Answer:
18) A: only if you have an additional point not on the line.
19) D: No, because all the points may be on the same line.
Step-by-step explanation:
There are basically 4 ways we can determine a plane and they are;
- When we have three non - collinear points: What this means is that if we have three points that are not on one line, then it means that only one particular plane can pass through those points.
- When we have a line and a point that's not on the line
- When we have two lines that intersect each other.
- When we have two lines that are parallel to each other.
From the four conditions above, we can now answer the question;
18) You can only have a plane if there is an additional point not on the line.
Option A
19) Having just three points may not always be sufficient to have a plane because it's possible that the three points may be on the same line which is not a condition for a plane. Thus, option D is correct.
542.04 = 542
1.88 = 2
542 x 2 = 1084
Three hundred twenty six thousandths
The answer is D. Quadrant IV
To find the percent of the birdhouses occupied, divide the number of occupied birdhouses by how many birdhouses there are in total:

Convert this decimal into a percentage by multiplying by 100:
5.26% of the birdhouses are occupied.
