Answer:

A) 1.111

B) 0.889

Explanation:

given data :

outer diameter of connecting rods = 1 ± 0.01 inch

sample mean outer diameter = 1.002 inches

standard deviation = 0.003 inches

A) Calculating the Cp of the process

mean = 1.002

Standard deviation = 0.003

LSL = 1 - 0.01 = 0.99

USL = 1 + 0.01 = 1.01

Cp = \frac{USL - LSL}{6 * STANDARD DEVIATION} =  \frac{1.01-0.99}{6*0.003} = 1.111

B) calculate Cpk

mean = 1.002, LSL = 0.99, USL = 1.01 , deviation = 0.003

Cpk = min[\frac{mean-LSL}{3* deviation} , \frac{USL- mean}{3*deviation} ]

       = min [(0.012/0.009) , (0.008/0.009) ]

       = min [ 1.333, 0.889 ]

hence Cpk = 0.889

aniked [119]

Answer:

a. Cost of goods sold = Sales - Gross profit

= $416,720 - $242,950

= $173,770

b. Direct materials cost = Materials purchased -Indirect materials - Materials inventory, end of period

= $128,350 - $45,220 - $17,090

= $66,060

c. Direct labor cost =Total manufacturing costs for the period - Direct materials cost - Factory overhead

= $239,610 - $66,060 - ($90,430 + $45,220 + $13,750)

= $239,610 - $66,060 - $149,380

=$239,610 - $215,440

=$24,170

Yanka [14]

Answer:

Break-even units = 66.67 units

Explanation:

<em>Break-even point is the level of activity that achieves no profit or loss. At this level profit is zero because the the total revenue is equal to total cost.</em>

<em>The break-even point is calculated as </em>

<em>Units to achieve target profit = (Total general fixed cost for the period + target profit)/ contribution per unit</em>

Contribution per unit = Selling Price - Variable cost

Contribution per unit = 15- (1+3+0.50) = 10.5

Fixed cost = 500 +( 50× 4) = 700

So the units requited to achieve break-even point:

Break-even point =  700/10.5

                            = 66.67 units

liraira [26]
Given:
net sales = 53,404,000,000
Average total assets = 16,302,000,000

Total asset turnover is calculated by divided net sales by the average total assets.

Total asset turnover = net sales / average total assets 
T.A.O = 53,404,000,000 / 16,302,000,000
T.A.O = 3.2759 OR 3.3

The total asset turnover indicates the company's ability to efficiently deploy its asset in generating revenue.
