A light bulb factory produces 1,188 light bulbs every hour. Approximately 3.83% of the light bulbs are defective, and do not wor
andreev551 [17]

Answer:

The standard deviation of the number of defective bulbs produced in an hour is 6.615

Step-by-step explanation:

Binomial probability distribution

Probability of exactly x sucesses on n repeated trials, with p probability.

The expected value of the binomial distribution is:

E(X) = np

The standard deviation of the binomial distribution is:

\sqrt{V(X)} = \sqrt{np(1-p)}

In this problem, we have that:

p = 0.0383, n = 1188

What is the standard deviation of the number of defective bulbs produced in an hour

\sqrt{V(X)} = \sqrt{np(1-p)} = \sqrt{1188*0.0383*(1-0.0383)} = 6.615

The standard deviation of the number of defective bulbs produced in an hour is 6.615

let x = Julio's number and y = answer for Julio's number substrates 17

x - 17 = y \\ y ( - 3) =  - 39 \\

by using substitution method, you will get

x = 30 \\ y = 13

so the answer is 30
