Answer:
x=8
Step-by-step explanation:
7+5x
so basically what you have to do is take the 7 and subtract from both sides
so like this: 7-7 is 0 so that cancels then 47-7 is 40
then you take 5x and divide 40 by 5
so x=8
hope this helped!

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.
