It is given that the inequalities.
We need to determine the inequalities which have an open circle.
The graph will have an open circle only if it has the symbol < or > because it indicates that the boundary is not included.
<u>Option A</u>:
The inequality shows that it contains the boundary point 25.
Hence, the inequality does not have an open circle.
Hence, Option A is not the correct answer.
<u>Option B</u>:
The inequality shows that it contains the boundary point -2.5.
Hence, the inequality does not have an open circle.
Hence, Option B is not the correct answer.
<u>Option C</u>:
The inequality shows that it does not contains the boundary point 5.4
Hence, the inequality have an open circle.
Thus, Option C is the correct answer.
<u>Option D</u>:
The inequality shows that it does not contain the boundary point
Hence, the inequality have an open circle.
Thus, Option D is the correct answer.
<u>Option E</u>:
The inequality shows that it does not contain the boundary point 0
Hence, the inequality have an open circle.
Thus, Option E is the correct answer.
