An artist prints T-shirts to sell at a fair for $14 each. The artist has some initial T-shirts ready to sell and works for h hours more, printing a constant number of T-shirts every hour. The expression 14(12h+30) represents the amount, in dollars, the artist will earn selling all the T-shirts. Part B Which statement about (12h+30) is true? The value 12 is a coefficient, and the value 30 is a constant in the expression (12h+30). The value 12 is a coefficient, and the value 30 is a constant in the expression ( 12 h + 30 ) . The value 12 is a constant, and the value 30 is a coefficient in the expression (12h+30). The value 12 is a constant, and the value 30 is a coefficient in the expression ( 12 h + 30 ) . The values 12 and 30 are both coefficients in the expression (12h+30). The values 12 and 30 are both coefficients in the expression ( 12 h + 30 ) . The values 12 and 30 are both constants in the expression (12h+30). The values 12 and 30 are both constants in the expression ( 12 h + 30 ) .

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?
