the value of a boat, in dollars, x years from its model year can be predicted by the function
f(x)=14,000(0.88)^x

Find an equation for the linear function which has slope -10 and x-intercept -7

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
