Final answer:
The correct answer is a. x = 5, as it is the only value given that is strictly greater than 4 and less than 6, according to the set x .
Step-by-step explanation:
The student's question involves an expression that describes a range of values for the variable x. Specifically, the question asks which value of x satisfies all the conditions given by the set x . Looking at the options provided:
- a. x = 5 falls within the range, as it is greater than 4 and less than 6.
- b. x = 4 does not satisfy the condition since it is not greater than 4.
- c. x = 6 does not satisfy the condition since it is not less than 6.
- d. x = 3 does not satisfy the condition since it is not greater than 4.
Therefore, the correct answer is a. x = 5, as it is the only value that fulfils the condition of being strictly between 4 and 6.
