For this case, what can be observed is a decrease in time by increasing the number of races in which it competes.
If you have competed in a race:
f = -0.45 * (1) +43.6
f = 43.15 min (arrival time).
If you have competed in two races:
f = -0.45 * (2) +43.6
f = 42.7 min (arrival time).
answer:
The model predicts that for each additional race a bicyclist has competed in, the finishing time decreases by about 0.45 minutes.
Answer:
x=-5
Step-by-step explanation:
The turning point is at x=-5 and thus is the axis of symmetry.
25%
Explanation: it increased 4$ and 4$ is 25% of 16$
