Answer:
The difference between the vehicles is 0,009 gallons per mile.
Step-by-step explanation:
To know the difference between the vehicles in gallons per mile we need to obtain this information for each car:
-Sam´s van
   Gallons per mile: 9 gallons/208.8 miles
   Gallons per mile: 0.0431 
-Hasan´s small car:
  Gallons per mile: 8 gallons/234.4 miles
  Gallons per mile: 0.0341
The difference between the vehicles is:
0.0431-0.0341= 0,009 gallons per mile
 
        
                    
             
        
        
        
Y = -1.33 * x - 3
y = -1.33 -3 *x
y = -4.33 *x

Answer: 0.01145
Step-by-step explanation:
We use Binomial distribution , where the probability of getting x successes in n trial is given by :-
 , p = probability of getting each success in each trial.
 , p = probability of getting each success in each trial.
As per given 
The proportion that a car with a certain protection system will be recovered= p=0.87
n= 8
Let x be the number of cars will be recovered.
Then, the probability that 4 of 8 stolen cars will be recovered:


Hence, the required probability is 0.01145.
 
        
             
        
        
        
Answer:
See below in bold.
Step-by-step explanation:
The triangular piece of cloth is a right triangle because 41^2 = 40^2 + 9^2 (By the Pythagoras theorem).
So the area of one piece = 1/2 * 9 * 40  cm^2.
The total amount of cloth  required for one umbrella = 10 * 1/2 * 9 * 40
= 1800 cm^2.
The total cost =  1800 * 0.25 =  Rs 450.
