The first one because 3*2 =6 and 4.5*2= 9 and 4*2=8 and they are all the same as the other triangle
There are 5 blue shirts and only one is big, so the probability would be 1/12. The percentage would be approximately 8%
To find the constant variation, solve for only one hour (in this case).
Divide 100 with 2
100/2 = 50/1
Each hour is 50 miles driven, so your constant variation is 50 mph
