Note : The Number : 6 denotes no. of terms in a particular option and ^2 - denotes Square ________________________________________________________________________
Take Option (a)
Mean(M) = (1+0+1+0+1+0)/6 = 3/6 = 1/2
SD = Sqroot( 1/6 * [ (1 - 1/2)^2 + (0-1/2)^2+ (1 -1/2)^2 + (0-1/2)^2 + (1 - 1/2)^2 + (0-1/2)^2 ] ) Â Â Â Â Â Â Â Â = Sqroot( 1/6 *Â [ 1/4 + 1/4 +1/4 + 1/4 + 1/4 +1/4] ) Â Â Â Â Â Â Â Â = Sqroot( 1/6 *Â 6 * 1/4 ) Â Â Â Â Â Â Â Â = Sqroot (1/4) = 1/2 = 0.5
Low temperature at the night in a city is 1/3 more than 1/2 high as higher temperature in a day. Sum of the low temperature and highest temp. is 100 degrees. Then what is the low temp?

C Standard Input Output Stream In this C tutorial you will learn about standard input stream and standard output stream explained along with syntax and examples C programming language uses the concept of streams to perform input and output operations using the keyboard and to display information on
Advanced Encryption Standard (AES), also known as US FIPS PUB 197, is a block cipher which has been adopted as an encryption standard by the U.S. government, superseding the Data Encryption Standard (DES).
It is also known as Rijndael, which is a portmanteau of the surnames of the two Belgian crypto
Advanced Mobile Phone System (AMPS) is a first-generation (1G) analog mobile phone system standard developed by Bell Labs and introduced in America in 1983, with variants such as Total Access Communication System (TACS) available in Europe and Japanese Total Access Communication (JTAC) available in
1000BASE-T, or IEEE 802.3ab, is a Gigabit Ethernet wiring standard for Local Area Networks (LAN) that uses copper-based networking hardware as its medium. It is one of the most widely used standards of Ethernet over twisted pair.
The Institute of Electrical and Electronics Engineers Standards Associ
100BASE-T is a subset of Fast Ethernet that refers collectively to a number of Ethernet wiring standards that carry signals at 100Mbps over twisted pair cables. Its IEEE-designated identifier is derived from its characteristics. "100" refers to its rate of transmission of Ethernet
10BASE-T is an Ethernet standard for local area networks (LAN) that requires only one copper twisted pair cable of Category 3 (CAT-3) or higher, either unshielded twisted pair (UTP) or shielded twisted pair (STP), for a maximum network segment length of 100 meters for UTP, or 200 meters for STP.

10BASE5 is an Ethernet standard that requires a specialized coaxial cable to transmit Ethernet frames at a rate of 10Mbps. It is also known as "Thick Ethernet" or "Thicknet" because of the thick coaxial cable it uses, which is 0.375 inches in diameter.
Its desig
10BASE2, or IEEE 802.3, is an early Ethernet Standard that makes use of industry-standard RG-58 coaxial communications cables connected to BNC T-connectors.
10BASE2 gets its identifier, assigned by the Institute of Electrical and Electronics engineers (IEEE), from the following characteristics: &
1xEV-DV, which is short for CDMA2000 1xEV-DV, is a third generation (3G) standard developed to compete against the Evolution-Data Optimized (CDMA2000 1xEV-DO) standard. It was an innovation of a number of cellular wireless telecommunication companies such as Nokia, Motorola, Qualcomm and Lucent.
