Find the minimum and maximum values of the objective function z=3x+5y

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

Simplify each expression. use positive exponents. show work . (x –2 y –4 x 3 ) –2

Graph the function =gx+2x3 and give its domain and range using interval notation.
