Mrs. Campbell is a librarian at Eastside Library. In examining a random sample of the library's book collection, she found the following. 969 books had no damage.
142 books had minor damage, and
29 books had major damage.
Based on this sample, how many of the 92.500 books in the collection should Mrs. Campbell expect to have no damage? Round your answer to the nearest
whole number. Do not round any intermediate calculations.

a) what number, when added to negative four, is equal to negative five?

step-by-step explanation:

where is the rest of the

step-by-step explanation:

introduction, methodology, results, discussion

step-by-step explanation:

an observational study is one which consists of actual observation to record data and then analyse the data.

there are a number of factors that should be analyzed before starting an observational study.

the main four factors are:

i) introduction:   this should be analysed to check whether the purpose of the study is correctly established and the data recorded are appropriate for the study

methodology:   the method of collecting the data, such as whether randomly selected, and whether sample size matches with the population to be studied, whether questions asked are easy to answer by common men, etc.

results: then results such as summary of data with comments should be studied thoroughly

discussion:   the last is the discussion, this can be either by management people or persons who are all interested , etc.

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)
