The lifetime of a lightbulb in a certain application is normally distributed with mean μ = 1500 hours and standard deviation σ = 200 hours. NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. What is the probability that a lightbulb will last more than 1800 hours?

0.000647588

Step-by-step explanation:

The normal probability function formula is:

To find the probability that a lightbulb will last more than 1800 hours, we can plug in x = 1800, μ = 1500, and σ = 200

So the probability that a lightbulb will last more than 1800 hours is 0.000647588

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this

the answer is 18 units because there are 18 small cubes inside the rectangle

hope this and p.s i am also in k12
