The U. S. Department of Transportation wants to see if there is a relationship between motor vehicle fatality rate (units=fatalities per 1000 licenses) and the percentage of licensed drivers over 21 (units -10%). A regression analysis on 13 cities revealed Exi - 110.50, 2x4-939.47, Eyi = 31.20, 2y2 = 95.96, and Exiyi = 263.06. What is the interpretation of B1?

a. For an increase of 0.001 fatalities/license in the motor vehicle fatality rate, the average percentage of licensed drivers over 21 decreases by 0.9727%.
b. For an increase of 10% in percentage of licensed drivers over 21, the average motor vehicle fatality rate decreases by 0.1015 fatalities/license.
c. For an increase of 10% in percentage of licensed drivers over 21, the average motor vehicle fatality rate decreases by 0.0097 fatalities/license.
d. For an increase of 0.001 fatalities/license in the motor vehicle fatality rate, the average percentage of licensed drivers over 21 decreases by 9.7273%.
e. None of the answers is correct

An airplane consumes fuel at a constant rate while flying through clear skies, and it consumes fuel at a rate of 64 gallons per minute while flying through rain clouds. let c represent the number of minutes the plane can fly through clear skies and r represent the number of minutes the plane can fly through rain clouds without consuming all of its fuel. 56c+64r < 900056c+64r< 9000 according to the inequality, at what rate does the airplane consume fuel while flying through clear skies, and how much fuel does it have before takeoff? the airplane consumes fuel at a rate of gallons per minute while flying through clear skies, and it has gallons of fuel before takeoff. does the airplane have enough fuel to fly for 60 minutes through clear skies and 90 minutes through rain clouds?
