In planning for tightening 500 bolts, it was measured that the bolt head twists off at a mean torque of 20N-m with a standard deviation of 1 N-m. If only one failure can be accepted in this group, what is the highest mean torque the wrench should be set at if the standard deviation of the wrench is 1.5N-m

hi how are you doing today? if you ever need just tell me

step-by-step explanation:

i those same problems in math and dont know how to do them

c

step-by-step explanation:

the circumference of a circle is, 10.676 cm.

step-by-step explanation:

the formula for circumference of a circle is given by:

where

c is the circumference of a circle and

d is the diameter of a circle.

given: diameter(d) = 3.4 cm and use

substitute these values in [1] we get;

cm

therefore, the circumference of a circle is, 10.676 cm
