Answer:
c. 60.9%
Step-by-step explanation:
Given:
The probability P that a person responds to an advertisement can be modeled by the function:
where 
represents number of days since the advertisement first appeared.
To find the probability that a person has responded after 20 days.
Solution:
In order to find the probability that a person has responded after 20 days, we will plugin 
in the formula given.
We have:
Plugging in
Thus, probability 
after 20 days = 0.6094
The probability in percentage can be given = 
= 60.9%

Answer:
300 meters per minute
Step-by-step explanation:
Step 1
Determine the fraction of the total distance for each part of the race.
Given:
1st part of race = 4/9 of total distance
2nd part of race = 2/5 of remaining distance
Step 2
Determine the distance of the third part of the race.
Given:
time = 15 minutes
speed = 300 meters per minute
Step 3
If the third part of the race (which is 1/3 of the total distance) is 4500m, then the distance of the whole race is:
Step 4
Determine the distance of the 1st part of the race:
Step 5
Determine the speed of the 1st part of the race:
Given:
time = 20 minutes
distance = 6000 m
