Answer:
x = 7
Explanation:
8 + 4 = 2 (x − 1)
Simplify both sides of the equation
8 + 4 = 2(x − 1)
8 + 4 = (2)(x) + (2)(−1) (Distribute)
8 + 4 = 2x + −2
(8 + 4) = 2x − 2 (Combine Like Terms)
12 = 2x − 2
12 = 2x − 2
Flip the equation
2x − 2 = 12
Add 2 to both sides
2x − 2 + 2 = 12 + 2
2x = 14
Divide both sides by 2
2x / 2 = 14 / 2
x = 7
Answer:
91
Step-by-step explanation:
for a 2-digit number the tens digit (x) is 8 more than the ones digit (y) and no number is zero
=> x = y+8
x < 10
y > 0
y = 1 and x = 1 + 8 =9
the 2-digit is 91
Answer:
(a) 0.01029 (b) 4.167 customers (c) 0.4167 hours or 25 minutes (d) 0.5 hours or 30 minutes
Step-by-step explanation:
With an arrival time of 6 minutes, λ=10 clients/hour.
With a service time of 5 minutes per transaction, μ=12 transactions/hour.
(a) The probability of 3 or fewer customers arriving in one hour is
P(C<=3)=P(1)+P(2)+P(3)


(b) The average number of customers waiting at any point in time (Lq) can be calculated as

(c) The average time waiting in the system (Wq) can be calculated as

(d) The average time in the system (W), waiting and service, can be calculated as
