2x - y = -2

x - 2y = 53x + 2y = 10

5x - 2y = 63x + y = 3

2x + 4y = 225x - 2y = -19

3x + y = -7x - y = -3

x + y = -7y = -2x

3x - y = 10y = 2x - 9

y = x - 5y = x - 2

2x - 3y = -5

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

David estimated he had about 20 fish in his pond. a year later, there were about 1.5 times as many fish. the year after that, the number of fish increased by a factor of 1.5 again. the number of fish is modeled by f(x)=20(1.5)^x. create a question you could ask that could be answered only by graphing or using a logarithm.
