In a pacemaker factory, all pacemakers must go through a rigorous quality assurance check before being shipped. The table shows the results
of the quality assurance checks. The factory can submit a complaint if the
inspector is correct less than 80% of the time. Find the probability that
the inspector will be successful on any given pacemaker check, rounding
your decimal answer to three decimal places. Also: Can the factory submit
a complaint about this inspector?

question:

could we have options?

1^3 + 2^3 + 3^3 +4^3 = (1+2+3+4)^2

step-by-step explanation:

i am only able to answer the first part. i am not sure about the second part. sorry

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
