ANSWER
The key features are:
1. The y-intercept which is .
This means that at time , the Masons are
miles away from home.
2. The <em>x-intercept</em> which is .
This means after hours the Masons reached home.
The reason is that miles. This means that there is no distance between the Masons and their home.
3. The slope of the graph which is tells us the speed at which they travel towards their home.
.
This means they traveled at a speed of .
The negative slope of the graph tell us that the distance is reducing as they approach their home.

Answer:
0.38% probability that the sample contains exactly two defective parts.
Step-by-step explanation:
For each part, there are only two possible outcomes. Either it is defective, or it is not. The probabilities for each part being defective are independent from each other. So we use the binomial probability distribution to solve this problem.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which is the number of different combinations of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
In this problem we have that:
What is the probability that the sample contains exactly two defective parts?
This is
0.38% probability that the sample contains exactly two defective parts.
