Drake needs to drill holes in a wooden plank. The holes will have a diameter of 0.5 millimeters, with an error allowance of 0.05
Tanzania [10]

Answer:

 |x − 0.5| = 0.05

Step-by-step explanation:

Here x represents the diameter,

Since, an error of 0.05 millimeters is allowance in diameter,

Thus, the maximum acceptable diameter = x + 0.05,

And, the minimum acceptable diameter = x - 0.05

According to the question,

The holes will have a diameter of 0.5 millimeters,

Thus, x - 0.05 < 0.5  and 0.5 < x + 0.05

⇒ x - 0.5 < 0.05 and x - 0.5 > - 0.05  

⇒ x - 0.5 < 0.05 and -(x -0.5) < 0.05

⇒ |x-0.5| < 0.05

⇒ Option D is correct.

Harrizon [31]

Answer: A.  We are​ 99% confident that the interval from 4.1 to 5.6 actually does contain the true value of mu.

Step-by-step explanation:

The correct interpretation of a 99% confidence interval is that we are 99% confident that the true population mean falls in it.

Given  99% confidence interval : 4.1

Then, the correct interpretation :  We are​ 99% confident that the interval from 4.1 to 5.6 actually does contain the true value of mu.
