Verified answer ENGINEERING When you make a phone call, the line is busy with probability 0.2 and no one answers with probability 0.3. The random variable X describes the conversation time (in minutes) of a phone call that is answered. X is an exponential random variable with E[X]=3 minutes. Let the random variable W denote the conversation time (in seconds) of all calls (W=0 when the line is busy or there is no answer.) (a) What is $F_{W(w)}$? (b) What is $f_{W}(w)$? (c) What are E[W] and Var[W]? Verified answer ENGINEERING Fresh water is obtained from seawater at a rate of $1.5\ \mathrm{m}^{3} / \mathrm{s}$ by a desalination plant that consumes 11.5 MW of power and has a second-law efficiency of 20 percent. Determine the power that can be produced if the fresh water produced is mixed with the seawater reversibly. Verified answer ENGINEERING Find and graph (on common axes) the partial sums up to Sm0 whose graph practically coincides with that of f(x) within graphical accuracy. State m0. On what does the size of m0 seem to depend? f(x)=J0(α0,1x), α0,1=the first positive zero of J0(x) Verified answer What is the hierarchy of data in database?A hierarchical database is a data model in which data is stored in the form of records and organized into a tree-like structure, or parent-child structure, in which one parent node can have many child nodes connected through links.
Which is the smallest element in data hierarchy?Bit (Character) - a bit is the smallest unit of data representation (value of a bit may be a 0 or 1).
Which of the following is the correct order for storage in a database?Detailed Solution. The correct answer is KB, MB, GB, TB. Storage Capacity of a Computer refers to how much data a computer system can store.
What is highest on the hierarchy of data?The highest level in the hierarchy of data organization is called database. Database is a collection of all tables which contains the data in form of fields. Explanation. Answer : Data base.
