Records show10% of their sapphire bracelets are returned. If five customers buy a sapphire bracelet, then what is the probability that none of them will retrun it?

725 parts per hour.

step-by-step explanation:

hi there, this answer is actually really simple.

you can set it up as 1450/2 or 3625/5 to find the answer.

they want to know how much per hour is being made, so you just divide.

1450/2=725.

and that's how many are produced per hour.

hope this . : )
