In a certain city, a man recorded the speeds of cars driving past his house, where the speed limit sign read 20 mph. The mean of 100 readings was 23.56 mph,
with a standard deviation of 3.67 mph. One car's z-score was +2.3. How fast
was that car going?

step-by-step explanation:

just plug in each number for x and see which ones work and don't

amount of oatypop that contains the prize = 40%

amount   of oatypop which doesn't contain the prize = (100-40)=60%

probability that hannah will win a prize

    = s +f s +f f s+ff   f s+ff f f s+ infinity.where f= failure,s= success

=   or 60%

probability that hannah only has to buy 3 or less boxes before getting a prize= (s) and ( f s) and (ff s) and (f f f s)

        = = 87.04 %
