Koontz Company manufactures a number of products. The standards relating to one of these products are shown below, along with actual cost data for May. Standard Cost per Unit Actual Cost per Unit Direct materials: Standard: 1.80 feet at $1.00 per foot $ 1.80 Actual: 1.75 feet at $1.40 per foot $ 2.45 Direct labor: Standard: 0.90 hours at $15.00 per hour 13.50 Actual: 0.95 hours at $14.60 per hour 13.87 Variable overhead: Standard: 0.90 hours at $6.00 per hour 5.40 Actual: 0.95 hours at $5.60 per hour 5.32 Total cost per unit $ 20.70 $ 21.64 Excess of actual cost over standard cost per unit $ 0.94 The production superintendent was pleased when he saw this report and commented: “This $0.94 excess cost is well within the 5 percent limit management has set for acceptable variances. It's obvious that there's not much to worry about with this product." Actual production for the month was 10,000 units. Variable overhead cost is assigned to products on the basis of direct labor-hours. There were no beginning or ending inventories of materials. Required: 1. Compute the following variances for May: a. Materials price and quantity variances. b. Labor rate and efficiency variances. c. Variable overhead rate and efficiency variances. 2. How much of the $0.94 excess unit cost is traceable to each of the variances computed in (1) above. 3. How much of the $0.94 excess unit cost is traceable to apparent inefficient use of labor time?

Joe's retirement scheme at work pays $500 at the end of each month. Joe puts his money in an account which earns nominal 12% converted monthly, the interest is reinvested at a nominal 4% converted monthly. Carol's account also pays $500 at end of each month, but earns nominal 12% convertible monthly (principal and interest both earn 12%). After 20 years, they retire. Carol has $184,465.8246 more than Joe at this time.

Same scenario above: How long until Carol's account exceeds Joe's by $1,000,000?

PART 2:

The researchers hypothesized that mice consuming more saturated fats will have a higher probability of becoming obese and developing symptoms of diabetes. To test for dietary effects on the development of metabolic disease, the researchers collected additional data from the two cohorts of mice. They measured the fasting blood glucose levels and they performed an insulin tolerance test (effect of a dose of insulin on blood glucose level). Data are reported as means (±SEM).

• Using a t-test, determine whether the difference in the fasting blood glucose levels for the lard-fed and the fish oil-fed mice is significant.

• Plot the glucose over time data.

• Did the two groups of mice differ in their response to the same dose of insulin? At which time points?

• What conclusions can you make about the effect of the type of dietary fat on carbohydrate metabolism?

PART 3:

To determine whether the difference in the microbiota is responsible for the difference in the weight gain or just a consequence of the different diet, the researchers raised mice for 11 weeks on either a lard or fish-oil diet. Then they took two new groups of mice and treated them with antibiotic to kill their gut microbiota. These mice then received transplants of the microbiota from the mice that had been fed either lard or fish oil for 11 weeks. All of the “transplanted” mice were maintained on a lard diet for 3 weeks to see if there was a difference in their weight gain.

• Was there a significant difference in the weight gain in these two groups of mice?

• What conclusion can you make about the effect of the microbiota composition versus the diet on weight gain?

• What additional information would you want to have to support your conclusion?

Going Lean at Starbucks

It started off as a day basically like any other. You went into the Starbucks that you manage, helped the employees open the store, and thought about making a dent in the mountain of paperwork left over from the previous week. But then, you got an unexpected visit from a team at the corporate office. They started talking about the need to lower labor costs, improve efficiency, and increase productivity. When you asked them how they planned on doing all that, their response was “lean production.”

They informed you that lean production is a management philosophy derived from Toyota that is focused on reducing waste. Whether it’s wasted motion, wasted time, or wasted parts, the goal of lean production is to eliminate waste so that all the members of an organization can do their work efficiently. The executives then show you all the “waste” that’s in your stores right now—baristas bending over to scoop coffee from a counter below, others waiting for coffee to fully drain before starting a new pot, one worker carrying trays of pastries from storage to the display case, another spending ten seconds per drink to read the milk label. They even show you a map showing the winding trail that a barista takes in making a single drink. It looks like a big pile of spaghetti, you think to yourself.

With lean production, the executives explain, you can reduce the amount of motion that employees spend making drinks, and the amount of time they spend reaching for stuff, reading labels, or moving from here to there. This will make your store more efficient and productive, so that the same number of employees can serve more customers.

You’re intrigued by all of this, as nothing would please your supervisors more than increased revenue and lower costs. But you’re also worried about how your employees will react. Many of them came to work at Starbucks because it wasn’t like other fast-food chains that only focus on speed, speed, and speed. How will they feel once you tell them that they’ll have to change the way they work to become faster? What if they feel like you just want them to be coffee-making robots, leaving them no time to interact with customers or experiment with new drinks? Consider these issues with the questions below.

1. How would an increase in efficiency and production benefit your employees?
2. How would you address employees’ concerns that they are being transformed into coffee-making robots?

The Problem with Cups

Starbucks has always strived to take leadership in environmental issues, whether it was by encouraging customers to compost used coffee grounds or offering free coffee drinks to customers who brought in their own reusable mugs. But the company faces a major problem that has few solutions—cups. Across all of its stores, Starbucks uses more than 3 billion paper cups every year, most of which end up in the trash. Though the company would love to recycle these cups, it can’t, since most processors don’t have a process for recycling paper cups that are lined with plastic, as the Starbucks cups are. The plastic lining also prevents the cups from being composted.

3. How can Starbucks maintain its commitment to reducing waste as it keeps sending paper cups to landfills?
4.   What steps do you think Starbucks could take to reduce the number of paper cups it uses?
5.   Describe the strategies managers can use for waste prevention and reduction.

Lubricants, Inc., produces a special kind of grease that is widely used by race car drivers. The grease is produced in two processing departments—Refining and Blending. Raw materials are introduced at various points in the Refining Department.

The following incomplete Work in Process account is available for the Refining Department for March:

The March 1 work in process inventory in the Refining Department consists of the following elements: materials, $7,100; direct labor, $3,300; and overhead, $21,300.

Costs incurred during March in the Blending Department were: materials used, $46,000; direct labor, $17,300; and overhead cost applied to production, $98,000.

Required:

1. Prepare journal entries to record the costs incurred in both the Refining Department and Blending Department during March. Key your entries to the items (a) through (g) below.

1. Raw materials used in production.
2. Direct labor costs incurred.
3. Manufacturing overhead costs incurred for the entire factory, $696,000. (Credit Accounts Payable.)
4. Manufacturing overhead was applied to production using a predetermined overhead rate.
5. Units that were complete with respect to processing in the Refining Department were transferred to the Blending Department, $672,000.
6. Units that were complete with respect to processing in the Blending Department were transferred to Finished Goods, $750,000.
7. Completed units were sold on account, $1,340,000. The Cost of Goods Sold was $640,000.

2. Post the journal entries from (1) above to T-accounts. The following account balances existed at the beginning of March. (The beginning balance in the Refining Department’s Work in Process is given in the T-account shown above.)

This question need to be solved using java coading :-

I. Input

   All input data are from a file "in.dat". The file contains a
sequence of infix form expressions, one per line. The character '$' 
is an end mark. For example, the following file has four infix form 
expressions:

   1 + 2 * 3 ^ ! ( 4 == 5 ) $
   3 * ( 6 - 4 * 5 + 1) + 2 ^ 2 ^ 3 $
   77 > ( 2 - 1 ) + 80 / 4 $
   ! ( 2 + 3 * 4 >= 10 % 6 ) && 20 != 30 || 45 / 5 == 3 * 3 $

Each expression is a sequence of tokens (i.e., constant integers,
operators, and end mark) separated by spaces. There is no variable.


II. Output

   Output data and related information are sent to the screen.
Your program should do the following for each expression:

   (1) printing the expression before it is manipulated;
   (2) showing the converted postfix form expression;
   (3) showing the expression tree;
   (4) printing the fully parenthesized infix form expression;
   (5) reporting the value of the expression.


III. Operators

   The following operators are considered. They are listed in the
decreasing order of precedence.

   Token            Operator            Associativity

    !               logical not         right-to-left
    ^               exponentiation      right-to-left
    *  /  %         multiplicative      left-to-right
    +  -            additive            left-to-right
    <  <=  >  >=    relational          left-to-right
    ==  !=          equality            left-to-right
    &&              logical and         left-to-right
    ||              logical or          left-to-right


IV. Other Requirements

   Since a large amount of information are to be displayed on the
screen, it is mandatory for your program to provide users a prompting
message such as

          Press <Enter> to continue ...

after each expression is processed, so that users have the chance to
check the output of your program carefully.


V. Algorithm: Infix_to_postfix conversion

  Input:  An infix form expression E = t1 t2 t3 ... $,
          which is a sequence of tokens.
  Output: The postfix form expression of E.

  Algorithm: 
  {
    do {
      get the next token t;
      case (t) {
         operand: place t onto the output;
                  break;
        operator: while (stack s is not empty
                    && stacktop(s) is not a left parenthesis)
                    && precedence(stacktop(s)) >= precedence(t)
                       // assuming left-to-right associativity, 
                       // not for the exponentiation operator ^, 
                       // which has right-to-left associativity 
                  {
                        pop(x,s);
                        place x onto the output;
                  }
                  push(t,s);
                  break;
               (: push(t,s);
                  break;
               ): while (stacktop(s) is not a left parenthesis) {
                      pop(x,s);
                      place x onto the output;
                  }
                  pop(x,s);
                  break;
        end mark: while (stack s is not empty) {
                      pop(x,s);
                      place x onto the output;
                  }
                  place the end mark onto the output;
                  break;
      }
    } while (t is not the end mark);
  }

Develop a C++ class called PrimeNumberGenerator. An object of this class will generate successive prime numbers on request. Think of the object as being similar to the digital tasbeeh counter. It has a reset button which makes the counter return to 0. There is also a button to get the next prime number. On the tasbeeh, pressing this button increments the current value of the counter. In your object, pressing this button would generate the next prime number for display. You’ll implement the reset button as a member function reset() and the other button as a function getNextPrime(). When an object is first created and the getNextPrime() function is called, it will return the first prime number, i.e., 2. Upon subsequent calls to the getNextPrime() function, the subsequent prime numbers will be returned. Define any others functions such as constructor and attributes that you need. According to Wikipedia: “a prime number is a natural number greater than 1, that has no positive divisors other than 1 and itself.”
