what if class intervals are equal ?

We can take the value of f at a (i.e., f(a)) as first estimate for average value of the function. Divide [a, b] into two equal parts such that then the second estimate of the average value of the function can be taken as second estimate of the average value of the function can be taken as..

The following data is about the ovens sold at an appliance store each day. Which of the following shows the intervals of equal size to group the data? 7 9 12 4 15 10 9 11 14 12 16 18 17 19 21 20 23 22 24 25 => 5-10, 10-15, 15-20, 20-25 or 7-25 or 7-20, 20-25 or 7-15, 20-25..

Dividing [2, 4] into 4 equal intervals, find the value of ∫ 2 4 ln x dx . => 3.7924 or 2.1536 or 3.6192 or 3.0544 or 0.693..

A function f(x) is said to be continuous in an interval I, if it is continuous at each point of I. then x can approach c both from the left and the right and so for f (x) to be continuous at c, we must have If the interval I is the closed interval [a,b], then x cannot ..

Two sets A and B are said to be equal if and only if they contain the same elements i.e. if every element of A is in B and every element of B is in A. We denote the equality by A = ..

Equality of Vectors - Two vectors are said to be equal if they have the same magnitude and direction. In the figure below, three equal vectors have been represented. The equality of vectors is expressed in the following way Since the three vectors have the sa..

Two matrices are said to be equal if they have the same order and their corresponding elements are equal. e.g., then a = 1, b = 2, c = 3, d = 4, e = 5 and f = 6...
