Los alumnos de segundo año realizaron un experimento con la profesora de Biología. En la primera etapa del experimento lograron congelar una sustancia que originalmente estaba a 30° C y la llevaron a 7° C bajo cero. En la segunda etapa lograron enfriar la sustancia 15 grados más. ¿cuántos grados tuvieron que enfriar la sustancia en la primera etapa?, ¿ qué temperatura alcanzó en la segunda etapa?

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)?
