1. It's asking if the hourly pay seems linear or nonlinear. Which is practically you just giving one or the other.
2. It's asking where the number cluster close together. Which is from 4-6
Those are the only 2 I see difficult to understand
Answer:
The answer is 350 points
Step-by-step explanation:
The Area of a circle is πr∧2
The problem states that in the attempts, you never hit the outermost ring in the 10 attempts so we need the area of the 1cm and 2cm circles
Area of the 1st circle; π X 1∧2 = π
Area of the Second circle; π X 2∧2 = 4π
We also need the area which is the difference between the area of the 1cm and 2cm circle
4π - π = π
Points 50 = π/4π = 1/4
points 30 = 3π/4π = 3/4
For one attempt,
E(x) = 50 x 1/4 + 30 x 3/4
= 12.25 + 22.5
= 34.75
This is approximately 35
Therefor, 10 individual attempts will be 10 x 35 = 350
X =(-5-√97)/6=-2.475 or x =(-5+√97<span>)/6= 0.808</span>
