Im Jahr 1856 kündigte Andrew Waugh nach mehrjährigen Berechnungen auf der Grundlage von Beobachtungen des Great Trigonometric Survey an, dass der Mount Everest 8840 m hoch sei. Neuere Erhebungen bestätigen die Höhe mit 8848 m. Berechnen Sie den prozentualen Fehler, der in der früheren Umfrage gemacht wurde.
Hello Rizos!
\(8848m \widehat{=}100\%\\ 8848m-8840m=8m \widehat{=}x\)
\(8848m:100\%=8m:x\\ x\cdot 8848m=8m\cdot 100\%\\ x=\frac{8m\cdot 100\%}{8848m}=0.090416\%\)
\(x=0.09\%\)
The percentage error made in the earlier survey is 0.09%.
