A recent survey by the American automobile association showed that a family of two adults and two children on vacation in the United States will pay an average of 247 per day for food and lodging with a standard deviation of 60 per day. Assuming the data are normally distributed, if the family had a z-score of 1.5, what was their daily expense for food and lodging

step-by-step explanation:

∆abc has the points a(1, 7), b(-2, 2), and c(4, 2) as its vertices. formed with the point d(1, 2) as its third vertex, then ∆abd is triangle.

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.
