Chana and Josiah started skating at the same time in the same direction, but Josiah had a head start 101010 meters past the starting line. Chana skated 333 meters per second and Josiah skated 222 meters per second.
Here's a graph that shows a system of equations for this scenario where xxx is the number of seconds since Chana and Josiah started skating and yyy is the distance in meters from the starting line.

The weibull distribution is widely used in statistical problems relating to aging of solid insulating materials subjected to aging and stress. use this distribution as a model for time (in hours) to failure of solid insulating specimens subjected to ac voltage. the values of the parameters depend on the voltage and temperature; suppose α = 2.5 and β = 190. (a) what is the probability that a specimen's lifetime is at most 250? less than 250? more than 300? (round your answers to four decimal places.) at most 250 less than 250 more than 300 (b) what is the probability that a specimen's lifetime is between 100 and 250? (round your answer to four decimal places.) (c) what value is such that exactly 50% of all specimens have lifetimes exceeding that value? (round your answer to three decimal places.) hr
