Final answer:
To check if a number is even, use the modulo operator. To check if multiple conditions are true, use the logical AND operator.
Step-by-step explanation:
To write an expression that evaluates to True if the value associated with x is even, but False if the value is odd, you can use the modulo operator.
The modulo operator returns the remainder of a division operation. If the remainder is 0, then the number is even. Here is the expression: x % 2 == 0.
For the second part of the question, to check if temperature is greater than 90 and humidity is less than 10, you can use the logical operators 'and' and comparison operators. Here is the expression: temperature > 90 and humidity < 10.
