Answer:
114540 mature long leaf pines
Step-by-step explanation:
Given that the matured long leaf pine trees in a forest that covers 83 acres.
1 acre = 6 plot
83 acres = 83 × 6 = 498 plots
Among the three and half samples, he actually made use of 3 plots. So,
The first plot contains 212 mature trees, the second plot contains 242 mature trees, and the third plot contains 236 mature trees. That is 3 plots contain
3 plot = 212 +242 + 236 = 690 trees
The number of mature long leaf pines in the entire forest can be estimated as
= 498/3 × 690
= 166 × 690
= 114540 mature long leaf pines in the entire forest.
