Science 10 ! the greenhouse effect traps heat near earth's surface. greenhouse gases in the atmosphere—carbon dioxide, water vapor, methane, and nitrous oxide—allow the shorter waves of ultraviolet radiation from the sun to enter earth's lower atmosphere. however, these gases do not allow the longer wavelengths of infrared radiation to pass back out to the outer atmosphere. the result is that the lower atmosphere heats up. this result happens naturally, but it can be accelerated by human activities. since the late 1800s, human activity has greatly altered the amount of greenhouse gases that enter the atmosphere. burning fossil fuels, farming, and clearing forests, as well as industry, have all contributed to increases of carbon dioxide (co2), methane, nitrous oxide, and other greenhouse gases in the atmosphere. the result is that temperatures in the troposphere have gone up. many scientists identify this increase in greenhouse gas emissions as contributing directly to global warming. this suggests that human activity has had an impact on the global climate. the author argues that in modern times, the greenhouse effect * a. keep the earth warm b. has increased because of human activity c. is in a natural cycle of changing d. has changed local weather patterns

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.

Money off coupons have been circulated to 300 households. only 2/5 of these were redeemed (used) in the local supermarket to get a free shampoo. what fraction of coupons were unused? (ps: write how you got the answer)
