The point (-7, -24) is on the terminal ray of angle θ which is in standard position. A student found the six trigonometric values for angle θ. The student’s answers are shown. sin (theta) = StartFraction 24 Over 25 EndFraction. cosine (theta) = negative seven-twenty-fifths. tangent (theta) = negative twenty-four-sevenths. cosecant (theta) = StartFraction 25 Over 24 EndFraction. secant (theta) = negative StartFraction 25 Over 7 EndFraction. cotangent (theta) = negative StartFraction 7 Over 24 EndFraction.

Which value(s) are incorrect?

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)?
