Carla and Jonah are working together to determine if quadrilateral CDEF with coordinates C(2,3), D(1,2), E(4,1), and F(5, 3) has perpendicular sides. mco = Carla sets up the following equations: 2-3 1-2 1-2 4-1 mos 3 S Jonah sets up the following equations: 2-3 тер 1-2 3-1 5 - 4 mer Who is on track to get the correct answer, and why? O Carla is on the right track because she is finding the slopes of consecutive sides to check for perpendicular sides. O Carla is on the right track because she is finding the slopes of the opposite sides to check for perpendicular sides. O Jonah is on the right track because he is finding the slopes of the opposite sides to check for perpendicular sides. Jonah is on the right track because he is finding the slopes of consecutive sides to check for perpendicular sides.​

The table shows population statistics for the ages of best actor and best supporting actor winners at an awards ceremony. the distributions of the ages are approximately bell-shaped. compare the z-scores for the actors in the following situation. best actor best supporting actor muequals42.0 muequals49.0 sigmaequals7.3 sigmaequals15 in a particular year, the best actor was 59 years old and the best supporting actor was 45 years old. determine the z-scores for each. best actor: z equals best supporting actor: z equals (round to two decimal places as needed.) interpret the z-scores. the best actor was (more than 2 standard deviations above more than 1 standard deviation above less than 1 standard deviation above less than 2 standard deviations below) the mean, which (is not, is) unusual. the best supporting actor was (less than 1 standard deviation below more than 1 standard deviation above more than 2 standard deviations below more than 1 standard deviation below) the mean, which (is is not) unusual.
