What % of heights is less than 130 cm

To test the accuracy of the micrometer, the wire thickness was measured 60 times and an empirical standard deviation of 0.05 mm was obtained. Assuming that the distribution of measurement errors is normal, examine at the significance level 0.05 the hypothesis that the micrometer measures with an accuracy of 0.04 mm.
a) The test statistics with the relevant test is:
b) At the significance level of 0.05 WE REJECT / WE DO NOT REJECT H0

1. Determinants of FDI: there are about six key traditional determinants of FDI (firm-level and plant-level scale economies, trade costs, transportation costs, tax differentials, and cost of factors differentials) that are often used in empirical testing of FDI models. List and explain other factors (other than those listed above) that affect the location decisions of FDI/MNCs.

Empirical evidence shows that highly profitable firms tend to have lower debt ratios (debt to equity, debt to total capital, debt to assets, etc.). Briefly explain if this evidence supports or does not support the trade-off theory of capital structure. Also, briefly explain if this evidence supports or does not support the pecking order theory of capital structure.

​When a 1.50 g sample of aluminum metal is burned in an oxygen atmosphere, 2.83 g of aluminum oxide are produced. However, the combustion of 1.50 g ultrafine aluminum in air results in 2.70 g of a product, which is a mixture of 80% aluminum oxide and 20% aluminum nitride (% by mass). Use this information to determine the empirical formulas of aluminum oxide and luminum nitride.

Analyze the yearend adjustments; update the T-accounts and the final trail balance.

Part 2 December Adjustments:

1. Ahern purchased a building for $3,500,000. They purchased it using a mortgage for the full amount. There other properties were fully depreciated. The building had a residual value of $500,000 and an expected life of 75 years. Record the building purchase and this year’s depreciation.

2. The equipment has a residual value of $17,710 and a useful life of 20 years. Record the depreciation for this year.

3. Calculate the interest due for the $600,000 note at % on December 1. Record the year-end interest.

4. The current portion of the new mortgage due is $350,000. Please make the appropriate entries.

5. During the last pay period of the year, a payroll of 5 days was earned with 5 days left in the New Year. 5 workers made $25 an hour for 8 hrs a day. 2 workers worked 4 extra hours on 3 days at time and a half record the entries for December.

6. $100 of unearned revenue was earned by year-end.

7. An insurance policy was purchased on September 1, 2017. For one year in the amount of $6000. Record the entry for December’s expired insurance. It is paid monthly.

8. The ending balance of supplies was $8000.

9. Income tax was calculated at 20%.

Update: I provided an answer of my own (reflecting the things I discovered since I asked the question). But there is still lot to be added. I'd love to hear about other people's opinions on the solutions and relations among them. In particular short, intuitive descriptions of the methods used. Come on, the bounty awaits ;-)

Now, this might look like a question into the history of Ising model but actually it's about physics. In particular I want to learn about all the approaches to Ising model that have in some way or other relation to Onsager's solution.

Also, I am asking three questions at once but they are all very related so I thought it's better to put them under one umbrella. If you think it would be better to split please let me know.

When reading articles and listening to lectures one often encounters so called Onsager's solution. This is obviously very famous, a first case of a complete solution of a microscopic system that exhibits phase transition. So it is pretty surprising that each time I hear about it, the derivation is (at least ostensibly) completely different.

To be more precise and give some examples:

The most common approach seems to be through computation of eigenvalues of some transfer matrix.
There are few approaches through Peierl's contour model. This can then be reformulated in terms of a model of cycles on edges and then one can either proceed by cluster expansion or again by some matrix calculations.

The solutions differ in what type of matrix they use and also whether or not they employ Fourier transform.

Now, my questions (or rather requests) are:

Try to give another example of an approach that might be called Onsager's solution (you can also include variations of the ones I already mentioned).
Are all of these approaches really that different? Argue why or why not some (or better yet, all) of them could happen to be equivalent.
What approach did Onsager actually take in his original paper. In other words, which of the numerous Onsager's solutions is actually the Onsager's solution.

For 3.: I looked at the paper for a bit and I am a little perplexed. On the one hand it looks like it might be related to transfer matrix but on the other hand it talks about quaternion algebras. Now that might be just a quirk of Onsager's approach to 4x4 matrices that pop basically in every other solution but I'll need some time to understand it; so any help is appreciated.

Web Application Development Course - C#

Update the ASP.NET web application code by adding below functionality:

• Create a new web form called Welcome.aspx and add labels to show name, company, email, and membership.

• Create a new business layer class called Customer to hold the entered user details

• When the user clicks on Sign Up button and if all the validations on the page pass

o Store the details entered on page in the Customer object.

o Save the Customer object in Session State.

o Navigate to Welcome.aspx, read the Customer object from Session State and show the name, company, email and membership on this page using respective labels.
