Temperature affects the speed of sound. the speed (v) of sound near earth's surface, in

meters per second, is given by v = 20vt + 273, where t stands for the temperature of

the air in degrees celsius. if the speed of sounds is 300 meters per second, what is the

temperature in degrees celsius?

Aregression was run to determine if there is a relationship between hours of tv watched per day (x) and number of situps a person can do (y). the results of the regression were: y=ax+b a=-0.662 b=30.418 r2=0.703921 r=-0.839
