For problem 12 you would do 44.8 times 5 and that would give you 224 miles.
Problem 13: In the first race he drove at an average speed of 149 miles per hour. I got this by dividing 2.5 by 372.5. In the second race he drove 144 miles per hour. I determined this by dividing 3.2 by 460.8. Therefore, in his first race he drove the fastest average speed.
I hope this helps!
Answer:
The two experiments together can be performed in 45 distinct ways.
Step-by-step explanation:
Number of distinct ways to perform first experiment = 5
Number of distinct ways to perform first experiment = 9
For each distinct way the first experiment is performed there are 9 distinct ways to perform the second experiment. Also, the way each experiment is performed is independent of the other experiment (important assumption).
So, according to the fundamental rule of counting the total number of ways to perform both the experiments must be equal to the product of number of ways in which each experiment can be performed.
Therefore, the two experiments can be performed together in 5 x 9 = 45 distinct ways.

Answer:
0.7755
Step-by-step explanation:
If 120 CDs are defective, the number of non-defective CDs in the batch is:
In order for the batch to be accepted, all of the 4 CDs in the sample must not be defective, the probability of that happening is:
The probability that the entire batch will be accepted is 0.7755.
N=18.75
