Great Aunt Lulu has 4056 buttons in her button box. She is going to give 0.2 of her collection to Marcus, 0.5 to Cody, and 0.3 to Dillion. How many buttons does each kid get? Will give brainlist

811 buttons for Marcus, 2,028 buttons for Cody, and 1217 buttons for Dillon

Step-by-step explanation:

We can find how much Lulu gives to each person by multiplying 4,056 by each child decimal.  

For further reference, I'll represent the amount she gives to Marcus with an M, the amount she gives to Cody with a C, and the amount she gives to Dillon with a D.

M = 4,056 * 0.2 = 811.2 = 811 (We must round, as you cannot have parts of a button.

C = 4,056 * 0.5 = 2,028

D = 4,056 * 0.3 = 1216.8 = 1,217

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.
