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 = ![\frac{\text{[P(cloud and rainy)]}}{[P(cloud)]}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Ctext%7B%5BP%28cloud%20and%20rainy%29%5D%7D%7D%7B%5BP%28cloud%29%5D%7D)
= 
= 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%

Answer:
c: is the answer 2 (3 x + 4) (x + 2)
Step-by-step explanation:
Factor the following:
6 x^2 + 20 x + 16
Factor 2 out of 6 x^2 + 20 x + 16:
2 (3 x^2 + 10 x + 8)
Factor the quadratic 3 x^2 + 10 x + 8. The coefficient of x^2 is 3 and the constant term is 8. The product of 3 and 8 is 24. The factors of 24 which sum to 10 are 4 and 6. So 3 x^2 + 10 x + 8 = 3 x^2 + 6 x + 4 x + 8 = 2 (3 x + 4) + x (3 x + 4):
2 2 (3 x + 4) + x (3 x + 4)
Factor 3 x + 4 from 2 (3 x + 4) + x (3 x + 4):
Answer: 2 (3 x + 4) (x + 2)
The answer is B which is 1500
