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

Valentino starts with a population of 1,500 amoebas that increases 35% in size every hour for a number of hours, h. the expression 1,500(1+0.35)h finds the number of amoebas after h hours. which statement about this expression is true? a. it is the initial population raised to the growth factor after h hours. b. it is the sum of the initial population and the percent increase. c. it is the sum of the initial population and the growth factor after h hours. d. it is the product of the initial population and the growth factor after h hours.
