0.8x - 0.5 The model P = owing is a learning curve, where P is the proportion of correct responses after x trials. If P =0, there are no correct responses. If P - 1, all learning trials are necessary. responses are correct. The graph of the rational formula is shown below. How many learning trials are necessary for 0.86 of the responses to be correct? Identify This corresponds to the point on the graph. your solution as a point on the graph.
