Astudy of the adequacy of new york city’s snow-fighting capability estimated that the number of snowstorms in a season was approximately (remember the continuity approximation) normally distributed with a mean of 6.5 and a standard deviation of 2.25. how often does new york city have more than 10 snowstorms in a season? assuming independence, what is the probability that new york city will have more than 10 snowstorms in at least two of the next three seasons?

What is always true when two whole numbers are subtracted?

Christine wong has asked dave and mike to her move into a new apartment on sunday morning. she has asked them both, in case one of them does not show up. from past experience, christine knows that there is a 40% chance that dave will not show up and a 30% chance that mik a. what is the probability that both dave and mike will show up? (round your answer to 2 decimal places.) b. what is the probability that at least one of them will show up? c. what is the probability that neither dave nor mike will show up? (round your answer to 2 decimal places.)e will not show up. dave and mike do not know each other and their decisions can be assumed to be independent.

Which sum or difference identity would you use to verify that cos (180° - q) = -cos q? a.) sin (a -b) = sin a cos b – cos a sin b b.) cos (a -b) = cos a cos b – sin a sin b c.) cos (a -b) = cos a cosb + sin a sin b d.) sin (a + b) = sin a cos b + cos a sin b
