The green bar is 25% longer than the total length of the blue bricks

Step-by-step explanation:

2 blue bars = 1 red bar

3 blue bars = 1 yellow bar

4 blue bars = 1 maroon bar

5 blue bars = 1 green bar

The green is is 2 1/2 times longer than the red.  That eliminates choice C

We have 4 blue bars total

The red bar is 1/2 of the total length of the blue bars

That is not 3/4 so we can eliminate  choice A

We have 4 blue bricks.  If we add one more brick that would give us a green bar

1brick out of the 4 bricks we have is 1/4 = 25%

Choice B

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.

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.
