Write a program that prompts the user to enter the number of students and each student’s name and score, and finally displays the student with the highest score and the student with the second-highest score. Use the next() method in the Scanner class to read a name rather using the nextLine() method.

Define a Python function which finds the all of the odd numbers and the product of the odd numbers. (Use for loop and if conditions for this problem. Do not use existing codes. Use your own codes).(You need to use append function to obtain a list of odd numbers)

]write two main programs: one will add exception handling to a geometric object, and the other will create a Template function to find the max of three “entities” (either ints, floats, doubles, chars, and strings)

A trapezoid is a quadrilateral in which two opposite sides are parallel. (note: all squares, rectangles, and parallelograms are trapezoids)

Note 1: the length of Base 1 is always greater than or equal to Base 2

Note 2: To form a valid trapezoid, if must satisfy the side/length rule, namely, the sum of the lengths of Leg1,Leg2 , and Base 2 must be greater than the length of Base 1

Note 3:If a default trapezoid is created, set all the sides equal to 1 (i.e., a square, or rhombus)

The following is the UMs for a trapezoid:

For the driver program:

Note 1: If the user creates a trapezoid that violates the side/length rule (including 0 or negative side lengths), throw an exception

Note 2: If the user sets one of the sides that violates the side/length rule, do not change the side, and throw an exception

The air in a building is to be maintained at 25°C dry bulb temperature and 60% relative humidity when the outside conditions are 35°C, 50% saturation with a barometric pressure of 101.3 kPa. The total heat gains to the room are 15 kW sensible heat and 3 kW latent heat. There is no recirculation and the fresh air passes over a cooling coil to dehumidify it, and then a heater before entering the room. The cooling coil by pass factor is 0.18; the volume flow of fresh air is 5m³/s. Calculate (a) the temperature of the air leaving the cooling coil; (b) the refrigeration load for the coil in kW; (c) the heat supplied in the heater in kW.

The just-in-time (JIT) movement has long argued that firms should:

• Maximize their process flexibility so that ordering costs are minimal.
• Stabilize demand levels.
• Shrink lead times as much as possible.
• Assign much higher holding costs to inventory than has traditionally been the case.

Using the economic order quantity (EOQ) and reorder point (ROP) formulas, explain how such efforts would be consistent with JIT's push for lower inventory levels

Using C language:

1. Write a program that asks the user for the size of an array, then reads a number of integer values (from user input) into the array. Write a function to print out the array and call it to print the array out after all values are read in. Write a function to implement Insertion Sort and run it on the data array to sort the array. Write another function to implement Selection Sort and run it on the data array.  Print out the array before and after each sort. NOTE: sort the items in descending order.

void show_array (int data[ ], int n);

void InsertionSort (int data[ ], int n);

void SelectionSort (int data[ ], int n);

where data[] is the array and n is the size of the array.

If you implement both sort routines you will need to make a copy of the original unsorted array before using the first sort, or else the second sort will be working on a sorted version of the array.

Select a Database of your own choice and apply the first three normalization processes. (1NF, 2NF & 3NF)

• The minimum number of records in the table must be 10
• Make sure you carry the same table from 1NF to 2NF and 3NF, do not use separate tables from scratch for all the three forms.
• Brief explanation of the normalization processes must be specified

For this problem, carry at least four digits after the decimal in your calculations. Answers may vary slightly due to rounding.

In a random sample of 70 professional actors, it was found that 42 were extroverts.

(a)

Let p represent the proportion of all actors who are extroverts. Find a point estimate for p. (Round your answer to four decimal places.)
1

(b)

Find a 95% confidence interval for p. (Round your answers to two decimal places.)
lower limit         2
upper limit         3

Give a brief interpretation of the meaning of the confidence interval you have found.

We are 95% confident that the true proportion of actors who are extroverts falls outside this interval. We are 5% confident that the true proportion of actors who are extroverts falls within this interval.     We are 5% confident that the true proportion of actors who are extroverts falls above this interval. We are 95% confident that the true proportion of actors who are extroverts falls within this interval.

(c)

Do you think the conditions n·p > 5 and n·q > 5 are satisfied in this problem? Explain why this would be an important consideration.

Yes, the conditions are satisfied. This is important because it allows us to say that p̂ is approximately binomial. No, the conditions are not satisfied. This is important because it allows us to say that p̂ is approximately binomial.     No, the conditions are not satisfied. This is important because it allows us to say that p̂ is approximately normal. Yes, the conditions are satisfied. This is important because it allows us to say that p̂ is approximately normal.
