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

Turner, a successful executive, is negotiating a compensation plan with his potential employer. The employer has offered to pay
zzz [600]

Answer:

b. If the employer accepts Turner's counteroffer, Turner will recognize as gross income $55,000 per month [($480,000 + $180,000)/12].

Explanation:

Given that

Turner annual salary = $600,000

Counteroffer to received a monthly salary = $40,000 or $480,000 annually

And, $180,000 bonus in 5 years at the age of 65

So the benefit he will be getting would be after accepting the counter offer is

= ($480,000 + $180,000) ÷ 12 months

= $660,000  ÷ 12 months

= $55,000

Dollar Co. sold merchandise to Pound Co. on account, $25,500, terms 2/15, net 45. Pound Co. paid the invoice within the discount
aniked [119]

Answer:

$24,990

Explanation:

2/15 net 45 means that if the customer pays within the period of 15 days, he will get the discount of 2% of invoice amount, otherwise he has to pay the whole amount of invoice within the period of 45 days.

In the given scenario, since the Pound Co. has paid the invoice within the discount period, so therefore, the Pound Co. has availed the discount of 2% and accordingly the sales amount shall be recorded as follows:

Sales amount=Invoice amount*98%

                       =$25,500*98%

                       =$24,990

Newdex has net income of $3,000,000 (INCLUDING the effect of expected out-of-pocket costs) and 1,000,000 shares outstanding. It
kkurt [141]

Answer:

$416,667

Explanation:

Current EPS = $3,000,000 / 1,000,000

Current EPS = $3

Net Proceeds per share = $40 * 90%

Net Proceeds per share = $36  

New Number of Shares = $5,000,000 / $36

New Number of Shares = 138888.88

Total Number of Shares Outstanding after the new issue = 1138888.88 shares

Diluted EPS = $3,000,000 / 1138888.88

Diluted EPS = $2.634

Amount of Dilution in EPS = $3 - $2.634

Amount of Dilution in EPS = $0.3658

Net Income must increase by 1138888.88 * $0.3658 = $416,667. So, Newdex's after-tax income must increase to $416,667 to prevent dilution of earnings per share.

Basics Test - English EXIT PREVIOUS Paul is setting up a marketing/sales event at a community center where he is going to discus
TEA [102]

Answer:

What Paul has done wrong is to place these marketing materials on seats.  He should devised a plan to give out these materials at the registration point where participants would be registered and then they would collect the items.  By placing them on the seats, some of the participants could collect more than one, especially the valuable pen that is worth $3 each.

Explanation:

Marketing materials cost the entity some funds to produce.  They should not be wasted.  In addition, the number of participants with some details like names and contact information should be captured for future marketing efforts.  Allowing participants to have free access to the marketing materials that cost so much without driving any potential customer list is not prudent.
