Answer:
Step-by-step explanation:
a=0 and b=20 in the uniform density function
∴ the mean μ===10 and
the variance ==.
The standard deviation is the square root of the variance, so
Having determined the mean and standard deviation of the uniform distribution, we can conclude that follows a normal distribution with and .
The normal probability distribution is:
So, substituting and
Having approximated sum , we move on to the standardized sum , which is the same as only with μ=0 and σ=1. This means the probability distribution is the standard normal distribution, which is:
Answer:
x = -2
y = 7
Step-by-step explanation:
x = 12 - 2y
7(12 - 2y) + 4y = 14
84 - 14y + 4y = 14
84 - 10y = 14
10y = 70
y = 7
x = 12 - 2 x 7
x = 12 - 14
x = -2
The Dewey Decimal Classification System is a method used
to calssify books in the library. It was named after Melvil Dewey who developed
it in 1876. The system uses numbers to organize the subjects of each nonfiction
books and are divided into 10 main subject groups called categories. Each category
is presented by a figure starting from 000 to 999. Each number presents a
special topic. Books with the same number are placed in alphabetical order by
the last name of the author. The first digit of a three digit number signifies
the main class. Suppose you have 500, the 5 in signifies natural sciences and
mathematics. The second digit signifies the division and the last digit signifies
the sections.
