Answer:
x = - 1 and x = 5
Step-by-step explanation:
Given
(x - 3)² + 2(x - 3) - 8 = 0
Let u = x - 3, then
u² + 2u - 8 = 0 ← solve for u
(u + 4)(u - 2) = 0 ← in factored form
Equate each factor to zero and solve for u
u + 4 = 0 ⇒ u = - 4
u - 2 = 0 ⇒ u = 2
Convert back to x, that is
x - 3 = - 4 ( add 3 to both sides ) ⇒ x = - 1
x - 3 = 2 ( add 3 to both sides ) ⇒ x = 5
The answer is C. Systemic random sampling.
By definition, systemic random sampling is a sampling technique where the respondents are selected according to a <em>random starting point </em>(this alone shows that the answer is C.) The researcher then chooses the sample interval, which is the difference between two consecutive numbers in the progression.
In this case, the starting point is 8 and the sample interval is 10.
The answer is C.
