Step-by-step explanation:

a) BEC=90°(right angle triangle)

total degrees of a triangle is 180°

therefore let the missing angle be x

it will be 90+27+x=180

value of X=63°

therefore <BCE=63°

b) since ΔBAD is an

isosceles triangle

ABE must also be 52°total degrees of a triangle is 180°

let the missing angle be Y

it will be 52+52+Y=180

value of Y is 76

therefore <BAD=76°

Suppose a shipment of 190 electronic components contains 3 defective components. To determine whether the shipment should be ac

PolarNik [594]

Answer:

0.0467

Step-by-step explanation:

Probabilty of being defective is $\frac{3}{190}$

So probability of being good is $\frac{187}{190}$

Now,

Probability that all 3 of them are good is:

$\frac{187}{190}^{3}=0.9533$

Now, to find probability of rejection, we subtract the now found probability from 1. Thus, we have:

1 - 0.9533 = 0.0467
