Ahiker is lost in the woods. a search team has created a coordinate grid to represent the woods. each unit on the grid is one square mile. the hiker was last seen at (4, -9) and could have walked 10 miles in any direction since then. which equation represents the area the hiker could be in? a) (x - 4)2 + (y + 9)2 = 102 b) (x + 4)2 + (y - 9)2 = 102 c) (x + 4)2 + (y + 9)2 = 1002 d) (x - 4)2 + (y - 9)2 = 1002

Ahypothesis is: a the average squared deviations about the mean of a distribution of values b) an empirically testable statement that is an unproven supposition developed in order to explain phenomena a statement that asserts the status quo; that is, any change from what has been c) thought to be true is due to random sampling order da statement that is the opposite of the null hypothesis e) the error made by rejecting the null hypothesis when it is true
