6 Trout population Suppose 200 trout are caught, tagged, and released in a lake's general population. Let T denote the number of tagged fish that are recaptured when a sample of n trout are caught at a later date. The validity of the mark- recapture method for estimating the lake's total trout popula- tion is based on the assumption that Tis directly proportional to n. If 10 tagged trout are recovered from a sample of 300, estimate the total trout population of the lake.
Reaction time is the time you take from sensing a situation until you apply the brakes Reaction distance is the distance travelled during your reaction time Braking distance is the distance travelled from when you apply the brakes until you stop Stopping distance = Reaction distance + Braking distance Troy was travelling at 75 km/h when he saw an obstacle over the road. His reaction time was 1.6 seconds. a) (i) What was his reaction distance in metres (correct to one decimal place)? (ii) Troy put on his brakes and stopped 23 m later. What was his stopping distance in metres (correct to one decimal place)?
Carbon-14 sa radioactive element with a half-afe of about 5,730 years. Carbon-14 is said to decay exponentialy. The decay rate is 0.000121. We start with one gram of cartbon- 14. We are interested in the time (years) it takes to decay carbon-14. Find the percentage of carben-14 lasting longer than 15,000 years. (0) Sketch the graph, and shade the area of interest.
