The question I have is that I want to draw without having to drag and then clicking the button whether I want a line or rectangle. It should work first by hitting either the line or rectangle button and then making a drag on the panel with mouse, then after releasing the drag it creates the graphic.

Here is my current code.

package Mod1;

import java.awt.event.*;
import javax.swing.*;

class paintGUI extends JComponent {

    // Image in which we're going to draw
    private Image image;
    // Graphics2D object ==> used to draw on
    private Graphics2D g2;
    // Mouse coordinates
    private int currentX, currentY, oldX, oldY;

    public paintGUI() {
        setDoubleBuffered(false);
        addMouseListener(new MouseAdapter() {
            public void mousePressed(MouseEvent e) {
                // save coord x,y when mouse is pressed
                oldX = e.getX();
                oldY = e.getY();
                System.out.println("Mouse pressed");
            }
        });

        addMouseMotionListener(new MouseMotionAdapter() {
            public void mouseDragged(MouseEvent e) {
                System.out.println("Mouse dragged");

                // coord x,y when drag mouse
                currentX = e.getX();
                currentY = e.getY();
            }
        });
    }

    protected void paintComponent(Graphics g) {
        if (image == null) {
            // image to draw null ==> we create
            image = createImage(getSize().width, getSize().height);
            g2 = (Graphics2D) image.getGraphics();

            // clear draw area
            clear();
        }

        g.drawImage(image, 0, 0, null);
        repaint();
    }

    // now we create exposed methods

    }

    public void thick() {
        g2.setStroke(new BasicStroke(10));
    }

X Company is considering a new processor that costs $150,000. Shipping and setup costs for the new processor are estimated to be $15,000. X’s working capital requirement is expected to increase by $17,000 when the new processor begins operation and is expected to be fully recoverable at the end of the project. The new processor’s useful life is expected to be 5 years and its salvage value at that point is estimated to be $60,000. The new processor is being depreciated using a 5-year ACRS life. Assume a tax rate of 35% and a cost of capital of 12%. Estimated incremental revenues and incremental cash operating expenses for the new processor before tax for each year are shown in the table below. Year Revenues Operating Expenses 1: $87,000 $23,000 2: $82,000 $25,000 3: $93,000 $30,000 4: $87,000 $23,000 5: $88,000 $29,000 The processor will be depreciated to a zero book value using the following annual depreciation rates that are applied to the original installed cost. Year Depreciation % 1: 15 2: 22 3 - 5: 21 A) What is the book value of the new processor at the end of Year 3? B) What is the incremental after-tax cash flows in Year 4? C) What is the total after-tax cash flows in Year 5? Total means incremental cash flows plus terminal cash flows.

As an engineer working for Thomson Pharmaceutical, you are in charge of developing a new cancer drug. The new drug is to be used as a supplement to a well established, currently used drug to reduce tumor sizes in lung cancer patients. Previous studies have shown that the currently-used drug results in an average reduction in tumor mass of 38.7% after 8 weeks of use. To study the effects of the new supplement, you had 16 patients who were given both the current drug and the new supplement drug simultaneously. These patents showed an average 44.7% reduction in tumor mass after 8 weeks (5.92% standard deviation). You also had another 16 patients who were given the current drug along with a placebo (sugar pill) that they thought was the new supplemental drug. This last group showed an average 39.8% reduction after 8 weeks (5.15% standard deviation). In order for development of the new drug to continue, you need to be 99% confident that the supplemental drug is better than the placebo. Determine whether this is true. (Assume the variances are equal for all the studies).

(a) Write the appropriate null, and alternative hypotheses.

(b) Determine the correct pooled statistic (S_p).

(c) Identify the critical region (i.e, the test statistic needs to satisfy what inequality in order to reject the null hypothesis?)

(d) Estimate the p-value for this test. Based on your analysis, can the development of the new drug proceed?

Problem 13-28 Net Present Value Analysis [LO13-2]

Bilboa Freightlines, S.A., of Panama, has a small truck that it uses for intracity deliveries. The truck is worn out and must be either overhauled or replaced with a new truck. The company has assembled the following information:

If the company keeps and overhauls its present delivery truck, then the truck will be usable for five more years. If a new truck is purchased, it will be used for five years, after which it will be traded in on another truck. The new truck would be diesel-operated, resulting in a substantial reduction in annual operating costs, as shown above.

The company computes depreciation on a straight-line basis. All investment projects are evaluated using a 6% discount rate.

Click here to view Exhibit 13B-1 and Exhibit 13B-2, to determine the appropriate discount factor(s) using tables.

Hat Tricks Company (HTC) is a Buffalo, New York, manufacturer of hats and gloves. Recently, the company purchased a new machine to aid in producing the hat product lines. Production efficiency on the new machine increases with the workforce experience. It has been shown that as cumulative output on the new machine increases, average labor time per unit decreases up to the production of at least 3,200 units. As HTC’s cumulative output doubles from a base of 100 units produced, the cumulative average labor time per unit declines by a learning rate of 90%.

HTC has developed a new style of men’s hat to be produced on the new machine. One hundred of these hats can be produced in a total of 10 labor hours. All other direct costs to produce each hat are $25 per hat, excluding direct labor cost. Direct labor cost per hour is $84. Fixed costs are $8,000 per month, and HTC has the capacity to produce 3,200 hats per month.

Required:

HTC plans to set the selling price for the new men’s hat at 200% of direct production cost. If the company is planning to sell 100 hats, what is the selling price? If the plan is to sell 800 hats, what should be the selling price? (Do not round intermediate calculations. Round your answers to 2 decimal places.)

RP owned residential real estate with a $726,000 adjusted basis that was condemned by City Q because it needed the land for a new convention center. RP received $1,028,000 condemnation proceeds for the real estate. Assume that RP would elect to defer gain recognition when possible.

a. Assume RP spent $269,000 of the proceeds to expand its inventory and the remaining $759,000 to purchase new residential real estate. Calculate RP’s gain or loss realized, gain or loss recognized, and tax basis in the inventory and new real estate.

b. How would your answer to part a change if RP’s basis in the condemned real estate were $906,000 rather than $726,000?

c. How would your answer to part a change if RP invested the entire condemnation proceeds plus an additional $132,000 cash in new residential real estate?
