Ms. Rodriguez purchased markers to use on her class whiteboard. She bought a total of 16 markers and three times as many blue markers as red markers.
Set up the two equations that can be used to find the number of markers of each color that Ms. Rodriguez purchased.
. Let constraint 1 refer to the equation that represents the total number of markers.
• Let constraint 2 refer to the equation that describes the ratio of the number of blue markers to red markers.
would be met if Ms. Rodriguez purchased 3 red markers and 9 blue markers.

would be met if Ms. Rodriguez purchased 6 red markers and 10 blue markers.

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?
