The ABC Toy Company is creating two similar pieces for a board game, as shown below. How could the toy maker confirm that the pieces are similar using the definition of similarity in terms of similarity transformations? Verify segment SR ≅ segment YX and segment ST ≅ segment YZ by translation.

Verify ∠S ≅ ∠Y and ∠T ≅ ∠Z by reflection.

Verify segment SR ≅ segment YX and segment ST ≅ segment YZ by reflection.

Verify ∠S ≅ ∠Y and ∠T ≅ ∠Z by translation.

There are two major tests of readiness for college: the act and the sat. act scores are reported on a scale from 1 to 36. the distribution of act scores in recent years has been roughly normal with mean µ = 20.9 and standard deviation s = 4.8. sat scores are reported on a scale from 400 to 1600. sat scores have been roughly normal with mean µ = 1026 and standard deviation s = 209. reports on a student's act or sat usually give the percentile as well as the actual score. the percentile is just the cumulative proportion stated as a percent: the percent of all scores that were lower than this one. tanya scores 1260 on the sat. what is her percentile (± 1)?
