Answer:

Step-by-step explanation:
The variable x, that said the number of customer that will order a nonalcoholic beverage in a sample of n customers follows a binomial distribution. Because we have n identical and independent events with a probability p of success and (1-p) of fail.
So, the probability that x customers will order a nonalcoholic beverage is:

Where n is the size of the sample and p is the probability that a customer order a nonalcoholic beverage, so replacing the values, we get:

Now, the probability that at least 7 will order a nonalcoholic beverage is equal to:

Where:

So,  is equal to:
 is equal to:

Finally, the probability that in a sample of 10 customers, at least 7 will order a nonalcoholic beverage is equal to 0.1886
 
        
             
        
        
        
Answer:
rectangle = 180 
triangle = 350
the triangle has a much larger area.
350-180=170
the triangle by 17
 square inches 
 
        
             
        
        
        
This is what I got
Area= 31.83 rounded would be 32 
Radius= 3.18 rounded would be 3 
Diameter= 6.37 rounded would be 6
