Step-by-step explanation:
a) mode = 3 ( cause most number of car that have 3 teachers)
b) median = 3 (1,1,1,2,2,2,2,3,3,3,3,3,3,4,4) the middle position)
c) mean = (1*3 + 2*4 +3*6 + 4*2)/15 = 2.467(average)

Answer:
72 kph
Step-by-step explanation:
The first sentence tells you the speeds are proportional. So, you can write the proportion ...
kph/mph = 120/75 = x/45
Multiplying by 45 gives x:
x = (45)(120/75) = 72
72 kph is 45 mph.
Well if FG is 4x and GH is 2x the you add them to get 6x for FH. Solve for x so 6x=18 which means x=3. Hope this helps
-2/3 is the correct answer
3 tens= 30
3 tens 3 tenth= 30.3
30-30.3= -0.3
