As the manager of the Starbucks on Baltimore Avenue (route 1), you are concerned about staffing needs. You believe customer visits follow a Poisson distribution and that student customers average 18 visits to the store over a 30-days month. a. How many times do you expect a student customer to visit the store in a 5-days period?b. What is the probability a student customer visits the store four times in a 5-days period?c. What is the probability a student customer visits the store no more than two times during a 5-days period?d. What is the probability a student customer visits the store at least three times during a 5-days period? tour times in a 5-days period? 5-days period?

step-by-step explanation:

x^2 -12x + 36 + y^2 = 36

x^2 + y^2 = 12x

r^2 = 12rcos(theta)

r = 12 cos(theta)

a)(x-2)^2+(y-1)^2=9

step-by-step explanation:

18 units²

step-by-step explanation:

first let's find altitude bd using the distance formula

d = √((y₂ - y₁)² + (x₂ - x₁)²)

bd = √((0 - -3)² + (0 - 3)²)

bd = √18

given the placement of points a and c, we can denote that point d bisects segment ac.

we will call ac the base.

using the distance formula

ac = √((0 - 6)² + (-6 - 0)²)

ac = √72

knowing our base and our height, we can plug these into our triangle area formula

area = (b * h)/2

area = (√18 * √72) / 2

area = (√1296) / 2

area = 36 / 2

area = 18 units²
