When circuit boards used in the manufacture of compact disc players are tested, the long-run percentage of defectives is 5%. If 25 such discs are tested what is the probability that a) 20 are not defective. b) At least 20 are not defectives. c) Find the average number of defectives.

all the angles opposite to the angle 150 would be 150 and all the angles that are next to 150 are 30 because they equal 180 it you add it up.

step-by-step explanation:

6 and 24

step-by-step explanation:

6 x 4 = 24

46

step-by-step explanation:

given

height = 168 cm

formula

height =2.47*f+54.13

solution

168 = 2.47f + 54.13             subtract 54.13 from both sides

168 - 54.13   = 2.47f             combine

113.87 = 2.47f                     divide by 2.47

113.87 / 2.47 = f                   combine

46.1 = f  

answer: 46 cm
