The table shows the relationship between the number of white shells and the number of pink beads that Aliz uses to decorate 6 different jewelry box. Which of the following equations relates the number of pink beads, p, to the number of white shells, w? �� p = 25w �� w = 52p �� 5w = 2p �� p = 52w

What is the solution to the system of the equations? x = y - 3 x + 3y = 13

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

How can you tell when x and y are not directly proportional?
