Answer:
11.611 +/- 3.013
Explanation:
3 3.5 4 6 7 8 8.5 12.5 15
7 17 19 12 19 22 28 20 28
difference
4 13.5 15 6 12 14 19.5 7.5 13
mean = 11.611
the standard deviation ⇒ 7.611² + 1.889² + 3.389² + 5.611² + 0.389² + 2.389² - 7.889² + 4.111² + 1.389² = 57.927 + 3.568 + 11.485 + 31.483 + 0.151 + 5.707 + 62.236 + 16.9 + 1.929 = 191.386/9 = √21.265 = 4.611
standard deviation = 4.611 1.918
confidence interval = mean +/- [(standard deviation/√9) x 1.96]
11.611 + [(4.611/3) x 1.96] = 11.611 + 3.013
11.611 - [(4.611/3) x 1.96] = 11.611 - 3.013
The shift to steam power contributed to the growth of cities in many way. Firstly, it provides a continuous source of power to industries, which leads to high level of productivity. The availability of jobs in the industries makes the people in the rural areas to migrate to the cities in search of greener pastures. Steam power also created a new and efficient means of transportation which make it possible to move people and goods over long distances in record time.
Answer:
The correct answer is $83230
Explanation:
Solution
Given that:
The Present worth of geometric series is shown below
= A *[1 - (1+g)^n /(1+i)^n] / (i-g)
Now,
The present cost of worth from EOY 5 to EOY 13 at EOY 4 = 7000 *[1 - (1+0.12)^9 /(1+0.15)^9] / (0.15-0.12)
Thus,
= 7000 *[1 - (1.12)^9 /(1.15)^9] / (0.03)
Which is,
= 7000 * 7.0572647
= 49400.85
Now, The NPW of all costs = 35000 + 7000*(P/A,15%,4) + 49400.85*(P/F,15%,4)
= 35000 + 7000*2.854978 + 49400.85*0.571753
= 83229.93
Therefore the sound improvement better result in a net present worth profit of how much to negate the costs is $83229.93 or 83230
Note: EOY = End of year.
The Etruscans developed a special sophistication in casting and engraving on <u>bronze.
</u>The Etruscans were an ancient culture that was located in central and northern Italy. They were very famous for their art, especially for bronze casts and engravings that are an important archaeological relic even today. They weren't the first nation to do this type of art, however, they were the best.<u>

Explanation:
13,200 Rent prepaid on January 1 for 1 year
÷ 12 Months
$ 1,100 Rent expense per month
Thus, $1,100 Rent expense per month
× 7 Months
$7,700 Rent expense for January through July
At July 31, Aiden's Tavern should record $ 7700 of rent expense.
