The cost in dollars, y,to participate x days in a bike tour is a linear function. lin's tour is described by the equation y=5x+50. the cost of max's is $120 for a 14-day bike tour. if both lin and max take 14-day tours, whose bike tour costs less?

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
