a study of parents of kindergarteners included 349 who were chosen at random. of these parents, 47% said they sent their child to pre kindergarten. school records show that only 31% of parents sent their children to pre-kindergarten. identify the statistic and the parameter.

option 1

data plot with   3 dots over 33, 1 dot over 34, 2 dots over 35, no dot over 36, 1 dot over 37, 2 dots over 38, 4 dots over 39, and 2 dot over 40.

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8

answer: a

step-by-step explanation: the answer is a due to the rule of symmetry; that a line of symmetry must divide a figure into 2 pieces that are the exact same, only reflected over a line of symmetry. b and c do not have lines of symmetry and would not divide the figure evenly, thus making the answer a.
