Answer to Problem 27E
The statement “ t is at least 10 and at most 22” can be expressed in inequality notation as
The statement “ t is at least 10 and at most 22” can be expressed in interval notation as
Explanation of Solution
Given information: The statement is “ t is at least 10 and at most 22”.
Calculation:
Here, the statement “ t is at least 10 and at most 22” implies that the values of tinclude the number 10, 22 and the numbers that lies between 10 and 22.
It can be represented in inequality notation as
That is, the set of real numbers that are at least 10 and at most 22.
It can be represented in interval notation as
Thus, the statement “ t is at least 10 and at most 22” can be expressed in inequality notation as
