviation return Tesla σ2 = 60% = 0.60
Correlation coefficient ρ12 = 0.22
Find:
Standard deviation
Computation:
Standard deviation = √w1²σ1² + w2²σ2² + 2w1σ1w2σ2ρ12
Standard deviation = 0.4769
Standard deviation = 47.69% (Approx)
Answer:
Explanation:
When Leverett's exports became less popular, its savings, Y-C-G does not change. Reason being that, it is assumed that Y depends on the amount of capital and labour, consumption depends only on disposable income and government spending is a fixed extrinsic variable.
Since investment depends on interest rate, and Leverett is a small open economy that takes the interest rate as given, thus investment also does not change . Neither does net export change (This is shown by the S-I curve in the attachment).
The decreased popularity of Leverett's exports leads to an inward shift of the net export curve inward. At the new equilibrium,net exports remains unchanged, though the currency has depreciated.
Leverett's trade balance remained the same, despite the fact that its exports are less popular, this is due to the fact that the depreciated currency provides a stimulus to net exports which overcomes the unpopularity of its exports by making them cheaper.
b. Leverett's currency now buys less foreign currency, thus traveling abroad becomes more expensive. This is an instance showing that imports (including foreign travel) have become more expensive- as required to keep net exports unchanged in the case of decreased demand for exports.
Answer:
the gift shop must recognize 31 days of accrued interest payable, total interest = principal x interest rate x time passed
= $50,000 x 12% x 31/365 days = $509.59
the adjusting entry should be:
December 31, accrued interest on note payable
Dr Interest expense 509.59
Cr Interest payable 509.59
Answer:
Technology is defined by how people use scientific knowledge, and not only does scientific knowledge constantly change, but the way we use it is also constantly changing.
Emerging technologies refers to a new technology or technological innovations. The problem is that what can be considered new and how fast will it become obsolete? Our world is changing so fast, that current technology will be obsolete in just a few months, or maybe a year from now.
Because new technologies become old too fast, it is very difficult to identify them before they are no longer an innovation. Only those technologies that become mainstream can be clearly identified as emerging technologies, e.g. the iPhone was considered an emerging technology in 2007 and even though the first iPhone is obsolete now, it became mainstream technology.
