1. students in a science class investigated how the speed of sound changes with the air temperature outside. the data are shown in the scatterplot. based on the scatterplot, what is the best prediction of the speed of sound when the air temperature is 50°c?

2linear scatterplots have three different types of correlation: positive, negative and none (no
correlation). describe a real life scenario for one of these three types of scatterplots.

Answer

The student should have determined that a reasonable trend line (line on a graph showing the

general direction a group of points seems to be heading) for the given scatterplot (a graph of plotted

points that shows the relationship between two sets of data) would pass through the points located at

approximately(2,334) and20,344 . When this line is extended to the vertical line (in an up-down

direction) on the graph that represents 50 °C, it will pass close to a point on the graph located at(50,360)

. The meaning of this point is that the speed of sound will be approximately 360 meters per

second when the air temperature is 50 °C.

multiplication is multiplication.   it might feel harder depending on what level of math you are in, but generally it will be the same old stuff, while implementing some new concepts and methods of solving work.
