On the number line, (x) satisfies (-1<x<0) and \(x^2=\frac{1}{9}\). What is (x)?
B. \(-\frac{1}{3}\)
\(x^2=\frac{1}{9}\) से \(x=\pm\frac{1}{3}\), और दिए गए अंतराल में ऋणात्मक मान चाहिए। परीक्षा में शर्तों से सही चिह्न चुनें। / From \(x^2=\frac{1}{9}\), \(x=\pm\frac{1}{3}\), and the given interval needs the negative value. In exams, use conditions to choose the correct sign.

A. क्योंकि कर्ण \(\sqrt{1^2+1^2}=\sqrt{2}\) होता हैBecause the hypotenuse is \(\sqrt{1^2+1^2}=\sqrt{2}\)
पाइथागोरस प्रमेय से कर्ण \(\sqrt{2}\) मिलता है। परीक्षा में सुरद निर्माण के लिए कर्ण को संख्या रेखा पर स्थानांतरित करें। / By Pythagoras theorem, the hypotenuse is \(\sqrt{2}\). In exams, transfer the hypotenuse length to the number line for surd construction.

Which number lies exactly midway between \(\frac{2}{7}\) and \(\frac{3}{7}\) on the number line?
C. \(\frac{5}{14}\)
बीच की संख्या औसत होती है, इसलिए \(\frac{\frac{2}{7}+\frac{3}{7}}{2}=\frac{5}{14}\)। परीक्षा में दो संख्याओं के बीच मध्य मान निकालें। / The middle number is the average, so \(\frac{\frac{2}{7}+\frac{3}{7}}{2}=\frac{5}{14}\). In exams, find the mean for the midway value.
