Adrian is using an indirect method to prove that segment de is not parallel to segment bc in the triangle abc shown below:

a triangle abc is shown. d is a point on side ab and e is a point on side ac. points d and e are joined using a straight line. the length of ad is equal to 5, the length of db is equal to 3, the length of ae is equal to 6 and the length of ec is equal to 4.

he starts with the assumption that segment de is parallel to segment bc.

which inequality will he use to contradict the assumption?

5: 3 ≠ 6: 10
5: 8 ≠ 6: 4
5: 8 ≠ 6: 10
5: 3 ≠ 5: 6

Which term best describes the association between variables a and b

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.

Players on the school soccer team are selling candles to raise money for an upcoming trip. each player has 24 candles to sell. if a player sells 4 candles a profit of$30 is made. if he sells 12 candles a profit of $70 is made. determine an equation to model his situation?
