The probability that one cubic meter of discharge contains at least 8 organisms is 0.7798
Answer:
- Center = (3, 0)
- Radius = 3
- Graph = see below
Concept:
Here, we need to know the idea of the circle equation.
Circle equation: (x - h)² + (y - k)² = r²
(h, k) = center
r = radius
x = variable
y = variable
Solve:
<u>Given expression </u>
(x - 3)² + y² = 9
<u>Find the point of the center</u>
(h, k) = 
<u>Find the length of the radius</u>
r² = 9
Hope this helps!! :)

Hey! since it’s a 5 sided shape it’s area will be 540° so you add up 108+100+90+120=418
the final angle is 122*
then since angles on a straight line is 180° you minus 122 from 180 and x= 58°
