The answer is E: I, II, and III
Step-by-step explanation:
The three major features of a well designed experiment are:
1. Replication: If an experiment cannot be replicated, then it is not a well-designed experiment. Replication is one of the major characteristics of a well designed experiment
2. Control: A well designed experiment must have a control. Control, in an experiment, can be referred to as the steps taken to curb the impact of extraneous variables
3. Randomization: Subjects are expected to be randomly assigned to different groups.

A polygon is regular when all angles are equal and all sides are equal (otherwise it is "irregular"). This is a regular pentagon (a 5-sided polygon)
Answer:
y = -2x + 4
Step-by-step explanation:
First, find the slope by doing rise over run. I did this between the points (0, 4) and (2,0) This gives you -4/2 = -2.
Then, find the y-intercept, which is where the line goes through the y axis. This is at y = 4.
So, the equation is y = -2x + 4.
