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}

scoray [572]

Answer:

The correct answer is C. Is top management committed to the study?

Explanation:

Market research is the process that includes the actions of identification, collection, analysis and dissemination of information with the purpose of improving marketing decision making. Its implementation occurs basically for two reasons:

1. to solve problems, for example, determine the potential of a market.

2. to identify problems, for example, to know why a product does not have the expected consumption. In essence, it seeks to meet the customer thus complying with the first premise of marketing.

That is why managers and researchers continually focus on the search for those practices that will allow them to improve the organization and direction of their processes and therefore increase their likelihood of success.

A company has two departments, Y and Z that incur wage expenses. An analysis of the total wage expense of $19,000 indicates that
Xelga [282]

Answer:

Departmental wage expenses for Dept. Y = 8,750 and Dept. Z = 10,250.

Explanation:

Direct wages of Y and Z sum 2,000 + 3,500 = 5,500. The remaining expenses are the difference between total wage expense and direct wage expenses. That means indirect expenses are 19,000 - 5,500 = 13,500. These has to be allocated half for each department.

  • Dept Y expense is 2,000 + 13,500/2 = 2,000 + 6,750 = 8,750
  • Dept Z expense is 3,500 + 13,500/2 = 3,500 + 6,750 = 10,250

At a sales volume of 30,000 units, Carne Company's total fixed costs are $30,000 and total variable costs are $45,000. The relev
Anna [14]

Answer:

$2.25

Explanation:

sale volume of company = 30,000 unit

total fixed cost are = $30,000

total variable cost $45,000 for 30,000 unit

1 unit = 45000/30000 =  $ 1 . 5

for the sale of 40,000 unit

the  total expected cost

    = Fixed cost + Variable cost

      = $30,000 + 40,000×$1.50

      = $30,000+$60,000

     = $90,000

Cost per unit:

 = $90,000/40,000

=  $2.25
