Answer 1

To determine which graph represents the temperatures at which fish for sushi can be stored, we need to consider the meaning of the points and the direction of the shading.

1. A closed circle indicates that the value (41 in this case) is included in the range.
2. An open circle indicates that the value is not included.
3. A shaded arrow pointing to the left suggests that temperatures less than or equal to a certain point (41) are included.
4. A shaded arrow pointing to the right suggests that temperatures greater than or equal to a certain point (41) are included.

For storing fish for sushi, it is typically required that the storage temperature be at or below 41°F. Therefore, the correct representation would be:

• A closed circle at 41 (meaning 41°F is included), with a shaded arrow pointing to the left (indicating all temperatures below 41°F are included).

Thus, the correct response is:

A number line with a closed circle at 41 and shaded arrow pointing to the left.
