Samples of emissions from three suppliers are classified for conformance to air-quality specifications. the results from 100 samples are summarized as follows:
conforms
yes no
supplier
1 22 8
2 25 5
3 30 10
let a denote the event that a sample is from supplier 1, and let b denote the event that a sample conforms to specifications.
(a) find p(a)
(b) find p(b)
(c) find p(b∣a)
(d) find p(a∪b)
(e) are a and 8 independent? justify your answer.

the answer is 4.8 units on e2020.

80° is the measure of gh

step-by-step explanation:

circle f is congruent to circle j

we have two circle with center f and j.

both circles are congruent. the radius of the circle would be equal.

see the attachment for the circle.

we are given ∠efd ≅ ∠gjh

therefore, arc (ed) = arc (gh)     (∴ circle f is congruent to circle j)

but ∠dfe=80°=arc (ed)

therefore, arc (gh) = 80°

thus, 80° is the measure of gh

10+4√2 is the answer. i dont have the time to explain.
