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.

Answer:
- C
- B
- A
- E
- D
Step-by-step explanation:
1. All numbers on either of lists B or C are all the numbers 1..6, as in choice C.
__
2. Numbers in B that are also in A are just 2 and 4. 6 is not in A. choice B.
__
3. Numbers in both A and C are just the numbers in C. choice A.
__
4. There are no numbers in both B and C, so B∩C is the empty set. Anything intersected with the empty set is the empty set. choice E.
__
5. As in (4), but here, we want the union of A with the empty set. That result will be set A, choice D.
15% * 8 cups
= 0.15 * 8 cups
= 1.2 cups
Let's see if we can't be logical here......Pick a formula and see what it yields. For example, choose D.
For n = 1 ---> -1 x 4^1 ----> -1 x 4 = -4, when the correct value is 1. Therefore D is out.
Try C. For n = 1 ---> 1 x 4^(1-1) ---> 1 x 4^0 ----> 1 x1 ---> 1, So it is correct for n =1. How about
n=2? 1 x 4^(2-1) = 1 x 4^1 = 1 x 4 = 4, when the correct answer is -4. Therefore C is out
I'm sure you can do the remaining two choices....
