Prices and sizes of 100 diamonds were collected. The data in four scatterplots, each using either a linear or a log scale for the X and Y axis. Which of the types of models would be the most accurate at predicting the price of a diamond based on the size (carat)?
Need to know which:
Linear
Exponential
Logarithmic
Power
Homework Answers
The slope of a log-log plot gives the power of the relationship, and a straight line is an indication that a definite power relationship exists.
Therefore option 4

Write a Java program which uses the LWJGL library to draw a window of 640x480 (with a black background). The coordinate system should be centered in this window. Your program will read a file titled coordinates.txt and draw the corresponding filled polygon in this window using the scanline polygon fill algorithm. Each specified polygon should be filled in the color specified in the text file and then undergo the transformations specified in the input file before being drawn on the...

PROBLEM 4 (20 pts) Water at 25 °C is used to cool oil from 120 °C to 80 °C. Oil flows at a rate of 1 kg/s in a tube of inside diameter 1.6 cm and outside diameter 1.9 cm. The tube makes 18 passes in a shell. Water flows through the shell at a rate of 1.5 kg/s. The water side heat transfer coefficient is 12,000 W/m2°C. Oil properties at 100 °C are: Cp = 2219J/(kg.), k = 0.137...

B Frequency Response Modeling Frequency response modeling of a linear system is based on the premise that the dynamics of a linear system can be recovered from a knowledge of how the system responds to sinusoidal inputs. (This will be made mathematically precise in Theorem 13.) In other words, to determine (or iden- tify) a linear system, all one has to do is observe how the system reacts to sinusoidal...
