The area of a blackboard is 1 1/3 square yards posters area is 8/9 square yards find the unit rate and explain in words with unit rate means in the context of this problem is in more than one unit that can be calculated how do you know

Unit rate of area of blackboard to area of poster =

Unit rate of area of Poster to area of blackboard = =              

Step-by-step explanation:

Rates help us to evaluate or compare two different quantities.

Unit rate help us to compare or know that how the  units of the quantity 1 is related to units of quantity 2.

We are given that:

Area of Blackboard =

Area of Poster =

Unit rate of area of blackboard to area of poster: It mean that how does unit area of blackboard is related to or corresponds to area of poster

=

Thus, 1 unit area of blackboard corresponds to

Unit rate of area of Poster to area of blackboard: It mean that how does unit area of poster is related to or corresponds to area of blackboard.

=

Thus, 1 unit area of Poster corresponds to

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.

point a is the center of the circle that passes through points e, f, and g and the center of the circle that passes through points x, y, and z.
