Answer:
Assume that a context switch takes T time. Suggest an upper bound (in terms of T) for holding a spinlock. If the spinlock is held for any longer, a mutex lock (where waiting threads are put to sleep) is a better alternative.
Explanation:
The top limit is to be twice the value of (2xT). Holding the spinlock for a longer time, it will be necessary to put the thread to sleep and get a context switch, so one process awakes the sleeping thread without the need of a second context switch.
In process synchronization, cooperating process can affect or be affected by other processes executing in the system, either directly share a logical address space, both code and data, or be allowed to share data only through files or messages, although concurrent access to shared data may result in data inconsistency. But there are several mechanisms to help the orderly execution of cooperating processes that share a logical address space, so that data consistency is kept.
,Answer: a. 9,450 units
Explanation:
You need to find the weighted average contribution margin for both products.
Product A
Weighted average contribution margin = Contribution margin * Units sold / Total units sold
= 34 * 7,600 / (7,600 + 2,400)
= $25.84
Product B
= 59 * 2,400 / 10,000
= $14.16
Breakeven point in units = Fixed costs/ (Weighted average contribution margin of both A and B)
= 378,000 / (25.84 + 14.16)
= 9,450 units
Current Income. Preferred stocks are a hybrid type of security that includes properties of both common stocks and bonds. One advantage of preferred stocks is their tendency to pay higher and more regular dividends than the same company's common stock. Preferred stock typically comes with a stated dividend.
Answer:
In that situation, the demand of the Milk tea will fall.
Explanation:
In businesses subtitles are the type of products that serve a similar purpose but generally less favorable. You use substitutes as a second product when you somehow cannot use the first/main product.
In the example above,
Let's say that Coffee is people's favorite beverages. They like it better than milk tea. But, if they don't have enough money to buy their favorite coffee, they sometimes have to exchange it and settle with milk tea.
When weather increases the harvest of the coffee bean crop, the price of coffee will most likely fall down due to the abundance in resource.
When this happen, there will be lesser people who use the substitute product. in the end, the demand for the milk tea will fall.
