Explanation:

no more than 5 percent of the tires will have to be replaced...

then z = -1.6449

x = -1.6449*2050 + 47900 = 44,528

Answer:

The manufacturer should announce a guaranteed mileage of 44528 miles

Explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean \mu and standard deviation \sigma, the zscore of a measure X is given by:

Z = \frac{X - \mu}{\sigma}

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this problem, we have that:

\mu = 47900, \sigma = 2050

What guaranteed mileage should the manufacturer announce

Only until the 5th percentile will have to be replaced, which is the value of X when Z has a pvalue of 0.05. So it is X when Z = -1.645.

Z = \frac{X - \mu}{\sigma}

-1.645 = \frac{X - 47900}{2050}

X - 47900 = -1.645*2050

X = 44528

The manufacturer should announce a guaranteed mileage of 44528 miles

Zigmanuir [339]

Answer:

A) Journal entries:

Apr 30 - Debit Cash Account with $624,000

Credit Note Payable (Commerce Bank) with $624,000

Being 12-month, 7% promissory note

June 6 - Debit Purchases Account with $77,000

Credit Accounts Payable with $77,000

Being purchase of goods on account

July 15 - Debit Accounts Payable with $77,000

Credit Cash Account with $77,000

Being payment for goods bought on account

Aug 31 - Debit Cash Account with $25,000

Credit Deferred Revenue with $25,000

Being Security service income received in advance

Dec 31 - Debit Salaries & Wages Account with $42,000

Credit Salaries & Wages Payable Account with $42,000

Being salaries & wages due but not paid

Dec 31 Debit Interest Expense Account with $29,120

Credit Interest Payable Account with $29,120

Being 7% interest on 12-months Note from Commerce Bank accrued for 8 months.

Dec 31 - Debit Deferred Revenue with $16,667

Credit Security Service Income Account with $16,667

Being security service income due for 4 months.

B) Liabilities Arising from above items to be reported in Balance Sheet at December 31:

1) Notes Payable - $624,000

2) Deferred Revenue - $8,333 ($25,000 - $16,667)

3) Wages Payable - $42,000

4) Interest Payable - $29,120

Explanation:

a) The 12-month 7% Note received from Commerce Bank on April 30 increases the Cash and the Notes Payable by $624,000.  This balance represents a liability in the balance sheet.

b) The purchase of goods on June 6 increases Inventory and Accounts Payable by $77,000.  And the payment on July 15 cancels out the Payable while reducing Cash balance.  There is no liability arising from these transactions on the balance sheet date.

c) When payment for security service is received six months in advance, there is a deferred revenue to be recognized.  Part of this (for 4 months) is later recognized in the accounts because the service had been rendered partly.  This is equal to $25,000 x 4/6 = $16,667.  The balance of $8,333 is recognized as a liability.

d) Salaries and Wages determined to be $42,000 were not paid as at December 31.  This gives rise to a liability (Wages Payable).  However, the unpaid $42,000 is accrued and recognized as an expense in the income statement.

e) Interest Expense Account is calculated at 7% on the 12-month Promissory Note of $624,000 for 8 months.  This gives $29,120 (624,000 x 7% x 8/12).

Mrs. Jones always wanted a white picket fence in front of her house. Mr. Jones, her husband, wants a fence around the entire hou
Kazeer [188]

Answer:

The dimensions for the entire area will give the cheapest cost for the entire fence are 40 feet in front, 100 feet on each side, and 40 feet on bottom.

Explanation:

Since Mrs. Jones always wanted a white picket fence in front of her house, and Mr. Jones, her husband, wants a fence around the entire house including a decently-sized lawn in the front and a garden in the back, and the fence border should look like a rectangle, and I have calculated that he would need to fence off an area of ​​4,000 square feet in order to fit all these things, and he wants to appease his wife and at least build the white picket fence in front of the house, and he plans to build the rest of the fence with chain link, a cheaper material, given that a white picket fence costs $ 7 per foot and a chain link fence costs $ 4 per foot, to determine what dimensions for the entire area will give the cheapest cost for the entire fence, the following calculation should be performed:

Area of ​​a rectangle = base times height = Z x Y = 4,000

80 x 50 = 4,000

40 x 100 = 4,000

20 x 200 = 4,000

20 x 7 x 2 + 200 x 4 x 2 = X = 280 + 1600 = 1880

40 x 7 x 2 + 100 x 4 x 2 = X = 560 + 800 = 1360

80 x 7 x 2 + 50 x 4 x 2 = X = 1120 + 400 = 1520

Therefore, the dimensions for the entire area will give the cheapest cost for the entire fence are 40 feet in front, 100 feet on each side, and 40 feet on bottom.

In a manufacturing company as many as 100 labourers are working in the production department.
snow_tiger [21]

Answer:

On one hand, the principle of management which is being ignored in this case is that of Unity of Command.

Explanation:

The principle of Unity of Command stipulates all staff or employee, for sakes of clarity and avoidance of confusion, an abiguity, should take instructions from only one boss or line manager.

On the other hand, the principle of management that is being followed in the above case is that of Taylors Functional Foremanship.

The practice of this technique requires that planning and execution be seperated according to areas of specialisation. Specialisation is the primary logic or argument in the Taylors Functional Foremanship principle. Taylors advocates that each foreman needs to be highly proficient, possess special know-how and be capable of directing the staff with high exuberance and tact.

Cheers!
