What should the mean diameter, in inches, be in order to minimize the fraction of bearings that are scrapped?

hello your question is incomplete attached below is the missing part of the question

answer :  3.000 inches

Step-by-step explanation:

In order to minimize the fraction of bearings that are to be scrapped The mean diameter in inches should be 3.000 inches and this is because the diameter of the bearings follows a normal distribution.

The higher the fraction of accepted bearings, the minimal the fraction of rejected fraction bearings

specifications of bearing diameter; 3.000 ± 0.002

answer: all of the odd numbers were opened

the first person was the one that was opening all of the lockers. since one is odd, this causes all of the odd number lockers to be opened in the end.

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
