In proof testing of circuit boards, the probability that any particular diode will fail is 0.01. suppose a circuit board contains 200 diodes. (a) how many diodes would you expect to fail? 2 correct: your answer is correct. diodes what is the standard deviation of the number that are expected to fail? (round your answer to three decimal places.)

  a) 2  b) 1.407

Step-by-step explanation:

Given : The probability that any particular diode will fail : p=0.01

The number of diodes in a circuit : n= 200

The number of diodes expected to fail will be :-

Hence, the number of diodes expected to fail =2

The standard deviation of the number that are expected to fail will be :-

[Rounded to three decimal places.]

Hence, the standard deviation of the number that are expected to fail= 1.407

circumference divided by 3.141592654 then timesthe radius twice

circumference divided by 3.141592654 then timesthe radius twice

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
