A Binary Number is made up of only 0s and 1s.
110100
Example of a Binary Number
There is no 2, 3, 4, 5, 6, 7, 8 or 9 in Binary!
A "bit" is a single binary digit. The number above has 6 bits.
Binary numbers have many uses in mathematics and beyond.
5 multiplied by 2 is 10Answer:Consider the joke: There are 10 kinds of people in the world those who understand binary and those that don't.Binary uses powers of 2 to express numbers. Thus 20=1,21=2, 22=4 and so on (numbers shown in decimal). This is expressed as strings of numbers using either 0 or 1. Thus 0(binary) =0 (deciamal). 1(Binary)=1 (decimal) or 20, 10(binary)=2(decimal) or 21, 11=3 (decimal) =10+1(binary) = 21+20 and so on.
The binary representations of the decimal numbers from 20 to 30 are as follows: 20: 10100 21: 10101 22: 10110 23: 10111 24: 11000 25: 11001 26: 11010 27: 11011 28: 11100 29: 11101 30: 11110 These binary numbers represent their respective decimal values.
Base 8 is known as octal and base 16 is hexadecimal.. In octal, 0 to 7 are used, so if we counted to 20, the progression would be as follows: 1,2,3,4,5,6,7,10,11,12,13,14,15,16,17,20,21,22,23,24 In hexadecimal, the numbers 0-9 are used and the letters A-F are used. Counting to 20 would be as follows: 1,2,3,4,5,6,7,8,9,A,B,C,D,E,F,10,11,12,13,14
The binary numbers from 1 to 20 are...1 = 12 = 103 = 114 = 1005 = 1016 = 1107 = 1118 = 10009 = 100110 = 101011 = 101112 = 110013 = 110114 = 111015 = 111116 = 1000017 = 1000118 = 1001019 = 1001120 = 10100
The number 20 in binary is 10100
15 = 111116 = 10000 17 = 10001 18 = 10010 19 = 10011 20 = 10100
Decimal 20 is 10100 in binary
To factorise is to find the numbers that divide into the original number by only using prime numbers. For example factorise 20 = 2 times 2 times 5
23 29 31 37 41 43 47
The number "10001" is the number 17 in binary (base two). 24 + 20 = 16 + 1 = 17
In any given set, the mean is the average, which is the total of the numbers divided by how many numbers there are. Ex. (10, 17, 20, 45, 68) 68 + 45 + 20 + 17 + 10 = 160 There are 5 numbers in this set. 160/5 = 32 The mean is 32.
add up all the numbers you have then divide by the amount of numbers you haveThe mean is the same as the average. You must add up all the data, then divide by the number of data entries you added. E.g. 3+5+2+6+4=20 then 20 divided by 5 = 4, so in this case 4 is the mean.
