What is the greatest common factor of 25, 50, 75,

The system of equations graphed below has how many solutions? y = 2x + 2

Graph the equation by plotting point x=2

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
