A. when are students first expected to work with picture and bar graphs? give the grade level, the domain and summarize the standard that expresses this expectation.

b. at the next grade level, students are expected to expand their understanding of bar graph to a scaled bar graph. give the grade level, the domain and summarize the standard that expresses this expectation.

c. sketch examples of a "single-unit scale bar graph" and a "scaled bar graph" using the techniques from this section to illustrate the standards in parts a. and b. explain your thinking.

this is for mth212 i am just confused with these problems.

Find the value of x for which line a is parallel to line b

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
