The following table gives the distribution of students of two sections according to the marks obtained by them : : Represent the marks of the students of both the sections on the same graph by two frequency polygons. From the two polygons compare the performance of the twosections.

Find the distance between the points (0, 0) and (36, 15), Can you now find the distance between the two towns A and B discussed in Section 7.2.

Direction. In the follwing questions, a statement of assertion is followed by a statement of reason. While answering a question, you are required to choose the correct are out of the given four responses and mark it as (A). If both assertion and reason are true and reason is the correct explanation of the assertion, (B) if both assertion and reason are true but reason is not correct explanation of the assertion. (C) if asssertion is true, but reason if false, (D) if both assertion and reason are false Assertion : The resistance of a wire varies inversely as its area of cross-section. Reason : The resistance of a wire varies inversely as its radius.
