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.
Answer:
When dividing two terms with the same base, subtract the exponent in the denominator from the exponent in the numerator: Power of a Power: To raise a power to a power, multiply the exponents. The rules of exponents provide accurate and efficient shortcuts for simplifying variables in exponential notation.

D 6
Step-by-step explanation:
note that (f ￮ g)(x) = f(g(x))
To evaluate f(g(x)) substitute x = g(x) into f(x)
f(g(x)) = f(4x³ + 1)
= 3(4x³ + 1)²
= 3(16
+ 8x³ + 1)
= 48 + 24x³ + 3 ← polynomial of degree 6
The degree of a polynomial is the value of the largest exponent, that is 6
