A bolt fabrication machine makes bolts with a target length of u = 15.125 millimeters. The machine has some variability, so the standard deviation of the length is o = 0.175 millimeter. The machine operator inspects a random sample of 12 bolts each hour for quality control
purposes and records the sample mean diameter, X. Assuming the process is working properly, what are the mean and standard deviation of
the sampling distribution of x

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm

aloha~! my name is zalgo and i am here to you out on this amazing day. to answer your question, yes, nonzero numbers can have a greatest common factor and that would be 1. still don't get it? let me considering every number is divisible by 1 and hence every number has 1 as a factor of theirs. so, if 2 nonzero numbers didn't share any gcf (greatest common factor), they would still have a factor in common and that would be 1.

i hope that this ! : p

(by the way, do you mind marking me as brainliest? i'd greatly appreciate it! mahalo! x3)

x= cost per bracelet

number of bracelets * x + shipping charge = total cost

so

9x+9=72
