Aswimming pool holds 900 cubic meters of water. if its length is 20 meters and its height is 3 meters, find its width

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

Negative 5 1/12 + negative 4 1/4 + 6 3/4
