Suppose that the concentration (measured in gm^-3) of nitrogen in the soil along a transect in moist tundra yields data points that follow a straight line with equation y = 673.8 - 34.7x for 0 (is less than or greater to) x (is less than or greater to) 10, where x is the distance to the beginning of the transect.
what is the average concentration of nitrogen in the soil along this transect?

Ответ:
The average concentration of nitrogen in the soil along 0 ≤ x ≤ 10 is![y_{avg}=500.3 \:{\frac{g}{m^3} }](/tpl/images/0421/5786/78e6a.png)
Step-by-step explanation:
To find the average concentration between two points a and b along a transect, we measure the concentration at equal distances. Assume that f(x) is a continuous function on [a, b]. The average value of f on the interval [a, b] is
To find the average concentration of nitrogen we have to take the integral over the entire range and then dividing by the distance covered in the study.

Markdown: 71% × 202.11
0.71 × 202.11 = 143.4981
143.4981 ≈ 143.50
Markdown ≈ $143.50
Sale price: Original price - Markdown
$202.11 - $143.50 = $58.61
