Question

My daughter is a Girl Scout and it is time for our cookie sales. There are 15 neighbors nearby and she plans to visit every neighbor this evening. There is a 40% likelihood that someone will be home. If someone is home, there is an 85% likelihood that person will make a purchase. If a purchase is made, the revenue generated from the sale follows the Normal distribution with mean $18 and standard deviation $5. Using @RISK, simulate our door-to-door sales using at least 1000 iterations and report the expected revenue, the maximum revenue, and the average number of purchasers. What is the probability that the revenue will be greater than $120?

Monkey face and hand in JavaFX Application

Program Plan:

• Import required package.

• Define “enum” class for monkey hand position.

• Define “drawMonkeyFace” class.

○ Initializes required variables.

○ Define main function.

○ Define “drawFace” method with argument of “GraphicsContext” object, “at_XBase”, “at_YBase” and “HandPosition” object.

■ Invoke “strokeOval” method for object “gContext”.

■ Compute the monkey ear width, height and offset to draw the monkey ear.

■ Invoke “strokeOval” method for object “gContext”.

■ Compute the monkey eye width, height and offset to draw the monkey eye.

■ Invoke “strokeOval” method for object “gContext”.

■ Compute the monkey mouth width, height and offset to draw the monkey mouth.

■ Invoke “strokeArc” for object “gContext” which is used to draw arc.

■ Declare required variables for hand offset.

■ Check location of hand using “switch” case.

• If the case is “MONKEY_MOUTH”, then compute hand offset for “X” and “Y” and then call “drawMonkeyHand” method.

• If the case is “MONKEY_EYE”, then compute hand offset for “X” and “Y” and then call “drawMonkeyHand” method.

• If the case is “MONKEY_EAR”, then compute hand offset for “X” and “Y” and then call “drawMonkeyHand” method.

○ Define “drawMonkeyHand” method with argument of “GraphicsContext” object, “at_XBase” and “at_YBase”.

■ Compute palm width and height.

■ Invoke “fillOval” method for object “gContext”.

■ Compute finger width, height of monkey and offset.

■ Invoke “fillOval” method for object “gContext”.

○ Define “start” method.

■ Create an object “rt” from “Group” class.

■ Create an object “s” from “Scene” class.

■ Create an object “ca” from “Canvas” class.

■ Create object for “GraphicsContext” class.

■ Draw monkey ear by calling method “drawFace”.

■ Set the font by using the method “setFont”.

■ Set text for first monkey face by using method “fillText”.

■ Draw monkey eye by calling method “drawFace”.

■ Set text for second monkey face by using method “fillText”.

■ Draw monkey mouth by calling method “drawFace”.

■ Set text for third monkey face by using method “fillText”.

■ Set title for given program.
