Necessary and sufficient conditions for application of binomial distribution :
1. trial must be Bernoulli, i.e. exactly two outcomes (defective or not defective)
2. number of trails is known and not dependent on outcomes (2).
3. probability of each trial must be known and is constant throughout trials (3/10, with replacement)
4. all trials are random and independent of each other.

Answer:

503 inches (rounded to the nearest whole number)

Step-by-step explanation:

First, we must calculate the wheel's circumference, or in other words, the distance around the wheel. We can do this by using the below equation:

C=\pi d when d is the diameter

Because we know that the wheel's diameter is 16 inches, we can plug it into the equation:

C=\pi (16)\\C=16\pi

Now, because we know that the wheel makes 10 revolutions, we calculate the distance it travelled by multiplying the circumference by 10.

16\pi *10\\= 160\pi

= 503 inches when rounded to a whole number

Therefore, the wheel travelled approximately 503 inches.

I hope this helps!

AveGali [126]

Answer:

    The career planning process is ongoing and sequential. Since it is fluid rather than chronological, you move to the next step only when you are ready to do so, and you may move back and forth between steps at any given time. The career planning process is also cyclic. When career change is desired anytime during your work life, you may repeat the process once again. Data from the U.S. Bureau of Labor Statistics indicates that the majority of members of the labor force will make three to four major changes in their career during their 35 to 45 years of working. Because human beings are complex, each of us has unique aspirations, goals, potential for development, and limitations. Although we can follow the same process, career planning outcomes must be individualized.
