Answer:
(2, -16).
Step-by-step explanation:
(x - 6)(x + 2)
Convert to vertex form:
Expanding the parentheses we have:
x^2 + 2x - 6x - 12
= x^2 - 4x - 12
Completing the square:
= (x - 2)^2 - 4 - 12
= (x - 2)^2 - 16
So the vertex is (2, -16),
Answer:
First number = 33, Second number = -19
Step-by-step explanation:
We can use F to represent the first number and S to represent the second number.
Our two equations then are F + S = 14 and 2F + 3S = 9
We can use substitution:

The given statement is false as using stratified sampling guarantees that members of each group within a population will be sampled.
As given in the question,
Systematic sampling guarantees that members of each group within a population will be sampled is a false statement.
- Systematic sampling represents the probability of sampling method based on the group formed at regular intervals.
- Stratified sampling guarantees each subgroup within the population receives proper representation.
Therefore, the given statement is false as using stratified sampling guarantees that members of each group within a population will be sampled.
