Answer:

The answer is "\frac{2}{15}" .

Explanation:

\to x = 0, 1, 2, 3, 4, 5\\\\\to p(x) \ for \ x  \ =   0, 1, 2, 3, 4, 5 = 0\\\\ \to c, 2c, 3c , 4c, 5c = 1\\\\\to 0 + c + 2c + 3c + 4c + 5c = 1\\\\\to 15c = 1\\\\\to c = \frac{1}{15}\\

\to p(x) \ for \ x  \ =   0, 1, 2, 3, 4, 5 = 0\\\\ \to \frac{1}{15}, \frac{2}{15}, \frac{3}{15}, \frac{4}{15}, \frac{5}{15}  

\to P(X=2)=\frac{2}{15}

Luzent corporation has two​ departments, small and large. central costs could be allocated to the two departments in various way
Masteriza [31]
<span>$19,200 If the $64,000 is to be allocated on the basis of the number of employees, then let's see how many employees we have. The large department has 1,120 employees and the small department has 480. It would make sense to allocate the same amount of cash per employee, so we have 1,120 + 480 = 1,600 total employees. So the amount per employee is $64,000 / 1,600 = $40 per employee. So the amount allocated to the small department should be: $40 * 480 = $19,200 So $19,200 is the amount to allocate to the small department.</span>

lidiya [134]

Answer:

PV= $529,700.71

Explanation:

Giving the following information:

Cash flow= $50,000

the number of years= 20

Interest rate= 7%

First, we need to calculate the future value of the cash flows. We will use the following formula:

FV= {A*[(1+i)^n-1]}/i

A= annual pay

FV= {50,000*[(1.07^20)-1} / 0.07

FV= $2,049,774.62

Now, we can calculate the present value.

PV= FV/(1+i)^n

PV= 2,049,774.62/1.07^20

PV= $529,700.71

4) Suppose that when the price of hamburgers increases, the Ruiz family increases their purchases of hot dogs. To the Ruiz famil
BigorU [14]

Answer:

D) hamburgers and hot dogs are substitutes.

Explanation:

Option A is incorrect. When the price of one good increases, the demand for other good decreases. It is called complementary goods. In this question, due to the increase in the price of hamburgers, the Ruiz family started taking hot dogs. Therefore, hot dogs price is not increasing. Therefore, it is a substitute good. Substitute goods state that the increase in the price of one good leads to the increase in demand for another good. Therefore, option D is correct.

Normal goods and inferior goods are related to income, so those are not answers.

Darina [25.2K]

Answer:

$4,412

Explanation:

If the company estimates that $4,412 of accounts receivables will be uncollectible, then it must record that number under the Allowance for Bad debts Account.

That account started the year with a $3,284 balance, it decreased by $1,826 (debt written off), and then must be adjusted by crediting $2,954 so its balance = $4,412 on December 31.
