X² = 144
work:
solution:
rational
or
irrational

x = 12

Step-by-step explanation:

To find x, take the square root of both sides, canceling out the square of x and turning the expression to x = 12, because the square root of 144 is 12. To check, square 12 or multiply 12 by itself, taking you back to 144.

The solution is rational because it can be made by dividing two integers, 144 and 12

c

step-by-step explanation:

it isn't d, because the interquartile range is from 27-57. and the interquartile range is basically half the data, it's pretty obvious.

it isn't b, because like i said earlier, the interquartile range is from 27-57. 57-27 is 30. the real range has to be longer

not a either. although it looks like it, 3/4 of the data is not greater than 27. but if c is wrong than this should be correct

the correct answer is c, because 13 is the point in which the plot starts
