Answer:
The approximate probability that 10 squared centimeters of dust contains more than 10110 particles is 0.1357
Step-by-step explanation:
For a sample of 10 sqaured centimeters of dust, the total amount of asbestos particles has a Poisson distribution with a mean of 1000/1 * 10 = 10000.
We will approximate this probability to a normal distribution. The variance is also 10000 (because it is poisson), therefore the standard deviation is √10000 = 100. Lets call X the distribution, and W its standarization, given by
We have
Where is the cummulative distribution function of a standard normal distribution. The values of
are well known and they can be found in the attached file.
We conclude that the approximate probability that 10 squared centimeters of dust contains more than 10110 particles is 0.1357.
Answer:
The value of x is 12.
Step-by-step explanation:
To make the denominators the same we can: Multiply the top and bottom of each fraction by the denominator of the other.
Cross multiply with each other.
We would first just add up the numbers without the 
in our way.
And then afterward, we wouldn't be able to add x based on the fact that it would then be viewed as multiplication, therefore your answer would then be below.
Your correct answer would then be
