What number can you add to to get a rational number?

Question says about what number can you add to

to get a rational number.

We know that rational numbers are the numbers which are written in form of p/q where p and q both are integers.

but q can never be 0.

If we add only some integer or real number to then we will still get irrational number which is not of the form p/q.

so the only way to finish the radical part is to use the opposite of that which is -

As you can see that

- = 0

and we know that 0 is a rational number because that can be written as 0/1 in p/q form.

Hence final answer is -

step-by-step explanation:

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.
