panic escape. the figure here shows a general situation in which a stream of people attempt to escape through an exit door that turns out to be locked. the people move toward the door at speed vs = 3.000 m/s, are each d = 0.200 m in depth, and are separated by l = 1.900 m. the arrangement in the figure occurs at time t = 0. in time, people become stacked up at the door (a) at what average rate does the layer of people at the door increase? (b) at what time does the layer's depth reach 5.16 m? (the answers reveal how quickly such a situation becomes dangerous.)

there would be 365 different 4 digit numbers

step-by-step explanation:

i belive that it is 365 because i asked google

step-by-step explanation:

i found the life tables for the year 2012. 

life table of males at age 30. probability of dying between ages x and x+1

total population:  

29–30 . . . . . . . . . . . . 0.001030

30–31 . . . . . . . . . . . . 0.001061

non hispanic white population

non hispanic white males

jacob, non hispanic white male. 30 years old.

probability that jacob lives to be 30 years old. 

since the given probabilities are probabilities of dying, i think we simply subtract it from 1 to get the probability of living. we will use the probability of non hispanic white male.

                                          probability of living to be 30 y.o.

29 - 30 : 1 - 0.001477 = 0.998523

30 - 31 : 1 - 0.001503 = 0.998497
