Answer:
(x - 4)² + (y + 9)² = 5²
Step-by-step explanation:
The standard form equation is
(x - h)² + (y - k)² = r²
(h, k) is the center
r is the radius
----------------------------
Given (h, k) = (4, -9) and r = 5
(x - 4)² + (y + 9)² = 5²

<span>Answer: the last option: 10%
Explanation:
1) Plan B: Treatment with Drug Y—if not effective, treatment with Drug X
2) The two drugs work independent of each other => joint probability equals the product of the individual probabilities.
3) probability of drug y is not effective = 1 - probability of being effective = 1 - 0.6 = 0.4
4) probability of drug x is not effective = 1 - probability of being effective = 1 - 0.75 = 0.25
5) Joint probability of being not effective = 0.4 × 0.25 = 0.10
6) 0.10 = 10%
Therefore the answer is 10%
