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}

A plant manager is attempting to determine the production schedule of various products to maximize profit. Assume that a machine
gulaghasi [49]

Answer: a different product mix, different total profit.

Explanation:

It should be noted that in a situation whereby constraint is binding and a change with regards to the availability that is within the range exist, this will bring about a change in both the product mix and total profit.

With regards to the question, since the machine hour constraint is binding and the original amount of machine hours available is 200 minutes, and the range of feasibility is from 130 minutes to 300 minutes, then it should be noted that the provision of two additional machine hours will result in a different product mix, different total profit.

A machine is available 10 hours a day. Each part takes 90 minutes to fabricate and 10 minutes to setup. 10% of the parts made ar
Kazeer [188]

Answer:

Effectiveness = 0.75

Explanation:

Availability time for a each day = 10 hr = 600 minutes

Total time for fabricating is given as 90 minutes'

Total time to set up one part 10 minutes

Total parts made in each single day 5

Percentage of defective part 10%

Total production time for a single part = setup time  + fabricated time

                                                                 = 10+ 90 = 100 min

Production time for 5 part =5 × 100 = 500 minutes

Total number of defective parts =  10% of 5  =  0.5 parts

Time to replaced defective = 0.5  × 100 = 50 min

Value added time = 500 - 50 = 450 min

Effectiveness  is given as

Effectiveness  = \frac{value\ added\ time}{ total\ time\ taken}

Effectiveness = \frac{450}{600} = 0.75

The following data are for Lily Kay Company. Total sales revenue $250,000 Number of units sold 50,000 units Contribution margin
eduard

Answer:

b. 51,429 units

Explanation:

If x = Number of units

Net Income = Sales Revenue - Variable Cost - Fixed Cost

or

Net Income = Contribution Margin - Fixed Cost

where,

Net Income = $80,000

Contribution Margin per unit = $3.50

Fixed Cost = $100,000

Contribution Margin = Net Income + Fixed Cost

$3.50x = $80,000 + $100,000

$3.50x = $180,000

Dividing the above equation by $3.50 we get

x = $180,000 / $3.50

x = 51,429 units

Hence 51,429 number of units must be sold to generate the net income of $80,000.
