Answer:
349.94
Step-by-step explanation:
First u add all the square sides because they all are the same which gives u 196 then u can see there is two half circles which if they add up will be a circle and the diameter is the same as the square sides then if the diameter is 14 then the radius will be 7 becaue 14/2 therefore u use the area of the circle which is
then u add all the numbers.

Answer:
The numerical value of the correlation between number of classes skipped and grade index is 0.60.
Step-by-step explanation:
In statistics R² is a measure that is used to determine the proportion of variation in the dependent variable that can be explained by the independent variable. The value of R² is compute by squaring the correlation coefficient (<em>r</em>) between the dependent and independent variable.
In this case the dependent variable is the grades and the independent variable is the number of classes skipped.
The R² between the grades and the number of classes skipped is 36% or 0.36.
Compute the value of <em>r</em> as follows:
Thus, the correlation between number of classes skipped and grade index is ±0.60.
