Someone please help me! Studying for finals and don’t understand how to complete problems like this! Thank you!
Drupady [299]

Answer:

(d). \frac{152}{377}

Step-by-step explanation:

sin² β + cos² β = 1

cos (α + β) = cos α cos β - sin α sin β

cos α = √(1 - \frac{400}{841} ) = 21 / 29

cos β = 12 / 13

sin β = √(1 - \frac{144}{169} ) = 5 / 13

sin α = 20 / 29

cos (α + β) = \frac{21}{29} × \frac{12}{13} - \frac{20}{29} × \frac{5}{13} = \frac{152}{377}

An inspector samples four PC’s from a steady stream of computers that is known to be 12% nonconforming. What is the probability
yarga [219]

Answer: 0.067

Step-by-step explanation:

Binomial distribution formula :-

P(X)=^nC_xp^x(1-p)^{n-x}, here P(x) is the probability of getting success in x trials , n is total number of trials and p is the probability of getting success in each trial.

Given : n = 4 , p = 12 % = 0.12 and x =2

Then , P(2)=^4C_2(0.12)^2(1-0.12)^{4-2}

\Rightarrow\ P(2)=\dfrac{4!}{2!2!}(0.12)^2(0.88)^2=0.06690816\approx0.067

∴ The probability of selecting two nonconforming units in the sample = 0.067
