Answer:
You can opt to study the entire population when the population is well defined(Complete sampling frame) and small.
It can eliminate any potential bias occurring through sampling technique, but other than that it is really not justified to consume more resources and time.
Answer:
D is the equation of the circle
bearing in mind that an x-intercept is when the graph touches the x-axis and when that happens y = 0, and a y-intercept is when the graph touches the y-axis and when that happens x = 0.

Answer:
3
Step-by-step explanation:
to find the slope you do the formula
y2-y1 divided by x2-x1. (keep it in fraction form). it doesnt really matter what order you put the points as but keep it consistent
