• Lesson 4: Analyzing Graphs —Water Usage During a Typical Day at School

    EXIT TICKET

    Suppose the researchers collecting data for water consumption during a typical school day collected data through the night too.

    a. For the period between the time the last person leaves the building for the evening and
        the time of the arrival of the first person the next morning, how should the graph of
        water consumption appear?

     

    b.Suppose the researchers see instead, from the time 1:21 a.m. onwards, the graphshows a
        horizontal line of constant value, 4. What might have happened duringthe night?
