Give one example of when you would make a frequency table to solve the problem

RideAnS [48]

Answer:

Consider a class in which there are 40 students .There is a Mathematics test of 50 marks .Two students were absent.The Duration of test was for one and half an hour.

So Marks of students according to their roll number are 12,8,4,20,25,36,2,29,35,39,5,48,43,37,38,29,17,15,15,25,31,32,26,28,27,24,2,15,34,,50,46,48,37,28,26,45,49,24.

So in this case it would be better to prepare frequency polygon by selecting a class interval.

Class interval = 0-5,5-10,10-15,15-20,20-25,25-30,30-35,35-40,40-45,45-50.

Or 0-10,10-20,20-30,30-40,40-50.

or you can make class interval by yourself.

Which equation shows the point slope form of the line the glasses through (3,2) and has a slope of 1/3

7nadin3 [17]

The equation of a line in ' point- slope form ' is

y - b = m( x - a )

where m is the slope and (a, b ) a point on the line

here m = $\frac{1}{3}$ and (a, b ) = (3, 2 )
