Answer:
Domain:
Range:
Step-by-step explanation:
Given
Required
Determine the domain and the range
Solving for domain:
From the question, we understand that t represent years.
Because years can't be negative;
Then, we can conclude that the domain, t is:
Solving for Range:
We solved domain to be
This implies that the minimum value of t is and the maximum is infinity
Substitute 0 for t in
Hence;
The range is
Answer:
5 / 8
Step-by-step explanation:
Given :
Red devices = 5
Blue devices = 10
P(red failure) = 1/2
P(blue failure) = 1/4
Probability of failure if we pick a device equals ; P(red failure) or P(bue failure) =P(RuB)
P(RuB) = P(red failure) + P(Blue failure) - P(RnB)
P(RnB)
P(P(red failure) * P(Blue failure)
1 / 2 * 1/ 4
= 1/ 8
P(RuB) = P(red failure) + P(Blue failure) - P(RnB)
P(RuB) = 1/2 + 1/4 - 1/8
P(RuB) = 3/4 - 1/8 = (6 - 1) / 8 = 5/8
Hence, probability of failure is 5/8
