Answer:

$mnb^2 = ac(m+n)^2$

Step-by-step explanation:

Given

$ax^2 +bx + c = 0$

Required

Condition that the roots is in m : n

Let the roots of the equation be represented as: mA and nA

A quadratic equation has the form:

$x^2 + (sum\ of\ roots)x + (product\ of\ roots)=0$

or

$x^2 - (\frac{b}{a})x + \frac{c}{a} = 0$

We have the roots to be mA and nA.

So, the sum is represented as:

$Sum = mA + nA$

$Sum = A(m + n)$

And the product is represented as:

$Product = mA * nA$

$Product = mnA^2$

By comparing:

$x^2 + (sum\ of\ roots)x + (product\ of\ roots)=0$

with

$x^2 - (\frac{b}{a})x + \frac{c}{a} = 0$

$Sum = -\frac{b}{a}$

$Product = \frac{c}{a}$

So, we have:

$Sum = -\frac{b}{a}$

$A(m + n) = -\frac{b}{a}$

Make A the subject:

$A = \frac{-b}{a(m+n)}$

$Product = \frac{c}{a}$

$mnA^2 = \frac{c}{a}$

Substitute $A = \frac{-b}{a(m+n)}$

$mn(\frac{-b}{a(m+n)})^2 = \frac{c}{a}$

$mn\frac{b^2}{a^2(m+n)^2} = \frac{c}{a}$

Multiply both sides by a

$a * mn\frac{b^2}{a^2(m+n)^2} = \frac{c}{a} * a$

$\frac{mnb^2}{a(m+n)^2} = c$

Cross Multiply:

$mnb^2 = ac(m+n)^2$

Hence, the condition that the ratio is in m:n is

$mnb^2 = ac(m+n)^2$

Multicollinearity exists when: a.the dependent variable and an independent variable are highly correlated. b.when two or more in

Papessa [141]

Answer: d all of the above

Step-by-step explanation:

Multicollinearity exists when the dependent variable and an independent variable are highly correlated

Also when two or more independent variables are highly correlated. Even in simple as well as multiple regression models.

The correct answer is all of the above.
