Answer:
4/5
Step-by-step explanation:
Given that:
Number of options = a, b, c, d, e
Number of correct answer choice = 1
Therefore, number of wrong answers = 4
Recall :
Probability = (number required outcome / number of total possible outcomes)
P(wrong answer) :
Number of Required outcome = number of wrong answer choices = 4
Total answers = 5
Hence,
P(wrong answer) = 4 / 5 = 0.8
Answer:x= 7
Step-by-step explanation:
I don’t feel like explaining
I think its
x² - 2x + y² + 6y - 6 = 0
x² - 2x + y² + 6y = 6
(x² - 2x + 1) + (y² + 6y + 9) = 6 + 1 + 9
(x - 1)² + (y + 3)² = 16
center: (h, k) = (x, y) = (1, -3)
radius: 4
Answer:
Step-by-step explanation:
KL is tangent to the circle, so angle JKL = 90°.
Pythagorean Theorem:
r² + 24² = (r+16)²
r² + 576 = r² + 32r + 256
32r = 320
r = 10 units
