Answer:
Right, Acute, Scalene.
Step-by-step explanation:
Expected number of wins=number of plays times the probability of winning
w=20(14.5/100)
w=20(0.145)
w=2.9
w≈3
So you would expect to win 3 times out of 20 attempts (rounded to the nearest whole number of wins)
55% because you add 80% and 30% which is 110% and divide that by 2.
For #11, the answer is the tall sipper thing. The formula for area in a cylinder is r squared times height. you did diameter squared, not radius squared
