Suppose the mean amount of cholesterol in eggs labeled “large” is 186 milligrams, with standard deviation 7 milligrams. Find the probability that the mean amount of cholesterol in a sample of 144 eggs will be within 1.5 milligrams of the population mean.

JamEx Limited requires a program to calculate and print the commission received by a salesperson. The program should process an undetermined number of salespersons and appropriately terminate by a predefined input. The commission rate is based on two factors, the amount of sales and the class to which a salesperson belongs. The input will be the salesperson number, sales amount and class. The commission rate will be based on the following criteria:

Class=1

If sales is equal to or less than $1000, the rate is 6 percent.

If sales is greater than $1000 but less than $2000, the rate is 7 percent.

If the sales is $2000 or greater, the rate is 10 percent.


Class=2

If the sales is less than $1000, the rate is 4 percent.

If the sales is $1000 or greater, the rate is 6 percent.


Class=3 The rate is 4.5 percent for all sales amount


Class=any other value

Output an appropriate error message.

A 5.00-kg object placed on a frictionless, horizontal table is connected to a string

that passes over a pulley and then is fastened to a hanging 9.00-kg object, as in the

figure. Draw free-body diagrams of both objects. Find the acceleration of the two

objects and the tension in the string.



 5. “OptionB” Method 

Create a method called “OptionB” that will print the conversion from miles to kilometres by calling “MilesToKilometers” method (defined in the item #6 below) starting at 10 miles up to 100 miles in increments of 10. Show the result on a table in the console. 

6. “MilesToKilometers” Method 

Create a method called “MilesToKilometers” 

  • Name: MilesToKilometers 
  • • Parameter: o A double representing the miles distance 
  • o A double representing the kilometers distance - this should be an "out" parameter 
  • Returns: Nothing 
  • Displays: Nothing 
  • Task: Calculates the conversion from miles to kilometers. The converted kilometer is returned as an "out" parameter 

Calculate the molar solubility of Al(OH)in a solution that is slightly basic with a pH of 9.50.

Enter your response in scientific notation, e.g. enter 2E3 for 2000.


A 9N force F1 and a 10N force F2 act in the same direction 2i+j-2k and 4i-3j respectively.


a) Find the resultant of the two forces


b)find the total work done if the forces make the object move 2m along the vector S=i+j+k


c)what is the maximum work done that can be achieve if the forces displace the object by 1m?


d)what is unit vector along which the object will move to achieve maximum work done?


f) find F1.F2


g) find F1*F2

Samples of two cards are drawn at random from a population of 6 cards numbered from 1 to 6.




A. How many possible samples can be drawn?




B. Construct the sampling distribution of sample means.

Declare a two-dimensional array with the dimensions needed to store the data for a baseball game. It must store the data of the runs, hits and errors as well as the runs made in each inning (inning) by each team up to 9 innings. The team with the highest score wins.


You must read the data values for each team and then print the data as it appears on the stadium scoreboard, taking into account each possible play that occurs in an inning. If there is a tie they go to extraining and the homeclub in the lower part will win if the visitor is below, but if the visitor exceeds the score in this situation then the visitor wins. The extrainnig will be made up to 13 innings, and if there is still a tie, make the program end with an error message indicating that the relievers are over and therefore the game is also over, which will be decided the next day with whoever scores the first run .
