Of course it's possible, because it means that sintheta=-2/5 which satisfies this -1<=sintheta<=1
Answer:
B) The sample size must be greater than 30
Explanation:
According to the central limit theorem the sample size must be greater than 30 in sampling distributions to state that it is approximately normal.
Therefore, the sample size must be greater than 30 for the sampling distribution of the sample proportion of housing units in the large city that are rentals to be approximately normal.
Grow less water-intensive crops.
Prevention is always the best approach. In areas with high evaporation rates and high salinization potential, growing crops with low water demand minimizes the amount of salinization that occurs.
