A kite is a quadrilateral with exactly two pairs of congruent consecutive sides. Prove that quadrilateral JKLM with vertices J(1, 5), K(4, 2), L(1, −4), and M(−2, 2) is a kite, and find its area.

The length of time it takes to find a parking space at 9 a.m. follows a normal distribution with a mean of 5 minutes and a standard deviation of 2 minutes. find the probability that it takes at least 8 minutes to find a parking space. (round your answer to four decimal places.)
