Answer:
C. The system is functioning correctly and providing accurate information
Explanation:
Reliability refers to the ability of a system or a machine to perform its intended function with minimal or nil breakdown. Consistency and validity of data from the performance of a system or a piece of equipment indicate its reliability. It is the possibility of failure-free operation of a system.
Reliability will, therefore, ensure a system is performing its function with minimal interruptions resulting from failures. It guarantees consistency in the results from operations. With reliability, production happens when it is needed.
Answer:
b. False
Explanation:
It is the opposite, when several systems operate in parallel, total system capacity is the lowest value of the individual system capacities.
For e.g., sectors A, B and C operate in parallel. Sector A can handle 100 units per hour, sector B can handle 150 units per hour and sector C can handle 75 units per hour. The system's capacity is 75 units per hour. If you want to operate at 100 units per hour, a queue will in sector C.
Let
x = minutes used for jogging
y = minutes used for handball
z = minutes used for cycling
Th total time spent is 1 hour (60 minutes), therefore
x + y + z = 60
Because Mike jogs as long as he cycles, therefore
x = z
Therefore
2x + y = 60
or
y = 60 - 2x (1)
Jogging consumes 10 calories/min, handball consumes 9 calories/min and cycling consumes 12 calories/min.
The calories consumed in 60 minutes is 580, therefore
10 x + 9y + 12z = 580
Because x = z,
22x + 9y = 580 (2)
Substitute (1) into (2).
22x + 9(60 - 2x) = 580
22x + 540 - 18x = 580
4x = 40
x = 10
y = 60 - 2x = 40
z = x = 10
Answer:
10 minutes of jogging
40 minutes of handball
10 minutes of cycling.
