BRAINLEST FOR CORRECT ANSWER PLEASE PLEASSE HELP MEE Figure EFGH on the grid below represents a trapezoidal plate at its starting position on a rotating machine platform:
(Image attached)
The plate is rotated 360° about the origin in the clockwise direction. Which of the following is formed when the arcs of rotation are drawn for each point as it is rotated?

A They form parallel segments.
B They form perpendicular segments.
C They form congruent segments.
D They form concentric circles.

My guess is D but then again I don't trust myself lol

In a sample of 2023 u.s. adults, 373 said franklin roosevelt was the best president since world war ii. two u.s. adults are selected at random from the population of all u.s. adults without replacement. assuming the sample is representative of all u.s. adults, complete parts (a) through (d). (a) find the probability that both adults say franklin roosevelt was the best president since world war ii. the probability that both adults say franklin roosevelt was the best president since world war ii is (round to three decimal places as needed.) (b) find the probability that neither adult says franklin roosevelt was the best president since world war ii. the probability that neither adult says franklin roosevelt was the best president since world war ii is (round to three decimal places as needed.) (c) find the probability that at least one of the two adults says franklin roosevelt was the best president since world war ii. the probability that at least one of the two adults says franklin roosevelt was the best president since world war ii is (round to three decimal places as needed.) (d) which of the events can be considered unusual? explain. select all that apply. the event in part left parenthesis a right parenthesis is unusual because its probability is less than or equal to 0.05. the event in part (b) is unusual because its probability is less than or equal to 0.05. none of these events are unusual. the event in part (c) is unusual because its probability is less than or equal to 0.05.

Divide. reduce the answer to lowest terms.5 2/3 ÷ 3 1/9
