We have that
using a graph tool--------------> graph the <span> cosecant function
</span>see the attached figure
the answer is the option B
There can be increase or decrease in random samples from a population as it is not always fixed as it will alter most of the time according to statistics
Answer: A.n = 4/7
have:
![n.\frac{-7}{8} =-0.5\\\\n.\frac{-7}{8}=\frac{-1}{2}\\\\n=\frac{-1}{2}:\frac{-7}{8}=\frac{4}{7}](https://tex.z-dn.net/?f=n.%5Cfrac%7B-7%7D%7B8%7D%20%3D-0.5%5C%5C%5C%5C%3C%3D%3En.%5Cfrac%7B-7%7D%7B8%7D%3D%5Cfrac%7B-1%7D%7B2%7D%5C%5C%5C%5C%3C%3D%3En%3D%5Cfrac%7B-1%7D%7B2%7D%3A%5Cfrac%7B-7%7D%7B8%7D%3D%5Cfrac%7B4%7D%7B7%7D)
