Answer:
The constant of variation is 3
Step-by-step explanation:
Given.
![y=81](https://tex.z-dn.net/?f=y%3D81)
![x=27](https://tex.z-dn.net/?f=x%3D27)
And y is directly related to x
∝ ![x](https://tex.z-dn.net/?f=x)
Here k is constant of variation
![y=kx](https://tex.z-dn.net/?f=y%3Dkx)
--------------(1)
Put the
and
value in equation 1.
![k=\frac{81}{27}](https://tex.z-dn.net/?f=k%3D%5Cfrac%7B81%7D%7B27%7D)
![k=3](https://tex.z-dn.net/?f=k%3D3)
So, the constant of variation is 3.
The answer is C, mean =100 and standard deviation=15
