When generating a calibration curve, what information typically goes on the x and y axes, ie, which axis is the dependent variable, and which axis is the independent variable?

Step-by-step explanation:

A is a general method for determining concentration of a substance in an unknown sample by comparing it to standard samples of known concentrations.

X- axis is the independent variable. It is chosen by the experimenter. It is independent because the experimenter choose at what concentration levels to take measurements.

Y-axis is the dependent variable. Absorbance rates will depend on the concentration levels set by the experimenter.

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq
