Question

Which scenario can be modeled using the graph below?

A temperature range is within 5 degrees of 60 degrees Fahrenheit.
A scientist uses more than 55 and less than 65 mL of water in an experiment.
A commuter train takes less than 55 minutes or more than 65 minutes to complete one route.
A worker makes greater than $55 per day but less than $65 per day.

Answer 1

A

Explanation:

A temperature range is within 5 degrees of 60 degrees Fahrenheit.

Answer 2

Looking at the number line, it is visible that the circular marks at the ends of the shaded region are shaded as well, not empty. This indicates that the values that these marks lie on, 55 and 65, must be included in the range. The only option that fits this is A, a temperature range within 5 degrees of 60 degrees Farenheit. This is because 5 degrees less than 60 degrees is 55, while 5 degrees greater than 60 is 65 degrees.
