Because infedecimals. Basically 1 -.99999.... Is a number so close to zero it is impossible to define. If this were infanct the case however and a number existed that was not 0 and not 0 it would wreck mathematics so infedecimals exist only theoretically. So .999... Is equal to 1 practically but not theoretically.
On all sides of a triangle it’s about 7 inches

Answer:
The simplified value of the exponential expression is:
Step-by-step explanation:
Assuming the exponential expression
Therefore, the simplified value of the exponential expression is:
Answer:
19.24 weeks
Step-by-step explanation:
Given that;
Mean, m = 18
Standard deviation, s = 3
Break down cost = 2000
Preventive maintenance cost = 1400
The optimal preventive maintenance level is Given by :
Mean + service level * standard deviation
Service level = preventive maintenance cost / (breakdown cost + preventive maintenance cost)
Hence,
Service level = 1400/(1400+2000) = 1400 / 3400
Service level = 0.4117647
Optimal preventive maintenance level :
18 + (0.4117647 * 3)
18 + 1.2352941
= 19.235
= 19.24 weeks
