Industrial quality control programs often include inspection of incoming materials from suppliers. if parts are purchased in large lots, a typical plan might be to select 20 parts at random from a lot and inspect them. suppose that a lot is judged acceptable if one or fewer of these 20 parts are defective parts. if more than one part is defective, the lot is rejected and returned to the supplier. find the probability of accepting lots that have each of the following

Answer: d. 39 cmin the diagram, the approximate length of the minor arc de is 39 centimetres.step-by-step explanation: the formula for the length of an arc in a circle is as displayed below.let the length of the minor arc de = xx = 2( pi )r × angle of sector / 360°from this, we will substitute the values given from the problem into the formula to obtain the length of the minor arc de.x = 2( pi )r × angle of sector / 360°r = radius = 25cmpi as an approximate value = 3.14angle of sector = 120°x = 2( 3.14 )( 25 ) × 120° / 360°x = 157 × 1 / 4x = 39.25x = 39 ( rounded to the nearest whole number as an approximate value )
