Answer:

5, 10 and 16

Explanation:

The sum of their ages is √961 = 31

If Joe is x years old, the equation that follows is:

x + (x+5) + (x+5+6) = 31

This simplifies to

3x = 31 - 11 - 5 = 15

so x=5

From that you can find

Joe = x = 5

Kate = x+5 = 10

Jody = x+5+6 = 16

  2. states = {
  3.    "Alabama": "Montgomery",
  4.    "California": "Sacramento",
  5.    "Florida": "Tallahassee",
  6.    "Hawaii": "Honolulu",
  7.    "Indiana": "Indianapolis",
  8.    "Michigan": "Lansing",
  9.    "New York": "Albany",
  10.    "Texas" : "Austin",
  11.    "Utah" : "Salt Lake City",
  12.    "Wisconsin": "Madison"
  13. }
  14. correct = 0
  15. wrong = 0
  16. round = 1
  17. while(round <= 5):
  18.    current_state = random.choice(list(states))
  19.    answer = input("What is the capital of " + current_state + ": ")
  20.    
  21.    if(answer == states[current_state]):
  22.        correct += 1
  23.    else:
  24.        wrong += 1
  25.    
  26.    round += 1
  27. print("Correct answer: " + str(correct))
  28. print("Wrong answer: " + str(wrong))

Explanation:

The solution code is written in Python 3.

Line 3 -14

Create a dictionary of US States with capital as each of their corresponding value. Please note only ten sample states are chosen here.

Line 16 - 18

Create variables to track the number of correct and inaccurate response and also round counter.

Line 19 - 28

Set the while condition to enable user to play the quiz for five questions and use random.choice to randomly pick a state from the dictionary and prompt user to input the capital of selected stated.

If the answer matched with the capital value of the selected state, increment the correct counter by one. Otherwise the wrong counter will be incremented by one. Increment the round counter by one before proceed to next round.

Line 30 - 31

Print the number of correct responses and wrong responses.

Consider the eight bit signed binary number 1110 0101. Convert it to signed decimal from assuming the signed binary number is re
lapo4ka [179]

Answer:

-26

Explanation:

The given binary number is 1110 0101. Also given that the signed binary number is represented using one's compliment.

We begin by computing the 1s complement representation of 1110 0101 by inverting the bits: 00011010

Converting 00011010 to decimal, it corresponds to 26.

So the 1s complement of the original number is 26. This means that the original number was -26.
