I forgot how to do this it looks hard someone help

Hi there! :)

Use PEMDAS (Parenthesis, Exponents, Multiply, Divide, Addition, Subtraction) to simplify:

We can begin by simplifying the numerator and denominator separately:

6 - 3(2² - 11) + 5 =

Exponents:

6 - 3(4 - 11) + 5 =

Multiplication:

6 - 12 + 33 + 5 =

Add and subtract:

32

Denominator:

Division:

4 - 36÷3 =

Subtraction:

4 - 12 = -8

Resulting fraction:

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.
