20. Solve the following logarithmic equation for the unknown variable and show all work. 3 loga * -log125 = 0. [5 Points). 21. The following graphs show the scatterplot relationships for two different sets of data. Describe each graph as Linear or Non-Linear by circling the correct choice. For each graph also choose which regression equation would be the best choice to use for developing a mathematical model to describe the data, i.e. y=mx+b y=ax? +bx+c y=ca'. [4 Points). Linear...

1. Explore the data: create a scatterplot
. 1a. Type the data into a blank SPSS spreadsheet. Name
variables as Distance and Snowfall respectively. Go to
Graphs-Legacy Dialogs-Scatter/Dot-Simple Scatter-Define. In the
window that follows, select Distance into X axis and Snowfall into
Y axis. Click on OK.
1b.Double click on the scatter plot to activate it. Double click
on the horizontal axis and select the Scale tab. At Auto, uncheck
all boxes. At...

Date: Name: Storm Tracker Portfolio Worksheet PRECALCULUS: PARAMETRIC FUNCTIONS Directions: Meteorologists use sophisticated models to predict the occurrence, duration, and trajectory of weather events. They build their models based on observations that they have made in the past. By understanding how previous weather events evolved, meteooogists can apply that knowledge to future weather Parametric equations can be used to graph the path of an object in space. For example, used to describe the path of a...
