Answer:

Correct answer is C i.e 25%

Explanation:

Arrival rate = λ = 60 / hour

Service Rate = μ = (60 * 60) / 45 = 80 / hour

Probability of no customers in the system = Po = 1 - λ/μ = 1 - 60/80 = 0.25 or 25%

NISA [10]

The three factors used to determine a company’s credit rating are its current ratio, its debt-to-equity ratio, and its interest coverage ratio.

<u>Explanation:</u>

  • A credit rating comes in the list of the company’s annual performance targets. It helps to decide the company’s current year progress.  
  • A company’s debt-to-equity ratio is used to know the debt of a company as compared to the total equity. If this ratio is high, the company is taking on much debt.  
  • The current ratio marks a way to compute the liquidity of the company. It shows how well a firm is placed to meet the short term obligations. Broadly, a 2-1 ratio is considered a good ratio.
  • The interest coverage ratio tells how well the company may pay its future loan payments. If the ratio is higher than 3-to-1, it suggests that the company is in a good position to make future payments.

ivolga24 [154]

Answer:

Cost of goods Sold = $384,000

Gross Profit = $259,000

Explanation:

Cost of goods sold = Opening Inventory + Net Purchase - Closing Inventory

Opening Inventory = $58,100  Closing Inventory = $92,600

Net Purchases = Purchase - Purchase Return - Discounts + Freight in

Freight in forms part of cost of purchase because without this expense inventory cannot be bought in.

Net Purchases = $420,800 - $11,900 - $8,100 + $17,700 = $418,500

Cost of goods Sold = $58,100 + $418,500 - $92,600 = $384,000

Gross Profit = Sales - Cost of Goods Sold

= $643,000 - $384,000 = $259,000.
