Here are two sets of BNF grammars specifying the syntax of a language:

<exp> ::= <term> | <term> + <exp> | <term> - <exp>

<term> ::= <op> | <op> * <term>

<op> ::= <int> | <id> | (<exp>)

*********************************************

<exp> ::= <term> | <term> + <exp> | <term> - <exp> | (<exp>)

<term> ::= <op> | <op> * <term>

<op> ::= <int> | <id>

<int> will lead to non-terminals of a digit or digit sequence '123' etc.

<id> will lead to non-terminals of letters 'ABC' etc.

Do these grammars have the same set of possible outputs?

Are these grammars syntactically different? Are they semantically different? Explain

1. Determine if each of the following recursive definition is a valid recursive definition of a function f from a set of non-negative integers. If f is well defined, find a formula for f(n) where n is non-negative and prove that your formula is valid.

   1. f(0) = 1, f(n) = -f(n-1) + 1 for n ≥ 1

   2. f(0) = 0, f(1) = 1, f(n) = 2f(n-1) +1 for n ≥ 1

   3. f(0) =0, f(n) = 2f(n-1) + 2 for n ≥ 1

Mr Howe a junior partner of CPA fir, Dewey, CHeatem and Howe (DCH) is very excited about the opprtunities created by fair value relvaluation of non current assets. hr believes that there is an enormous opportunities for large firms to increase their book profits via the gains from such revaluations.

Required:

Mr Tu Dewie has asked you to review the AASB rules on the fair market revaluation of non current assets and to assess what profit enhancing opportunities may arise because of those rules.

I'm working on a free store pop up shop.And the items that we would be using are schools supplies and donated cloths from students. So please i want the answers to this questions. please i need this asnwered asap

Questions

•How can handling of merchandise from different suppliers be coordinated?

•How much inventory should be on the sales floor versus in a warehouse or storeroom?

•How often should inventory be moved from non-selling to selling areas of a store?

•What inventory functions can be done during non-store hours?

a) Show that when relative PPP holds, r(AU) = r(EU). Note: r denotes real interest rate.

b) Assume that worker productivity is expected to increase in the European tradables sector in the future. Assume further that worker productivity is expected to stagnate in European non-tradables sector as well as in all Australian sectors (tradables and non-tradables) in the future. What implication does this have on the difference between real interest rates in Australia and Europe?

c) Do real interest differences imply unnoticed profit opportunities for international investors? Explain.

A chocolate e-commerce website selling its goods and delivering it to its customers . Ofcourse infront of many e-commerce sites there are many threats and many secure security concerns should take place .

As for the case of the chocolate e-commerce site :

1) What kind of threats can the site faces? ( atleast 4 threats)

2) Which technical and non technical precautions can the site developers do to respond to these threats ? ( 3 precautions each ie, technical and non-technical)

Make sure that the techniques used with the chocolate target market are compatible

4. Carolina issued a 25-year semi-annual non-callable bond five years ago. Bond has a $1,000 face value, coupon rate of 8% and it currently sells for $925. Carolina needs to issue 20-year semi-annual bond. New bond will be non-callable and is expected to get the same credit rating as outstanding bond issue. If Carolina wants to issue and sell new bond at par, find approximate coupon rate that needs to be assigned to the bond. (Hint: similar bonds/notes should be providing approximately same returns).

Answer the following questions using the standard leisure-work choice model

a)Draw a budget constraint for a worker has a job which pays a wage of $10.00 per hour. Draw an indifference map for typical worker. Assume that the worker is able to choose any number of hours of work and this worker’s optimal position is to work 8 hours a day. Show this point on your graph.

b)Suppose the worker now receives $60 per day non-labor income. On your graph (from part a) draw another budget constraint to illustrate this non-labor income. Show the new optimal position for the worker. Briefly, explain your new position and any change in the number of hours worked per day.

c)Using the information above, re-draw an indifference map for a worker who decides not to work after receiving the $60 per day non-labor income. Show the optimal position on your graph. Briefly explain why this individual is or is not rational by choosing not to work.

Your Rating: 1 2 3 4 5 "Consolidated Financial Statements – Intra-Entity Asset Transactions" Please respond to the following: Per the textbook, no official FASB guidance exists on the assignment of income effects on non-controlling interest in the consolidation process, when either the parent transfers a depreciable asset to the subsidiary or vice versa. Suggest one (1) method of accounting for the income effects on the non-controlling interest that you consider most appropriate. Provide a rationale for your response. Assume that company P (parent) uses the equity method to account for its investment in company S (subsidiary). Company P purchases inventory items from company S. According to FASB’s guidance, the accountant must remove the inter-company profit from Company S’s net income. Determine if the process permanently eliminates the profit from the non-controlling interest or merely shifts the profit from one period to the next. Provide support for your rationale.

A student researcher compares the heights of American students and non-American students from the student body of a certain college in order to estimate the difference in their mean heights. A random sample of 17 American students had a mean height of 70 inches with a standard deviation of 1.73 inches. A random sample of 12 non-American students had a mean height of 66 inches with a standard deviation of 2.23 inches. Determine the 90% confidence interval for the true mean difference between the mean height of the American students and the mean height of the non-American students. Assume that the population variances are equal and that the two populations are normally distributed.

Step 1 of 3: Find the point estimate that should be used in constructing the confidence interval.

Step 2 of 3: Find the margin of error to be used in constructing the confidence interval. Round your answer to six decimal places.

Step 3 of 3: Construct the 90% confidence interval. Round your answers to two decimal places.
