Find the value of k, if value of r is 0.5. 1 8 1 3 1 2 1 4 Answer (Detailed Solution Below) SpletSo, the slope m 1 of the line y = (2 + 3) x + 4 is 2 + 3. And the slope m 2 of the line y = k x + 6 is k. Step 2: Find the value of k. We know that, if m 1 and m 2 are the slopes of two line and θ is the angle between them, then tan θ = m 2-m 1 1 + m 1 · m 2. Since the angle between the given lines is 60 ° and the slopes of the lines are 2 ...

Splet21. feb. 2024 · There are two conditions the the line to be tangent to the function. 1) the function and the line must intersect. 2) the slope of the tangent line of the function must be the same as the slope of the line y = 4x + 4 For condition 1: If y = k√x and y = 4x + 4 then k√x = 4x + 4 or k = (4x + 4)/√x SpletThe given regression line of y on x is ; y = kx + 4 . And regression line of x on y is x = 4y + 5 . Therefore regression coefficient of y on x = b (y, x) = k . Similarly regression coefficient of x on y = b (x, y) = 4 . But, we know that , b (y, x).b (x, y) = r^2 ==> r^2 = 4k and as 0 0

SpletSubtract the first from the second to obtain 8a+2b=2, or 4a+b=1. The derivative of your parabola is 2ax+b. When x=3, this expression is 7, since the derivative gives the slope of the tangent. So 6a+b=7. So we have. 6a+b=7. 4a+b=1. Subtract the second equation from the first to get 2a=6, or a=3. foundation mental health sioux citySplet10. avg. 2024 · Solution: From given, we have, The two regression lines are: y = 4 + kx and x = 5+4y. The given regression line of y on x is y = kx + 4 . And regression line of x on y is x = 4y + 5 . Therefore regression coefficient of y on x = b (y, x) = k .
