Concept explainers
This group activity is intended to provide practice in the use of Venn diagrams to sort responses to a survey. The group will determine the topic of the survey. Although you will not actually conduct the survey, it might be helpful to imagine carrying out the survey using the students on your campus.
a. In your group, decide on a topic for the survey.
b. Devise three questions that the pollster will ask to the people who are interviewed.
c. Construct a Venn diagram that will assist the pollster in sorting the answers to the three questions. The Venn diagram should contain three intersecting circles within a universal set and eight regions.
d. Describe what each of the regions in the Venn diagram represents in terms of the questions in your poll.

The trolley position is measured from the center of the bridge rail (x = 0) is given by x(t) = 0.5t^3-6t^2+19.5t-14 : 0 <= t <= 3 min. The trolley moves from point A to B in the forward direction, B to C in the reverse direction and C to D again in the forward direction.

- An Arts group holds a raffle. Each raffle ticket costs $2 and the raffle consists of 2500 tickets. The prize is a vacation worth $3,000. a. Determine your expected value if you buy one ticket. b. Determine your expected value if you buy five tickets. How much will the Arts group gain or lose if they sell all the tickets?arrow_forwardPlease show as much work as possible to clearly show the steps you used to find each solution. If you plan to use a calculator, please be sure to clearly indicate your strategy. Consider the following game. It costs $3 each time you roll a six-sided number cube. If you roll a 6 you win $15. If you roll any other number, you receive nothing. a) Find the expected value of the game. b) If you play this game many times, will you expect to gain or lose money?arrow_forward(20 p) 1.
