Answer: 15
Step-by-step explanation:
If you draw out the polygon with the vertices given, you'll see a trapezoid with one base of 6 units long, one base of 4 units long and a height of 4 units.
Using the formula for area of a trapezoid : h(b1 + b2)/2
h is the height, b is the base
After inputting your numbers into the formula you get, 4(4+6)/2
Which comes out to be 4(10)/2 or 40/2
Which will get you the answer, 20.

4(5)+4(2)=4(5+2)
=4(7)
=28
8(4)-8(2)=8(4-2)
=8(2)
=16

Answer:
- 36.00%
- 99.9976%
Step-by-step explanation:
Two mutually exclusive events that cover all possible events have a combined probability of 1.
1. If there is no middle ground—you either pass math or you don't—then the probability of not passing math this semester is 100% - 64% = 36%.

2. If there is no middle ground—you either win the lottery or you don't—then the probability of not winning the lottery is 100% - 0.0024% = 99.9976%.
