Mopeds (small motorcycles with an engine capacity below 50 cm3) are very popular in europe because of their mobility, ease of operation, and low cost. the article “procedure to verify the maximum speed of automatic transmission mopeds in periodic motor vehicle inspections” (j. of automobile engr.,2008: 1615–1623) described a rolling bench test for determining maximum vehicle speed. a normal distribution with mean value 46.8 km/h and standard deviation 1.75 km/h is postulated. consider randomly selecting a single such moped. a.what is the probability that maximum speed is at most 50 km/h? b. what is the probability that maximum speed is at least 48 km/h? c. what is the probability that maximum speed differs from the mean value by at most 1.5 standard deviations?

It's a snowy day and you're pulling a friend along a level road on a sled. you've both been taking physics, so she asks what you think the coefficient of friction between the sled and the snow is. you've been walking at a steady 1.5m/s, and the rope pulls up on the sled at a 32 ∘ angle. you estimate that the mass of the sled, with your friend on it, is 65 kg and that you're pulling with a force of 80 n .
