Answer:
0.5122 or 51.22%
Step-by-step explanation:
In a certain city, in June Probability of cloudy days = P(cloudy) = 0.41
Probability of cloudy and rainy = P(cloudy and rainy) = 0.21
Probability of rainy if we already know it is cloudy =
= = 0.512195122 ≈ 0.5122
Therefore, the probability that a randomly selected day in June will be rainy if it is cloudy is 0.5122 or 51.22%
Use the distance formula to find the length of the sides, then add them up to find the perimeter.
For points in the form of (x1, y1), (x2, y2).
(-1, 2), (3, 1)
(3, 1), (7, 2)
(7, 2), (-1, 2)
So the perimeter will be:
For points in the form of (x1, y1), (x2, y2).
(-1, 2), (3, 1)
(3, 1), (7, 2)
(7, 2), (-1, 2)
So the perimeter will be:
