Arope runs through a pulley 3.05 m off the ground. one end hangs straight down and is attached to a car's engine that is being hoisted. the other end is attached 0.61m off the ground to the rear bumper of another car. the car drives away at 4 km/h. how fast, in m/s, is the rope going through the pulley when the car's rear bumper is 4.88m from being under the pulley? the rope is long enough so that the engine is between the ground and the pulley.

In triangle opq right angled at p op=7cm,oq-pq=1 determine the values of sinq and cosq

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:
