Given:
μ = 9.9 hours, population mean
σ = 4.54 hours, population standard deviation

For the random variable x = 3 hours, the z-score is
z = (3 - 9.92)/4.54 = -1.5242

From standard tables, obtain
P(x ≤ 3) = 0.064 = 6.4%


Answer: 6.4% on both tails of the normal distribution

sweet [91]

Answer:

The correct answer is C)

Explanation:

A pledge in this context is a vow or a promise to make a donation or give something at a future date. It may be vocalized or communicated in writing.  

The Financial Accounting Standards Board (FASB), sets out the criteria for recognizing a pledge or a promise as follows:

  1. Relevance— If the promise is important enough to make a difference in the users  decisions,  then it ought to be recognized
  2. Definitions—If the item satisfies the definition of a component of a financial statement, then it ought to be recognized;
  3. Dependability— When the pledge is based on a fact that can be recorded, verifiable, and neutral, then it can be recognized
  4. Measurability— if it allows for measurability, then it should be recognized

It is clearly stated that where the certainty or reliability of a promise or a vow is difficult that measure, it is better to decline from recognizing such a pledge.

                 

Cheers!

Ierofanga [76]

Answer:

Option (C) is correct.

Explanation:

Selling price of a basketball = $170

A potential buyer contacts you and offers to pay you$170 Canadian dollars.

Exchange rate between the U.S and Canada is as follows:

$1 U.S = $1.25 Canadian

So,

Worth of $170 U.S in terms of Canadian dollar is as follows:

= $1.25 × $170

= $212.5 Canadian dollars

If you take this deal, you will have returned Steve to his homeland and Earned less than if you accept $170 U.S.

Because, the worth of $170 U.S dollars is $212.5 Canadian dollars. Hence, there is a loss of $42.5 Canadian dollars if he will accept the deal.

So, it is better for him to accept $170 U.S dollars.
