The lifetime of a mechanical assembly in a vibration test is exponentially distributed with a mean of 500 hours. If an assembly has been on test for 500 hours without a failure, what is the probability of a failure in the next 100 hours

the aswere is the one with all 8's and the second one is with the 10,8 and 6

step-by-step explanation:

(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.

x² + 11x + 18 < 0  

[-11 ± sqrt(121 - 72)]/2 = (-11 ± 7)/2  

solution: (-9, -2)

step-by-step explanation:

i would say true? if the unit was informational and it "refreshed your understanding", then true.
