Step-by-step explanation: Prediction error refers to the difference between the the actual and predicted value of an observation. Using correlation analysis or study, The level or degree of correlation or relationship between two measured variables usually determines the variation or measure of the prediction error. If there is no relationship or correlation between two measured variables, if such model is used to make prediction, the average prediction error will be very high. However, since it is stated that there exist a relationship between high school GPA and Freshman-year GPA, then making prediction based on this assertion will lessen the average prediction error.

the volume of a large sphere (of radius R) is twice the volume of a smaller sphere (of radius r). form an equation linking r and

Sedaia [141]

Step-by-step explanation:

radius of large sphere is R,

then volume is (4/3)*pie*R³

and

the radius of small sphere is r,

then volume is (4/3)*pie*r³

condition is,

volume of larger sphere is twice of the volume of smaller sphere.

then, (4/3)*pie*R³=2*(4/3)*pie*r³;

R³= 2r³

R=(2^⅓)*r
