Answer:

t=8

Step-by-step explanation:

Subtract 12t from both sides

(12t-12t) + 16 = (13t-12t) + 24

16 = 1t (or just t) + 24

Then subtract 16 from both sides, and bring "t" over the equals sign making it a negative integer.

-t = 8

t = 8

The time to failure (in hours) for a laser in a cytometry machine is modeled by an exponential distribution with . Round the ans

wariber [46]

Answer:

a)e^-(λ20891)

b)1-e^-(λ30598)

c)1-e^-(λ30598)-e^-(λ20891)

Step-by-step explanation:

The probability density function (pdf) of an exponential distribution is

f(x,λ)=λe^-(λx) for x>0, and 0 for x<0

The cumulative distribution function is given by

F(x,λ)=1-e^-(λx) for x>0, and 0 for x<0

P(X≥20891)=1-P(X≤20891)=1-F(20891,λ)=e^-(λ20891)

P(X≤30598)=F(30598,λ)=1-e^-(λ30598)

P(20891≤X≤30598)=F(30598,λ)-(20891,λ)=1-e^-(λ30598)-e^-(λ20891)
