Answer:
the MTTF of the transceiver is 50.17
Explanation:
Given the data in the question;
failure modes = 0.1 failure per hour
system reliability = 0.85
mission time = 5 hours
Now, we know that the reliability equation for this situation is;
R(t) = [ 1 - ( 1 - 
)³] 
so we substitute
R(5) = [ 1 - ( 1 - 
)³] 
= 0.85
[ 1 - ( 1 - 
)³] = 0.85
[ 1 - ( 0.393469 )³] = 0.85
[ 1 - 0.06091 ] = 0.85
0.9391 = 0.85
= 0.85 / 0.9391
= 0.90512
MTTF = 5 / -ln( 0.90512 )
MTTF = 50.17
Therefore, the MTTF of the transceiver is 50.17
Answer:
Both Technician A and technician B are correct.
Explanation: A transistor must have a P-N junction as that is where the positive and negative charges are connected.
A transistor also can be described as a semiconductor which acts as a switch and can be used to amplify currents. Transistors are very key and vital to electronic devices especially the mobile phones in recent times, it helps to ensure that electronic systems perform optimally.
The charges in the P-N junction is controlled by the availability of Positive and negative electrons.

Answer:
To design a pair of running shoes for women.
Explanation:
A good problem statement will led a reader from a shared context to understanding of a problem and on to a proposed solution.
The elements of a good problem statement are ;
- It should be addressing a gap in an idea
- It should be vital enough to contribute to an existing body of research
- It should offer room for further research
- It should give itself to investigation through data collection.
