Answer:

$138\frac{8}{9}\%$

Step-by-step explanation:

we know that

To find out the corresponding setting to obtain the original from the copy, divide 100% by 72%

$\frac{100}{72}$

Simplify

$\frac{100}{72}=\frac{25}{18}$

Convert to percentage

$\frac{25}{18}(100)=\frac{2,500}{18}\%$

Simplify

$\frac{2,500}{18}\%=\frac{1,250}{9}\%$

Convert to mixed number

$\frac{1,250}{9}\%=\frac{1,242}{9}+\frac{8}{9}=138\frac{8}{9}\%$

ddd [48]

We need the coefficient of determination definition

The coefficient of determination (R²) is a number between 0 and 1 that measures how well a statistical model predicts an outcome. You can interpret the R² as the proportion of variation in the dependent variable that is predicted by the statistical model

So if we have a coefficient of determination of 0.233 we multiply by 100 to get the percentage
