If each customer takes 3 minutes to check out, what is the probability that it will take more than 9 minutes for all the custome

AnnyKZ [126]

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:

P(X = 0) = 0.2;

P(X = 1) = 0.15;

P(X = 2) = 0.30;

P(X = 3) = 0.20;

P(X = 4) = 0.10;

P(X = 5) = 0.05;

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.

You need a ladder that will reach up to 25 foot tall house when placed 10 feet away from the house. How tall does the ladder nee

lions [1.4K]

This creates a right triangle. One leg of the triangle is 25 feet and the other is 10 feet. To find the length of the ladder, we must use Pythagorean theorem.

a = 25

b = 10

c = ?

(25)^2 + (10)^2 = c^2. Square all the terms to the left of the equation and add them together.

725 = c^2. Take the square root of each side.

c = 26.93 feet.

The ladder needs to be 26.93 feet tall.
