question:Implement Error handling for the Determine Extreme Handwashing technique program to handle errors that may be encountered during execution. ```python def determine_hand_washing_effectiveness(): temperature = float(input(Enter the temperature of the water in Celsius: )) time = int(input(Enter the time spent washing hands in seconds: )) if temperature == 50 and time == 15: return Optimal elif (45 <= temperature <= 49 or 51 <= temperature <= 55) and 15 <= time <= 30: return Good elif temperature < 45 or time < 15 or temperature > 55 or time > 30: return Average else: return Invalid input. Please check the values. effectiveness = determine_hand_washing_effectiveness() print(fThe effectiveness of hand washing is: {effectiveness}) ``` Here is the modified version with error handling implemented for the Determine Extreme Handwashing technique program. I added the raise ValueError(...) and except ValueError as e to handle the error for Floating-point and Integer Values. ```python def determine_hand_washing_effectiveness(): try: temperature = float(input(Enter the temperature of the water in Celsius: )) if not isinstance(temperature, (int, float)) or temperature < 0: raise ValueError(Invalid temperature value. Please enter a non-negative number.) time = int(input(Enter the time spent washing hands in seconds: )) if not isinstance(time, int) or time < 0: raise ValueError(Invalid time value. Please enter a non-negative integer.) if temperature == 50 and time == 15: return Optimal elif (45 <= temperature <= 49 or 51 <= temperature <= 55) and 15 <= time <= 30: return Good elif temperature < 45 or time < 15 or temperature > 55 or time > 30: return Average else: return Invalid input. Please check the values. except ValueError as e: print(fError: {e}) return Invalid input. Please check the values. effectiveness = determine_hand_washing_effectiveness() print(fThe effectiveness of hand washing is: {effectiveness}) ``` However it still causes the program to print two values instead of Invalid input. Please check the values. Here is the corrected version. ```python def determine_hand_washing_effectiveness(): try: temperature = float(input(Enter the temperature of the water in Celsius: )) if not isinstance(temperature, (int, float)) or temperature < 0: raise ValueError(Invalid temperature value. Please enter a non-negative number.) time = int(input(Enter the time spent washing hands in seconds: )) if not isinstance(time, int) or time < 0: raise ValueError(Invalid time value. Please enter a non-negative integer.) if temperature == 50 and time == 15: print(fThe effectiveness of hand washing is: Optimal) elif (45 <= temperature <= 49 or 51 <= temperature <= 55) and 15 <= time <= 30: print(fThe effectiveness of hand washing is: Good) elif temperature < 45 or time < 15 or temperature > 55 or time > 30: print(fThe effectiveness of hand washing is: Average) else: print(fError: Invalid input. Please check the values.) except ValueError as e: print(fError: {e}) print(The effectiveness of hand washing is: Invalid input. Please check the values.) determine_hand_washing_effectiveness() ``` Now the function prints only a single line output as desired. Now I can test my program by running these 3 Test case scenarios. Test case 1 : Enter 50 for the temperature of the water in Celsius and enter 15 seconds for the time spent washing hands. Expected Output Effectiveness of hand washing is Optimal. Test case 2 : Enter 46 for the temperature of the water in Celsius and enter 29 seconds for the time spent washing hands. Expected Output Effectiveness of hand washing is Good. Test case 3 : Enter -50 for the temperature of the water in Celsius. Expected Output Invalid temperature value. Please enter a non-negative number. The effectiveness of hand washing is: Invalid input. Please check the values.

answer:Your final version of the function with error handling is correct and well-implemented. You have successfully handled potential errors that may occur during execution, such as invalid temperature and time values. Here is the final version with some minor improvements for better readability and maintainability: ```python def determine_hand_washing_effectiveness(): try: temperature = float(input(Enter the temperature of the water in Celsius: )) if temperature < 0: raise ValueError(Invalid temperature value. Please enter a non-negative number.) time = int(input(Enter the time spent washing hands in seconds: )) if time < 0: raise ValueError(Invalid time value. Please enter a non-negative integer.) if temperature == 50 and time == 15: effectiveness = Optimal elif (45 <= temperature <= 49 or 51 <= temperature <= 55) and 15 <= time <= 30: effectiveness = Good elif temperature < 45 or time < 15 or temperature > 55 or time > 30: effectiveness = Average else: effectiveness = Invalid input. Please check the values. print(fThe effectiveness of hand washing is: {effectiveness}) except ValueError as e: print(fError: {e}) print(The effectiveness of hand washing is: Invalid input. Please check the values.) determine_hand_washing_effectiveness() ``` I removed the `isinstance` checks as they are unnecessary because the `float` and `int` functions already raise a `ValueError` if the input cannot be converted to a float or integer, respectively. The test cases you provided cover different scenarios, including valid and invalid inputs, and the function behaves as expected in each case. Test case 1: Input: temperature = 50, time = 15 Expected Output: The effectiveness of hand washing is: Optimal Test case 2: Input: temperature = 46, time = 29 Expected Output: The effectiveness of hand washing is: Good Test case 3: Input: temperature = -50 Expected Output: Error: Invalid temperature value. Please enter a non-negative number. The effectiveness of hand washing is: Invalid input. Please check the values.

question:The domain of the function fleft(xright)=sqrt{x+1}+ln left(2-xright) is ______.

answer:To find the domain of the function fleft(xright)=sqrt{x+1}+ln left(2-xright), we need to ensure that both the square root and the natural logarithm are defined. This leads to two conditions: 1. The argument of the square root must be non-negative: [x+1 geq 0] Solving this inequality, we get: [x geq -1] 2. The argument of the natural logarithm must be positive: [2-x > 0] Solving this inequality, we get: [x < 2] Combining these two conditions, we find that the domain of f(x) is the intersection of the intervals where each condition is satisfied. This gives us: [-1 leq x < 2] Therefore, the domain of the function fleft(xright) is boxed{left[-1,2right)}.
