Sam and jill decide to explore a city. both begin their walk from the same starting point. (i) sam walks 1 block north, 1 block east, 3 blocks north, and 3 blocks west. (ii) jill walks 4 blocks south, 1 block west, 1 block north, and 4 blocks east. if all city blocks are the same length, who is the farthest distance from the starting point?

Christina can paint 420 square feet in 105 minutes. which unit rate describes the scenario?

Who long does it take to drive 150 miles at 45 miles per hour

Each of the following data sets has a mean of x = 10. (i) 8 9 10 11 12 (ii) 7 9 10 11 13 (iii) 7 8 10 12 13 (a) without doing any computations, order the data sets according to increasing value of standard deviations. (i), (iii), (ii) (ii), (i), (iii) (iii), (i), (ii) (iii), (ii), (i) (i), (ii), (iii) (ii), (iii), (i) (b) why do you expect the difference in standard deviations between data sets (i) and (ii) to be greater than the difference in standard deviations between data sets (ii) and (iii)? hint: consider how much the data in the respective sets differ from the mean. the data change between data sets (i) and (ii) increased the squared difference îł(x - x)2 by more than data sets (ii) and (iii). the data change between data sets (ii) and (iii) increased the squared difference îł(x - x)2 by more than data sets (i) and (ii). the data change between data sets (i) and (ii) decreased the squared difference îł(x - x)2 by more than data sets (ii) and (iii). none of the above
