In proof testing of circuit boards, the probability that any particular diode will fail is . suppose a circuit board contains diodes. how many diodes would you expect to fail, and what is the standard deviation of the number that are expected to fail? what is the (approximate) probability that at least four diodes will fail on a randomly selected board? if five boards are shipped to a particular customer, how likely is it that at least four of them will work properly? (a board works properly only if all its diodes work.)

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)

the options are kind of confusing. i can tell you what i see going on here when i look at the graph.

the class and exam medians are closely related, and it looks like the low outlier on the exam did pull the median lower. [tex][/tex]
