A manufacturing process is designed to produce bolts with a 0.75-inch diameter. Once each day, a random sample of 36 bolts is selected and the bolt diameters recorded. If the resulting sample mean is less than 0.730 inches or greater than 0.770 inches, the process is shut down for adjustment. The standard deviation for diameter is 0.04 inches. What is the probability that the manufacturing line will be shut down unnecessarily? (Hint: Find the probability of observing an x in the shutdown range when the true process mean really is 0.75 inches. Round your answer to four decimal places.)

There are 25 students in Mrs. Venetozzi’s class at the beginning of the school year, and the average number of siblings for each student is 3. A new student with 8 siblings joins the class in November.The average number of siblings that each student has is

Select a Value
* larger than the original average.
*smaller than the original average.
*the same as the original average.

Answers

Adding the student with eight siblings will increase the class average amount of siblings because this student has more siblings than the average.

Therefore, the average number of siblings that each student has is larger than the original average.

The average number of siblings that each student has is larger than the original average.

What is the Average number of students?

We are told that the average number of siblings for the 25 students is 3.

Now, a new student with 8 siblings joins the class.

This addition will increase the class average amount of siblings due to the fact that this new student has 8 siblings which is 5 more than the class average.

Thus, we can conclude that the average number of siblings that each student has is larger than the original average.

The perimeter of a pool table is 30 feet. The table is twice as long as it is wide. What is the length of the pool table?

Answers

So, 30 is the perimeter. We are told the table is twice as long as it is wide.

So, we have think of 2 numbers, one being twice as big than the other. So, it is a rectangle The two number represents the length and the width. To find the perimeter we add all the lengths and the widths. Since the pool table is a rectangle we have two lengths and two widths.

So,

the tow numbers be 10 and 5. 5 is half of 10 and, when multiplied by 2 it is 10. So just to make sure the numbers 5 and 10 work out lets do a calculation.

So,

10+5+10+5 = 30feet. This proves that the sides are these two numbers.
