Answer:
As the wheel makes this 270 degree counterclockwise rotation about the origin, the y-coordinate of the first car decreases from 80 to 0 and then further from 0 to -80, and finally increases to 0.
The x-coordinate decreases from 0 to -80 and then increases to 0; from there it increases further to 80.
Thus, the coordinates of the first car, after this 270-degree rotation, are (80, 0).
Answer:
Axis of symmetry is different, one's slope is positive while the other is negative, the red parabola has zeros whilst the blue doesn't, and different y-intercepts.
They are both parabolas, they have a vertex, both have y-ints, etc.
I'll assume that's
Please let me know if that's wrong.
These are two lines in point slope form. They'll meet at some x that makes the ys equal.
is the only solution.
Exactly one solution.
We really only had to ensure the lines had two different slopes. Then there's always exactly one solution.
If the lines had the same slope, they're either the same line (coincident) so an infinite number of solutions, all the points on that line, or they're parallel, no solutions.

The numbers are between +/- 2 sd s of the mean
With Chebyshev's inequality, at least 3/4 of the numbers would be between these two.
For the one with 3 standard deviations, it would be 8/9.
----------------------
For the second part, this is 3.5 sd s on either side
1/(3.5)^2=0.0816, The fraction is 1/(49/4) or 4/49.
----------------
The second one would be wishing 18/8 or 2.25 sd s and that fraction would be 1/(9/4)^2=1/81/16 or 16/81 or 0.1975.
