According to the Bureau of Labor Statistics, in calendar year 2000, the average duration of unemployment was 12.7 weeks, with a

standard deviation of 0.3 weeks. Assuming that distribution is approximately normal, what is the probability that a randomly selected individual who was unemployed in 2000 would have been unemployed between 12 and 13 weeks?

Answer:

0.8314

Explanation:

First, we are given the following

Unemployment during on Average = U= 12.7 weeks

Standard deviation= SD = 0.3 Weeks

Therefore, P (12  Greater than x  Greater than 13)

= P (12-12.7 /0.3 Greater than X -U/SD Greter than 13-12.7/0.3)

= P (-0.7/0.3 Greater than Z Greater than 0.3/0.3)

= P (-2.33 Greater than  Z  Greater than   1)

= P (Z Greater than 1)  - P (Z Greaer than -2.33)

At this Point we make use of he Z table to find out the figure

= 0.8413 - 0.0099

= 0.8314

The cob Douglas production function is given by Q(K,L)=AK^1.4*L^1.6
Alexeev081 [22]

Part a) The Cob Douglas production function is given as:

Q(K,L)=AK^{1.4} L^ {1.6 } .

To show that this function is homogeneous with degree 3, we introduce be a parameter, t.

Q(tK,tL)=A(tK)^{1.4} (tL)^ {1.6 } .

Using properties of exponents, we on tinder:

Q(tK,tL)=At^{1.4}K^{1.4} t^ {1.6 }L^ {1.6 } .

This implies that:

Q(tK,tL)=t^{1.4} \times t^ {1.6 }(AK^{1.4} L^ {1.6 } )

Q(tK,tL)=t^{1.4 + 1.6}(AK^{1.4} L^ {1.6 } )

Simplify the exponent of t to get;

Q(tK,tL)=t^{3}(AK^{1.4} L^ {1.6 } )

Hence the function is homogeneous with degree, 3

Part b) To verify Euler's Theorem, we must show that:

K\frac{\partial Q}{\partial \: K}+L\frac{\partial Q}{\partial \: L}=3AK^{1.4}L^{1.6}

Verifying from the left:

K\frac{\partial Q}{\partial \: K}+L\frac{\partial Q}{\partial \: L} =K(1.4AK^{0.4} L^{1.6}) + L(1.6AK^{1.4} L^{0.6})

K\frac{\partial Q}{\partial \: K}+L\frac{\partial Q}{\partial \: L} =1.4(AK^{1.4} L^{1.6}) + 1.6(AK^{1.4} L^{1.6})

K\frac{\partial Q}{\partial \: K}+L\frac{\partial Q}{\partial \: L} =(1.4 +  1.6)(AK^{1.4} L^{1.6})

K\frac{\partial Q}{\partial \: K}+L\frac{\partial Q}{\partial \: L} =3(AK^{1.4} L^{1.6})

zepelin [54]

The notion that developing countries can catch up or converge with developed countries is one of the key insights of a branch of economics called <u>development</u> economics.

Economics is the observation of scarcity and its implications for the use of assets, manufacturing of products and services, growth of manufacturing and welfare over time, and an outstanding form of other complicated issues of crucial problems to society.

Economics is the social science that researches the manufacturing, distribution, and intake of products and services. Economics specializes in the behavior and interactions of financial agents and how economies work.

Economics, at its very heart, is the study of people. It seeks to give an explanation for what drives human behavior, decisions, and reactions when confronted with difficulties or successes. Economics is an area that combines politics, sociology, psychology, and records.

At December 31, Amy Jo's Appliances had account balances in Accounts Receivable of $302,000 and in Allowance for Uncollectible A
Lunna [17]

Answer:

$870

Explanation:

When a company makes sales on account, debit accounts receivable and credit sales. Based on assessment, some or all of the receivables may be uncollectible.  

To account for this, debit bad debit expense and credit allowance for doubtful debt. Should the debt become uncollectible (i.e go bad), debit allowance for doubtful debt and credit accounts receivable.

Allowance for uncollectible accounts at 5%

= 5% * $302,000

= $1,510

Since the Allowance for Uncollectible Accounts was $640 (credit) before any adjustments, the bad debt expense for the year

= $1,510 - $640

= $870
