From what I think; 
8.216secs - 1 wheel; 3.652- 1 hood
for I toy car with a wheel and hood the total time is 8.216+ 3.652 = 11.868secs
let x secs be the total time taken to put a wheel and hood for 42 cars 
x secs = 42 cars × the total time for one car
x secs = 42× 11.868 
x secs= 498.456 secs
        
             
        
        
        
Answer:
a = 1
Step-by-step explanation:
Original Equation:
-1 + 8 = 10 - 3a
Add 1 to both sides
8 = 11 - 3a
Subtract 11 from both sides
-3 = -3a
Divide both sides by -3
a = 1

Of the last 100 customers entering a computer shop, 25 have purchased a computer. If the classical probability assessment for computing probability is used, the probability that the next customer will purchase a computer is:
Answer: In classical probability, all the outcomes are equally likely. In this situation, the next customer can either buy the computer or not. Therefore, the probability that the next customer will purchase a computer is:

Here the previous outcomes will not have any impact on the new outcomes. That is the reason the probability that the next customer will purchase a computer is 0.5
Classical probability measures the likelihood of something happening. It also means that every statistical experiment will contain elements that are equally likely to happen.
The example of classical probability is fair dice roll because it is equally probable that it will land on any of the 6 numbers on the die: 1, 2, 3, 4, 5, or 6.
