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%

Solving Quadratic Equations by completing the square<br><br> xz^2 - 3z - 5 =0
Andrei [34K]

Answer:

x=3z+5

/z^2

Step-by-step explanation:

Let's solve for x.

xz^2−3z−5=0

Step 1: Add 5 to both sides.

xz^2−3z−5+5=0+5

xz^2−3z=5

Step 2: Add 3z to both sides.

xz^2−3z+3z=5+3z

xz^2=3z+5

Step 3: Divide both sides by z^2.

xz^2

/z^2

=

3z+5/

z^2

x=

3z+5

/z^2

Answer:

x=3z+5

/z^2
