Two hundred ten balloons are filled for a reception. This is 70 percent of the entire number of balloons purchased. Which equation can be used to find the total number of balloons purchased?
StartFraction 210 divided by 3 Over 100 divided by 3 EndFraction = StartFraction 70 Over 33.3 EndFraction
StartFraction 70 times 3 Over 100 times 3 EndFraction = StartFraction 210 Over 300 EndFraction
StartFraction 100 divided by 3 Over 210 divided by 3 EndFraction = StartFraction 33.3 Over 70 EndFraction
StartFraction 70 times 3 Over 210 times 3 EndFraction = StartFraction 210 Over 630 EndFraction

Which equation represents a proportional relationship that has a constant of proportionality equal to 1/5

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.
