Answer:
6 units²
Step-by-step explanation:
The coordinates (1,1) (1,4) (5,1) form a right triangle as shown in the graph below
The base is is (1,1) and (5,1) so the length is 5-1 or 4 units
The height is (1,1) and (1,4) so the height is 4-1 or 3 units
Area of a triangle is given by
A = 1/2 bh
= 1/2 (4*3)
= 1/2 *12
= 6 units^2
Considering the given probability distributions, distribution D is valid.
<h3>When a probability distribution is valid?</h3>
A probability distribution is valid if:
- There are no negative probabilities.
- The sum of all probabilities is of 1.
In this problem, only distribution D has a sum of 1, hence it is the only valid distribution.

I don't know how to solve 11 but I guess I can solve 12 so I think those are the answers:
12.
(4, 53)
(5, 85)
Answer:
B and C
Step-by-step explanation:
Distribute
4x^2 + 10x = 4x^2 +10x
30x^4 - 12x^3 = 30x^4 - 12x^3
