A manufacturer of bolts has a quality-control policy that requires it to destroy any bolts that are more than 2 standard deviat

n200080 [17]

bolts of length more than $13+0.2$ , and less than $13-0.2$ will be destroyed

= 13.20 cm and 12.80 cm

Step-by-step explanation:

Here we have , A manufacturer of bolts has a quality-control policy that requires it to destroy any bolts that are more than 2 standard deviations from the mean. The quality-control engineer knows that the bolts coming off the assembly line have mean length of 13 cm with a standard deviation of 0.10 cm. We need to find For what lengths will a bolt be destroyed .Let's find out:

A manufacturer of bolts has a quality control policy that requires it destroy any bolts that are more than 2 standard deviations from the mean.

mean length= $13 cm$

standard deviation= $0.10 cm$

2 standard deviation from mean= $13 \pm (2(0.10))$

Therefore, bolts of length more than $13+0.2$ , and less than $13-0.2$ will be destroyed

= 13.20 cm and 12.80 cm

Which of the following is an even function?

12345 [234]

Answer:

B. g(x) = 2x² + 1

Step-by-step explanation:

Even function has following property:

g(x) = g(-x)

It is easy to show this works with the second choice only. All the others don't work:

g(x) = (x - 1)² + 1
g(-x) = (-x - 1)² + 1

This is not correct as x - 1 ≠ -x - 1 so as their squares, so g(x) ≠ g(-x)

The last two choices are not even similarly.
