Amedication is administered with a dose of 10 milligrams. after 3 hours there are 6.5 milligrams in the patients system, due to half-life of 4.8 hours. this situation can be modeled by the formula: y=10e-0.1436t. how much of the medication will remain in the patients system after 8 hours. round to the nearest hundredth of a milligram.

solution:

as, mean is defined as sum of all the observations divided by total number of observations.

and , median is mid value of the data whether arranged in ascending order or descending order.

consider, roadsters:

2,3,4,5,6,7,8,9

mean =

also, median= , because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean =  

median = 4, as number of observations is odd.

so, roadsters has greater median as well mean than bandits.

→option a is true about the repairs performed on 2 types of cars:

bandits have lower median and mean than roadsters.

55 because 55 + 55 = 110 good luck babe

time is equal to distance over rate so

t = d/r

need a little bit more information for the second question.
