Use set builder notation to represent the following set: { -3, -2, -1, 0}

Find dy/dx using implicit differentiation ln(20+e^xy)=y

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
