Solve the following for a: 3/4 + 1/6 = a

11/12

When you did exercise one and calculated slope, what number should that slope have been closest to?

3

In our equation relating circumference and diameter (Circumference = pi x Diameter), which variable is the independent variable?

Diameter

In the next lab, we will be introduced to the ideal gas law, PV=nRT. If we are dealing with a sealed container, its volume (V) does not change, nor does the number of gas particles in it (n). This makes the only variables pressure (P) and temperature (T), the letter R represents a known constant. This means that as we change the temperature, the pressure should change somehow. If P is the dependent variable, we can use algebra to rearrange the equation so it is alone on the left side of the equal sign (Just divide through by V): P=(nR/V)(T). In this new equation, what is the independent variable?

Suppose a graduate student is doing research and decides to ignore evidence that disagrees with their hypothesis because they really like their hypothesis. Which element of science is the student violating?
