Abox containing a total of 179 copies of two different paperback books was shipped to marci’s school. the total weight of the books was 128 pounds. if the weight of each of the first paperbacks was 2/3 of a pound and the weight of each of the second paperbacks was 3/4 of a pound, which statements are true? check all that apply.
1. the system of equations is x + y = 179 and 2/3x+3/4y=128
2. the system of equations is x + y = 128 and 2/3x+3/4y=179
3. to eliminate the x-variable from the equations, you can multiply the equation with the fractions by 3 and leave the other equation as it is.
4. to eliminate the y-variable from the equations, you can multiply the equation with the fractions by –4 and multiply the other equation by 3.
5. there are 104 copies of one book and 24 copies of the other.
6. there are 93 copies of one book and 35 copies of the other.
7. there are 104 copies of one book and 75 copies of the other.
8. there are 93 copies of one book and 86 copies of the other.

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.
