Answer:
5/20 or 25% probability of winning $1,000,000
Step-by-step explanation:
How many numbered balls do they need to win?
5
How many balls are there?
20
Therefor your answer is (balls need to win/number of balls).
Given two points: (x₁,y₁) and (x₂,y₂) the slope "m" will be:
m=(y₁-y₂) / (x₁-x₂) or m=(y₂-y₁) / (x₂-x₁)
In this case:
(4.5 , 13.5)
(-3.5 , -9)
m=(-9-13.5) / (-3.5-4.5)=-22.5 / -8=2.8125
Answer: the slope will be m=2.8125.
