Answer:
89 rooms should be set for early book customer
Step-by-step explanation:
According to the given data we have the following:
OVERAGE(CO) = 200
SHORTAGE(CS) = 500
In order to calculate how many rooms should be set for early book customer we would have to use the following formula:
OPTIMAL BOOKING = MEAN + (Z * STDEV)
MEAN = 75
STDEV = 25
SERVICE LEVEL= CS / (CS + CO) = 500 / (500 + 200) = 0.7143
Z VALUE FOR 0.7143 = 0.57
OPTIMAL BOOKING = 75 + (0.57 * 25) = 89
89 rooms should be set for early book customer
Step-by-step explanation:
Initially, there's only 1 letter.
Tania sends the letter to 4 friends.
Each friend sends a letter to 4 more friends (4 × 4 = 16).
Each of those friends sends to 4 more friends (16 × 4 = 64).
The pattern is 1, 4, 16, 64, etc.
This is a geometric sequence. The first term is 1 and each term is 4 times the previous term.
a₁ = 1
aₙ = 4 aₙ₋₁
The explicit formula is:
aₙ = 1 (4)ⁿ⁻¹
In the form
... y = a(x - h)2 + v
the vertex coordinates are (h, v). These are given in your problem statement as (2, -2).
h = 2
v = -2
(-2.3, 4.7) & (-1.5, 6.2)
X1. Y1. X2. Y2
M= <u> Y2 - Y1 </u> = <u>6.2 - 4.7 </u>
X2 - X1 -1.5 - (-2.3)
M= <u>6.2 - 4.7 </u> = <u>10.7</u> = 13.375 = 13.4
<u> </u>-1.5 + 2.3 0.8
