Arental car company offers two rental plans, plan a and plan b, for the same economy size car. for both plans, the total rental cost, ƒ(m) is a function of the number of miles, m, that the car is driven. in addition to a flat fee of $75, plan a offers a rate of $0.20 per mile for an unlimited number of miles. plan b offers a higher mileage rate of $0.35 per mile but does not charge a flat fee for the rental. 1.create a system of linear functions modeling the cost of the car rental plans, a and b, as a function of the miles driven. 2.for how many miles, m, will the rental fee be the same under both plans a and b

Which expression is equivalent to 8(k + m) − 15(2k + 5m)?

It appears that people who are mildly obese are less active than leaner people. one study looked at the average number of minutes per day that people spend standing or walking. among mildly obese people, the mean number of minutes of daily activity (standing or walking) is approximately normally distributed with mean 376 minutes and standard deviation 64 minutes. the mean number of minutes of daily activity for lean people is approximately normally distributed with mean 528 minutes and standard deviation 107 minutes. a researcher records the minutes of activity for an srs of 7 mildly obese people and an srs of 7 lean people. use z-scores rounded to two decimal places to answer the following: what is the probability (image for it appears that people who are mildly obese are less active than leaner people. one study looked at the averag0.0001) that the mean number of minutes of daily activity of the 6 mildly obese people exceeds 420 minutes? what is the probability (image for it appears that people who are mildly obese are less active than leaner people. one study looked at the averag0.0001) that the mean number of minutes of daily activity of the 6 lean people exceeds 420 minutes?
