Answer:
a
Step-by-step explanation:
Given
a - + a
Collect the terms by adding their coefficients, that is
1 - +
= - + = + = =
Thus
a - + a = a
Perimeter of a square formula: 4s, where s is one side.
perimeter = 60
4s=60
s=15
One side is 15 centimeters
the radius is half of a side

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
