Use the image below to answer the following question:

A right triangle is shown. The two angles that are not 90 degrees are marked x and y. The leg across from angle y measuring 9, another leg across from angle x measuring 12, and the hypotenuse measuring 15.

What relationship do the ratios of sin y° and cos x° share?

The ratios are both identical. (9 over 15 and 9 over 15)
The ratios are opposites. (negative 9 over 15 and 9 over 15)
The ratios are reciprocals. (9 over 15 and 15 over 9)
The ratios are both negative. (negative 15 over 9 and negative 9 over 15)

Which compound inequality can be used to solve the inequality 3x+2 > 7? -7 < 3x+2> 7 -7> 3x+27 3x + 2 > -7 or 3x + 2 > 7 3x + 2 < -7 or 3x + 2 > 7

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.
