As an estimation we are told 5 miles is 8 km. Convert 60 km to miles.

The table respent two linear functions the equation respented by the first tables is given

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

Divide. write in the simplest form. 4 1/6 divided by 10
