e Elixer Drug Company produces a drug from two ingredients. Each ingredient contains the same three antibiotics, in different proportions. One gram of ingredient 1 contributes 3 units, and 1 gram of ingredient 2 contributes 1 unit of antibiotic 1; the drug requires 6 units. At least 4 units of antibiotic 2 are required, and the ingredients contribute 1 unit each per gram. At least 12 units of antibiotic 3 are required; a gram of ingredient 1 contributes 2 units, and a gram of ingredient 2 contributes 6 units. The cost for a gram of ingredient 1 is $80, and the cost for a gram of ingredient 2 is $50. The company wants to formulate a linear programming model to determine the number of grams of each ingredient that must go into the drug to meet the antibiotic requirements at the minimum cost.

1. Formulate a linear programming model for this problem.

2. make a table

3. Find critical points & evaluate the critical points

4. find the regions

5. Solve this model by using graphical analysis

Ace Ltd has in place a defined benefit pension plan for all its management employees and service gratuity scheme for all contract employees.

e) Explain meaning of control environment and state the implication of weak control environment to the overall approach of the audit work.

In a three-digit lottery, each of the three digits is supposed to have the same probability of occurrence (counting initial blanks as zeros, e.g., 32 is treated as 032). The table shows the frequency of occurrence of each digit for 90 consecutive daily three-digit drawings.
    

(a) Calculate the chi-square test statistic, degrees of freedom, and the p-value. (Perform a uniform goodness-of-fit test. Round your test statistic value to 2 decimal places and the p-value to 4 decimal places.)

(b) Choose the correct answer by drawing a bar chart for the above data.

• The graph will reveal that 7 occurs least frequently.

• The graph will reveal that 8 occurs least frequently.

List of Accounts

1. Myristoyl-CoA is a saturated fatty acid with 14 carbons attached to coenzyme A. How many molecules of ATP would be generated from the complete oxidation of a single molecule of myristoyl-CoA? Important notes: Recall that the investment of 2 ATP is required to generate Myristoyl-CoA from myristate. Do not include these 2 ATP in your calculations of ATP yield. Assume that each molecule of NADH corresponds to 2.5 ATP synthesized, and each molecule of FADH₂ leads to 1.5 ATP synthesized.

a. Glucokinase has a lower affinity for glucose than hexokinase.

b. Glucokinase has a higher affinity for glucose than hexokinase.

c. Glucokinase is allosterically activated by glucose, hexokinase is not.

d. Glucokinase is allosterically inhibited by glucose, hexokinase is not.

e. Hexokinase is allosterically inhibited by glucose 6-phosphate, glucokinase is not.

Roger and Zoë spend their vacation time at a nice cottage that they own in the countryside. Farmer Torti lives next door and normally lets his twelve sheep graze in his field. The sheep eat so quickly that it causes them to burp loudly, a very disruptive sound for Roger and Zoë vacationing next door. Torti is willing to remove sheep from the field when Roger and Zoë are there, but his marginal cost of doing so is $1 for the first sheep he removes, $2 for the second sheep, $3 for the third, etc. Roger and Zoë derive a (combined) marginal benefit of $12 for the first sheep Torti removes, $11 for the second sheep he removes, $10 for the third sheep he removes, etc.

a. Calculate the efficient number of sheep in the field if Roger and Zoë stay at the cottage.

b. Calculate the maximum amount Roger and Zoë would be willing to pay Torti to reduce his sheep to the efficient number.

c. Calculate the minimum amount Torti would be willing to accept to reduce his sheep to the efficient number

d. Calculate the range of prices per sheep that Roger and Zoë could pay Torti to achieve the efficient number.

A sound barrier built between the two properties could block 50 percent of the burping sound.

e. Calculate the efficient number of sheep in the field if there were a sound barrier and if Roger and Zoë stay at the cottage.

f. Calculate the total benefit to Roger and Zoë if the sound barrier were there and the corresponding efficient number of sheep were in the field.

g. Calculate the total cost to Torti if the sound barrier were there and the corresponding efficient number of sheep were in the field.

h. Calculate the maximum amount Roger and Zoë would be willing to contribute to the construction of the sound barrier.

i. Calculate the maximum amount Torti would be willing to contribute to the construction of the sound barrier.
