Step-by-step explanation: Edmentum

Answer 2

Answer: B.

Step-by-step explanation

The lowest temperature is the value at which t(h) is the minimum:

As we can see from the graph, this value is approximately 15ºF.

Then, from this point we have to check the hours at which this happens:

Which is approximately 5:00am.
