Suppose that the number of drivers who travel between a particular origin and destination during a designated time period has a poisson distribution with parameter m 5 20 (suggested in the article "dynamic ride sharing: theory and practice," j. of transp. engr., 1997: 308–312). what is the probability that the number of drivers will

The swimming pool is open when the high temperature is higher than 20∘c. lainey tried to swim on monday and thursday (which was 33 days later). the pool was open on monday, but it was closed on thursday. the high temperature was 30 ∘c on monday, but decreased at a constant rate in the next 33 days. write an inequality to determine the rate of temperature decrease in degrees celsius per day, d, from monday to thursday.

Write the point-slope form of the line passing through (2, -12) and parallel to y=3x.

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.
