Peter is 2 years older than winnie. peter's age is 16 years less than seven times winnie's age. the equations below model the relationship between peter's age (p) and winnie's age (w):

p = w + 2
p = 7w − 16

which is a possible correct method to find peter's and winnie's ages?

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
