Answer:
Step-by-step explanation:
because y² + 4y + 5 = (y+2)² + 1 > 0, ∀ y ∈ R
=> y² + 4y + 5 = 0 is unreasonable
=> no solutions
The actual size of the room is 8 feet by 20 feet.
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

Answer:
A. -2/3x - 2/5
Step-by-step explanation:
-2 x 1/3x = -2/3x
-2 x 1/5 = 2/5
-2/3x - 2/5
