We have the following general rule for exponents:

then, in this case we have the following:

therefore, the answer is 3
Answer: C.
Simple random sampling
Step-by-step explanation:
A simple random sample in statistics, is a subset of individuals chosen from a larger set. Each individual is chosen randomly and entirely by chance, such that each individual has the same probability for the entire larger set.
Answer:
g(x)=f(x)=12x
Step-by-step explanation:
Since f(x)=g(x) at two points x=−3,−1 , we can tell that g(x) passes through the two points (−3,-32),(−1,−12)
But if g (x)is linear, that means that its graph is a straight line.
And since there is only one way to draw a straight line through two points, there is only one answer for g(x) , and since f(x) is a straight line passing through those two points as well, g(x) has to be equal to f(x)
