Perimeter is adding all the outside sides together 1. 7+7+5 14+5= 19 m 3. The dashes mean that the sides are equal so each side is 5 5+5+5+5 10+10= 20cm Last question. The sides are 5,3,?,2,1,3,2,? Look at the top add 5+2 this will give you the length of the whole side this will let you figure out the bottom missing side 5+2=7 the bottom whole peice will be 7 also so to find the missing peice you will subtract 7-1 the missing piece measure is 6
5,3,7,2,1,3,2,?
Do the same to the right side add 3+2 This will give you the total length of the left and right side (5) Now subtract 3 from it to find the missing peice 5-3=2 5,3,6,2,1,3,2,2 Now you have all the lengths of the sides Add them together 5+3+6+2+1+3+2+2 8+6+3+3+4 14+6+4 20+4= 24m *don't forget to write down in what unit it is measured in!!* Hope I explained it clearly
It is clinical trial because in this study design a treatment is given to the individuals andthen we observe this treatment. In this experiment, we are studying the effects by giving 500 mg of Vitamin and Placebo to the soldiers.
It is not a cross-sectional study because this type of study is used to analyze characteristic of the population depending upon data but this study is not used for disease.
It is also not a case-control study as well as prospective cohort study because case-control study is used to observe the new cases of a disease while prospective cohort study is used for determining risks or exposure factors of a disease.
It is not a community trial as in which a community is under observation like a city or a country and it is also not a historical prospective cohort study because in this study type, we observe the cohorts (similar objects) with the different qualities. They are studied on the basis of these qualities.
