Answer:
- 8° per hour
Step-by-step explanation:
Given that:
Station A = - 6°
Station B = 2°
Rate of temperature change = x° / hour ; which is the same at both stations
Temperature at station A 3 hours after the recording is the same as the temperature in station B 4 hours after the recording ;
Temperature change in Station A:
-6 + 3x
Temperature change in station B:
2 + 4x
Temperature change in A = temperature change in B
-6 + 3x = 2 + 4x
Collect like terms
3x - 4x = 2 + 6
- x = 8
x = - 8
Hence, the rate of temperature change x in both stations is - 8° per hour

Answer:
Probability = 0.35
Step-by-step explanation:
Given :-
- Probability (Highway A Icy) = 0.1
- Probability (Highway B Icy) = 0.15
- Probability (Highway C icy) = 0.15
So :-
- Probability (Highway A not icy) = 1 - 0.1 = 0.9
- Probability (Highway B not icy) = 1 - 0.15 = 0.85
- Probability (Highway C not icy) = 1 - 0.15 = 0.85
Probability of person not getting to work timely
= Probability [Even one of the highway A, B or C is icy]
= 1 - Probability [None of Highway A, B, C is icy]
Since these are independent events, So :-
= Prob. [Highway A not icy & Highway B not icy & Highway C not icy]
= 1 - ( 0.9 x 0.85 x 0.85)
= 1 - 0.65
= 0.35
