3.6 (a) the proportion uptime of a certain piece of production equipment is 97.5%. when a breakdown occurs, the mean time to repair is 45 min. determine the mean time between failures of this equipment.

1755 minutes

Step-by-step explanation:

To determine the mean time between failures in the equipment you need to calculate the time in which this equipment is functional. You know that the 97.5% of the time the equipment is working, so the other 2.5% the equipment is failing; this means that 45 min is 2.5%. With a rule of three you can calculate the time of working (97.5*45)/(2.5) = 1755 minutes. So between failure the equipment can work 1755 minutes.

hello :

70y^8 + 30y^6 = 2 ( 35 y^8 + 15y^6)

the lenght is : 35 y^8

the width is : 15y^6

50-38=12
