A manufacturer of baseball hats claims that approximately 30% of people regularly wear baseball hats. From a random sample of 20 students at your school, you find that only four wear baseball hats regularly. This gives you reason to believe that the manufacturer’s claim of 30% is too high. Let the digits 0–2 represent wearing a baseball hat (H) and the digits 3–9 represent not wearing a baseball hat (N). Use the table of random numbers to run one trial of this simulation.

it is true

step-by-step explanation:

all the combinations add up i used   calculator

a is the right answer

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

the correct answer is c) 2.
