For the smokestack with the cleaner installed, find the probability that the amount of pollutant in a given sample will exceed 1/2. (d) Given that the amount of pollutant in a sample collected above the smokestack with the cleaner is observed to be 1/2, find the probability that the amount of pollutant exceeds 1.5 above the other smokestack (without the cleaner).

Atype of plant is introduced into an ecosystem and quickly begins to take over. a scientist counts the number of plants after mmonths and develops the equation p(m)= 19.3(1.089)^m to model the situation. most recently, the scientist counted 138 plants.assuming there are no limiting factors to the growth of the plants, about how many months have passed since the plants werefirst introduced? a)o 6.1b)0.6.6c)10 72d)o 23.1
