Pam walks along a road which can be modeled by the equation y=3x, where (0,0) represents her starting point. When she reaches the point (7,21), she turns right, so that she is traveling perpendicular to the original road, until she stops at a point which is due east of her starting point (in other words, on the x-axis).

step-by-step explanation:

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.

the 2 figures are congruent bc if you reflect abcd over the y axis then over the d axis the figures overlap

you never say the total so we cant find the percentage used for petrol
