Alice walks into a post office with 2 clerks. both clerks are in the midst of serving
customers, but alice is next in line. the clerk on the left takes an expo(λ1) time to
serve a customer, and the clerk on the right takes an expo(λ2) time to serve a customer. let t be the amount of time alice has to wait until it is her turn.
(a) write down expressions for the mean and variance of t, in terms of double integrals
(which you do not need to evaluate).
(b) find the distribution, mean, and variance of t, without using calculus.

Examine the paragraph proof. which theorem does it offer proof for? prove jnm – nmi according to the given information in the image. jk | hi while jnm and lnk are vertical angles. jnm and lnk are congruent by the vertical angles theorem. because lnk and nmi are corresponding angles, they are congruent according to the corresponding angles theorem. finally, jnm is congruent to nmi by the transitive property of equality alternate interior angles theorem gorresponding angle theorem vertical angle theorem o same side interior angles theorem
