The probability, P, that a person responds to an advertisement can be modeled by the exponential function P = 1 – e^-0.047t. In
Ray Of Light [21]

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:

P=1-e^{-0.047t}

where t 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 t=20 in the formula given.

We have:

P(t)=1-e^{-0.047t}

Plugging in t=20

P(20)=1-e^{-0.047(20)}

P=1-e^{-0.94}

P=1-e^{-0.047t}

P=1-0.3906

P=0.6094

Thus, probability P after 20 days = 0.6094

The probability in percentage can be given = 0.6094\times 100= 60.9%

IrinaVladis [17]

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
