Using a discrete probability distribution, it is found that there is a 0.15 = 15% probability that it will take more than 9 minutes for all the customers currently in line to check out.
<h3>What is the discrete probability distribution?</h3>
Researching the problem on the internet, it is found that the distribution for the number of customers in line at the store is given by:
Hence, since each customer takes 3 minutes to check out, the probability that it will take more than 9 minutes for all the customers currently in line to check out is the probability that there are more than 3 customers, hence:
P(X > 3) = P(X = 4) + P(X = 5) = 0.10 + 0.05 = 0.15.
0.15 = 15% probability that it will take more than 9 minutes for all the customers currently in line to check out.

Answer:
h = 
Step-by-step explanation:
Formula for the area of a trapezoid is,
Area (A) = 
Here b and c are the bases and 'h' is the height of the trapezoid.
2A = ![2[\frac{1}{2}(b+c)h]](https://tex.z-dn.net/?f=2%5B%5Cfrac%7B1%7D%7B2%7D%28b%2Bc%29h%5D)
2A = (b + c)h
Therefore, formula for the height of the trapezoid will be,
h =
Answer: D
Step-by-step explanation:
You have -5 1/2 to find the complete opposite all you have to do is take away the negative sign and find the number on the number line.
Good luck !
Answer:
105/9
Step-by-step explanation:
180 - 132 = 48 degrees
180 - 48 - 45
= 180 - 93
= 87 degrees
<2 = 180 - 87
= 93 degrees
=> 9x - 12 = 93
=> 9x = 105
=> x = 105/9
