A student while conducting an experiment on Ohm's law, plotted the graph according to the given data. Find the slope of the line obtained.

For a zero order reaction linear plot was obtained for [A] vs t. The slope of the line is equal to:

When the product of pressure and volume is plotted against pressure for a given amount of gas, the line obtained is :

Find the slope of the line passing through the given two point (a, 0) and (0, b)

A teacher analyses the performance of two sections of students in a mathematics test of 100 marks given in the following table. Find the probability that a student obtained less than 20 in the mathematics test.

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 two sections.

A teacher analyses the performance of two sections of students in a mathematics test of 100 marks given in the following table. Find the probability that a student obtained marks 60 or above.
