Calculate the first and second velocities of the car with three washers attached to the pulley, using the formulas v1 = 0. 25 m / t1, and v2 = 0. 25 m / (t2 â€" t1) where t1 and t2 are the average times the car took to reach the 0. 25 and the 0. 50 meter marks. Record these velocities, to two decimal places, in Table E. What is the first velocity of the car with three washers at the 0. 25 meter mark? m/s What is the second velocity of the car with three washers at the 0. 50 meter mark? m/s.

Now max recorded the heights of 500 male humans. he found that the heights were normally distributed around a mean of 177 centimeters. which statements about max’s data must be true? a) the median of max’s data is 250 b) more than half of the data points max recorded were 177 centimeters. c) a data point chosen at random is as likely to be above the mean as it is to be below the mean. d) every height within three standard deviations of the mean is equally likely to be chosen if a data point is selected at random.
