For reasonable distances, a certain jogger can maintain an average speed of 6 miles per hour while running on level ground. the jogger decides to go to a local park and use one of the paths there for a workout routine one day each week. this path is a gently sloping one that winds its way to the top of a hill. 1. the jogger can run at an average speed of 5.5 miles per hour up the slope and 6.5 miles per hour going down the slope. the jogger decides to cover 2 miles by going uphill for 1 mile and then returning 1 mile back down the hill. a. how long does it take the jogger to run 1 mile uphill? __ (hint: use the formula d = rt.) b. how long does it take the jogger to run 1 mile downhill? (hint: use the formula d = rt.) c. use your answers to a and b to determine how long, in hours, the full trip will take (1 mile uphill and 1 mile downhill). give an exact answer expressed as a fraction in simplest terms and then give a decimal approximation correct to three decimal places. reduced fraction: decimal approximation:

1.3.25 question suppose 40​% of all voters voted for a particular candidate. to simulate exit polls regarding whether or not voters voted for this​ candidate, five random samples of size 1010 and five random samples of size 10001000 have been generated using technology using a population proportion of 0.400.40​, with the accompanying results. complete parts a through c below. click the icon to view the simulation results. a. observe how the sample proportions of successes vary around 0.400.40. simulation compared to sample prop simulation compared to sample prop 1 ▾ 6 ▾ greater than 0.40 less than 0.40 equal to 0.40 2 ▾ less than 0.40 greater than 0.40 equal to 0.40 7 ▾ greater than 0.40 less than 0.40 equal to 0.40 3 ▾ greater than 0.40 less than 0.40 equal to 0.40 8 ▾ equal to 0.40 greater than 0.40 less than 0.40 4 ▾ greater than 0.40 equal to 0.40 less than 0.40 9 ▾ less than 0.40 greater than 0.40 equal to 0.40 5 ▾ equal to 0.40 less than 0.40 greater than 0.40 10 ▾ equal to 0.40 greater than 0.40 less than 0.40 click to select your answer(s) and then click check answer. 2 parts remaining clear all check answer
