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:
Finally, the probability that in a sample of 10 customers, at least 7 will order a nonalcoholic beverage is equal to 0.1886
Answer:
yes it does. good job on your A.
Step-by-step explanation:
The property of real numbers illustrated by the equation 16(3t+4v)=48t+ 64v.
Therefore, the answer is: Distributive property.
As you can see, you have the equation 16(3t+4v), and when you apply the Distributive property, you obtain:
16(3t+4v)
(16)(3t)+(16)(4v)
48t+64v
I believe the answer is A "If a triangle is equilateral, then it has three congruent angles". Hope this helps!
Answer:
Let C be the position of a person in a helicopter. A,B be two objects lying opposite to each other on either bank of a river.
Let AD=x,BD=y
In ΔACD,

⇒x=130(1.732)=1212.4
∴ the width of the river =x+y
=1212.4+130
=1342.4m
