The duration of a voice telephone call is an exponential random variable V with expected value E[V]=8 minutes, and the duration of data call is an exponential random variable D with expected value E[D] = d>8 minutes.

The null hypothesis is H0: a call is a voice call, while the alternative hypothesis is H1: a call is a data call.

The probability of a voice call is P[V]=0.8, while the probability of a data call is P[D]=0.2.

A binary hypothesis test measures T minutes, the duration of call. The decision is H0 if T≤t minutes. Otherwise, the decision is H1.

Write the formula for the false alarm probability as a function of t and d

$30.32

step-by-step explanation:

65.00*.12=2.80

65.00-2.80=57.20

57.20*1.06=60.632

60.632/2=30.316

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.

happy to

pls mark as brainliest.

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
