Blake took his motorboat, which travels 36 miles per hour in still water, on a river. He traveled downstream (i. e., with the current) for 6 minutes. Then he turned off the motor and drifted with the current for 30 minutes. Finally, he turned his motor back on, turned around, and traveled upstream (i. e., against the current) for 15 minutes. Fill in the table below to find expressions for the number of miles Blake traveled downstream with his motor on, downstream with his motor off, and upstream. Use x to represent the current's speed in miles per hour.

In tossing one coin 10 times, what are your chances for tossing a head? a tail? 2. in tossing one coin 100 times, what are your chances for tossing a head? a tail? 3. in tossing one coin 200 times, what are your chances for tossing a head? a tail? deviation = ((absolute value of the difference between expected heads and observed heads) + (absolute value of the difference between expected tails and observed tails)) divided by total number of tosses. this value should always be positive. 4. what is the deviation for 10 tosses? 5. what is the deviation for the 100 tosses? 6. what is the deviation for 200 tosses? 7. how does increasing the total number of coin tosses from 10 to 100 affect the deviation? 8. how does increasing the total number of tosses from 100 to 200 affect the deviation? 9. what two important probability principles were established in this exercise? 10. the percent of occurrence is the obtained results divided by the total tosses and multiplied by 100%. toss the coins 100 times and record your results. calculate the percent occurrence for each combination. percent head-head occurrence: percent tail-tail occurrence: percent head-tail occurrence:
