What does independent variable and dependent variable mean?
The independent variable is the variable that the scientist controls and can change in an experiment. There should be only one independent variable in an experiment; otherwise the cause-and-effect of the independent variable cannot be determined.The dependent variable is the variable that is affected by the independent variable.EXAMPLE:Students of the same age have been given different sleeping hours (the independent variable)The next day they are tested for their performance (the dependent variable).(Having students the same age is a third type of variable, called the constant variable or the control variable. It is deliberately kept the same to reduce any effects on the outcome.)

What are the identifying features of an isosceles triangle?
An isosceles triangle has two equal sides (and a third that is a different measure). It can also be identified by the fact that it has two equal angles and the third is different. The above also mean that two of the three altitudes, medians, etc are equal while the third is different. If the third measure is not different the triangle is equilateral.
Is the problem y equals one third x direct variation?
yes
There are 33 students in the band 6 more fifth grade students than third grade students but an equal number of third and fourth grade students how many third grade students are in the band?
This is a single-equation algebra problem, and can be stated using the variable T to stand for the number of Third Grade students (our answer).The equation is Fifth Grade + Fourth Grade + Third Grade = 33 total members.In terms of T, this is (T+6) + (T) + (T) = 33Which reduces to 3T + 6 = 33 and 3T = 27 and T = 9.There are 9 third-grade students, 9 fourth-grade students, and 15 fifth-grade students = 33.
