One yard is equal to three feet so 27/3= 9 yards
Alright, given that it's a male then
total of 4+6+2+2 or 14 pepole are male
4 of them are freshmen
so the probalbity would be 4/14 or 2/7 or aprox 0.28571428571428571428571428571429

f(x) = 10 + 20x
so if you rent the bike for a few hours that is
1 hr.............................10 + 20(1)
2 hrs..........................10 + 20(2)
3 hrs..........................10 + 20(3)
so the cost is really some fixed 10 + 20 bucks per hour, usually the 10 bucks is for some paperwork fee, so you go to the bike shop, and they'd say, ok is 10 bucks to set up a membership and 20 bucks per hour for using it, thereabouts.
f(100) = 10 + 20(100) => f(100) = 2010.
f(100), the cost of renting the bike for 100 hours.
D is a function because there are no repeated x values
for example b is not a function because we have (0,-7) and (0,-9)
