Answer:
<em>The approximate probability that a random vehicle is a passenger car is 74.67%</em>
Step-by-step explanation:
<u>Probability</u>
The traffic engineer records 112 passenger cars, 18 light trucks, and 20 heavy trucks. The total of vehicles recorded is n=112+18+20 = 150.
We are required to find the probability that a randomly selected vehicle crossing the bridge is a passenger car. There are 112 passenger cars, thus the probability is:
p = 0.7467
p = 74.67%
The approximate probability that a random vehicle is a passenger car is 74.67%

The answer is 4.4102. We know the length of one side is 2.4 and the length of the other side is half of 7.4. If we use Pythagorean’s theorem to find the hypotenuse we get (7.4/2)^2 + 2.4^2 = X^2. By solving for x we get x= root( (7.4/2)^2 + 2.4^2). So x is approximately 4.41.
