Rational or irrational 4.27 0. -13/1

Answers:

4.27 is rational

0.232342345... is irrational

-13/1 is rational

Explanations:

The fact that 4.27 is a terminating decimal means that we have a rational number. All terminating decimals can be written in a fraction of two integers (positive or negative whole numbers). The word "terminate" means "stop", so the decimal values stop at some point. Note: 4.27 = 427/100 is one way to show that 4.27 is rational

The second value 0.232342345... doesn't seem to have a clear repeating pattern. It's impossible to know what the next value will be. So because of this, the number is irrational. We cannot write it as a fraction of two whole numbers. Other examples of irrational numbers are things like pi = 3.1415... or sqrt(2) = 1.414...

The value -13/1 is rational imply because it is a fraction or ratio of two whole numbers -13 and 1. All fractions like 1/2 or 2/3 or 5/7 are rational numbers. All integers are rational. Note: the denominator can never be zero.

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.

this doesn't make sense lol
