In this section we use r to denote the value of the linear correlation coefficient. why do we refer to this correlation coofficient as being linear? choose the correct answer below a. the term linear refers to a straight line, and r measures the fraction of the points the best line passes trough. b. the term linear refers to a straight line that passes through the average values of the paired data, and r measures how well a scatterplot fits a straight-line pattem c. the term linear refers to a straight line, and r measures how well a scatterplot fits a straight-line pattern d. the term linear refers to the straight line that passes through the greatost number of points, and r meansures the fraction of the points the line passes through

Aspacecraft can attain a stable orbit 300 kilometers above earth if it reaches a velocity of 7.7 kilometers per second. the formula for a rocket's maximum velocity v in kilometers per second is vequalsminus0.0098tplusc ln upper r, where t is the firing time in seconds, c is the velocity of the exhaust in kilometers per second, and r is the ratio of the mass of the rocket filled with fuel to the mass of the rocket without fuel. find the velocity of a spacecraft whose booster rocket has a mass ratio of 20, an exhaust velocity of 2.1 km/s, and a firing time of 15 s. can the spacecraft achieve a stable orbit 300 km above earth?
