6. 20 ft Below sea level is -20 and 15 ft. Below sea level is -15, add -20+-15 (the new integer is -35)
Even integers have the form 2k so three consecutive even integers will be 2k,2(k+1),2(k+2)
so there sum will be
2k+2(k+1)+2(k+2)=24
simplifying
2k+2k+2+2k+4=24
adding like terms
6k+6=24
6k=18
k=3
so the three consecutive even integers are
2(3),2(3+1),2(3+2)
6,8,10
Probablity=desiredoutcomes/totalpossibleoutcomes
see which ones fit
dimes and quarters are over 9 cents
there are 11+3 or 14 of them
total outcomes=12+9+11+3=35
probablity=14/35=2/5
probablity is 2/5
