The aspect ratio is used when calculating the aerodynamic efficiency of the wing of a plane for a standard wing area, the function a(s)=s^2/36 can be used to find the aspect ratio depending on the wingspan i’m feet. if one glider has an aspect ratio of 5.7, which system of equations and solution can be used to represent the wingspan of the glider? round solution to the nearest tenth if necessary.

y=s^2/36 and y=5.7; 14.3 ft
y=5.7s^2 and y=36; s=2.5ft
y=36s^2 and y=0; s=0.4 ft
y=s^2/36 +5.7 and y=0; s=5.5 ft

Apsychology student wishes to investigate differences in political opinions between business majors and political science majors at her college. she randomly selects 100 students from the 260 business majors and 100 students from the 180 political science majors. does this sampling plan result in a simple random sample? why or why not? no, because each group of 200 students in the sample does not have the same chance of being selected. yes, because each group of 200 students in the sample has the same chance of being selected. no, because each individual student does not have an equal chance of being selected. yes, because each individual student has the same chance of being selected.

The weight v of an object on venus varies directly with its weight e on earth. a person weighing 120 lb on earth would weigh 106 lb on venus. how much would a person weighing 150 lb on earth weigh on venus?
