Answer:
Option A is the cheapest.
Explanation:
Giving the following information:
The engineering department estimates costs of $450,000 for the first year. It is estimated that if process and plant alterations are made, the waste treatment cost will decline $43,000 each year. As an alternative, a specialized firm, Hydro-Clean, has offered a contract to process the waste liquids for 15 years for $225,000 per year.
We need to use the following formula and chose the smallest net present value:
NPV= Io +∑ [Cf/(1+i)^n]
Option A:
Io= 407,000
Year cost= 43,000
NPV= 734,061
Option B:
Yearly cost= 225,000
NPV= 1,936,368
Answer:
The total of the combined salaries of all the employees at Company E after July 1 last year was 110% of that before July 1 last year.
Explanation:
If we use numbers, as example, we can get that:
Before July 1st Company E' s employes had in average salary of $100.000 (example).
If, after the decreased of employees, average salary was 10% percent more, that means that:
- $100.000 x 10%= <u>$10.000
</u>
So, total of combined salaries after decreased was
- $100.000+$10.000= $110.000
$110.000 is the 110% of the average salary before decreased because:
- <u>$110.000/100.000 = 110%</u>
Answer:
<u>Thus Calculation of September Cash Receipts is as follows:</u>
September Sales ( $170,000 × 30%) = $51,000
August Sales ( $150,000 × 55%) = $82,500
Total = $133,500
Explanation:
September cash receipts will include the following :
- 30% of September Sales
- 55% of August Sales
<u>Thus Calculation of September Cash Receipts is as follows:</u>
September Sales ( $170,000 × 30%) = $51,000
August Sales ( $150,000 × 55%) = $82,500
Total = $133,500
The answer is<u> "2. cluster sampling."</u>
Cluster sampling alludes to a kind of sampling technique . With cluster sampling, the scientist partitions the populace into isolated gatherings, called groups. At that point, a basic random sample of clusters is chosen from the populace. The analyst leads his investigation on information from the inspected clusters.
Contrasted with simple random sampling and stratified sampling, cluster sampling has points of interest and disservices. For instance, given equivalent example sizes, group testing normally gives less accuracy than either simple random sampling or stratified sampling. Then again, if travel costs between clusters are high, cluster sampling might be more practical than alternate strategies.
