The mean is the average.
Total the numbers and divide by the quantity of numbers.
2 +2 + 3 + 3 +4 +4 +4 +5 +5 +5 +5 + 6 = 48
48 / 12 = 4
The answer is B.4
Answer:
Step-by-step explanation:
No because there could simply be more older drivers on the road.
Let the length of side AB be $x$, then

Therefore, the perimeter of ABCDE is 2(12) + 2(4) + 6 = 24 + 8 + 6 = 38 in.
So when you have data given this kind of form... you should convert to decimal first.
So that would be:
a ≈ 2.12
b = 3.5
c = 2.5
Now just place the simple perimeter formula, and sum all sides.
