Answer:
amplitude = 3
Step-by-step explanation:
the amplitude is the vertical distance from center of the wave to the crest or the trough
7*3/10 = 2.1
1*3/4 = 0.75
2.1 + 0.75 = 2.85
hope this helps :)
The number of failures in 3000 hours with an MTBF of 6 hours is 500. When the MTBF is 8 hours, the number of failures drops to 375, a savings of the cost of 125 failures, or $25,000.
