Suppose customers arrive randomly one at a time (independant of each other) to a drive-through at a fast food restaurant at a rate of 1 every 10 minutes on the average. Suppose an employee is working a 4 hour shift there. Let X be the number of customers that vise the drive-through during their shift. a. What is the distribution of X? Give the name of the distribution and the appropriate parameters. b. Whnt is the mean and variance of this distribution? Give your answer as a number, but include the formulas (or logic) used. Note be very careful with mixing time units! c. What is the probability they have no customers during their shift?d. What is the probability that they have between 15 and 25 customers during their shift?

well we know there are 4 clubs in 52 cards so it’s replaced so it should be 3/51

step-by-step explanation:

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11 -1> 1 -1+ a

-12 > a

step-by-step explanation:

let's assume

number of candles set =x

price of of x candles =p(x)

we are given

a candle maker prices one set of scented candles at $10 and sells an average of 200 sets each week

so, we get point as (200,10)

he finds that when he reduces the price by $1, he then sells 50 more candle sets each week

so, we can find slope

now, we can use point slope form of line

now, we can plug values

we can use point

and find b

now, we can plug it back

and we get

now, we can find revenue

we know that

revenue = price*quantity

so, we get

b.
