7. In a population of 50,000 diploid individuals, what is the probability that a new neutral mutation will ultimately reach fixation? What is the probability that it will ultimately be lost from the population? $K=3X10^{-8}$
2. Import Class a) Implement a class Rectangle with two attributes, width and height. b) Implement an init method with an optional parameter type. Set the default value of the attributes of width and height to 1. c) Implement a display method to print the values of width and height. d) Implement a setWidth method to assign width to the instance variable. e) Implement a setHeight method to assign height to the instance variable. f) Implement a getWidth method to return the value of the instance variable width. g) Implement a getHeight method to return the value of the instance variable height. h) Implement an area method to return the value of area of a rectangle. i) Save Rectangle class as rectangle.py. j) Import Rectangle class from rectangle.py. k) Employs the Rectangle class methods above to set and get various measurements of a rectangle. 1) Instantiate two objects of type rectangle, one with arguments one without. r1 = Rectangle(4, 5) r2 = Rectangle() 2) Call display() to print width and height. 3) Call area() in print() to display the area of r1 and r2. 4) Call setWidth() and setHeight() to update width and height to 6 of r2. 5) Call getWidth() in print() to display the updated width of r2. 6) Call getHeight() in print() to display the updated height of r2. 7) Call area() in print() to display the area of r2. Example Output Width: 4 Height: 5 Area: 20

You observe a species along a steep elevation gradient. Genetic samples indicate the populations differ in genes relating to oxygen consumption. When you transfer individuals gradually from low to high elevation, they become exhausted and eventually die. Their ability to tolerate high altitudes seems to be an example of what?
The parameter of a Poisson random variable, X, is ? = 7.3. a. Determine P(X = 5), P(4? X ?6), and P(X? 2). b. Find the mean and standard deviation of X. a. Determine P(X = 5). P(X=5) = 0.012 (Round to three decimal places as needed.)
Who first proposed that individuals can collectively work to improve society and the general welfare? a. Confucius b. Jean-Jacques Rousseau c. Adam Smith d. Benjamin Franklin

Boat.java Car.java Writing Javadoc with @throws and @requires In the javadoc.txt file, write Javadoc details for the following method: public void setPhoneNumber(String phoneNumber) { for (char c : phoneNumber.toCharArray()) { if (!(Character.isDigit(c) || c == '+' || c == '-' || c == '(' || c == ')')) { throw new InvalidPhoneNumberException("Phone number contains an invalid character"); } } this.phoneNumber = phoneNumber; } You can assume that the method is located in a Contact class, and InvalidPhoneNumberException is correctly defined in another class. Only include the Javadoc comments for the method above. Do not re-declare the method in your solution. Including anything other than Javadoc comments in your solution (e.g. Java code) will cause the tests to fail. You need to: • include a comment at the top explaining the method (at least 4 words) • include the relevant parameter tag(s) • include a \throws tag with the correct exception type and a description • include a \requires tag to specify the precondition that phoneNumber cannot be null • ensure the comment and tags are in the right order • adhere to Javadoc formatting requirements Note: Remember that when a unit test fails, the square brackets are showing the difference between the expected string and the actual string.
3. (a) A 2-mm-diameter wire that is 10 m long is tightly wrapped with a 1-mm-thick plastic cover insulation whose thermal conductivity is 0.15 W/m K. Electrical measurements indicate that a current of 10 A passes through the wire with a voltage of 8 V along the wire. If the insulated wire is exposed to air whose temperature is 30°C with a convective heat transfer coefficient of 24 W/m² K, determine the temperature at the interface between the wire and the plastic cover insulation. (b) (i) Which of these materials will transfer heat faster: Ice? or Water? (ii) Why? [28 points]
