rectangle abcd is rotated 180°. what rule shows the input and output of the rotation, and what is the new coordinate of a′?
(x, y) → (−x, −y); a′ is at (5, −1)
(x, y) → (−y, x); a′ is at (−1, −5)
(x, y) → (y, −x); a′ is at (1, 5)
(x, y) → (x, −y); a′ is at (−5, −1)

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
