A state trooper records the highway speeds of 60 drivers on two different stretches of highway. Stretch 1: minimum-55, Q1-57.5, median-63, Q3-68, maximum-71. Stretch 2: Minimum-60, Q1-63, median-65, Q3-68 maximum-74 outlier-81. 1. What percent of drivers in stretch 1 went faster than 63 mph?
2. How many drivers were going faster than 68 in stretch 2?
3. What is the interquartile range for stretch 2?
4. Which stretch likely has a larger standard deviation?

Can you draw an isosceles triangle with only one 80 degree angle?

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)
