A bag has 5 marbles total in it; 2 red and 3 blue. Step A: Create a tree diagram showing the different possibilities with their
corresponding individual probabilities.
Step B: Make an organized list of the sample space.
Step C: What's the probability of picking a red marble, and then another red
marble?

The position of a moving particle is given by the position function: f(t)=-9t-t^2-0.2t^3+0.1t^4 0 a. at what time does the particle reverse direction? b. when is the displacement positive? (round one decimal place and answer in interval notation) c. when is the displacement negative? (round one decimal place and answer in interval notation) d. when is the particle’s acceleration positive? (round one decimal place and answer in interval notation) e. when is the particle’s acceleration negative? (round one decimal place and answer in interval notation)
