Rowan tosses a ball toward his opponent during a game of table tennis. function h demonstrates the height of the ball, in meters, when it is a distance x meters away from rowan. h(x) = -1/4x^2 + 1/2x + 1/2 select the statement that accurately describes the maximum point of the graph modeling the height of the ball. a. the maximum height of the ball is 0.75 of a meter, which occurs when it is approximately 1 meter away from rowan. b. the maximum height of the ball is 2.73 meters, which occurs when it is approximately 1 meter away from rowan. c. the maximum height of the ball is 1 meter, which occurs when it is approximately 0.75 of a meter away from rowan. d. the maximum height of the ball is 1 meter, which occurs when it is approximately 2.73 meters away from rowan. reset next

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:
