The responding variable is also called the dependent variable. In this experiment, the color of the potato slice at the end of its soaking time is the responding variable. For a simple experiment, such as this, it is best to have one manipulated variable, one responding variable, and everything else contant.he manipulated variable is also called the independent variable. This is what you change. For this experiment, time is the manipulated variable. You would keep each slice of potato in its cup of juice for increasing amounts of time.
Timbuktu, which is on the U.N.-designated World Heritage List, was a seat of Islamic learning for centuries, and its Ahmed Baba library, which was constructed in 2010, was home to 20,000 manuscripts dating back as early as the year 1204. It's still not known how many of the documents were destroyed. Ben Curtis/AP.
C++ Library The C++ library supplied by IBM and this manual is based on the Dinkum C++ Library and the Dinkum C++ Library Reference. Use of this Dinkum C++ Library Reference is subject to limitations. See the Copyright Notice (page 429) for detailed restrictions. A C++ program can call on a large number of functions from the Dinkum C++ Library, a conforming implementation of the Standard C++ library. These functions perform essential services such as input and output. They also provide efficient implementations of frequently used operations. Numerous function and class definitions accompany these functions to help you to make better use of the library. Most of the information about the Standard C++ library can be found in the descriptions of the C++ library headers (page 5) that declare or define library entities for the program. The Standard C++ library consists of 53 headers. Of these 53 headers, 13 constitute the Standard Template Library, or STL. These are
