​

Answer 1

Answer:

ans= 3

Step-by-step explanation:

6/2 = 3

12/4=3

15/5=3

21/7=3

Answer 2

Concept:-

In regression analysis, a constant variance refers to the expectation that the standard deviation and variance of the residuals will be constant for all independent variables.

Given:-

We have been given that a table

Find:-

We have to find that the $x$∝$y$ from the given table.

Solution:-

According to the problem

when $x$∝$y$, we get

$\frac{6}{2}=3\\ \frac{12}{4}=3\\\frac{15}{5}=3\\\frac{21}{7}=3$

Final Answer:-

The option $(c) 3$ is right option.
