What is the difference between curve fitting and regression?
curve fitting is a very difficult and time wasting method while regrresion is more to use as compare to curve fitting
How do you determine a slope from a graph?
Slope = (vertical change)/(horizontal change), commonly referred to as rise/run. If the graph is a straight line, then you can count squares or measure how much change in vertical, over a specified change in horizontal. If it is a curve, then you need to have a tangent line (a line that touches the curve at a specific point and has the same slope as the line), then you can determine the slope of that line using the method described, above.
What assumptions determine the production possibilities curve?
Assumptions to determine the PPC is:only 2 goods will be illustratedthe amount of resources is fixedstate of technology is constant
What are the two parameters that are necessary to determine probabilities for a particular normal distribution curve?
Mean and Standard Deviation
What is the cumulative mass curve?
Mass-Curve is a plot of the cumulative flow volumes as function of time. It is used to determine the critical period of a reservoir showing the relationship between withdraw and addition to the reservoir.
What is the first step in conducting improvement curve analysis?
histpry
What is a Bézier curve?
A Bézier curve is a parametric curve defiend by a set of control points, two of which are the ends of the curve, and the others determine its shape.
What is needed to determine equilibrium price of a good or a service?
a supply curve and a demand curveA supply curve and a demand curve.

What is it that causes a production possibilities curve to shift outward or inward?
Improvement of management efficiency.
How can one determine the concentration of a sample using a calibration curve?
To determine the concentration of a sample using a calibration curve, you first need to measure the response of known standard samples with known concentrations. Then, plot a calibration curve by graphing the response against the concentration. Finally, measure the response of the unknown sample and use the calibration curve to determine its concentration by finding where its response falls on the curve.
Which would cause a rightward shift in the supply curve for telephone service?
An improvement in telephone technology.
How can one determine the pKa from a titration curve?
To determine the pKa from a titration curve, identify the point on the curve where the pH is equal to the pKa value. This point represents the halfway point of the buffering region, where the concentration of the acid and its conjugate base are equal.
How can one utilize a calibration curve to determine the concentration of a substance?
To determine the concentration of a substance using a calibration curve, one must first create the curve by measuring known concentrations of the substance and their corresponding signals. Then, by measuring the signal of an unknown sample and comparing it to the curve, the concentration of the substance can be determined.
What are the three characteristics of a supply curve?
The three characteristics of a supply curve are the slope, shift, and the curve's position. Together they help determine supply and demand trends.
What is a bezier?
A bezier is another term for a Bézier curve, a parametric curve defiend by a set of control points, two of which are the ends of the curve, and the others determine its shape.
