Answer:
-12x+20
Step-by-step explanation:
Subtract similar numbers:
2x - 14x = -12x
Product:
12 - 12x + 8
Group the terms that are similar:
-12x + 12 + 8
Add the numbers:
-12x + 20
Final answer:
-12x + 20
 
        
                    
             
        
        
        
Answer:
a. 8.66 minutes
Step-by-step explanation:
Since the flight times are uniformly distributed, the standard deviation can be calculated as follows:

Where '<em>b' </em>is the maximum flight time (150 minutes) and '<em>a' </em>is the minimum flight time (120 minutes):

The distribution's standard deviation is 8.66 minutes.
 
        
             
        
        
        
Answer:
  x = -6
Step-by-step explanation:
Step  1  :
Pulling out like terms :
 1.1     Pull out like factors :
   -2x - 12  =   -2 • (x + 6) 
Equation at the end of step  1  :
Step  2  :
Equations which are never true :
 2.1      Solve :    -2   =  0
This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation :
 2.2      Solve  :    x+6 = 0 
 Subtract  6  from both sides of the equation : 
                      x = -6
One solution was found :
                   x = -6

There are two costs involved:
1) the cost for lunch, which is given as a rate per student: $7.25/student
2) the cost for the trip which is $443.75 to be divided by the 25 students, so it is $443.75 / 25 = $17.75/student
Now, you can add up those two costs per student to have the total cost per student:
$7.25 + $17.75 = $25.00/student
Answer: $25.00
