The best sampling strategy would be a stratified sample.
<h3>How are samples classified?</h3>
Samples may be classified as:
- Convenient: Drawn from a conveniently available pool.
- Random: All the options into a hat and drawn some of them.
- Systematic: Every kth element is taken.
- Cluster: Divides population into groups, called clusters, and each element in the cluster is surveyed.
- Stratified: Also divides the population into groups. Then, a equal proportion of each group is surveyed.
For this problem, the 4 different brands of the recorders must be considered, hence the buyers should be divided into groups, and a proportion of each group should be sampled, hence a stratified sample should be used.

Answer7
If it is a slope formula I believe it is y= 4x-24
Given:
Total forest area = 43,000
Old growth trees forest = 0.2%
To find:
The area of the old growth trees.
Solution:
We have,
Total forest area = 43,000
Old growth trees forest = 0.2%
Area of the old growth trees = 0.2% of 43,000
= 
= 
Therefore, the area of the old growth trees is 86 acres.
