Suppose a simple random sample of size nequals49 is obtained from a population with mu equals 78 and sigma equals 7. ​(a) Describe the sampling distribution of x.
​(b) What is P (x > 79.7)?
(c) What is P (× < 75.75)?
(d) What is P (76.95 < x < 80)?

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.
