Answer:

AR(2) model is not stationary

Explanation:

Given model : Yt = 0.803yt-1 + 0.682yt-2 + ut ---- ( 1 )

ut = noise error process

Aim : Check estimated model for stationarity

<em>step 1 : </em>represent the estimated polynomial of the model ( where: ut ∪ N(o,б^2 ) rewrite equation 1

Yt - 0.803yt-1 - 0.682yt-2 = ut ------- ( 2 )

hence the polynomial can be represented as :

( 1 - 0.803B - 0.682B^2 )Yt = ut

Characteristic of the obtained polynomial can be represented as ;

1 - 0.803λ - 0.682λ^2 - 1 = 0

attached below is the remaining part of the solution

term fixed price contract to build an office tower for $10,000,000. In the first year of the contract Tullis incurs $3,000,000

almond37 [142]

Answer: $750,000

Explanation:

Given that,

Fixed price contract = $10,000,000

Cost incurred in the first year = $3,000,000

Remaining costs to complete = $5,000,000

Tullis billed = $4,000,000 in year 1

Collected by the end of the year = $3,500,000

Percentage of work completed = $\frac{Expenditures\ Incurred\ from\ Inception\ to\ Date}{Total\ Estimated\ Costs\ for\ the\ Contract}$

= $\frac{3}{8} \times 100percent$

= 37.5%

Revenue recognized = 37.5% of $10,000,000

= $3,750,000

Income recognized = Revenue recognized - Cost incurred in the first year

= $3,750,000 - $3,000,000

= $750,000

An internet company gives their old computer system to the computer science

Elanso [62]

Answer:

Explanation:

The formula for GDP is

GDP = C + I + G + NX

C = consumption

I = Investment by business and household purchases by individuals

G = Government Expenditures

NX = foreign trade.

The first thing you can do is knock out foreign trade.

I think you can dispense with Government expenditures as well all though a school is an arm of government.

I think investment is what you have to look at carefully because it does include charitable organizations. We'll come back to this.

Consumption is what it sounds like it sounds.

You can't answer this in any other way than to know how the company writes it off. It is an asset that goes from some value to 0. It no longer exists on their books. So it decreases their assets. It is balanced on their books by calling it an expense I think and that further has impact on their books.

So they are decreasing their value (albeit by a small amount -- they've already bought new computers).

I'm not sure about this, but I think what has happened is that the GDP is going to go down. Their investment has decreased by being written off.

The advent of containerization has:

Firdavs [7]

Answer:

The correct answer is letter "E": significantly lowered the costs of shipping goods over long distances.

Explanation:

Containerization is the method of transporting goods in containers. These technique has become standard in freight transport having regulated the dimensions and maximum capacity of materials being moved. One of the big advantages containerization has provided is to transport different materials from different entities all together which implies sharing the costs of the same container, something that lowers the price of the transportation regardless if it is domestic or international.
