Answer:
5x+y=12
Step-by-step explanation:
10x+2y=-2=5x+y=12
Total students 5+16+42+22+5 = 90
0-1's probability is 5 / 90 = 5.5% about
2-3's probability is 16 / 90 = 17.7% about
4-5's probability is 42 / 60 = 46.6% about
6-7's probability is 22 / 90 = 24.4% about
8+'s probability is 5 / 90 = 5.5% about
(percentages not rounded, just cut off at the first decimal)
Time = Distance / Speed
= 80 mi / 45 mph
= 16 / 9 hours
= 1.778 hours.
