Answer: Stratified Random Sample
Step-by-step explanation:
The sample is a stratified random sample in the sense that each of the population that was sampled consisted of the necessary groups that need to be considered in their right proportion of representation which makes the sample valid for us to reasonably draw a conclusion of what to expect in the larger sample space. This sample favours every possible member of the population and helps us adequately plan for all

Answer:
The volume of soil in Darren's planter box is 56 feet³
Step-by-step explanation:
The formula of the volume of a rectangular box is V = l × w × h, where l is its length , w is its width and h is its height
∵ Darren's planter box is seven feet long and four feet wide
∴ l = 7 feet
∴ w = 4 feet
<em>The volume of the soil is equal to the volume of the box using the height of the soil, because the soil takes the shape of the box, so they have the same dimensions of the base</em>
∵ Darren fills the planter box with soil to a height of two feet
∴ h = 2 feet
- Substitute the values of l, w and h in the formula of the volume
∵ V = 7 × 4 × 2
∴ V = 56 feet³
The volume of soil in Darren's planter box is 56 feet³
