Your manufacturing plant produces air bags, and it is known that 20% of them are defective. Five air bags are tested. (a) Find the probability that two of them are defective. (Round your answer to four decimal places.)

1.0000

Step-by-step explanation:

It is know that 20% of air bags produced by the manufacturing plant are defective.

20% of x

Therefore, the probability that two are defective will be

20/100 × 5

0.2×5=1.0000

x= cost per bracelet

number of bracelets * x + shipping charge = total cost

so

9x+9=72

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft
