A trapezoid-shaped potato with base lengths of 1.5 cm and 2.0 cm respectively and a height/thickness of 0.5 cm was dried at a temperature of 70 ^oC in a convective oven for 24 h, if the surface temperature of the potato remained at 65 ^oC throughout the drying operation, describe the different changes that occurs during the constant and falling rate periods. If the convective heat transfer coefficient of stem/water is given as 850 W/m^2oC, calculate the amount of heat transferred into the potato

1.A particular bank requires a credit score of 640 to get approved for a loan. After taking a sample of 107 customers, the bank finds the 95% confidence interval for the mean credit score is:

662 < μ < 739

Can we be reasonably sure that a majority of people will have a credit score over 640 and be able to get the loan?

• Yes
• No

Why or why not?

2. Create two class, a student class, and a course class, take advantage of the codes provided in the class slides and sample codes. python

3. Create a student object for every student in the UD.txt (you can use a loop for this)

4. Create 6 course objects:

5. After the student user login to their account as we have done in lab 2. Display the following:

When students choose option A, should display the following, where # is the actual number of students enrolled in the class.

Let the students add or drop a classes as they wish. When they choose E, exit the program.

6. For option D, show the courses in the student’s course list.

7. The hard part. Since your program will end when user chose option E. You need to keep track the classes been added and dropped by each students, and who are actually in the classes. Therefore, based on your experiences in lab 3 and 4, create a SI.txt (student info) to store the courses in each student’s course list. Create CI.txt (course info) to store all the students enrolled in each course. This will be executed in the background every time when the user chose option E: Exit. When you run your program, and create your course objects, this information needs to be read into each student and course object. When a student log into his or her account, the student should be able to see what courses is in the course list by chose option D. The number of students in each course also need to be displayed in Option A.

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, $7,200; direct labor, $3,800; and overhead, $20,800.

Costs incurred during March in the Blending Department were: materials used, $45,000; direct labor, $16,400; and overhead cost applied to production, $104,000.

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, $666,000. (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, $692,000.
6. Units that were complete with respect to processing in the Blending Department were transferred to Finished Goods, $780,000.
7. Completed units were sold on account, $1,380,000. The Cost of Goods Sold was $630,000.

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.)

   2. Determine P (Y ≥ 5).

   3. DetermineP(1≤Y ≤4).

   4. What is the probability that none of the 25 boards are defective?
