â¢â¢ A radio broadcast antenna is 36.00 km from your house. Suppose an airplane is flying 2.230 km above the line connecting the broadcast antenna and your radio, and that waves reflected from the airplane travel 88.00 wavelengths farther than waves that travel directly from the antenna to your house.
For example, in 2014 the median earnings of young adults with a bachelor's degree ($49,900) were 66 percent higher than the median earnings of young adult high school completers ($30,000). The median earnings of young adult high school completers were 20 percent higher than the median earnings of those without a high school credential ($25,000).
College graduates aged 25 to 32 who are working full time earn about $17,500 more annually than their peers who have only a high school diploma, according to the Pew Research Centre, a think-tank. But not all degrees are equally useful.
