Please answer with correct answers thank you... 6-7

6.  300/4 feet per hour or feet/hour

7. 90/10 feet per second or feet/sec

Try simplifying the fractions though.  

Step-by-step explanation:

average rate of change just means the change in distance per the change in time (per meaning divided by).  what is the change in distance?  700-400 = 300.  change in time is 6-2 = 4 hours. so 300/4  

Same thing, change in distance is 100 - 10 feet and change in time is 40-30 seconds so the average rate of change is 90/10 feet per second

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 %
