A newspaper regularly reports the air quality index for various areas of Southern California. A sample of air quality index values for Pomona provided the following data: 29, 43, 58, 49, 46, 56, 60, 49, and 51.

35 is an outlier

step-by-step explanation:

x = 12

y = 1

for the points!

ending amount = beginning amount / (2^n)

where "n" = number of half-lives (or elapsed time / half-life)

ending amount = 50 mg / (2 ^10 / 5.3)

ending amount = 50 mg / (2 ^ 1.8867924528)

ending amount = 50 m / 3.6981210597

ending amount = 13.5203794557 mg

or about 13.5 mg remain
