A company advertises that its batteries still have a 80% chance of working when they are 10 years old. You find a pack of 20 batteries in a drawer that are 10 years old, so you start to test them to see if they work. What is the probability that you start with 4 good batteries and then get a defective battery?

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.

i think the answer is c sorry if it's wrong
