The table below shows the average SAT math scores from 1993-2002 Using the data from the table determine if there is a linear trend between the year and the average SAT math scores and determine if there is an exact linear fit of data. Describe the linear trend if there is one.

a. Positive linear trend, an exact linear fit.
b. Positive liner trend, not an exact linear fit.
c. Negative liner trend, not an exact linear fit.
d. Negative linear trend, an exact linear fit.

Consider the following geometry problems in 3-space enter t or f depending on whether the statement is true or false. (you must enter t or f -- true and false will not work.) f equation editorequation editor 1. a plane and a line either intersect or are parallel t equation editorequation editor 2. two planes parallel to a third plane are parallel f equation editorequation editor 3. two lines either intersect or are parallel f equation editorequation editor 4. two planes orthogonal to a third plane are parallel f equation editorequation editor 5. two planes orthogonal to a line are parallel f equation editorequation editor 6. two planes either intersect or are parallel f equation editorequation editor 7. two lines orthogonal to a third line are parallel t equation editorequation editor 8. two lines parallel to a third line are parallel t equation editorequation editor 9. two planes parallel to a line are parallel f equation editorequation editor 10. two lines parallel to a plane are parallel f equation editorequation editor 11. two lines orthogonal to a plane are parallel
