(b) below is a scatterplot of the natural logarithm of cell phone subscribers vs. year. this relationship is clearly more linear that the one above. does this suggest that the relationship between cell phone subscribers and year can be modeled by an exponential function or by a power function? explain. (c) computer output from the regression of ln (cell phone subscribers) vs. year is given below. use it to predict the percentage of people in the world who were cell phone subscribers in 2005.

Answer:

Explanation:

A)

The regression equation is,

ln(Cell Phone Subscribers) = -820.894 + 0.411704 Year

or,

Percent of Cell Phone Subscribers = exp(--820.894 + 0.411704 Year)

For the year 2005,

Percent of Cell Phone Subscribers = exp(--820.894 + 0.411704 * 2005)

= 96.79%

B)

P-value for the significance of the slope is very low (0.000). Thus, the model is statistically significant and the prediction of the model is highly reliable.

A firm with $900,000 in sales, cash on hand of $1,150,000, liabilities of $400,000 and total assets of $2 million has a total as
notsponge [240]

Answer:

0.45

Explanation:

Total Asset turnover is the relationship between the total asset and the total sales.  It measure the turnover generated by assets and shows how fully a company is utilizing its assets.

It is calculated as  Net Sales / Average Total asset.

Average total asset is calculated as  Asset at Beginning  + Asset at closing / 2

Applying the formula

The total sales = $900,000  while the total asset is $2, 000,000

$900,000/$2,000,000 =  0.45

Note: The beginning and closing Asset were not given so $2,000,000 is regarded to as the average asset.

Many firms include on their employment applications a box that job seekers are asked to check if they have ever been convicted o
maria [59]

Answer:

These two statements are correct:

A. Potential employers may have believed that those with black-sounding names had completed less education.

African Americans on average have less rates of graduation from tertirary education than White Americans.

This situation might lead some employers to develop streotypes about African Americans being less educated, when it is clearly an error, and unfair, to reject a potential employee because of stereotyping instead of making an individualized analysis of his or her abilities.

D. Hiring firms may have believed that those with black-sounding names were more likely to have a criminal conviction.

African Americans on average are incarcerated more often than other ethnic groups in the US. The reasons for this are complex but poverty and racial discrimination are two big factors. This situation causes some employees to develop streotypes, leading to unfair situations as described in the first answer.

Corbel Corporation has two divisions: Division A and Division B. Last month, the company reported a contribution margin of $49,3
Leokris [45]

Answer:

Common Fixed Expense is $28,600

Explanation:

Given,

Contribution of Division A = $49,300

Computing Contribution of Division B as:

Contribution = Sales × Contribution margin ratio

where

Sales is $242,000

Contribution margin ratio is 25%

So,

Contribution = $242,000 × 25%

= $60,500

Therefore, Total Contribution is :

= $49,300 + $60,500

= $109,800

Computing Income before Common Fixed Expense as:

Income before Common Fixed Expense = Total Contribution -  Traceable fixed expenses

= $109,800 - $51,600

= $58,200

Computing Common Fixed Expense as:

Common Fixed Expense = Income before Common Fixed Expense - Income after Common Fixed Expense (Net Income)

= $58,200 - $29,600

= $28,600

densk [106]

Answer:

The amount recognized as revenue in the first year is $14000

Explanation:

The reason is that Maas LLP has no post sales services agreement to Sunny Dale which means he owes him nothing in benefits so the amount received as a whole is license fee only which gives Sunny Dale the right to use the software. So the amount received must be recognized as revenue for the year.
