In city a, the temperature rises 4 degrees °f from 8 a. m. to 9 a. m. then the temperature drops 7 degrees °f from 9 a. m. to 10 a. m. in city b, the temperature drops 6 degrees °f from 8 a. m. to 9 a. m. then the temperature drops 2 degrees °f from 9 a. m. to 10 a. m. write an expression that represents the change in temperature from 8 a. m. to 10 a. m. for each city. simplify and interpret each sum. use pencil and paper. which city has the greater change in temperature?

What are the constants in this expression? -10.6+9/10+2/5m-2.4n+3m

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.

There is a spinner with 14 equal areas, numbered 1 through 14. if the spinner is spun one time, what is the probability that the result is a multiple of 2 or a multiple of 5?
