Answer
The initial temperature was T = -7 degrees
Step-by-step explanation:
Let the initial temperature be T.
- The tempature was very cold
Temperarure = T
- Then it doubled
Temperature = 2T
- Then it dropped 10 degrees
Temperature = 2T - 10
- And then it increased by 40 degrees.
Temperature = 2T - 10 + 40 = 2T + 30
The tempature is now 16 degrees
Temperature = 16 degrees
2T + 30 = 16
2T = -14
T = -7 degrees

Answer:
37.6%
Step-by-step explanation:
P(A|B) = P(A and B) / P(B)
P(red | car) = P(red and car) / P(car)
P(red | car) = 0.32 / 0.85
P(red | car) = 0.376
