Runner = 5 mph
bicyclist...4 times the runner....4(5) = 20 mph
20 - 5 = 15 mph <== the difference
Answer:
Step-by-step explanation:
Each point of function b(x) is shifted by rule
x -----> ( x - 2 )
and
y -----> (y + 3)
( - 1.5, 0) ------> (- 3.5, 3)
(- 1, - 1) -----> ( - 3, 2)
(0, - 2) ------> ( - 2, 1)
(1, - 1) -----> ( - 1, 2)
(2, 3) -----> (0, 6)
(4, 7) -----> (2, 10)
......
Answer:
The z-scores of both the mean and the median are zero.
Step-by-step explanation:
In a normal distribution, the mean and median values will be the same, in this case, 100. Therefore, both the mean and median will have the same score.
The z-score is given by:

For X = 100:

The z-scores of both the mean and the median are zero.
36 for the first one 39 for the second one
Answer:
567 mph
Step-by-step explanation:
The speed will actually just be the slope of the line. Slope is change in y-coordinates over change in x-coordinates. We can pick any two points for this; let's just do (1, 567) and (2, 1134).
Slope = (1134 - 567) / (2 - 1) = 567 / 1 = 567
The speed is thus 567 miles/hour.
