18,38,38,40,44,44,44,46,48....
the mean with the outlier (18) included is : 360/9 = 40
38,38,40,44,44,44,46,48
the mean with the outlier (18) excluded is : (360 - 18) / 9 = 342/9 = 38
so when the outlier is removed, the mean is 2 points less
3.95 × 3.81 = 15.0485
The road was 15.0485 miles long after the renovation.
Hope this helps!
=0 just need points tho lol
Answer:the hardest questiom
Step-by-step explanation:
Answer:
ƒ(x) = (x - 8)² - 1
Step-by-step explanation:
Start with the basic function: f(x) = x².
To shift the parabola <em>eight units to the left</em>, you must <em>add eight units</em> to the value of x. The equation for the parabola becomes
ƒ(x) = (x - 8)².
To shift the parabola down one unit, you <em>subtract one unit</em> from the function. The equation becomes
ƒ(x) = (x -8)² - 1.
The figure below shows the graphs of ƒ(x) = x² (red), ƒ(x) = (x - 8)² (blue), and ƒ(x) = (x - 8)² - 1 (green).
