Answer: 200 randomly selected students in the school
Step-by-step explanation:
Population refers to a total set of observation that can be made, a whole group or entire set which we desire to observe or test. While sample refers to a smaller manageble version of a population on which testing could be done. Samples should be selected randomly and should contain characteristics of the larger group.
In the case above the sample is the 200 randomly selected students in the school because because that is the selected set of people from which testing was done to draw conclusions about the whole population.
X is your teams score
Y is your opponents score
X-19= Y
X+Y= 49
X=34
34-19= 15
Y=15
34+15= 49
Well, in order to prove the Pythagorean theorem, every triangle you are using has to have one right angle (90-degree angle), and the side opposite to it will be called the hypothenuse. The remaining two triangles will be acute angles (<90 degrees), and the sides opposite to them are called sides/catheti.
