The length of time (in months after maintenance) until failure of a bank’s surveillance television equipment has a weibull distribution with α = 2 and β = 80 months. If the bank wants the probability of a breakdown before the next scheduled maintenance to be 0.02, how frequently should the equipment receive periodic maintenance?

There should be a periodic maintanance for every 1.27months

Step-by-step explanation:

The step by step calculation explaining how frequent the equipment should receive periodic maintenance (Which are the activities carried out on equipment based on a stipulated time interval for the purpose of maintaining a smooth operation of a machine or equipment or on other asset.) can be seen in the attached image below.

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
