Web30 okt. 2024 · If the relation between x and y is 5y-3x = 10 and the mean deviation about mean 12, then the mean deviation of y about mean is (a) 7.20 (b) 6.80 (c) 20 (d) 18.80. See answer Advertisement Advertisement kushalsanjeevverma kushalsanjeevverma Answer: 5y-3x=10. 5y=3x (cause measures of dispersion wont be affected by change of origin) 5y ... Web⇒ y2 – 20y + 99 = 0 [Dividing both sides by 3] ⇒ y2 – 11y – 9y + 99 = 0 ⇒ y (y – 11) – 9 (y – 11) = 0 ⇒ (y – 11) (y – 9) = 0 Then, y = + 11 or y = + 9 So, when x = + 10, x < y for y = + 11 and x > y for y = + 9 And when x = – 2, x < y for y = + 11 and x < y for y = + 9 ∴ So, we can observe that one root value of x lies between the root values of y.

What is the difference between linear regression on y with x and x with y?
Web28 apr. 2024 · Step-by-step explanation: Take this as a theorem : If y=a+bx,then the correlation coefficient between X and Y ,r, is +1 if b>0 and is -1 if b<0. That is,it depends on the slope of the given straight line. If it positive,r=+1 and if it negative,r=-1. Now,coming to the given question; Y=-2/3X-4/3. Here,the slope is negative. Hence,r=-1.

How do you solve the system of equations x+ 5y −10 = 0 and x = 2y −8 … Web15 dec. 2011 · If X depends on Y, then regression line is X on Y and X is dependent variable and Y is independent variable. The regression equation Y on X is Y = a + bx, is used to estimate value of Y when X is known. The regression equation X on Y is X = c + dy is used to estimate value of X when Y is given and a, b, c and d are constant. film bully herbig
