3. (15 points) two points are selected randomly on a line of length l so as to be on opposite sides of the midpoint of the line. [in other words, the two points x and yare independent random variables such that x is uniformly distributed over (0, l/2) and y is uniformly distributed over (l/2, l). find the probability that the distance between the two points is greater that l/3

answer:

l-4

step-by-step explanation:

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
