The resistance, R, to electricity of a cylindrical-shaped wire is given by the equation R=pL/(pi)d^2 where p represents the resi

SashulF [63]

Answer:

The resistance approaches infinity

Step-by-step explanation:

We are given

The resistance, R, to electricity of a cylindrical-shaped wire is given by the equation

$R=\frac{\rho L}{\pi (d)^2}$

where

p represents the resistivity of the wire’s material

L represents the length of the wire

d represents the diameter of the wire

now,

d approaches to 0

so, we can plug d=0 and find R

$R=\frac{\rho L}{\pi (0)^2}$

$R=\frac{\rho L}{0}$

$R=\infty$

So,

The resistance approaches infinity

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)
