t the Fidelity Credit Union, a mean of 5.8 customers arrive hourly at the drive-through window. What is the probability that, in

zhuklara [117]

Answer:

0.5217

Step-by-step explanation:

Given that:

mean $\mu$ = 5.8

Using Poisson Probability formula:

$P(X=x) = \frac{ (e^{- \mu} * {\mu^x) }}{x!}$

$P(X>5.8)=1-P(X \leq5)$

$= 1-[P(X=0)+P(X=1)+P(X=2)+P(X=3)+P(X=4)+P(X=5)]$

$= 1 -[\frac{(e^{-5.8}*5.8^0) }{ 0! } + \frac{(e^{-5.8}*5.8^1) }{ 1! } +\frac{(e^{-5.8}*5.8^2) }{ 2! } +\frac{(e^{-5.8}*5.8^3) }{ 3! } +\frac{(e^{-5.8}*5.8^4) }{ 4! } +\frac{(e^{-5.8}*5.8^5) }{ 5! } ]$

$=1-(0.003+0.0176+0.0509+0.0985+0.1428+0.1656)$

$=1-0.4783$

$=0.5217$

∴ the probability that, in any hour, more than 5 customers will arrive =0.5217

The product of nine and a number is added to six the result is 24 what is the number

Andru [333]

Hello!

We can make an equation based on what we know

The product of 9 and a number is

9 * x

Added to six

9 * x + 6

Gives the result of 24

9 * x + 6 = 24

Now you solve it algebraically

Subtract 6 from both sides

9 * x = 18

Divide both sides by 9

x = 2

The answer is 2

Hope this helps!

A recipe calls for 9 tablespoons of milk for every 21 cups of flour. If the chef puts in 168 cups of flour, how many tablespoons

Tamiku [17]

Since you use 9 tablespoons per 21 cups, you need to first divide 168 by 21 and get 8. Then you will take 8 times 9 and get 72 tablespoons of milk.
