Answer:

±sqrt(T*L/m)=v

Step-by-step explanation:

T=mv^2/L

We want to solve the equation for v

Multiply each side by L

T*L=mv^2/L *L

T*L=mv^2

Divide each side by m

TL/m=mv^2/m

T*L/m=v^2

Take the square root of each side

±sqrt(T*L/m)=sqrt(v^2)

±sqrt(T*L/m)=v

Answer:

\large\boxed{v=\pm\sqrt{\dfrac{LT}{m}}}

Step-by-step explanation:

\dfrac{mv^2}{L}=T\qquad\text{multiply both sides by}\ L\\\\L\!\!\!\!\diagup^1\cdot\dfrac{mv^2}{L\!\!\!\!\diagup_1}=LT\\\\mv^2=LT\qquad\text{divide both sides by}\ m\\\\\dfrac{m\!\!\!\!\diagup^1v^2}{m\!\!\!\!\diagup_1}=\dfrac{LT}{m}\\\\v^2=\dfrac{LT}{m}\qquad\text{square root of both sides}\\\\\sqrt{v^2}=\sqrt{\dfrac{LT}{m}}\qquad\text{use}\ \sqrt{a^2}=|a|\\\\|v|=\sqrt{\dfrac{LT}{m}}\Rightarrow v=\pm\sqrt{\dfrac{LT}{m}}

In order to test for the significance of a regression model involving 3 independent variables and 47 observations, the numerator
matrenka [14]

Answer:

The correct option is  C

Step-by-step explanation:

From the question we are told that

     The number of independent variables is  n =  3

     The number of observation is  z =  47

     

Since n is are independent variables then their degree of freedom is  3

   The  denominator(i.e z) degrees of freedom is evaluated as

            Df(z) =  z - (n +1)

          Df(z) =  47 - (3 +1)

          Df(z) =  43

So for the numerator (n) the degree of freedom is  Df(n) = 3

So for the denominator(i.e z) the degree of freedom is  Df(z) = 43
