Least to greatest \sqrt{x} 4/9, 1/4, 0.6

This is different from the first one can someone me

The brain volumes (cm cubed) of 50 brains vary from a low of 904 cm cubed to a high of 1488 cm cubed. use the range rule of thumb to estimate the standard deviation s and compare the result to the exact standard deviation of 175.5 cm cubed, assuming the estimate is accurate if it is within 15 cm cubed

Which inequality is equivalent to -3x < -12? x < 4 , x < -4 , x > 4, x > -4
