Find the probability that a randomly selected point within the circle falls in the white area

F(x)=|x| is shifted down 4 units and to the right 3 units.

What could explain what happened when the time was equal to 120 minutes

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
