So basically, you take the denominator (the bottom part of a fraction) and see how many times it goes into 75. For example, 3/10= 9/30. Also, you take the number that you multiplied for the denominator and multiply by the numerator too.
The answer would be zero. 0^2=0 and the square root of 0=0
Answer: sigma is used for measuring Population Standard Deviation.
Step-by-step explanation:
The lower case Greek letter 'sigma' is denoted by the symbol (
).
This symbol indicates the Population Standard Deviation of the data. Standard deviation means how much variation or dispersion is there in our data. Squaring of standard deviation gives us Variance which is denoted by the symbol
.
Formula for Population Standard deviation (
) is =
,
where
= each value from our list of data
= Population mean of data
N = Number of observations in our data
Standard deviation can never be negative and it is very much sensitive to outliers in our data.
Step-by-step explanation:
x=4kn+4km
x-4kn=4km
divide both sides by 4k
m=x-n
Answer:
function goes from 4 to -5, soo the answer is -5
