The point-slope form of the equation for a line can be used.
.. y = m(x -h) +k . . . . . for slope m through point (h, k)
.. y = 2(x +1) +4
This can be simplified to slope-intercept form.
.. y = 2x +6
Answer:
a. 0.45 customers
b. 0.0145 hours
c. 1.05 customers
Step-by-step explanation:
Missing word "A vending machine dispenses hot chocolate or coffee. service time is 30 seconds per cup and is constant. customers arrive at a mean rate of 72 per hour, and this rate is Poisson-distributed."
λ = 72 customers per hours
μ = 120 customers per hours
a. Lq = λ²/ 2μ(μ-λ)
Lq = 72² / 2(120)(120-72)
Lq = 9/20
Lq = 0.45 customers
b. Ws = Wq + 1/μ = Lq/λ + 1/μ
Ws = 9/20 customers/72 customers + 1/120 customers
Ws = 0.0145 hours
c. Ls = Lq + r
Ls = 9/20 + 72/120
Ls = 1.05 customers
Answer:
Step-by-step explanation:
Let X be the amount of money that Laurie has to spend.
Let Y be the amount of money that Laurie's sister has to spend.
Let C be the cost of a box of chocolates.
The following represents how much money Laurie and her sister have after buying the box of chocolates:
X + Y - C
This result is the amount of money that Laurie and her sister have left to buy on flowers.
Let F be the amount of money that Laurie and her sister spend on flowers.
We know that the above result must be greater than or equal to the amount that Laurie and her sister spend on flowers; otherwise they will be spending more than they have.
The following equation then represents how much Laurie and her sister have left to spend on flowers:
X + Y - C F
Plugging in the values for the above letters will give you your answer.
