1) During busy times, 60 potential customers per hour arrive at the booth (assume a Poisson distribution). A booth worker takes 3.75 minutes, on average, to meet the information needs of a potential customer (assume an exponential distribution). How many booth workers are required for the average potential customer to spend no more than 5 minutes waiting and being served

Booth workers required = 4

Step-by-step explanation:

As given ,

Arrival rate = λ = 60 customers per hour

Time taken = 3.75 minutes

∴ we get

Average service rate = μ = = 16 customers per hour

Now,

Minimum numbers of booth workers required = = 3.75

As workers can not be in fraction

∴ Minimum number of booth workers required = 4

answer:

what is your question that you ask

step-by-step explanation:

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
