Answer:
The slope of the regression line is 0.01.
Step-by-step explanation:
The given regression equation for this bird is
.... (1)
where, DD is dive duration measured in minutes, and D is depth in meters.
The slope intercept form of a line is
.... (2)
where, m is slope and b is y-intercept.
On comparing equation (1) and (2), we get
Since, m=0.01, therefore the slope of the regression line is 0.01.
81 x 31 = 2 511 (area of a brick)
2511 x 400 = 1 004 400 (area of the wall)
Convert 1 004 400" to ft. [1ft. = 12"]
1 004 400 / 12 = 83 700 ft.
Now this is what we have.
-Hight 42 ft.
-Length X ft.
-Area 83 700ft.
Algebra time.
42 x X = 83 700 (to get X you would devide 83 700 by 42)
83 700 / 42 = 1 992.85ft. (X = 1 992.85ft.)
So the length of the wall would be 1992.85ft.
