Concept explainers
Formulas with rational expressions are often used to model learning. Many of these formulas model the proportion of correct responses in terms of the number of trials of a particular task. One such model, called a learning curve, is
where P is the proportion of correct responses after x trials. If
, there are no correct responses. If
, all responses are correct. The graph of the rational formula is shown. Use the formula to solve Exercises 103-104.
How many learning trials are necessary for 0.95 of the responses to be correct? Identify your solution as a point on the graph.

- Sales Barnes & Noble had annual sales of $6.8 billion in 2013 and $6.1 billion in 2015. Use the Midpoint Formula to estimate the sales in 2014. Assume that the annual sales followed a linear pattern.arrow_forwardGraph on the number line: (a) x2 (b) x3 (c) x1arrow_forwardDemand for Candy Bars In this problem you will determine a linear demand equation that describes the demand for candy bars in your class. Survey your classmates to determine what price they would be willing to pay for a candy bar. Your survey form might look like the sample to the left. a Make a table of the number of respondents who answered yes at each price level. b Make a scatter plot of your data. c Find and graph the regression line y=mp+b, which gives the number of respondents y who would buy a candy bar if the price were p cents. This is the demand equation. Why is the slope m negative? d What is the p-intercept of the demand equation? What does this intercept tell you about pricing candy bars? Would you buy a candy bar from the vending machine in the hallway if the price is as indicated. Price Yes or No 50 75 1.00 1.25 1.50 1.75 2.00arrow_forward
- Using your graphing calculator, make a scatter plot of the data from the table. Then graph your model from Question 2 along with the data. How well does your model fit the data? What could you do to try to improve your model?arrow_forwardA professor of economics gives multiple choice exams each semester. He curves the exams by giving the maximum possible points to the highest non-zero score on the exam.1 For example, if a 50 question exam is worth 100 points and the top score in the class is 40, then each question is worth 100/40 = 2.5 points if answered correctly and 0 otherwise. Grades are then awarded as follows: 65% or better = "excellent", 48% or better = "good", 34% or better = "satisfactory", and below 34% = "fail".A. Suppose that all students know the correct answer to the first question in the exam - because the professor ALWAYS takes it from the previous year's exam paper - but have no idea what the other questions will be. Could the students form a cartel (sustainable or not) to ensure that each student received an "excellent" for the exam?B. Would a student who was concerned with relative class standing have an incentive to cheat? C. Is it likely that such a cartel would be successful in a large class?arrow_forwardDraw a graph that pictures the following situation. Identify the independent and dependent variables. Determine the intervals on which the dependent variable is increasing, decreasing, or constant. A woman left her office at 7:30 to attend a meeting. After walking for 3 minutes, she realized she forgot her notes and returned to get them. She picked up her notes and resumed her walk to the meeting, arriving at 8:00. After 14 minutes, the meeting was over and the woman returned to her office. Assume that the woman walks from the place of the meeting back to her office at the same speed with which she walks from her office to the place of the meeting after picking up her notes. Draw a graph that pictures the given situation. Choose the correct graph below. OA. OB. Oc. OD. AD AC Identify the independent and dependent variables. O A.
