Problem 5 0/20 points (graded) You are given a dictionary aDict that maps integer keys to integer values. Write a Python function that returns a list of keys in aDict that map to dictionary values that appear exactly once in aDict. This function takes in a dictionary and returns a list. Return the list of keys in increasing order. If aDict does not contain any values appearing exactly once, return an empty list. If aDict is empty, return an empty list. For example: If aDict

Assume the existence of a bankaccount class. define a derived class, savingsaccount that contains two instance variables: the first a double, named interestrate, and the second an integer named interesttype. the value of the interesttype variable can be 1 for simple interest and 2 for compound interest. there is also a constructor that accepts two parameters: a double that is used to initialize the interestrate variable, and a string that you may assume will contain either "simple", or "compound", and which should be used to initialize the interesttype variable appropriately. there should also be a pair of functions getinterestrate and getinteresttype that return the values of the corresponding data members (as double and int respectively).

Knowing that the central portion of link bd has a uniform cross sectional area of 800 mm2 , determine the magnitude of the load p for which the normal stress in link bd is 50 mpa. (hint: link bd is a two-force member.) ans: p = 62.7 kn
