Monica and Lauren plan to buy some of their dry ingredients (particularly flour, sugar, and baking soda) in prepackaged containers. Each container with the three dry ingredients weighs
22 pounds. The weight of the sugar in each container is 2 times the amount of baking soda.
Also, there are 14 pounds more flour than baking soda in each container.
The girls want to calculate the weight of baking soda in each container, but they claim that the
necessary equation is impossible because it has infinitely many solutions.
Identify an equation that proves the girls' claim is wrong and explain why that equation does not
have infinitely many solutions.

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?
