Length (inches)
Forearm Length, Group B
9 10 11 12
Length (inches)
Based on visual inspection of the dot plots, which group appears to have the longer average forearm length?
O Group A, because three children in the group have the least forearm length of 9 inches
O Group B, because three children in the group have the least forearm length of 9 inches
O Group A, because two children have a forearm length longer than 10 inches
O Group B, because seven children have a forearm length longer than 10 inches

step-by-step explanation:

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional

answer: no

step-by-step explanation: because the big angle will spread away the 2 side that it is on and make the opposite side even longer.
