30 mi per h, means 30 mi/1h.
So mi should be on y-axis and hours on x -axis.
The point should have 1 h (on x -axis) and 30 mi (on y-axis).
The only graph that has this point is G.
Answer:
10x
Step-by-step explanation:
There are three groups of people: 25 years old and younger, between 25 to 50, and 50 years old and older. Their fractions must equal to 1 because these three together form the whole.
1 = 1/3 + 2/7 + x
where x is the fraction for people ages 25 to 50 years old
x = 8/21
So, the actual number of people ages 25 to 50 years old is:
84(8/21) = 32 people
if you pick G you don't have to pick D so I didn't I picked B so that I could pick E and they didn't say any rules about F so I picked G,B,E,F
