If two regression equations x + 5y = 13 and 3x – 2y = 5, then the mean values of x andy are respectively.(A) (2, 3)(3, 2)(C) (4, 5)(D)(5, 4)

Step 1
We can use the method of substitution or elimination. Here, let's use elimination: Multiply the first equation by 2 and the second equation by 5 to make the coefficients of y the same in both equations: 2x + 10y = 26 15x - 10y = 25 Now, add these two Show more…

Suppose the regression line for a set of data, $\hat{y}=3 x+b$, passes through the point (2,5) . If $\bar{x}$ and $\bar{y}$ are the sample means of the $x$ - and $y$ -values, respectively, then $\bar{y}=$ (A) $\bar{x}$. (B) $\bar{x}-2 .$ (C) $\bar{x}+5$. (D) $\mu_{\bar{x}}$. (E) $3 \bar{x}-1$
