Question

amount consumed each trial vs. time (s)
how many items are consumed at t = 4 s?
8
6
0
3

Explanation:

Step1: Analyze the graph

The graph is a line plot with time (in seconds) on the x - axis and amount consumed each trial on the y - axis. We need to find the value of the amount consumed when \(t = 4\) s.

Step2: Locate \(t = 4\) on the x - axis

Find the point on the x - axis corresponding to \(t=4\) s. Then, look at the y - value of the data point (the dot on the line) at that \(x\) - value. From the graph, when \(t = 4\) s, the amount consumed each trial (y - value) is 6.

Answer:

B. 6
