What does square brackets mean?
It means indexing into an array. The array could be an array of built in primitive types or array of objects. The index must be a numeric value greater than or equal to 0.

Define bit in microprocessor?
: A Bit is a digit in the binary number system. It can have two values, 0 or 1. In computer RAM and ROM memory, a bit is a small electrical switch which is either on (value 1) or off (value 0).
What does it mean for a number to be in scientific notation?
It's usually related to large numbers - For example... 1,000,000,000 in scientific notation is 109 - which as you can see takes up much less space.
If the null hypothesis states that there is no difference between the mean income of males and the mean income of females then the test is one-tailed?
Falseà Ha:µM-µF=0 and Ha:µM-µF≠0
What is the maximum and RF value can be?
The maximum RF value that can be obtained is 1.0. This means that the substance travels the full distance of the chromatography medium being used. Any RF value greater than 1 is not physically possible.
Is rf value is negative or not?
The RF value, or retention factor, is a measure used in chromatography to indicate the relative distance traveled by a compound compared to the solvent front. By definition, RF values range from 0 to 1, where 0 indicates that a compound did not move from the origin and 1 indicates that it moved with the solvent front. Therefore, RF values cannot be negative.
What are largest and smallest Rf values?
The largest Rf value is 1, which occurs when the compound remains at the origin of the chromatogram and does not move at all. The smallest Rf value is 0, which happens when the compound moves with the solvent front and does not adhere to the stationary phase.
How do you solve the Rf value in Column Chromatography?
Measure the distance from your marked pencil line to the solvent front. Also measure the distance fomr the marked pencil line to the middle of the spot, and divide this by the first distance. This value will be between 0 and 1.
What is the value of a 'z' score of 0?
A z-score of 0 means the value is the mean.
Is -12 greater than 0?
When 24 > 9. Is it a minimum value or maximum value?
What does a signed data type mean?
signed: its value can be less than zero unsigned: its value cannot be less than zero example: 16 bit signed: -32768 .. 32767 16 bit unsigned: 0 .. 65535
Why can't an RF value of more than 1 be calculated?
An RF (retention factor) value greater than 1 cannot be calculated because it represents the ratio of the distance traveled by a compound to the distance traveled by the solvent front on a chromatography plate. If a compound travels further than the solvent front, it suggests that the compound has not interacted properly with the stationary phase, which is not a valid scenario in chromatography. Therefore, RF values are always between 0 and 1, indicating that the compound can only travel a distance equal to or less than the solvent front.
How do you find the absolute value of something?
If a number is not less than zero then that is its absolute value. If a number is less than zero, its negative is its absolute value. So, if |x| denotes the absolute value of x, then |x| = -x for x<0 [since if x<0 then -x>0] and |x| = x for x>= 0
How much error is expected between the sample mean and population mean?
0. The expected value of the sample mean is the population mean, so the expected value of the difference is 0.
What does it mean by numeric value?
Numerical value = absolute value For any real number a, the absolute value of a, denoted by |a| is itself if a ≥ 0, and -a if a < 0. Thus |a| is positive expect when a = 0.
What does differ by 0 mean?
Have the same value.
