Evaluate just means plug in the value that they give you, so instead of r you plug in -1/2
So. 28+79(-1/2)
=28+(-39.5)
= 28-39.5
=-11.5 or -11 1/2

Which of the following are true statements about any regular polygon? Check all that apply.​
Klio2033 [76]

Answer:

A regular polygon has these characteristics:

  • 3 or more sides
  • Closed shape

A polygon can not have one or two sides because that would be a line. It must have more than three sides, or else it is not a polygon.

A polygon is always a closed shape - it can not be an open shape or else it would not be a polygon, it would be considered an outline.

Hope this helps you!

This means that there is researcher involvement and therefore makes this an experiment and not an observational study.

Yes, a case can be made for such a claim. This is because the music being played is the dependent variable in each of the groups. Meaning that the only difference in each of the groups was the music. Therefore, any differences in the data gathered can be connected to the music.
