An estimated regression equation that was fit to estimate ductility in steel using its carbon content was found to be significan
AnnZ [28]

Answer:

At a level of 95%, it is expected that the interval [0.45; 11.59] contains the value of the ductility in steel when its carbon content is 0.5%.

Step-by-step explanation:

Hello!

Considering the dependent variable:

Y: Ductility in steel.

And the independent variable:

X: Carbon content of the steel.

The linear regression was estimated and a prediction interval was calculated.

The prediction interval is calculated to predict a value that the variable Y (response variable) can take for a given value of the variable X (predictor variable) in the definition range of the linear regression line. Symbolically [Y/X=x_{0}]

In this case 95% prediction interval for Y/X=0.5

At a level of 95%, it is expected that the interval [0.45; 11.59] contains the value of the ductility in steel when its carbon content is 0.5%.

I hope it helps!

IrinaK [193]

Step-by-step explanation:

\sqrt[8]{ {x}^{2}  {y}^{6} }  \\  \\  = ( {x}^{2} {y}^{6}  )^{ \frac{1}{8} }  \\  \\  =  {x}^{2 \times \frac{1}{8}} {y}^{6\times \frac{1}{8}}  \\  \\  = x^{\frac{1}{4}} {y}^{3\times \frac{1}{4}}  \\  \\   = x^{\frac{1}{4}} {y}^{\frac{3}{4}}  \\  \\   =  \sqrt[4]{x {y}^{3} }  \\
