Answer:

Option d) linear model

Step-by-step explanation:

Given that to create a mathematical model of several data points,  the R2 values of different regression types were identified

The different values of R square is given as follows:

LInear   ...   0.997

Quadratic ... 0.776

Power regression ...0.788

Exponential ... 0.834

R-squared is a statistical measure of closeness the data are to the fitted regression line. It is also named as the coefficient of determination, 100% indicates that the model explains all the variability of the response data around its mean.  And near 100% gives the nearly perfect model.

Here comparing all R square values we find that linear gives the highest R square almost near 1. Hence linear would be used to best fit the data.

D) linear model

Magan bought an electric bill at 85% of the regular price she paid $32.89 for the drill what was the regular price
Natasha2012 [34]

Answer:

$38.69

Step-by-step explanation:

To find the regular price, create a proportion.

\frac{32.89}{x}=\frac{85}{100}

To solve for the regular price x, cross multiply the numerator and denominator of each fraction.

32.89*(100) = x(85)

3289=85x

38.69 = x
