The type of part being manufactured today should be 1.27 inches wide, with a tolerance of 0.04 inches. if a part does not meet the size requirement, it must be rejected. you have 4 parts to inspect. they have the following widths. how many must be rejected? 1.275 inches, 1.300 inches, 1.266 inches, 1.255 inches a. none b. 1 c. 2 d. 3 e. 4

option: A is correct.

None of the parts will get rejected.

Step-by-step explanation:

The type of part being manufactured today should be 1.27 inches wide, with a tolerance of 0.04 inches.

i.e. the range upto which the manufactured part won't be rejected are:

lower value:

1.27-0.04=1.23

and 1.27+0.04=1.31

So, any part whose width is between:

1.23 inches - 1.31 inches won't get rejected.

1)

1.275 inches.

as 1.275 inches lies between 1.23-1.31 inches.

Hence it won't get rejected.

2)

1.300 inches.

As it also lies between 1.23-1.31 inches.

Hence it won't get rejected.

3)

1.266 inches.

As it also lies between 1.23-1.31 inches.

Hence it won't get rejected.

4)

1.255 inches

As it also lies between 1.23-1.31 inches.

Hence it won't get rejected.

This means that none of the part will get rejected.

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right
