Example 1:

Previous month, Kim earned salary `$` 1000. This month he earned salary `$` 1200. Calculate the percentage increase in his salary of earnings.

Solution:

Increase salary = `$` 1200 – `$` 1000 =` $` 200

Percentage increase = 200/1000x100%= 20%

The salary earnings percentage increase is 20%.

Answer:

The salary earnings percentage increase is 20%.

Example 2:

A die is tossed once. What the probability of getting the number 2.

Die is tossed once, the sample space is S= {1, 2, 3, 4, 5, 6} and, therefore, n(S)=6..

Consider E1 = event of getting the number 2.

E1= {2} and, therefore, n (E1) =1.

Therefore P (getting 2) = P(E1) = n(E1) / n(S) = `1 / 6`

Answer:

`1/6.`

Example 3:

Rose deposited `$` 7000.00 to invest for 5 years at rate of 6% compound interest. How much amount gets after 5 years?

Here p=`$` 7000, n=5, r=6/100

A = 7000 (1 + 0.06)6 = `$` 2367.58 interest

`$` 700000 is worth` $` 9367.58

Answer:

$ 9367.58

Computer-assisted learning (CAL) is a powerful solution to many of the issues that confront teachers in higher education--the need to innovate in course delivery and to accommodate increasing numbers of students, sometimes at physically distant sites, without an associated increase in resources. On-line, interactive CAL, delivered via the World Wide Web (WWW), is a dynamic open learning resource that has many advantages over pre-authored, fixed platform CAL packages. In addition to their advantages for students, such systems also provide powerful and flexible tools for course administration.

Computer-assisted learning (CAL) provides perhaps the best opportunity for student self-guided learning. It is self-paced and self-planned, with the students themselves choosing their own paths through the mass of information encompassed by the package. Successful use of such packages will not only increase students' knowledge, but will require them to develop other important skills, including self-assessment and planning of studies, information technology skills, creativity, and self-motivation.

Interactive computer-based courseware represents a move towards active learning (i.e., student self-guided teaching) and can be used as a constantly available learning resource for students. The particular virtues of this type of courseware are as follows:

* Availability outside normal class hours, limited only by necessary security arrangements. Documents are constantly available to students anywhere on any computer platform. However, access to any document or set of documents can be easily controlled as required (e.g., unrestricted worldwide access, local access only) and password protected (e.g., sensitive clinical materials).

* Self-administered learning/revision/assessment. Students can set their own pace, with no direct staff involvement, resulting in a considerable efficiency gain.

* Use of visual images. This system can provide a high quality mix of line diagrams, full color images and text, with interaction by means of hypertext indicators. Visual images are an important element in many subject areas; computer based systems allow a degree of interaction not possible by conventional methods (lectures). Recent upgrades to browser technology (e.g., Netscape 3.0 plug-ins, Internet Explorer) extend this capability to in-line video and 3D VRML animations, without imposing any additional training burden on users.

* Selectivity. Hypertext enables individual students either to concentrate on a particular topic or to browse more widely through the subject. The student chooses which topics are to be investigated.

* Adaptability. Unlike expensive cd rom materials, which are platform-restricted and liable to become rapidly outdated, new CAL material can be easily incorporated or present materials can be updated.In its first two years of operation, the flexible, interactive system I have developed has been used extensively by undergraduate students at all levels and is proving to be a popular additional source of detailed factual information and as a method of learning important concepts in biology and medicine. This is an extremely low cost approach to delivery of CAL, which makes maximum use of the HEI's existing investment in network technology.
