If the simple interest on a certain sum is 100 per year. Then, S = 100 × x , where x is the number of years. Draw a graph for the above function.

The given function is S = 100 × x Putting x = 1 , 2 , 3 , 4 successively and getting the corresponding value of S . we get the table given below. x 1 2 3 4 S = 100 × x 100 200 300 400 Along the x -axis: Take 1 small square = 1 unit. Along the y -axis: Take 1 small square = 50 units.

If the simple interest on a certain sum is 100 per year. Then, S = 100 × x , where x is the number of years. From the graph, find the value of S , when, x = 7 and x = 4

Draw a histogram to represent the following data. Class Interval 20 - 25 25 - 30 30 - 35 35 - 40 40 - 45 Frequency 45 60 25 30 55

A histogram is a chart that groups numeric data into bins, displaying the bins as segmented columns. They're used to depicting the distribution of a dataset: how often values fall into ranges. Along the x -axis: Take 1 small square = 5 unit. Along the y -axis: Take 1 small square = 5 units.
