Each of three friends flips a coin 76 times. The results for each friend are shown in the tables. Find
the relative frequency for the event "tails for each friend. If the friends combine their results to get
142 heads and 86 tails, what is the relative frequency for the event tails? Use pencil and paper.
Suppose each friend flips a coin 760 times. Is there a value you would expect the relative frequency
for the event "tails" to be close to?

News cameras take an overhead picture of a crowd at an outdoor event journalist then count the total number of people in the picture and use the sample of estimate the total number of people in the crowd this process is an example of

Ataxi company charges $2.25 for the first mile and then $0.20 per mile for each additional mile, or f = $2.25 + $0.20(m - 1) where f is the fare and m is the number of miles. if juan's taxi fare was $6.05, how many miles did he travel in the taxi? if juan's taxi fare was 7.65, how many miles did he travel in taxi
