Suppose in 1970 there were 1.3 million college degrees awarded. This number increased to 2.5 million in 2010. (a) Find a linear function D that approximates degree
numbers in millions x years after 1970.
(b) Interpret the y-intercept on the graph of D.
(c) Estimate symbolically when this number was 2.2 million.
(a) D(x) =
(Use integers or decimals for any numbers in the expression.)

Subtract 8 1/6 - 4 5/6 . simplify the answer and write as a mixed number.

Acircle has a diameter will endpoints of (-2,8) and (6, 4). what is the center of the circle

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?
