Citrus2011 [14]

Answer:

internal rate of return is 20.463%

Explanation:

given data

Year   Cash Flow

1         $48,000

2         $46,000

3          $41,000

equipment cost = $95,000

to find out

Determine the internal rate of return

solution

we consider here  internal rate of return  is x

so we can say present value of inflows = present value of outflows

equate here

$95000 = \frac{48000}{(x)} +\frac{46000}{(x)^2} +\frac{41000}{(x)^3}  

solve it we get

x = 20.463 %

so internal rate of return is 20.463%

In Ricci v. DeStefano, Ricci, a white firefighter, took and passed the City of New Haven firefighter's test, required of all app
vfiekz [6]

Answer:

The correct answer is A. In Ricci v. DeStefano, the Supreme Court ruled that an employer may not simply disregard a test based on unwanted results unless the test is shown to be biased or deficient.

Explanation:

Ricci v. DeStefano is a Supreme Court ruling of 2009, after a lawsuit by nineteen firefighters who claimed to have been discriminated against in terms of career development.  They denounced that they had been discriminated after having passed the admission tests and still had not been promoted, since no African-American candidate had passed the tests. They also denounced that they had not been promoted because the Fire Department did not want to promote a group of new recruits without including within it any member of racial minorities.

Finally, the Supreme Court established that said procedure violated Title VII of the Civil Rights Act of 1964, since in the case equal access to employment was not guaranteed (in this case, favoring minorities over white firefighters), for set different demands for purely racial reasons.
