Step-by-step explanation:
The sampling methods include:
1. Simple random sampling: Here, the individuals in the population have an equal chance of being selected as the selection is done randomly and anyone can be picked from the population
2. Systematic sampling: This is when the selection of the individuals is done at regular intervals. For example from the population, every 10th person might be picked.
3. Stratified sampling: Here, the total population is first divided into a smaller group called the strata before the sampling is done.
4. Clustered sampling: Here, the sampling unit is the subgroups of the population and not the individuals.
Answer:
In a general point (x, y) the horizontal component is the x-component, and the vertical component is the y-component.
then if we have the points (a, b) and (c, d)
The vertical distance or change between these points will be the difference between the y-components, and the horizontal distance or change is the difference between the x-components.
Then the vertical change between the points (2.5 , 1) and (5, 2) is:
2 - 1 = 1 unit.
The horizontal change between the points (2.5, 1) and (5, 2) is:
5 - 2.5 = 2.5 units.
A= l * W (area = length times width)

if you can provide the figure it would be quite easy for the people giving answers
