The number of calories consumed by customers at the chinese buffet is normally distributed with mean 2689 and standard deviation 560. one randomly selected customer is observed to see how many calories x that customer consumes. round all answers to 4 decimal places where possible. what is the distribution of x?

Step-by-step explanation:

Let X be a random variable that represents the number of calories consumed.

Given : The number of calories consumed by customers at the Chinese buffet is normally distributed with mean 2689 and standard deviation 560.

i.e. Population mean :

Population standard deviation: .

We can say X follows normal distribution and  

So , the distribution of X :

i.e.

54

step-by-step explanation:

6x9

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
