Answer:

B. 2005

Step-by-step explanation:

We have been given that population of deer in a certain national park can be approximated by the function P(x)=150(1.07)^x, where x is the number of years since 1995. We are asked to find the year in which population will reach 300.

To solve our given problem, we will equate P(x)=300 and solve for x as:

300=150(1.07)^x

\frac{300}{150}=\frac{150(1.07)^x}{150}

2=(1.07)^x

Now, we will take natural log on both sides as:

\text{ln}(2)=\text{ln}((1.07)^x)

\text{ln}(2)=x\text{ln}(1.07)

x=\frac{\text{ln}(2)}{\text{ln}(1.07)}

x=10.2447

x\approx 10

Now, we will find 10 years after 1995 that is 1995+10=2005.

Therefore, the population will be 300 in year 2005 and option B is the correct choice.

Answer:

b. 2005

Step-by-step explanation:

(apex)

300=150(1.07)^x

1.07^x=2

x=ln 2/ln 1.07

=10.24

1995 plus ten years = 2005

hope this helps

Wittaler [7]

Answer:

46.22

Step-by-step explanation:

Class A total= 23 x 13= 299

Clas B total= 57 x 28= 1596

total score= 299 + 1596 = 1895

total mean= 1895 ÷ (13+28) = 1895 ÷ 41

                 = 46.22
